因特網流量的快速增長，對骨干網的傳輸提出了更高的要求，為此我們研制了總吞吐率高達1.28T 比特高性能IPv4/v6 路由器。本路由器提供2.5GPOS ，10GPOS，100M 以太網，1000M 以太網，10GLAN 以太網，10GWAN 以太網等接口，可方便組網。本文簡要介紹了此路由器的體結構，并
深入研究了2.5GPOS 接口板的設計與實現。

Design and Implement based on VxWorks of 2.5GPOS Interface Board of T Bit Router Li Feng, Yang Jing (National Digital Switching System Engineering & Technological R&D Center,zhengzhou 450002,China) Abstract: The fast increase of Internet needs faster core transmission network, so we developed a high-powered IPv4/v6 router whose total throughput had reached 1.28 terabit bit. It is very convenient to set up a network because the router offers kinds of interfaces ,such as 2.5GPOS interface, 10GPOS interface，100M Ethernet interface，1000M Ethernet interface,10GLAN Ethernet interface，10GWAN Ethernet interface, and so on. This paper simply introduces the whole framework and deeply studies the design and implement of 2.5GPOS interface board. Key words: Router；SONET(Synchronous Optical Network)；SDH (Synchronous Digital
