     1. Introduction
     
     The SatLabs Group [SATLABS] is an international non-profit EEIG
     (European Economic Interest Grouping) committed to large-scale adoption
     and deployment of the Digital Video Broadcasting Return Channel via
     Satellite (DVB-RCS) standard [ETSI-RCS]. SatLabs members are service
     providers, satellite operators, system integrators, terminal
     manufacturers and technology providers with an interest in DVB-RCS.
     
     Since its creation in 2001, the main goal of the SatLabs Group has been
     to achieve interoperability between DVB-RCS terminals and systems.
     Therefore, the Group has defined the SatLabs Qualification Program that
     provides an independent certification process for DVB-RCS Terminals
     based on System Recommendations defined by SatLabs. To enhance products
     interoperability, beyond the physical and MAC layer mechanisms defined
     in the DVB-RCS standard, SatLabs has expanded its Recommendations in the
     field of DVB-RCS terminal management [SATLABS]. As a part of this
     effort, SatLabs has specified a common SNMP Management Information Base
     (MIB) for DVB-RCS terminals, which is defined in this document.
     
     A DVB-RCS terminal is denoted as a Return Channel Satellite Terminal
     (RCST) in the remainder of this document. This consists of an Indoor
     Unit (IDU) and an Outdoor Unit (ODU) connected through an Inter Facility
     Link (IFL), usually a coaxial L-band interface. On the user side, the

     IDU is connected to the user network through a Local Area Network (LAN)
     interface (usually Ethernet). On the network side, the ODU is connected
     via a satellite link (the Air Interface).
     
     The DVB-RCS MIB is implemented in the IDU of an RCST. RCST management
     can be performed either through the LAN interface (Local management) or
     through the Air Interface (Remote management from the Network Control
     Center, NCC). RCST and NCC elements are shown in Figure 1.

        The terms in this document are derived either from DVB-RCS standard
        specifications [ETSI-RCS] or from SatLabs System Recommendations
        [SATLABS].
     
     2.2.1. Star DVB-RCS network
     
        This denotes a hub-and-spoke configuration where all communications
        pass through a central hub, that usually also includes the NCC. Peer-
        to-peer communication between RCSTs is possible, but through a double
        satellite hop (this traffic has to pass through the hub).
     
     2.2.2. Mesh DVB-RCS network
     
        This denotes a mesh configuration that supports peer-to-peer
        communications in a single satellite hop directly between RCSTs.
     
     2.2.3. Transparent DVB-RCS network
     
        This denotes a network using transparent satellite transponders. Star
        or mesh network configurations can be supported. In the case of a
        mesh configuration, RCSTs need to incorporate a TDMA receiver in
        addition to the TDM receiver.

     2.2.4. Regenerative DVB-RCS network
     
        This denotes a network using regenerative satellite transponders,
        i.e. including some On-Board Processing functionality allowing
        demodulation and decoding of the uplink TDMA signals and re-multiplex
        the traffic on the downlink. Star or mesh network configurations can
        be supported.
     
     2.2.5. DVB-RCS MAC layer
     
        The DVB-RCS MAC Layer represents the air interface of an RCST, as
        defined in the DVB-RCS standard. The interface supports star and mesh
        networks and is bi-directional.
     
     2.2.6. DVB-RCS Downlink
     
        The downlink is a DVB-RCS physical link based on TDM. It corresponds
        to the forward link of a DVB-RCS transparent system or the downlink
        of a DVB-RCS regenerative system. It is based on either the DVB-S or
        DVB-S2 standard. In the DVB-RCS context, this interface is bi-
        directional.
     
     2.2.7. DVB-RCS Uplink
     
        The DVB-RCS Uplink is based on TDMA. It corresponds to the return or
        mesh link of a RCS transparent system or the uplink of a RCS
        regenerative system. It is based on the DVB-RCS standard.
     
        In the context of star transparent and mesh regenerative DVB-RCS
        systems, this interface is uni-directional.
     
        In the context of mesh transparent DVB-RCS systems, this interface is
        bi-directional.
     
     2.2.8. IDU
     
        This is the indoor part of the RCST (including at least the power
        supply, and usually also the modem and networking functions).
     
     2.2.9. ODU
     
        This is the outdoor part of the RCST (including at least the aerial,
        and usually also the LNB and BUC).

     2.2.10. RCST
     
        This is the Satellite Terminal, installed on the customer premises.
        It is composed of the IDU and ODU.
     
     2.2.11. NCC
     
        The NCC provides Control and Monitoring Functions. It generates
        control and timing signals for the operation of the DVB-RCS Network.
     
