分布式功能链接与选播路由

Distributed Function Chaining with Anycast Routing

Adrien Wion, Mathieu Bouet, Luigi Iannone, Vania Conan

摘要:

当前的网络越来越依赖于虚拟化中间盒来灵活地提供安全性、协议优化和策略合规性功能。因此,交付这些服务需要通过所需的虚拟设备序列来引导流量。目前的解决方案引入了一个新的逻辑集中式实体,通常称为协调器,需要构建自己的整个网络的整体视图,以便决定将流量定向到哪里。我们主张,这样的集中编排是没有必要的,相反,同样的目标可以通过增加网络层路由,以便包括服务的概念和它的链接。在本文中,我们通过设计这样一个系统来支持我们的主张。我们还提出了一个实施和早期评估,表明我们可以很容易地引导交通通过可用的资源。这种方法还提供了一些有前途的功能,如增量部署能力、多域服务链、故障恢复能力和易于维护。

英文摘要:

Current networks more and more rely on virtualized middleboxes to flexibly provide security, protocol optimization, and policy compliance functionalities. As such, delivering these services requires that the traffic be steered through the desired sequence of virtual appliances. Current solutions introduce a new logically centralized entity, often called orchestrator, needing to build its own holistic view of the whole network so to decide where to direct the traffic. We advocate that such a centralized orchestration is not necessary and that, on the contrary, the same objectives can be achieved by augmenting the network layer routing so to include the notion of service and its chaining. In this paper, we support our claim by designing such a system. We also present an implementation and an early evaluation, showing that we can easily steer traffic through available resources. This approach also offers promising features such as incremental deployability, multi-domain service chaining, failure resiliency, and easy maintenance.
