Abstract: A method and apparatus for connecting multiple customer sites over a wide area network (WAN) using an overlay network is described. In one embodiment of the invention, each one of multiple customer edge (CE) routers establishes a Border Gateway Protocol (BGP) session with one or more BGP route reflectors and announces their private IP network prefixes and one or more transport IP addresses to reach that CE router. The BGP route reflector(s) reflect those IP network prefixes and the one or more transport IP addresses to reach that specific CE router to the other CE routers. The CE routers receive those reflected IP network prefixes and the corresponding transport IP address(es) to reach that CE router in which those IP network prefixes belong and register them in their corresponding routing/forwarding data structures. In this way, the CE routers learn how to reach each other.

Abstract: In general, techniques for implementing a flow distribution service using a plurality of traffic nodes that may operate as processing nodes of a distributed computing system are described. In some examples, the traffic nodes in the aggregate form a virtual appliance configured to apply a network service to packet flows.

Abstract translation: 一般来说，描述了使用可以作为分布式计算系统的处理节点操作的多个业务节点来实现流量分发服务的技术。 在一些示例中，聚合中的流量节点形成被配置为向分组流应用网络服务的虚拟设备。
