| 摘 要： | 网控中心（ＮｅｔｗｏｒｋＣｏｎｔｒｏｌＣｅｎｔｅｒ）是ＶＳＡＴ卫星通信系统的核心。本文讨论网控中心的设计与实现。论文首先简要介绍了一种容错的网控中心结构模型，该模型采用的主要策略是冗余备份。然后，进一步讨论了网控中心的可靠性设计。最后，介绍了一种基于多线程的网控中心的实现。通过利用多线程和多级容错措施等方法，我们实现的网控中心具有可靠性好，高性能，容易使用等特点。

| Abstract: | NCC(Network Control Center) is the core of VSAT satellite communications system.This paper presents the design and implementation of an NCC in a VSAT satellite communication system.Firstly,a fault tolerance NCC architecture which mainly makes use of redundant backup is presented.Then,we mainly address the design of reliability in details.Lastly,the implementation based on multithread is addressed.The NCC that we implemented has following features:high reliability,high efficiency,ease to use,which are achieved by many techniques such as multithreading,multi level fault tolerance techniques,etc. |
