Abstract

The invention discloses a POP point selection access method in an SD-WAN network, and belongs to the technical field of communication. The method is applied to a user gateway, and comprises the following steps: step S01, periodically detecting network operator lines associated with VPEs on all POP points in an SD-WAN network; step S02, obtaining a packet loss rate, an average delay value and a jitter value according to a detection result; carrying out instability scoring on each network operator line based on the packet loss rate, the average delay value and the jitter value; step S03, determining the instability score of each VPE based on the instability scores of all network operator lines associated with each VPE, and determining the network operator line with the lowest instability score in each VPE as the optimal network operator line in the VPE; and step S04, based on the instability scores of all the VPEs, taking the VPE with the lowest instability score as the VPE with the best stability, and then selecting the POP point corresponding to the VPE with the best stability and the optimal network operator line in all the VPEs. According to the method, the network quality is evaluated in time and the optimal POP point is selected.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a POP point selection access method in an SD-WAN network. Background technique [0002] SD-WAN network environment (refer to figure 1 ), SD-WAN CPE (Customer Periphery Equipment, hereinafter referred to as CPE) or VCPE (Virtual Customer Periphery Equipment) to the cloud network entrance is VPE (Virtual Provider Edge, the edge router of the service provider backbone network, deployed on the cloud, such as Ali Cloud). The SD-WAN operation network can provide users with a stable and high-quality network in the cloud, but the data from the customer gateway (CPE) to the SD-WAN cloud network entrance (VPE) is on the public network, and the network condition of the public network is very Complexity, different network operators, and factors such as packet loss, jitter, and delay in the public network will have a great impact on the overall stability of the SD-WAN network.
