Abstract
In general, techniques are described for mapping WAN conditions to appropriate back-pressure mechanisms at the WAN edges to improve the performance of delay and/or loss-sensitive applications. In one example, a system includes a wide area network having a provider edge (PE) router to establish a Fiber Channel over Ethernet (FCoE) pseudowire over the wide area network. A Lossless Ethernet network attaches, by an attachment circuit, to the FCoE pseudowire at the PE router. A Fiber Channel Fabric connects to the Lossless Ethernet network and to a storage device that provides data for transmission over the wide area network by the FCoE pseudowire. The PE router detects a defect in the FCoE pseudowire and, in response to detecting the defect in FCoE pseudowire, injects an FCoE flow control extension into the Lossless Ethernet network by the attachment circuit.
