Method and apparatus for accumulating and distributing data items within a packet switching system

摘要: Methods and apparatus are disclosed for accumulating distributing information in a packet switching system. For example, it is desirable certain systems to communicate the status of internal queues other port from an individual all ports (or at least those which communicating with port). The amount being sent typically very small, such as on order few bits or bytes. By then broadcasting collected flow control information, vast switch fabric resources (e.g., bandwidth) can be saved. In one implementation, destination “mailbox”) within includes memory accumulated. After period time based occurrence some event, accumulated distributed. This same mechanism may used distribute most any type signaling data external system).
