Abstract
A packet communication network is arranged so that a backpressure or feedback signal is sent from a receiving node to a node having packets to send to the receiving,node, selectively allowing only certain packets to be considered eligible for transmission. The backpressure is arranged to be lossless, and to avoid network deadlocks and livelocks. The transmission of a packet p from a sending node Xto a receiving node R, via a link l, is controlled by (a) sending from the receiving node Rto the upstream node Xa feedback value fthat assures that there will be room in the buffer in the receiving node Rto store packets subsequently received from the upstream node X; (b) assigning a priority level λto packets stored in the buffer of the receiving node R; and (c) transmitting from the sending node Xto the receiving node R, only those stored packets at Xwhose priority level λexceeds the feedback value freceived from the receiving node R.
