The present publication discusses how packets and buffers should be classified and then proposes a new classification scheme. The new scheme is compared against several well-known schemes. The discussions assume that flow control is performed in the hop-by-hop manner. Namely, every session is broken up into multiple pipes, one for each link. Each of these pipes is flow-controlled separately by a window mechanism. Each link has its own flow-control mechanism separately from other link flow control operation. This invention is used to reduce the following: heavy congestion at intermediate modes, store and forward buffer deadlocks, and unfair resource allocation. In a buffer class (BC) scheme, buffers and packets are divided into classes. A packet can be stored only in a buffer of its own class.
