Fair buffer credit distribution flow control

摘要

A data transfer management method is provided for transferring data between nodes of a multi-node communication system. The method provides target nodes with fair opportunity to transfer data to originator nodes in the communication system. The originator node initiates data transfer by establishing a connection with one or more target nodes. The originator node signals target nodes to transfer data by generating and transmitting credit tokens over the network. Before a target node can transfer data to the originator node, it must receive and absorb at least one credit token from the originator. All credit tokens transmitted by the originator node and not absorbed by target nodes return back to the originator node. Each target node is provided with buffer credit tokens up to its quota in a rotating manner.
