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 ECMP behavior, and to discriminate OAM from
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.
