ABSTRACT:
Traffic information is accumulated and flow control information distributed in a packet switching system. Traffic information is collected in multiple elements, which forward in a coordinated fashion to collecting elements indications of congestion and other types of information. The collecting elements manipulate the received indications and generate flow control messages which are sent to individual sending components of the packet switching system. In one implementation, a switching element maintains for each destination a count of packets within itself which are addressed to the particular destination. An indication of a portion of this collected information is included in a packet header forwarded from each of the elements each packet time. Each of the elements are assigned a different offset, such that they send an indication of a different portion of their collected information, so a view of the traffic conditions and/or buffer occupancies within a packet switching system is efficiently produced.
