End to end flow control in a network

摘要

A network node (11-17) within a network includes a first receive buffer (24), first buffer management (22), a second receive buffer (27) and second buffer management (25). The first buffer management (22) performs link level credit based flow control for network packets that the first buffer management (22) places in the first receive buffer (24). The second buffer management (25) performs end-to-end credit based flow control for network packets that the second buffer management (25) receives from the first receive buffer (24) and processes before placing data in the second receive buffer (27).
