众所周知，BGP限制了策略的表达能力，并导致难以理解、重用和发展的不受控制的策略交互。我们认为，使用路径向量系统作为域间政策的载体是这些限制的根本原因。为此，我们提出了一种替代的政策方案，内置在一个软件定义的控制器解耦的路径向量系统的政策制定。我们不是将策略视为路由的硬连线属性，而是让策略流动、交互和联合收割机来影响端到端路由。这种新的软件定义方案为策略语言、路由决策和冲突解决设计创造了新的空间，从而实现更灵活的策略、更清晰的策略执行和受控的策略交互。作为我们的愿景的实现，我们提出了一个实现，使用数据完整性约束表示和推理路由策略，解决分散域间环境中的独特挑战。
BGP is known to restrict policy expressiveness and induce uncontrolled policy interactions that are hard to understand, reuse, and evolve. We argue that the use of a path vector system as the carrier of interdomain policies is the root cause of these limitations. To this end, we propose an alternative policy scheme built in a software-defined controller to decouple policy making from the path vector system. Rather than treating policies as hardwired attributes of a route, that are configured and consumed as the route goes through the path vector decision process, we let policies flow, interact, and combine to influence end to end routes. This new software-defined scheme creates new space for policy language, route decision, and conflict resolution design, towards more flexible policies, cleaner policy enforcement, and controlled policy interaction. As a realization of our vision, we present an implementation that uses data integrity constraints for representing and reasoning about routing policies, addressing unique challenges in the decentralized interdomain environment.
