2 Introduction
This document describes a model for managing encapsulated SONET Time
Division Multiplexed (TDM) digital signals for transmission over a
Packet Switched Network (PSN).
This document is closely related to [CEP], which describes the
technology to encapsulate TDM signals and provide the Circuit
Emulation Service over a Packet Switched Network (PSN). This document
is also related to [TRANS and ENCAP], describing the transport and
encapsulation of Layer 2 circuits over MPLS, respectively. NOTE: the
CEP encapsulation can be used over non-MPLS PSNs as well as MPLS
PSNs.
The model for CEP management is a MIB. The CEP MIB described in this
document works closely with the MIBs described in [PWMIB] and the
textual conventions defined in [PWTC]. In the spirit of the [IFMIB],
a CEP connection will be a virtual connection (VC), and will
therefore not be represented in the ifTable.
CEP is currently specified to carry "structured" SONET paths. Meaning
that each SONET path within the section/line can be processed
separately. The SONET section/line interface stack is modeled within
[SONETMIB]. The CEP MIB will reference SONET paths as modeled within
[SONETMIB].
Comments should be made directly to PWE3 at pwe3@ietf.org.
This memo does not, in its draft form, specify a standard for the
Internet community.

this document are to be interpreted as described in RFC-2119
[BCP14].
3 Terminology
CEP terminology comes from the CEP draft that describes a mechanism
for transporting SONET Time Division Multiplexed (TDM) digital
signals over a packet-oriented network. The mechanism for structured
(as outlined in the CEP draft) terminates the SONET section and line
overhead and then breaks the SONET path's Synchronous Payload
Envelope (SPE) into fragments for transmission over a PSN. A CEP
header is appended at the beginning of each fragment to provide
information regarding where the SPE begins within the packet stream,
a sequence number, and pointer adjustment information (see [CEP]).
"NSP" (Native Service Processing) refers to the method of adapting a
"native" service such that it can be presented to the PW (Pseudo-
Wire) for transmission across the packet core. In this case, the
native protocol is SONET/SDH. See [LAYER].
"Outbound" references the traffic direction where a SONET path's
payload (SPE) is received, adapted to packet, assigned a VC label,
and sent into the PSN.
Conversely, "inbound" is the direction where packets are received
from the PSN, packet payloads are reassembled back into an SPE, and
inserted as a SONET path into the SONET section and line.
Since A SONET path is bi-directional and symmetrical, it uses the
same SONET time-slot, SONET width, packet size. Inbound and outbound
VC labels may differ.
CEP will normally transmit into an originating "head" end of a PSN's
tunnel, and receive from a terminating "tail" end a PSN's tunnel. In
the case of an MPLS PSN, a CEP connection typically uses a VC
(virtual connection) Label within a Tunnel Label [TRANS]. Multiple
CEP VCs each with a unique VC Label and similar traffic engineering
requirements can share the same PSN tunnel. For MPLS PSNs, the Tunnel
Label is known as the "outer" Label, while the VC Label is known as
the "inner" Label. An exception to this is with adjacent MPLS LSRs.
In this case, there is an option for CEP VCs to connect directly
without an outer Label.
4 The SNMP Management Framework
The SNMP Management Framework presently consists of five major
components:
o An overall architecture, described in RFC 2571 [RFC2571].
Danenberg et al Expires November 2002 3
Internet Draft PW CEP MIB August 2002
o Mechanisms for describing and naming objects and events for the
purpose of management. The first version of this Structure of
Management Information (SMI) is called SMIv1 and described in STD 16,
RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC 1215
[RFC1215]. The second version, called SMIv2, is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
o Message protocols for transferring management information. The
first version of the SNMP message protocol is called SNMPv1 and
described in STD 15, RFC 1157 [RFC1157]. A second version of the
SNMP message protocol, which is not an Internet standards track
protocol, is called SNMPv2c and described in RFC 1901 [RFC1901] and
RFC 1906 [RFC1906]. The third version of the message protocol is
called SNMPv3 and described in RFC 1906 [RFC1906], RFC 2572 [RFC2572]
and RFC 2574 [RFC2574].
o Protocol operations for accessing management information. The
first set of protocol operations and associated PDU formats is
described in STD 15, RFC 1157 [RFC1157]. A second set of protocol
operations and associated PDU formats is described in RFC 1905
[RFC1905].
o A set of fundamental applications described in RFC 2573
[RFC2573] and the view-based access control mechanism described in
RFC 2575 [RFC2575].
