摘要： 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.

摘要： Systems and methods to forward data frames are provided. A particular method may include receiving a data frame at a distributed virtual bridge. The distributed virtual bridge includes a first bridge element coupled to a first server computer and a second bridge element coupled to the first bridge element and to a second server computer. The distributed virtual bridge further includes a controlling bridge coupled to the first bridge element and to the second bridge element. The controlling bridge includes a global forwarding table. The data frame is forwarded from the first bridge element to the second bridge element of the distributed virtual bridge using address data associated with the data frame.

摘要： Techniques are provided for packet routing in a distributed network switch. The distributed network switch includes multiple switch modules operatively connected to one another, and each switch module includes multiple bridge elements and a management controller. In one embodiment, a shared interface routing (SIR) framework is provided that includes an analysis and bifurcation layer, at least one packet interface, and an analysis assist layer. A packet is received over a first logical network and via a physical port, the packet being destined for at least a first application executing on the management controller. The analysis assist layer analyzes the packet to determine a reason code to assign to the packet. The analysis and bifurcation layer then analyzes the packet based at least in part on the reason code.
