A stream-based communication framework for network control system

A common formalized definition of NCS data stream and a data stream communication protocol are presented in this paper. Design and implementation of a stream-based communication framework (SCF) based on NCS data stream concept are also described. SCF satisfies all kinds of NCS communication requirements, especially in the shared network supported multi-transmission protocols, such as Internet. As data stream communication protocol is taken as standard communication protocol in SCF, interactions of all components in NCS can be unified. It also supplies better fault tolerance, communication efficiency and flexibility. Proved by practice, SCF improves the development efficiency of NCS, and owns high expansibility and maintainability.
