Abstract

PURPOSE:To drive an extended communication control processor without input of a processor type and an operation start instruction from an external device. CONSTITUTION:A program operated on a communication control processor is stored in advance on a hard disk 12 by each communication control processor type. A processor management equipment 11 manages a communication control processor in a packet exchange 10 totally and a program in the hard disk is transferred to the communication control processor. An extended communication control processor 20 sends a processor type from a processor type signal transmission circuit 21 to the processor management equipment 11 via a system bus 13 at the start of operation. The processor management equipment 11 transfers the program corresponding to the extended communication processor 20 from the hard disk 12 and the operation start is instructed.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for adding communication control processors to a distributed control type packet switching equipment which is composed of a plurality of communication control processors.

0002

[Prior Art] Conventionally, this type of processor expansion method was
After completing the addition of a hardware package, instructions were given from a system console connected to the packet switch to transfer the program to the added processor for operation.

0003

[Problems to be Solved by the Invention] In the conventional communication control processor expansion method described above, the expansion processor is operated according to instructions from the system console connected to the packet switch. There was a problem that the vehicle would not start operating.

SUMMARY OF THE INVENTION An object of the present invention is to provide a communication control processor expansion method that allows the expansion processor to be operated without externally instructing the processor type and operation start.

[0005]

[Means for Solving the Problems] The communication control processor expansion method of the present invention is a communication control processor expansion method for a distributed control processor type packet switching equipment in which a plurality of types of communication control processors are connected to a system bus. , a hard disk in which a program running on a communication control processor is stored in advance for each type of communication control processor in the packet switch; and a communication control processor in the packet switch are collectively managed; a processor management device having a means for transferring a program to the communication control processor to be added; and a means for transmitting the processor type to the communication control processor to be added at the time of starting operation; The processor management device transmits the loaded signal to the processor management device, and upon receiving the signal, the processor management device transfers a program corresponding to this processor type from the hard disk to operate the added communication control processor. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of adding a communication control processor according to the present invention. A packet switch 10 includes a processor management device 11 that collectively manages communication control processors in the packet switch, and a communication control processor 11 that collectively manages communication control processors in the packet switch. It has a hard disk 12 that stores programs that run on the processor, and a system bus 13 to which a plurality of communication control processors can be connected. The expansion communication control processor 20 includes a processor type signal transmission circuit 21 for transmitting a processor type signal. The processor management device 11 is connected to a hard disk 12 and a system bus 13.

[0008] An additional communication control processor 20 is installed,
When the connector 14 is connected to the system bus 13,
The processor type signal transmission circuit 21 transmits the processor type signal to the processor management device 11 via the connection cable 22 and the system bus 13. The processor management device 11 that has received the processor type signal reads the program corresponding to this processor type from the hard disk 12, transfers it to the additional communication control processor 20, and then transmits an operation instruction.

In this embodiment, the instruction to start operation has been explained using an example in which the connection connector 14 is connected to the system bus, but it may also be done by turning on the power of the amplification processor or a combination of these, and the instruction method for starting operation is as follows. Not particularly limited.

0010

As explained above, the present invention transmits a processor type signal from the additional communication control processor when the additional communication control processor starts operating, and the processor management device that receives this signal downloads the corresponding program from the hard disk. By reading it out, transferring it to the additional communication control processor, and operating the additional communication control processor,
Particularly effective is the ability to operate additional processors without having to specify the processor type or start operation from the system console.