     2.2.12. Configuration file
     
        The configuration file is XML formatted file, storing configuration
        parameters for the RCST and their values.
     
     2.2.13. Logfile
     
        The logfile is stored at the RCST. This is used to log particular
        events that occurr on RCST side.
     
     2.2.14. InstallLogfile
     
        The Installlogfile is stored at the RCST. This logs particular events
        that occur on RCST side, related to RCST installation phase.
     
     2.2.15. Antenna alignment
     
        This is the process to align the RCST antenna, part of the ODU, in
        order to enable bi-directional communication (uplink, downlink) with
        the satellite network.
     
     2.2.16. CW frequency
     
        The CW frequency is the frequency of a Continuous Wave signal. It is
        a narrowband carrier transmitted for the duration of measurements
        during the installation of a RCST.
     
     2.2.17. Request Class
     
        A Request Class (RC) is a representation of a Per Hop Behavior (PHB)
        at the MAC layer. It defines a behavior of the MAC layer for a given
        aggregation of traffic. This behavior includes a combination of
        Capacity Categories associated to the RC and a Priority with respect
        to the other RCs supported by a RCST.

     Internet-Draft               DVB-RCS MIB                      July 2008
     
     
     2.2.18. Channel ID
     
        Each Request Class is identified by a unique Channel_ID in the
        communication between the RCST and the NCC.
     
     2.2.19. ATM profile
     
        The ATM profile is one of the two profiles for traffic burst format
        on a DVB-RCS uplink. It is based on one or more concatenated ATM
        cells, each of length 53 bytes, plus an optional prefix.
     
     2.2.20. MPEG profile
     
        The MPEG profile is one of the two profiles for traffic burst format
        on the DVB-RCS uplink. It is based on a number of concatenated MPEG2-
        TS packets, each of length 188 bytes.
     
     2.2.21. PID pool
     
        For the MPEG profile several RCs may be mapped within a pool of
        several PIDs to allow cross-RC Section Packing [RFC4259]. Section
        packing can be used on all PIDs and higher priority traffic can
        always pre-empt lower priority streams. This reduces the need for
        padding.
     
     2.2.22. Capacity Categories
     
        The TDMA timeslot allocation process for the DVB-RCS uplink supports
        several capacity categories.
     
        The Capacity Categories CRA, RBDC and A/VBDC, when authorized for a
        RC, have to be configured from the NCC. These configuration
        parameters are used to inform the RCST of the configuration of each
        Category at the NCC side and thus help in Capacity Requests
        computation.
     
        The configuration of these parameters is performed for each RC. A
        SatLabs option is defined that allows their configuration at the RCST
        level in addition to configuration per RC. This option is denoted
        RCST_PARA.
     
     2.2.22.1. Continuous Rate Assignment (CRA)
     
        CRA is a rate capacity that is provided in full in a continuous
        manner to the RCST while required.

     2.2.22.2. Rate-Based Dynamic Capacity (RBDC)
     
        RBDC is rate capacity that is requested dynamically by an RCST. RBDC
        capacity is provided in response to explicit requests from the RCST
        to the NCC, such requests being absolute (i.e. corresponding to the
        full rate currently being requested). Each request overrides all
        previous RBDC requests from the same RCST, and is subject to a
        maximum rate limit.
     
     2.2.22.3. Volume-Based Dynamic Capacity (VBDC)
     
        VBDC is volume capacity that is requested dynamically by an RCST.
        VBDC capacity is provided in response to explicit requests from the
        RCST to the NCC, such requests being cumulative (i.e. each request
        adds to all previous requests from the same RCST).
     
     2.2.22.4. Absolute Volume-Based Dynamic Capacity (AVBDC)
     
        AVBDC is volume capacity that is requested dynamically by an RCST.
        This capacity is provided in response to explicit requests from the
        RCST to the NCC, such requests being absolute (i.e. this request
        replaces the previous ones from the same RCST).
     
        The combination of AVBDC and VBDC is seen as a single Capacity
        Category, denoted A/VBDC.
     
        A SatLabs Option is defined which allows AVBDC requests to be sent
        periodically, as defined by the AVBDCrepTime parameter. This option
        is denoted AVBDC_REP.
     
     2.2.22.5. Population ID
     
        This defines a group of RCSTs within a Network.
     
     2.2.23. Start transponder
     
        This is the satellite transponder on which the communication is
        initiated from a RCST point-of-view when in the installation mode.
        The parameters corresponding to this transponder (satellite orbital
        position, frequency, etc.) are stored at the RCST as power-up
        configuration data.
     
