摘要： The present technology intelligently selects routes to be distributed to edge network device from SD-WAN controllers. Rather than indiscriminately distributing routes, the present technology utilizes logic to account for route viability conditions to determine whether a route between a first edge network device and a second edge network device is likely to be usable between the edge network devices.

摘要： This disclosure describes techniques and mechanisms for utilizing affinity routing in SDWAN networks. The techniques may enable network administrators to assign and/or configure affinity numbers to hub(s) and/or gateway(s), tunneling interface(s), service(s), etc., as well as affinity-preference-order(s) to edge device(s) within the network. Network administrators may also configure control polic(ies). The techniques enable a scalable and simplified way to automatically load-balance traffic across different gateways within a network, while reducing network resource usage. The techniques may utilize routing affinity to achieve a variety of networking related functionalities, including automatic load-balancing of traffic, provisioning of active and backup gateways, optimal route distribution to routers from routing controllers, optimized service placement for edge routers, without the need for any policy configuration at all, let alone complex policies.

摘要： A method of creating a connection between a controller and plurality of edge devices may include reading, by a data plane development kit (DPDK) of the controller, a plurality of packets having a common destination port from the plurality of edge devices, and demuxing, by the DPDK, a number of frames of the plurality of packets based on a hash of the plurality of packets, the hash altering the common destination port of the plurality of packets with a corresponding number of sham destination ports. The method may also include, with a TUNTAP interface, injecting the plurality of packets into a network kernel, and with the network kernel, delivering the plurality of packets to a respective one of a plurality of daemon instances.
