东数西算下面向业务的路由策略分析与探索

摘要：基于各类业务对算力与网络指标的需求，结合当前网络流量现状与未来网络流量发展趋势，分析了包含算力业务的路由策略与实现机制，探索在“东数西算”场景下，面向业务和算力分布的路由策略。提出了一种基于业务属性与算力资源分布的混合式路由策略，将全国分成若干“算力区域”，在不同算力区域之间采用集中式路由决策，在算力区域内部采用分布式路由决策。该策略能够提供一种安全、灵活、高效的全局路由方法。

Abstract: Based on the demand of various services for computing power and network indicators, combined with the current status of network traffic and the future trends of network traffic development, the routing strategy and implementation mechanism including computing power business are analyzed, and the routing strategy oriented to business and computing power distribution under the scenario of "East-to-West Computing" is explored. A hybrid routing strategy based on service attributes and computing power resource distribution is proposed, which divides the whole region into several "computing power regions". The centralized routing strategy is adopted between different computing power regions, and the distributed routing strategy is adopted within the computing power regions. The hybrid routing strategy can provide a secure, flexible, and efficient overall routing strategy.
