High Availability Connection Management via Software Bus and Mobile Agent in Network Management Environment

摘要

This paper analyzes the requirements of reliability connection in network management environment (NME). It points out the shortcomings of existed fault tolerant system and high availability (HA) system in NME. In order to address the connection reliability problem, new concept of HA connection is proposed. In order to assure the HA connection in NME, this paper proposes a provision of software bus theory which is composed of basic concept, link model, implementation model and network implementation model. Then, an implementation of software bus based on message mechanism and mobile agent supporting HA connection is discussed in detail. At last, performance of this system is discussed and evaluated.
