摘　　要：目前互联网面临着越来越严重的安全、移动、海量数据传输等技术挑战,人们希望用新的网络体系结构来解决当前遇到的问题.但是新的网络体系结构大多对路由器提出了很高的要求,需要支持多种网络体系结构下不同寻址方式以及复杂变长的查找匹配等,实现存在困难.而且不同的体系结构之间关联很少,难以在转发层进行统一.本文通过借鉴OpenFlow和MPLS的思想,提出了基于标签的多协议承载机制.该机制为不同的网络层协议提供了统一的转发层抽象,同时基于标签的查找能加快报文处理的速度,减少了表项.As Internet is facing more and more challenges including security, mobility, massive data transfer and so on, researchers hope to resolve these problems by exploring new network architectures. But these emerging architectures require high performance of touters, as the touters need to support different ways of addressing and complex variable length matching, which is quite difficult to re- alize. Besides since there is little correlation between different architectures, it is hard to unify the forwarding plane. Depending on the ideas of OpenFlow and MPLSnthis paper proposes a label-based multi-protocol supported mechanism. This mechanism can provide a universal abstract of forwarding plane for different network protocols,speed up packet forwarding and decrease items through labed- based lookup.
