The Pseudowire and Virtual Circuit Connectivity Verification Implementation Survey Results
RFC 7079, “The Pseudowire and Virtual Circuit Connectivity Verification Implementation Survey Results”, is an Informational document published in November 2013 by N. Del Regno, A. Malis. The canonical text is published by the RFC Editor.
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.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
