Sdp Statistics For Vll Services; Sap Encapsulations And Pseudowire Types - Alcatel-Lucent 7705 Service Manual

VLL Service Considerations

SDP Statistics for VLL Services

The 7705 SAR supports local CLI-based and SNMP-based statistics collection for each VC
used in the SDPs. This allows for traffic management of tunnel usage by the different
services and, with aggregation, the total tunnel usage.

SAP Encapsulations and Pseudowire Types

The section describes encapsulations and PW types for the following VLL services:
Apipe
ATM VLLs can be configured with both endpoints (SAPs) on the same router or with the
two endpoints on different routers. In the latter case, Pseudowire Emulation Edge-to-Edge
(PWE3) signaling can be used to establish a pseudowire between the devices, allowing ATM
traffic to be tunneled through an MPLS or IP network.
As an alternative to signaled pseudowires, manual configuration of pseudowires is also
supported.
The Apipe service supports both VP and VC connections, which are identified by specifying
the
supported (see
is always 1.
The supported PW service types are 0x0009 (for ATM N-to-1 VCC cell mode) and 0x000A
(for ATM N-to-1 VPC cell mode), as defined in RFC 4446.
Cpipe
Cpipe service supports CESoPSN and SAToP encapsulation over MPLS or GRE tunnels to
connect to the far-end circuit. Cpipes support SAP-to-SAP and SAP-to-spoke SDP binding
with a default service MTU of 1514 bytes.
The supported PW service types are 0x0011 (SAToP E1), 0x0012 (SAToP T1), 0x0015
(CESoPSN basic mode), and 0x0017 (CESoPSN TDM with CAS).
