METHOD, SYSTEM AND NODE FOR BACKPRESSURE IN MULTISTAGE SWITCHING NETWORK

摘要

The present invention provides a backpressure method, system, and intermediate stage switching node of a multistage switching network and an intermediate stage switching node. The method includes: (i) the intermediate stage switching node receives a first backpressure information; and (ii) the intermediate stage switching node sends at least part of the first backpressure information to an upper stage switching node, wherein there is no response sent by the intermediate switching node to at least part of the first backpressure information.
