Abstract

A system and method for managing information transfers over a network through priority level feedback is provided. The feedback feature provides priority level feedback which informs a cell source of a typical priority level which is being accepted by the nodes of the connection rather than being discarded due to connection congestion. The worst-case network load information for a connection is determined by calculating a requisite cell priority necessary to allow cell acceptance at each of the intermediary network nodes on the connection. A record is maintained of the minimum requisite cell priority corresponding to the worst-case network load information for the connection. The worst-case network load information is provided to the cell source, where one of the priority levels is established for cells subsequently output from the cell source in response to the network load information.
