Congestion profiling of computer network devices

摘要

A method may include transmitting data frames from a reaction point of a source device. The method may also include receiving, at the reaction point, congestion notification messages corresponding to the transmitted data frames and containing congestion feedback data regarding a particular network switching device and an identifier of the particular network switching device. The method may also include modifying a congestion profile for the particular network switching device by correlating the identifier of the particular network switching device to a profile entry, and updating the profile entry with the congestion feedback data.

1. A computer implemented method for generating congestion profiles for network switching devices, comprising:
transmitting data frames from a reaction point of a source device; receiving, at the reaction point, congestion notification messages corresponding to the transmitted data frames, each congestion notification message including congestion feedback data regarding a particular network switching device and an identifier of the particular network switching device; and modifying a congestion profile for the particular network switching device by:
correlating the identifier of the particular network switching device to a profile entry in a congestion point data sub-table,updating the profile entry with the congestion feedback data and a timestamp in response to a determination that the profile entry in the congestion point data sub-table exists, andcreating a new profile entry in the congestion point data sub-table, the new profile entry including the congestion feedback data and a timestamp, in response to a determination that the profile entry does not already exist in the congestion point data sub-table.