     2.2.24. DVB-S
     
        DVB-S is the Digital Video Broadcast over Satellite [ETSI-DVBS]. It
        is a framework and set of associated standards published by ETSI for

        the transmission of video, audio, and data, using the ISO MPEG-2
        Standard [ISO-MPEG], over satellite links.
     
     2.2.25. DVB-S2 and CCM/VCM/ACM
     
        DVB-S2 is the Second Generation of the Digital Video Broadcast for
        Satellite applications standard [ETSI-DVBS2]. It is a framework and
        set of associated standards published by ETSI for the transmission of
        video, audio and data.
     
        BBFRAME: The main framing unit of the DVB-S2 protocol stack.
     
        CCM: In CCM transmission mode, the forward link uses a constant set
        of transmission parameters (FEC coding rate and modulation scheme)
        for all receivers.
     
        VCM: In VCM transmission mode, the forward link uses transmission
        parameters which are variable on a BBFRAME-by-BBFRAME, but fixed on a
        Receiver basis, according to fixed link and propagation conditions
        for each Receiver.
     
        ACM: In ACM transmission mode, the forward link uses transmission
        parameters which are dynamically adjusted on a BBFRAME-by-BBFRAME and
        Receiver-per-Receiver basis, according to actual link and propagation
        conditions.  In order to implement ACM, feedback from each Receiver
        has to be provided by DVB-RCS return channel.
     
     2.2.26. Interactive Network
     
        This is another name for a DVB-RCS based satellite network.
     
     3. MIB Module
     
        This MIB module provides a set of objects required for the management
        of SatLabs-compliant RCST.  The specification is derived from the
        parameters and protocols described in [SATLABS].
     
     
        The MIB module in this document uses the following OBJECT IDENTIFIER
        values as already assigned by IANA under the smi-numbers registry
        [IANA]:
     
                         +------------+---------------------------+
                         | Descriptor | OBJECT IDENTIFIER value   |

                     Table 1: Object Identifiers for the MIB
     
        These values have been assigned for this MIB under the 'mib-
        2.transmission' subtree.
     
     3.1. Textual Conventions
     
     
        This MIB module defines new textual conventions for RCST indications
        of capabilities defined by SatLabs, including profiles, options and
        optional features.
     
        systemSatLabsProfileMap represents the SatLabs profiles supported as
        defined in [SATLABS].
     
        systemSatLabsOptionMap represents the SatLabs options supported as
        defined in [SATLABS]. These are options that are used for the
        certification of SatLabs terminals. They represent important
        functionality, with impact on interoperability, and their support is
        advertised with the RCST certification level.
     
        systemSatLabsFeatureMap represents the SatLabs optional features
        supported as defined in [SATLABS]. These represent minor features,
        not necessary for interoperability. They are not used for the
        certification of SatLabs terminals.
     
     3.2. Structure of the MIB
     
        This MIB module is structured into two top-level groups:
     
        o The dvbrcsMIBobjects group includes all the managed objects of the
        DVB-RCS MIB.
     
        o The dvbrcsConformance group includes the compliance statements for
        DVB-RCS terminals that are compliant with [SATLABS]. The managed
        objects are grouped into formal object groups (i.e. units of
        conformance) according to the relation to specific SatLabs options or
        features. The conformance statements (MODULE-COMPLIANCE
        specification) are described within the rcstCompliance group while
        the units of conformance are described within the rcstGroups group.
        The dvbrcsMIBobjects group is further structured into three groups:
     
        o rcst
        o fwdLink
        o rtnLink.

        The rcst group covers management related to the RCST equipment. It is
        structured into six groups:
     
        o rcstSystem
        o rcstNetwork
        o rcstInstall
        o rcstQos
        o rcstControl
        o rcstState
        The fwdLink group covers management information related to the RCST
        forward link. It is structured into two groups:
        o fwdConfig
        o fwdStatus
        The rtnLink group covers management information related to the RCST
        return link. It is structured into two groups:
        o rtnConfig
        o rtnStatus
     
        Tables within each of these groups cover different functions like
        return link traffic management (packet classes, Request Classes, PID
        pools) and forward links configuration and status.
        Rows created automatically (e.g., by the device according to the
        hardware configuration) may and generally will have a mixture of
        configuration and status objects within them.  Rows that are meant to
        be created by the management station are generally restricted to
        configuration (read-create) objects.
        The MIB module finally includes a conformance section including
        conformance groups and compliance statements.
     
