ABSTRACT:
A system for controlling traffic in a digital communication network to avoid data loss due to congestion utilizes an integrated credit-based and rate-based traffic control approach, and adjusts the rate at which data is transmitted from a source in accordance with feedback in the form of rate and credit adjustment information from a network reflecting the ability of the network to transmit data and the destination to receive data. In one embodiment, a source end system sends out resource management cells composed of various fields containing rate and credit information. The intermediate systems of the network and the destination end system update the corresponding fields according to their congestion status and send the resource management cells back to the source end system so that the source end system controls the data transmission accordingly. In a preferred embodiment, a source end system calculates an allowed cell rate from each of the fields in a resource management cell, and the minimum one among them is used to control data transmission.
