Title : The Pseudowire (PW) & Virtual Circuit Connectivity Verification (VCCV) Implementation Survey Results

Abstract:
Most pseudowire Emulation Edge-to-Edge (PWE3) encapsulations mandate
the use of the Control Word (CW) to carry information essential to
the emulation, to inhibit Equal-Cost Multipath (ECMP) behavior, and
to discriminate Operations, Administration, and Maintenance (OAM)
from Pseudowire (PW) packets. However, some encapsulations treat the
Control Word as optional. As a result, implementations of the CW,
for encapsulations for which it is optional, vary by equipment
manufacturer, equipment model and service provider network.
Similarly, Virtual Circuit Connectivity Verification (VCCV) supports
three Control Channel (CC) types and multiple Connectivity
Verification (CV) Types. This flexibility has led to reports of
interoperability issues within deployed networks and associated
drafts to attempt to remedy the situation. This survey of the PW/
VCCV user community was conducted to determine implementation trends.
The survey and results is presented herein.
