摘要:

为了推进10GE接口在IP骨干网中的应用,本文对10GE接口在IP骨干网中的应用方式进行了探讨。首先对10GE接口与10G POS接口的成本和承载效率进行了分析和比较,然后对10GE LAN/WAN的OAM能力和性能进行了比较。接着对10GE LAN信号映射到OTN的方式进行了比较并提出了选择建议。最后分析了引入10GE接口对网络建设和维护的影响,并提出了10GE接口的应用建议。

Abstract:

The application of 10GE interface in the IP backbone network was discussed in this paper. First,the cost and bandwidth efficiency of 10GE and 10G POS interface were analyzed and compared. Then OAM capabilities and performance of 10GE LAN vs. WAN are compared. Next,different approaches for transport of 10GE LAN signals in optical transport network (OTN)were analyzed. Finally,the impact of 10GE interfaces to network construction and maintenance were analyzed,and the suggestion for application of 10GE interfaces in the IP backbone network was proposed.

Key words: 10GE LAN, 10GE WAN, OTN, IP backbone network
