EAPS环在温州日报报业集团网络中的应用

Application of EAPS Ring in the Network of Wenzhou Daily Newspaper Group

文中介绍了温州日报报业集团网络互联中用到的EAPS环。由于温州日报报业集团是采用美国极进(Extreme)交换机,使用Extreme的EAPS技术,IP环的自愈恢复时间可缩短至几十毫秒,达到SDH的自愈效果。温州日报大楼有两报一网,而其它报社、杂志社及印务中心分别在不同地点。因此在外的汇聚层接入集团中心核心层基本采用ESRP(Extreme Standby Router Protocol)等链路备份协议。而考虑到集团今后数据冗灾,在其中一家硬件设施相对较好的报社(温州晚报)采用EAPS环来保证数据链路的畅通。

This paper presents the EAPS ring used in the interconnection of Wenzhou DailyNewspaper Group. The Group uses Extreme switching from USA and EAPS technology of Extreme, so the self-healing, recovery time of IP ring can be shorten to tens of ms, achieving the self-healing effect of SDH. The Wenzhou Daily Building includes two newspapers and one network, other newspapers, magazines, and printing center are located at other places. Therefore, the intercormection of external convergence layers into the core layer of the Group mainly uses the link backup protocol such as ESRP. In consideration of the future data redundant disaster the EAPS ring is used in Wenzhou Evening News where there is better hardware facility to ensure the smooth of the data link.
