Interprocessor switching network
First Claim
1. Communication circuitry for a plurality of processors, comprising:
- first transfer circuitry responsive to program code and capable of transferring interprocessor communications between a predetermined first set of said plurality of processors,second transfer circuitry responsive to program code and capable of transferring interprocessor communications between said predetermined first set of said plurality of processors and at least a second set of said plurality of processors and operable to allow simultaneous and distinct communications among said plurality of processors, andcontrol circuit for sensing changes in at least one of said plurality of processors and for responding to said sensed changes by dynamically modifying said program code for at least one of said first and second transfer circuitry.

Abstract
A message transport network (10) is provided for high speed switching between processing elements (72, 80). Clusters of low speed processing elements (72) may be connected to the message transport network (10) through a transport node controller (78). The transport node controller (78) and the high speed processors (80) are connected to the gateways (82). A pair of gateways (82) may be connected through a transport interchange node (106) to allow communication between processors (72, 80) associated with the gateways (82). A transport interchange supervisor (98) maintains a record of the status of each gateway (82) and generates commands to form connection between gateways (82) in the transport interchange node (106). A maintenance controller (102) and system maintenance processor (76) oversee the validity of the data being passed through the system on paths independent of the data transfer paths. The message transport network (10) may be used in variety of applications, such as a telephony switch (11), a signaling transfer point system (21) or a fault tolerant minicomputer (49).
