通用分组网络寻址路由与标识演进方法及系统

Method and system for general packet network addressing routing and identifier evolution

未来的网络通信需求动态多样,网络层功能也应适时而变,因此对网络可演进性的研究具有重要意义.多标识网络作为一种兼容性极强的网络架构,网络层功能十分丰富,但仍缺少网络演进性设计.本文为多标识网络设计了一种通过标识扩展来支持网络体系不断演进的方案,包括对标识空间进行形式化定义,设计标识回退候选标识的优先级排序算法以及设计支持标识扩展的路由转发协议;并且在ndnSIM网络仿真环境和多标识网络测试床中实现了上述方案,评估了标识扩展方案的可行性和性能.实验结果表明相比于标识扩展机制给网络架构带来的益处,其性能损失在可接受的范围内.

Future network communication demands are dynamic and diverse,requiring a flexible and scalable network layer.Thus,investigating the network evolution is of great importance.Multi-identifier network(MIN)has emerged to provide a novel network layer with rich functions as a highly compatible network architecture.However,the current design of network evolution in the MIN is still in a preliminary stage.In this work,a network evolution scheme is proposed based on the identifier extension for the MIN.This scheme defines the formal description of the network identifier space.Meanwhile,a priority-based sorting algorithm is designed for candidate identifiers in an identifier fallback mechanism.Additionally,a novel routing and forwarding protocol is designed to support identifier extension.Extensive experiments are performed both on the ndnSIM simulator and MIN testbed,revealing the effectiveness and superiority of the proposed scheme,albeit with a slight performance loss.
