Problems solved by technology
Although the distributed communication platform adopts a distributed structure to disperse the pressure on the server, the server still runs on the platform and cannot achieve complete decentralization; the traditional communication platform uses the method of sending all dynamic data to the platform at a fixed time, although the application Common, but the communication speed is slow, the platform capacity is small, and the platform data flow is large, which seriously hinders the development of real-time and efficient distributed equipment

The invention provides a communication platform based on a TCP / IP protocol. The platform contains multiple computers provided with network cards. Each computer is provided with one or more nodes whichare mutually independent and have equal status. Each node is connected with the other nodes in a point-to-point communication manner. A first software program, parameter tables, first dictionaries and second dictionaries are also set in the computer. The first software program generates control information packets and data information packets, and carries out node registration, online managementand inter-node data interaction. The parameter tables contain multiple pieces of parameter data of the nodes. One node corresponds to one parameter table. Data receiving and sending management is carried out among the nodes through the parameter tables. The first dictionaries and the second dictionaries respectively contain IP address and port information of the nodes and all the other nodes. A new node can carry out registration to any online node for joining the platform. Communication connection with all online nodes is automatically realized after registration of the new node succeeds. Theinvention also discloses a communication method. The communication platform of the invention does not require a server, carries out data receiving and sending management through the parameter tables,and improves communication efficiency.
Description
technical field [0001] The invention relates to the field of computer technology, in particular to a communication platform based on the TCP / IP protocol. Background technique [0002] Network communication technology is the core of the data exchange of the entire distributed equipment. It is not only the basis for transmitting real-time control information, but also the key to comprehensive information management of the whole system. Network communication mainly studies the way of data transmission between multiple devices in the local area network and the accuracy, real-time and reliability of data. Although the distributed communication platform adopts a distributed structure to disperse the pressure on the server, the server still runs on the platform and cannot achieve complete decentralization; the traditional communication platform uses the method of sending all dynamic data to the platform at a fixed time, although the application Common, but the communication speed ...
