DISTRIBUTED MULTI-LINK PROCEDURE CONTROL SYSTEM

摘要

PURPOSE:To improve the processing capability by allowing a communication control processing unit to autonomously implement the provision of a multi-link sequence number to transmission data and the allocation of the transmission data to the communication control processor. CONSTITUTION:A host system 1 gives a sequence number representing a storage position of a transmission event to a control processor 31 and when the processor 31 itself is able to send data, the unit 31 adds 1 to the number and informs a device 32 of the result via a link 8. Simultaneously, the storage event is read from the number and a sequence number is added and the data are sent via a logic channel 71. The device 32 receiving the number adds '1' to the number similarly to the case with the processor 31 and informs a device 33 of the result and reads the transmission event and sends the result to a channel 72. A receiver side writes data to the storage location of a sequence number. A multi-link procedure control function is provided distributingly to the control processor in this way to improve the processing capability.
