Abstract: PURPOSE: To maintain the load balance of a message communication processing processor (MHP) by almost equally re-allocating plural message processing selection codes (MHSC) assigned to a defective MHP to each available MHP when any MHP breaks down. CONSTITUTION: When failure is generated in the node (interrupted point) of an MHP or the related link (signal line) of the MHP, the number of the active MHP is number-changed to the virtual number (virtual number, VMHP) of the MHP, and a take-over procedure is started based on the quotient of MHSC /N-i. For example, a signal message having a quotient 0 is path-designated to a VMHP#0, a signal message having a quotient 1 is path-designated to a VMHP#1, a signal message having a quotient (j) is path-designated to a VMHP#, and a signal message having a quotient (N-i-1) is path-designated to a VMHP#(N-i-1). In this case, when the number of the available MHP is equal to (N-i), and the quotient is larger than (N-i), this quotient is changed to (N-i), and the path designation of the message is executed.
