具有策略驱动路由的主干网
摘要：
本发明涉及具有策略驱动路由的主干网。源设备获得包括目的地地址和有效载荷两者的数据分组。源设备基于一个或多个策略选择多个出口点地址中对应于目的地地址的出口点地址。源设备使用包括所选出口点地址的头部来封装数据分组，并且经封装的数据分组被提供给主干网。经封装的数据分组基于出口点地址来通过主干网来路由，并且主干网的边缘路由器标识边缘路由器的对应于出口点地址的接口。从经封装的数据分组移除头部，并且数据分组被添加到接口的缓冲器，以便路由到主干网外部的一个或多个其他设备。
摘要（英）：

The invention relates to a backbone network with policy driven routing. A source device obtains a data packet that includes both a destination address and a payload. The source device selects an exit point address of multiple exit point addresses corresponding to the destination address based on one or more policies. The source device encapsulates the data packet with a header that includes the selected exit point address, and the encapsulated data packet is provided to the backbone network. The encapsulated data packet is routed through the backbone network based on the exit point address, and an edge router of the backbone network identifies an interface of the edge router that corresponds to the exit point address. The header is removed from the encapsulated data packet, and the data packet is added to a buffer of the interface for routing to one or more other devices outside of the backbone network.
