Abstract: In an approach to an overlay network capabilities exchange for reserving high priority handling of packets, a computing device creates a transport protocol port map that correlates one or more inner protocols with one or more outer transport protocol port numbers. The computing device creates a priority bit re-map table that correlates one or more outer transport protocol port numbers with one or more levels of priority. The computing device then receives a packet having an associated protocol and an associated port number, and determines, based on the associated protocol and the associated port number, that the packet requires a level of priority of the one or more levels of priority that guarantees loss-less delivery of the packet.

Abstract: A method for overlay network capabilities exchange for reserving high priority handling of packets, for example, FCoE and other sensitive packets in an overlay network is achieved by determining a transport protocol port map, wherein the port map creates a correlation between one or more inner protocols and one or more outer transport protocol port numbers. The method includes determining a priority bit re-map table, wherein the priority bit re-map table creates a correlation between one or more outer transport protocol port numbers and one or more levels of priority. A combined table, may be determined wherein the combined table creates a correlation between one or more inner packet protocols, one or more outer transport protocol port numbers, and one or more levels of priority. The combined table is advertised to the other computing devices in a network and connected to the network.

Abstract: In one embodiment, a system includes processor; and logic integrated with and/or executable by the processor, the logic being adapted to: assign a VLAN type to each of a plurality of VLANs of an architecture; generate a VLAN list type-length-value (vTLV) message; and transmit information to resources based at least in part on the vTLV message, wherein the resources comprise at least one virtual switch and one or more of: at least one physical switch; at least one virtual port; at least one physical port; at least one virtual machine; at least one converged network adapter (CNA); and at least one fiber channel forwarder (FCF).
