Abstract

With the expansion of network scale, new network services are emerging. Segment Routing over IPv6 (SRv6) can meet the diverse needs of more new services due to its excellent scalability and programmability. In the intelligent 6-Generation (6G) scenario, frequent SRv6 Traffic Engineering (TE) policy updates will result in the serious problem of unsynchronized updates across routers. Existing solutions suffer from issues such as long update cycles or large data overhead. To optimize the policy-update process, this paper proposes a scheme called Synchronous Update with the Division and Combination of SRv6 Policy (SUDC). Based on the characteristics of the SRv6 TE policy, SUDC divides the policies and introduces Bit Index Explicit Replication IPv6 Encapsulation (BIERv6) to multicast the policy blocks derived from policy dividing. The contribution of this paper is to propose the policy-dividing and combination mechanism and the policy-dividing algorithm. The simulation results demonstrate that compared with the existing schemes, the update overhead and update cycle of SUDC are reduced by 46.71% and 46.6%, respectively. The problem of unsynchronized updates across routers has been further improved.

SUDC：同步更新与 SRv6 政策的划分与组合

随着网络规模的扩大，新的网络服务不断涌现。IPv6 网段路由（SRv6）凭借其出色的可扩展性和可编程性，可以满足更多新业务的不同需求。在智能 6 代（6G）场景中，频繁的 SRv6 流量工程（TE）策略更新将导致路由器间更新不同步的严重问题。现有解决方案存在更新周期长或数据开销大等问题。为了优化策略更新流程，本文提出了一种名为 "SRv6 策略分合同步更新（SUDC）"的方案。根据 SRv6 TE 策略的特点，SUDC 对策略进行了划分，并引入比特索引显式复制 IPv6 封装（BIERv6）来组播划分策略后得到的策略块。本文的贡献在于提出了策略划分和组合机制以及策略划分算法。仿真结果表明，与现有方案相比，SUDC 的更新开销和更新周期分别减少了 46.71% 和 46.6%。跨路由器不同步更新的问题也得到了进一步改善。