     
     
     3.3. Relationship to the Interfaces MIB Module
     
        This section clarifies the relationship of this MIB module to the
        Interfaces MIB [RFC2863]. Several areas of correlation are addressed
        in the following subsections. The implementer is referred to the
        Interfaces MIB document to understand the general intent of these
        areas.
     
        IANA has assigned three ifType labels for DVB-RCS. Each RCST MUST
        support at least the three following interfaces:
     
        o dvbRcsMacLayer (239), -- DVB-RCS MAC Layer
        DVB-RCS MAC Layer represents the air interface of a RCST, as defined
        in [ETSI-RCS]. This interface supports star and mesh networks and is

        bi-directional. Only star networks are considered by the present MIB
        module.
        o dvbTdm (240), -- DVB Satellite TDM
        DVB-RCS Physical link based on Time Division Multiplexing. It
        corresponds to the forward link of a RCS transparent system or the
        downlink of a RCS regenerative system. It is based on either DVB-S or
        DVB-S2 standard. Only transparent systems are considered by the
        present MIB module.
        In the DVB-RCS context, this interface is uni-directional (i.e.
        forward link, or downstream).
        o dvbRcsTdma (241), -- DVB-RCS TDMA
        DVB-RCS Physical link based on Time Division Multiple Access. It
        corresponds to the return or mesh link of a RCS transparent system or
        the uplink of a RCS regenerative system. It is based on the DVB-RCS
        standard.
        In the context of star transparent and mesh regenerative DVB-RCS
        systems, this interface is uni-directional.
        In the context of mesh transparent DVB-RCS systems, this interface is
        bi-directional.
        Only star transparent systems are considered by the present MIB
        module (i.e. return link, or upstream).
        The protocol stack (as reflected in ifStackTable) will be as follows:
        +--------------------------+
        +                IP        +
        +--------------------------+
        +      dvbRcsMacLayer      +

        +   MPEG/ATM    + MPEG/GS  +
        +---------------+----------+
                               FIGURE 2: RCST protocol stack
     
        GS (Generic Stream) is defined in [ETSI-DVBS2]. The additional
        Ethernet interface is used on the LAN side of the RCST. An instance
        of ifEntry exists for each DvbTdm interface, for each DvbRcsTdma
        (normally only one), and for each DvbRcsMac layer (normally only
        one).
     
        The interface counters relate to:
     
        o dvbRcsMacLayer: DVB-RCS two-way MAC that counts aggregate DVB-RCS
        SDU traffic (IP layer)
        o dvbTdm: DVB-RCS TDM that counts either Generic Stream Encapsulation
        (GSE) or Multi-Protocol Encapsulation (MPE) traffic, as applicable
        for the specific configuration
        * GSE is defined in [ETSI-GSE]

        * MPE is defined in [ETSI-DAT]
        o dvbRcsTdma: DVB-RCS TDMA that counts either ATM Adaptation Layer 5
        (AAL5) or MPE traffic, as applicable for the specific configuration
        The ifStackTable [RFC2863] MUST be implemented to identify the
        relationships among sub-interfaces.
     
        The following example considers an DVB-RCS star network with DVB-S
        and DVB-RCS. As illustrated on Figure 3, it shows a DVB-RCS MAC
        interface with one downstream and one upstream interfaces. In this
        network, ATM encapsulation is used in the DVB-RCS uplink. Two ATM
        Logical Ports are shown. DVB-S2 or DVB-S can be used in the downlink.
        MPEG can be used as well instead of ATM Logical Ports.

                                   FIGURE 3: Example stacking
     
        As can be seen from this example, the dvbRcsMacLayer interface is
        layered on top of the downstream and upstream interfaces, and the
        upstream interface is layered on top of upstream ATM logical links.
        In this example, the assignment of index values could be as follows:
     
              ifIndex       ifType                     Description
     
                 2    dvbRcsMacLayer (239)          DVB-RCS MAC Layer
                 3    dvbRcsTdma (240)              DVB-RCS TDMA Upstream
                 4    dvbTdm(241)                   DVB-RCS TDM Downstream
                 5    atm-logical(80)               ATM Logical Port
                 6    atm-logical(80)              ATM Logical Port
     
        The corresponding ifStack entries would then be as shown on Figure 4:
                      +--------------------+-------------------+
                      | IfStackHigherLayer | ifStackLowerLayer |

     3.4.  MIB groups description
     
     3.4.1.  rcstSystem
     
        The MIB objects in this group gather some basic information that
        would allow anyone to trace the history - the life - of the RCST as
        well as to get a complete description of its constitution on the
        component point of view, including the SatLabs options/features
        support statement. Many of the parameters will be defined at
        installation.
     