A more detailed introduction to the current SNMP Management Framework
can be found in RFC 2570 [RFC2570]. Managed objects are accessed via
a virtual information store, termed the Management Information Base
or MIB. Objects in the MIB are defined using the mechanisms defined
in the SMI. This memo specifies a MIB module that is compliant to the
SMIv2. A MIB conforming to the SMIv1 can be produced through the
appropriate translations. The resulting translated MIB must be
semantically equivalent, except where objects or events are omitted
because no translation is possible (use of Counter64). Some machine
readable information in SMIv2 will be converted into textual
descriptions in SMIv1 during the translation process. However, this
loss of machine readable information is not considered to change the
semantics of the MIB.
4.1 Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object type
together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we
often use a textual string, termed the descriptor, to also refer to
the object type.

5 Feature Checklist
This MIB is designed to satisfy the following requirements and
constraints:
- Fits within the architecture defined [PWMIB].
- The MIB supports point-to-point CEP connections. Point-to-
multipoint connections are for future study.
- The MIB configures the connection: timeslots, packet length, error
actions, and many other CEP objects.
- The MIB reports: packet counts, error counts, and many other status
objects.
6 CEP MIB usage
6.1 Summary of CEP MIB
- The CEP VC Table (pwVcCepTable) contains the SONET Path ifIndex,
SONET Path Time slot, the pwVcCepCfgTable index, config error
indications, and various status indications.
- The CEP VC Configuration Parameter Table (pwVcCepCfgTable) has
objects for CEP VC configuration. In situations where sets of config
objects are common amongst more than 1 CEP VC, 1 entry here may be
referenced by many pwVcCepTable entries.
- The CEP Performance Current Table (pwVcCemPerfCurrentTable)
contains CEP stats for the current 15-minute period.
- The CEP Performance Interval Table (pwVcCemPerfIntervalTable) is
similar to the pwVcCemPerfCurrentTable. It contains historical
intervals (usually 96 15-minute entries to cover a 24 hour period).
Note: the performance interval statistics are supported by CEP due to
the very function of CEP - that is, processing SONET. See [SONETMIB].
- The CEP Performance Total Table (pwVcCepPerfTotalTable) is similar
to the pwVcCemPerfCurrentTable. It contains statistics accumulated
since the CEP VC was first established.
- The Conformance Config Table (pwVcCepConformanceCfgTable) allows
the vendor to specify the extent to which certain objects are
supported (or not).
Danenberg et al Expires November 2002 5
Internet Draft PW CEP MIB August 2002
6.2 CEP configuration Step by Step
Configuring a CEP VC involves the following steps.
First create an entry in the pwVcTable and configure the PSN tunnels:
- Follow steps as defined in [PWMIB].
Configure the SONET Path parameters :
- Set the SONET path width in the sonetPathCurrentTable [SONETMIB].
- Set the SONET path index and the SONET path starting time slot in
the pwVcCepTable.
NOTE: The agent will have created an entry in the pwVcCepTable based
on the entry created in the pwVcTable.
Configure the CEP VC:
- If necessary, create an entry in the pwVcCepCfgTable (a suitable
entry may already exist). Set packet length, etc.
- Set the index of this pwVcCepCfgTable entry in the pwVcCepTable.
Observe the CEP VC:
- Once a CEP VC is operational, the pwVcCepPerfCurrentTable,
pwVcCepPerfIntervalTable, and pwVcCepPerfTotalTable are used to
monitor the various counts, indicators, and conditions of the VC.
Conforming to the CEP MIB objects:
- The pwVcCepConformanceCfgTable is used to state True/False whether
certain objects are supported. An ASCII string object is available
with every True/False object as a means to explain the extent of
'true' support, or perhaps explain why the 'false' was set.

