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

2.2. Glossary

   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.

Internet-Draft               DVB-RCS MIB                September 2008


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.

2.2.18. Channel ID

   Each Request Class is identified by a unique Channel_ID in the
   communication between the RCST and the NCC.

Internet-Draft               DVB-RCS MIB                September 2008


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 optional feature is defined that allows their configuration
   at the RCST level in addition to configuration per RC. This feature
   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.

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.

   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.

   This is another name for a DVB-RCS based satellite network.





3. MIB Module overview

   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   |
                    +------------+---------------------------+
                    |dvbrcsMib   |{ mib-2 transmission 239 } |
                    +------------+---------------------------+

                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 SatLabs defined capabilities, 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:
   rcst, fwdLink and rtnLink.

   The rcst group covers management related to the RCST equipment. It is
   structured into six groups:

   o  rcstSystem

Internet-Draft               DVB-RCS MIB                September 2008


   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. The implementer is referred to the Interfaces MIB
   document in order 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            |

   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  dvRcsTdma: DVB-RCS TDMA that counts either ATM Adaptation Layer 5
      (AAL5) or MPE traffic, as applicable for a specific configuration

   The ifStackTable [RFC2863] MUST be implemented to identify the
   relationships among sub-interfaces.

   The following example is a 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.

   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:

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.

Internet-Draft               DVB-RCS MIB                September 2008


   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)

   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.



6. IANA Considerations

   This document includes no request to IANA. The transmission and
   ifType numbers described in Section 3 have already been assigned
   under the smi-numbers registry.
