Information interaction method of routing management module and protocol subsystem

An information interaction method of a routing management module and a protocol subsystem comprises the following steps of (1) establishing a routing deleting interface function and a routing adding interface function of the protocol subsystem, registering various service interfaces of the protocol subsystem and starting a guarding monitoring program of the protocol subsystem; (2) filling routing information which need to be deleted or added; (3) setting a routing deleting command and a routing adding command; (4) performing a public service interface of the routing information; (5) building a command massage and sending a routing command message to a ZSYS (Z System) module; and 6) receiving the routing command message which is sent from the protocol subsystem through the ZSYS module, determining a type of the routing command message, performing a routing deletion function of a gateway system when the routing command message is the routing deleting command, performing a routing update or adding function of the gateway system when the routing command message is the routing adding command and redistributing a command task to a backend of the guarding monitoring program of the protocol subsystem when the routing command message is a routing redistributing command through the ZSYS module.
