Abstract: Some embodiments provide a method of implementing capacity-aware load balancing across a set of data compute nodes (DCNs) by reducing latency for the set of DCNs. From the set of DCNs, the method identifies (1) a first subset of DCNs including DCNs that have a latency that is higher than an average latency computed for the set of DCNs and (2) a second subset of DCNs including DCNs that have a latency that is lower than the average latency computed for the set of DCNs. For each DCN in the first subset of DCNs, the method assigns to the DCN a weight value that corresponds to a target latency computed for the set of DCNs. Based on the assigned weight values for the first subset of DCNs, the method computes an excess weight value to be redistributed across the second subset of DCNs. The method redistributes the computed excess weight value across the second subset of DCNs.

Abstract: In some embodiments, a method receives a set of packets for a flow and determines a set of features for the flow from the set of packets. A classification of an elephant flow or a mice flow is selected based on the set of features. The classification is selected before assigning the flow to a network resource in a plurality of network resources. The method assigns the flow to a network resource in the plurality of network resources based on the classification for the flow and a set of classifications for flows currently assigned to the plurality of network resources. Then, the method sends the set of packets for the flow using the assigned network resource.

Abstract: Some embodiments provide a method of implementing context-aware routing for a software-defined wide-area network, at an SD-WAN edge forwarding element (FE) located at a branch network connected to the SD-WAN. The method receives, from an SD-WAN controller, geolocation route weights for each of multiple cloud datacenters across which a set of application resources is distributed. The application resources are all reachable at a same virtual network address. For each of the cloud datacenters, the method installs a route for the virtual network address between the branch network and the cloud datacenter. The routes have different total costs based at least in part on the geolocation metrics received from the SD-WAN controller. The SD-WAN edge FE selects between the routes to establish connections to the set of application resources.
