Abstract
A method and a device for modifying and forwarding a message in a data communication network are described. The method includes: description information of a message head is extracted as message descriptor information, and message fragments except the message descriptor information are stored; a pre-stored message modification description table is searched for modification parameters used for a message modification according to the message descriptor information; a needed message modification action is determined according to the obtained modification parameters, and the message fragments with a requirement of modification are modified in groups according to the types of actions; and the message fragments are distributed and reassembled according to port numbers, the message fragments are re-spliced into a complete message, and the message is sent to an external interface in time sequence. By modifying a pre-stored message modification description table through an external interface to add, alter or delete message modification parameters, the method and the device provided herein meet the demands for different kinds of services, greatly decrease the workload of design and reduce ma…
