Abstract: In one embodiment, methods are described to measure bandwidth limits through multiple test sites. A testing quantity of network packets is generated, the network packets are sent through a service provider network to a plurality of receivers at a testing transmission rate that exceeds an upstream transmission rate limit of the service provider network, a report indicating a received number of packets is received from each of the plurality of receivers, and an upstream transmission rate limit of the service provider network is determined based on the testing transmission and the reports. By using multiple test sites, potential bottlenecks at any one test site are reduced. A similar method can be used to calculate a downstream transmission rate limit. Once measured, the bandwidth limits may be used to adjust quality of service on an edge router or compared against a known service level agreement of the service provider network.

Abstract: Techniques described herein can perform per-queue network performance measurement mapping, in which per-queue network performance measurements are determined and then mapped back to service level agreement (SLA) classes assigned to use the queues. Network traffic associated with an SLA class can be processed through an assigned router queue. Wide area network (WAN) as well as local performance measurements from the assigned queue can be combined to determine a combined performance measurement associated with the assigned queue. The combined performance measurement can then be mapped or otherwise associated with the SLA class. Similarly, combined performance measurements can be determined for other router queues and mapped or otherwise associated with other SLA classes.

Abstract: In one embodiment, a method includes receiving, by a network node, traffic within a hierarchical software-defined wide area network (SD-WAN) network. The method also includes determining, by the network node, a destination region of the traffic. The destination region is within the hierarchical SD-WAN network. The method further includes classifying, by the network node, the traffic based on a destination match condition. The destination match condition is associated with two or more destination regions.
