Encapsulation Methods for Transport of
Fibre Channel Traffic over MPLS Networks
Abstract
A Fibre Channel pseudowire (PW) is used to carry Fibre Channel
traffic over an MPLS network. This enables service providers to take
advantage of MPLS to offer "emulated" Fibre Channel services. This
document specifies the encapsulation of Fibre Channel traffic within
a pseudowire. It also specifies the common procedures for using a PW
to provide a Fibre Channel service.

RFC 6307 FC Encapsulation April 2012
1. Introduction
Fibre Channel (FC) is a high-speed communications technology, used
primarily for Storage Area Networks (SANs). Within a single site
(e.g., data center), an FC-based SAN connects servers to storage
systems, and FC can be extended across sites. When FC is extended
across multiple sites, the most common usage is storage replication
