基于标地分离自动绑定的网络冗余抗毁设计

Network Redundancy Anti-destruction Design Based on Locator/Identifier Separation and Automatic Binding

高等级网络冗余抗毁效能提升是党政、金融等行业专网的紧迫需求,而传统路由协组网模式由于架构扁平化,难以在大规模组网场景下提供网络损毁后业务通联恢复时间的上界保证。首先,介绍了一种基于标地分离架构的新型去中心化自动映射机制,可实现用户IP前缀路由与广域网路由器设备编号的分级关联绑定,通过2级多态转发查表、定制化标识报文封装和多归接入自适应择优转发等专用改造,实现大规模组网场景下带确定性中断恢复时间上界的高等级冗余抗毁保证。其次,给出了总体架构、关键数据结构和主体工作流程等设计。该设计具有较好的工程实施参考价值。

Enhancing the redundancy anti-destruction performance of high-level networks is an urgent requirement for private networks in the party,government,finance and other industries.However,the conventional routing protocol networking model is difficult to provide an upper bound guarantee of service communication recovery time after network damage in large-scale networking scenarios due to its flat architecture.This paper first introduces a new decentralized automatic mapping mechanism based on the locator/identifier separation architecture,which can implement a hierarchical association binding of user IP prefix routing and WAN router equipment number,and realize the high-level redundancy anti-destruction guarantee with deterministic interruption recovery time upper bound in large-scale networking scenarios through the special modification of 2-level polymorphic forwarding lookup table,customized identification packet encapsulation and multi-homing access adaptive preferential forwarding,and so on.Then,it gives the design of the overall architecture,key data structure and main workflow,etc.,and it has a good reference value for engineering implementation.
