Abstract:
Methods and apparatus are provided for injecting Fiber Channel over Ethernet (FCoE) discovery packets, such as FCoE Initialization Protocol (FIP) or Data Center Bridge Exchange (DCBX) Protocol packets, by proxy or by spoofing into data center networks supporting FCoE in certain switchover, In-Service Software Upgrade (ISSU), and error scenarios. The transmission by proxy or by spoofing may occur at an intermediate FIP snooping bridge for communicating between FCoE devices. In this manner, the robustness of an FCoE path from one end of the data center network to another may be increased.
