Embodiment Construction

[0033] The technical solution of the present invention will be further described in more detail below in conjunction with the drawings and specific embodiments.

[0034] As shown in Figure 2, it is a schematic diagram of the structure of the communication system of the present invention. The entire communication system 200 includes: a transceiver thread group 20 and its service interface 201, a dynamically allocated link pool 30, a link state machine 40, and a message interface 50 modules. The communication system 200 has a dynamically allocated connection pool, asynchronous IO Multiplexing (input and output multiplexing), Link (link) state machine, and pre-created multi-transceiving thread concurrent processing.

[0035] The transceiver thread group 20 is responsible for receiving and sending data messages transmitted on the link, and provides communication services to the external network element 60 through the service interface 201, and can also actively initiate service reques...

Abstract

The invention discloses a communication system based on TCP parallel multilink and a method thereof. The system comprises a receiving / transmitting thread group, a dynamic distribution connection cell, a link state machine and a message interface. The receiving / transmitting thread group is used for completing data reception and transmission of the link, and changing the current working state of the link state machine according to the data reception and transmission state; and the dynamic distribution connection cell is used for managing the connection constructed between a communication system and an external net element. When transmitting or receiving the link data, the receiving / transmitting thread group constructs corresponding link by calling the service of the dynamic distribution connection cell and register the call-back service of corresponding event message through the link state machine; and the link state machine acquires corresponding link event according to the initiation and reception status of the request of the external net element link and achieves the transmission or reception of the link data through the call-back service of the receiving / transmitting thread group. The invention can improve the parallel link number of the system, and improve the processing efficiency and realtime performance of the system during high parallel link and large data transmission.

Description

Technical field [0001] The invention relates to the field of telecommunication data network communication, in particular to a system and method for concurrent multiple TCP links in a data communication system. Background technique [0002] In current communication systems based on data networks, a network element can usually be divided into a communication layer and a service layer. The communication layer is responsible for the access and message sending and receiving of external network elements, and the business layer completes the process processing related to business logic. As a carrier-grade network communication device, it must have efficient and robust communication layer facilities, and it can even be extended to a communication interface machine to achieve network element access. In addition, high concurrency and multiple connections are also necessary features of carrier-grade network communication equipment. At present, the common implementation of the communication ...