     
        This group contains description parameters related to the RCST type
        (ODU type) and location. These parameters are believed to stay
        unchanged once it has been defined during installation. Modification
        of hardware equipment, maintenance operations and geographical re-
        location may require an update of those MIB objects. They are. Note
        that rcstSystem.systemLocation object gives the location of the ODU
        antenna, which is needed for network operation, while the
        system.sysLocation (MIB-II SNMP OID) provides the location of the IDU
        unit, which can not be used for the same purpose.
     
     
     3.4.2.  rcstNetwork
     
        This group contains all the MIB objects related to network
        parameters.

        In this subgroup, two objects have been defined in order to
        differentiate between control and user traffic and associate them
        with a physical interface. Both rcstNetwork.networkLanIpAddress
        (Traffic) and rcstNetwork.networkOamIpAddress (OAM) provide the value
        of the IP address of, respectively, the user traffic and the control
        and management traffic.
     
     3.4.3.  rcstInstall
     
        This group contains all the information related to the RCST
        installation and commissioning. Many parameters are believed to stay
        unchanged once it has been defined during installation. Modification
        of hardware equipment, maintenance operations and geographical re-
        location may require an update of those MIB objects.
     
     3.4.4.  rcstQos
     
        This group contains objects to configure the Quality of Service (QoS)
        of the RCST by the NCC.
     
        The pktClass table defines the packet classification for IP layer 3
        classifications. Each pktClass entry is mapped to a phbEntry in the
        phbMappingTable.
     
        The phbMappingTable makes the relation between a packet
        classification entry, a Per-Hop Behavior (PHB) identifier and a
        Request class entry.
     
     
        The requestClassTable defines all the layer 2 DVB-RCS QoS parameters.
     
     3.4.5.  rcstControl
     
        This MIB group contains objects a network manager can use to invoke
        actions and tests supported by the RCST agent and to retrieve the
        action/test results.
     
     3.4.6.  rcstState
     
        This MIB group describes the fault state, software versions and
        configuration file versions of the RCST.
     
     3.4.7.  fwdLink (fwdConfig and fwdStatus groups)

     Internet-Draft               DVB-RCS MIB                      July 2008
     
     
        This MIB group contains parameters that enable the NCC to have access
        to data about the forward link.
     
        Configuration information is kept into the fwdLink.fwdConfig
        subgroup. Status information is kept into the fwdLink.fwdStatus
        subgroup.
     
     
        The information of the fwdLink.fwdConfig.fwdStartTable are used for
        the first time the RCST tries to acquire the forward link. All these
        objects values are aligned with the Satellite Delivery System
        Descriptor in the Network Information Table (NIT) table [ETSI-SI].
        The objects in the fwdLink.fwdConfig.fwdStatusTable are aligned with
        the satellite forward path descriptor form the RCS Map Table (RMT)
        [ETSI-RCS] and with the Physical Layer (PL) Header [ETSI-DVBS2],
        which specified the MODCOD (modulation and FEC rate) and the Type
        (frame length short of long and the presence/absence of pilots).
     
     
     3.4.8.  rtnLink (rtnConfig and rtnStatus groups)
     
        This MIB group contains parameters that enable the NCC to have access
        to data about the return link.
     
        Configuration information is kept into the rtnLink.rtnConfig
        subgroup. Status information is kept into the rtnLink.rtnStatus
        subgroup.
        The RCST is only able to deal with one return link at a time. Hence,
        there is no need to define a table to collect the different SNMP
        objects, as it is done for the forward.

     5. Security Considerations
     
        Some of the readable objects in this MIB module (i.e., objects with a
        MAX-ACCESS other than not-accessible) may be considered sensitive or
        vulnerable in some network environments.
     
     
        SNMP versions prior to SNMPv3 did not include adequate security. Even
        if the network itself is secure (for example by using IPsec), even
        then, there is no control as to who on the secure network is allowed
        to access and GET/SET (read/change/create/delete) the objects in this
        MIB module.
     
        It is RECOMMENDED that implementers consider the security features
        provided by the SNMPv3 framework (see [RFC3410], section 8),
        including full support for the SNMPv3 cryptographic mechanisms (for
        authentication and privacy).
     
        Further, deployment of SNMP versions prior to SNMPv3 is NOT
        RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
        enable cryptographic security.  It is then a customer/operator
        responsibility to ensure that the SNMP entity giving access to an

        instance of this MIB module, is properly configured to give access to
        the objects only to those principals (users) that have legitimate
        rights to indeed GET or SET (change/create/delete) them.
