Abstract: According to an embodiment, a node comprises one or more processors operable to execute instructions to cause the node to perform operations that comprise receiving a packet from a first node associated with an SD-WAN domain. The packet comprises a header indicating a TLOC associated with a second node to send the packet, the second node associated with an SR domain. The operations comprise determining that the TLOC corresponds to a virtual TLOC used in the SD-WAN domain to identify the second node that is in the SR domain and, in response, determining a second node identifier used in the SR domain to identify the second node. The operations further comprise preparing the packet to be communicated via the SR domain. Preparing the packet comprises including the second node identifier in the packet. The operations further comprise sending the packet comprising the second node identifier to the second node.

Abstract: A tunnel endpoint of a virtual network monitors the flows between the tunnel endpoint and at least one other tunnel endpoint. The virtual network spans a physical network. A flow identifier for each flow is determined based on packet headers of packets in each respective flow. A path identifier for each flow is also determined based on the packet headers of the packets in each respective flow. Each path identifier indicates a route that the respective flow takes in the physical network to reach the respective destination tunnel endpoint. The path identifier and the flow identifier of the respective flows are then transmitted to a controller of the virtual network.

Abstract translation: 虚拟网络的隧道端点监视隧道端点与至少一个其他隧道端点之间的流。 虚拟网络跨越物理网络。 每个流的流标识符基于每个相应流中的分组报头来确定。 每个流的路径标识符也是基于每个流中的分组的分组报头来确定的。 每个路径标识符指示相应流在物理网络中到达相应目的地隧道端点的路由。 然后将路径标识符和各个流的流标识符发送到虚拟网络的控制器。
