| 摘 要： | 高可用性是对通信系统的主要要求之一，冗余设计是提高系统可用性的有效方法。通信系统的冗余设计包括设计高效、可靠的系统架构，系统及部件可靠性分析，冗余部件及冗余方式选择，全面、准确的告警机制设计，高速的切换互锁机制设计，高效的冗余数据同步方式设计等。冗余设计可以提高系统的可靠性，也提高了系统成本和系统复杂度，增加设计的难度，如何合理而有效地进行系统冗余设计，是值得研究的课题。

| Abstract: | High availability is one of the most important requirements on the communication system. Redundant design is an efficient way to improve system availability. Redundant design in communication system includes redundant architecture design, reliability calculation of the system and components, redundant components and structure choice, system monitor and switchover control and redundant data synchronization. Redundancy can enhance the system reliability,however, it will increase system cost and complexity, and time to design. It＇s valuable to pay more attention to how to design redundant system in a reasonable and highly efficient way. |