Internet Draft PW CEP MIB August 2002
7 Example of CEP Setup
In this section we provide an example of using the MIB objects
described in section 8 to set up a CEP VC (width of 3 STSs, starting
at time slot 1). While this example is not meant to illustrate every
permutation of the MIB, it is intended as an aid to understanding
some of the key concepts. It is meant to be read after going through
the MIB itself. See [PWMIB] for an example of setting up PSN Tunnels.
First configure the SONET path width, starting time-slot, and
associated CEP VC. In this case, an STS-3c starts at SONET time slot
1 (and is distributed normally within the SONET frame). In the
following example, the ifIndex for the sonetPathCurrentEntry is 23,
while the pwVcCepCfgTable index is 9.
In [SONETMIB] sonetPathCurrentEntry (ifIndex = 23) :
{
sonetPathCurrentWidth = 3,
sonetPathCurrentStatus
...
...
}
Create an entry in the pwVcCepCfgTable (index = 9) :
{
pwVcCepCfgNormalPktLength = 500 -- payload bytes
pwVcCepCfgMinPktLength = 0 -- no minimum
pwVcCepCfgPktReorder = FALSE
pwVcCepCfgEnableDBA = ais
pwVcCepCfgJtrBfrDepth = 500 -- micro-seconds
pwVcCepCfgConsecPktsInsync = 2 -- Exit LOPS state
pwVcCepCfgConsecMissingOutSync = 10 -- Enter LOPS state
pwVcCepCfgPktErrorPlayOutValue = playAllOnes
pwVcCepCfgMissingPktsToSes = 3 -- packets,
pwVcCepCfgSesToUas = 2 -- seconds,
pwVcCepCfgSecsToExitUas = 10 -- seconds,
pwVcCepCfgRowStatus = createAndGo
}
Check that there are no error bits set in pwVcCepConfigError.
Danenberg et al Expires November 2002 7
Internet Draft PW CEP MIB August 2002
In PW-MIB: Get a new index and create a new pwVcTable entry using
pwVcIndexNext (here, the VC index = 83) and pwVcRowStatus. In this
new entry, set pwVcType to 'cep'. This should create a new entry in
the pwVcCepTable. Set up and the SONET path ifIndex, SONET path time
slot, and Cfg Table indexes within this new pwVcCep table entry:
{
pwVcCepSonetIfIndex = 23 -- Index of associated entry
-- in sonetPathCurrent table.
pwVcCepSonetTimeSlot = 1 -- Starting time slot.
pwVcCepCfgIndex = 9 -- Index of associated entry
-- in pwVcCepCfg table (above).
}
Check that there are no error bits set in pwVcCepSonetConfigError.

"Definitions:
missingPkt - While playing out a sequence of packets,
a packet(s) was determined to be missing based on
a gap in the CEP sequence number. Note: If the imple-
mentation supports packet re-ordering, detecting gaps
should not take place as packets arrive, only as they
are played out - this gives time for mis-ordered packets
to arrive late.
Danenberg et al Expires November 2002 15
Internet Draft PW CEP MIB August 2002
ooRngDropped - Packet(s) arrives that is outside the
range of the jitter buffer. This may be because the
jitter buffer is full, or the sequence number addresses
a buffer outside the current jitter buffer range, or
addresses an already occupied buffer within range.
Whether or not packet re-ordering is supported by the
implementation, this indication MUST be supported.
jtrBfrUnder - The jitter buffer underflowed due to
not enough packets arriving as packets were being
played out.
pktBadLength - Non-bandwidth-saving packet arrives
larger or smaller than pwVcCepCfgNormalPktLength.
lops - Loss Of Packet Sync. See draft-ietf-pwe3-sonet.
cepRdi - Circuit Emulation over Packet Remote
Defect Indication. Generated by the remote CEP
de-packetizer when detecting LOPS. Note: not gen-
erated by the remote SONET function. See draft-ietf-
pwe3-sonet.
cepAis - Remote CEP packetizer has detected AIS
on its incoming SONET stream. See draft-ietf-pwe3-
sonet. Note: cepAis MUST NOT (in itself) cause a CEP
down notification. This would be a layer violation.
Note: currently there is no hierarchy of CEP defects.
Note: the algorithm used to capture these indications
is implementation specific."
