Network flow migration method and device

Abstract

The embodiment of the invention discloses a network flow migration method and device, and belongs to the field of communication. The method comprises the following steps: acquiring a bandwidth use parameter of each vBNG-UP network element in M vBNG-UP network elements, wherein M is an integer greater than 1; when the bandwidth use parameter of the first vBNG-UP network element reaches a first threshold value, determining a second vBNG-UP network element according to the sum of bandwidths occupied by the network traffic of the terminal devices in the first device group to be migrated on the first vBNG-UP network element and the bandwidth use parameter of the vBNG-UP network element in the vBNG-UP network element group; and migrating the network traffic of each terminal device in the first device group to be migrated to the second vBNG-UP network element. By adopting the method and the device, the problem that the total bandwidth occupied by the vBNG-UP network element is close to or reaches the total bandwidth of the vBNG-UP network element can be avoided.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a method and device for migrating network traffic. Background technique [0002] The communication network includes virtual broadband network gateway control plane (virtual broadband network gateway control plane, vBNG-CP network element) and virtual broadband network gateway user plane (virtual broadband network gateway user plane, vBNG-UP network element) and other network elements, a vBNG-CP A network element can manage at least one vBNG-UP network element. When a terminal device requests to access the communication network, the vBNG-CP network element can select a vBNG-UP network element for the terminal device, and then the terminal device accesses the communication network through the vBNG-UP network element. After the user accesses the communication network, the The vBNG-UP network element can be used to transmit the network traffic of the terminal equipment. ...

AI Technical Summary

Problems solved by technology

[0005] Although the above solution can balance the utilization rate of equipment among different vBNG-UP network elements, different network traffic consumes different bandwidth, some network traffic consumes a large bandwidth, and some network traffic consumes a small bandwidth , so that the sum of the bandwidth consumed by each network traffic transmitted on some vBNG-UP network elements may approach or reach the total bandwidth of the vBNG-UP network element, resulting in problems such as traffic congestion
