Abstract: A network node that forwards traffic of a converged network received from a source end node receives a second message addressed to the network node, but intended for the source end node. The second message includes at least a portion of a first message originated by the source end node and previously forwarded by the network node. The network node extracts from the first message a source identifier of the source end node in a first communication protocol and determines by reference to a data structure a destination address of the second message in a second communication protocol. The network node modifies the second message to include the destination address and forwards the second message toward the source end node in accordance with the destination address.

Abstract: Provided are computer program product, system, and method for determining whether a short or long message format is used to communicate zone information in a network. One large zone is implemented for end devices coupled to ports of data forwarders. A first formatted zoning distribution message is generated for the data forwarders identifying the data forwarder and ports on the data forwarders in the one large zone in response to determining that the data forwarder supports the short message format. A second formatted zoning distribution message is generated identifying the data forwarder, the ports on the data forwarders, and additional fields of information on the ports not included in the first formatted zoning distribution message in response to determining that the data forwarder does not support the short message format; and sending the generated first formatted or second formatted zoning distribution message to the data forwarder.

Abstract: Techniques are provided for detecting failure of switching elements of a distributed switch configured to forward Fiber Channel over Ethernet (FCoE) frames. Periodic discovery advertisement messages, which include a fabric name fieldm, are transmitted between a controlling Fiber Channel Forwarder (cFCF) and a FCoE data forwarder (FDF). The cFCF determines a FDF has failed out of the switch fabric based on a reserved value in the fabric name field of a received discovery advertisement message, such as a zero or null value, and de-instantiates virtual links with that FDF.

Abstract: Provided are a method, a system, and a computer program product in which a plurality of switches are maintained in a cascaded configuration. A switch relays a switch fabric internal link services (SW-ILS) to generate a pair of exchanges comprising a first exchange and a second exchange at the switch. In response to a termination of the first exchange of the pair of exchanges, the second exchange of the pair of exchanges is terminated.
