OVERLAY CAPABILITIES EXCHANGE USING DCBX

摘要

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.

主权项

1. A method for overlay network capabilities exchange for reserving high priority handling for packets, the method comprising:
a computing device 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 computing device 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; the computing device determining a combined table, 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; and the computing device advertising the combined table to other computing devices in a network and connected to the network.
