The Pseudowire (PW) and Virtual Circuit Connectivity Verification (VCCV)
Implementation Survey Results
Abstract
The IETF Pseudowire Emulation Edge-to-Edge (PWE3) working group has
defined many encapsulations of various layer 1 and layer 2 service-
specific PDUs and circuit data. In most of these encapsulations, use
of the Pseudowire (PW) Control Word is required. However, there are
several encapsulations for which the Control Word is optional, and
this optionality has been seen in practice to possibly introduce
interoperability concerns between multiple implementations of those
encapsulations. This survey of the Pseudowire / Virtual Circuit
Connectivity Verification (VCCV) user community was conducted to
determine implementation trends and the possibility of always
mandating the Control Word.
