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

Embodiment Construction

[0033] see figure 1 , the embodiment of the present invention provides a network architecture, the network architecture includes: a controller, a vBNG-CP network element, a core router (core router, CR), a forwarding device, and a plurality of vBNG-UP network elements.

[0034] Optionally, the forwarding device may be a switch (switch, SW) or an optical line terminal (optical line termination, OLT), or the like.

[0035] For any vBNG-UP network element among the plurality of vBNG-UP network elements, the vBNG-UP network element includes at least one interface, and each interface includes at least one sub-interface. Each interface in the vBNG-UP network element includes a user-side interface and a network-side interface, and each sub-interface in the vBNG-UP network element includes a user-side sub-interface and a network-side sub-interface. The vBNG-UP network element can be connected to devices such as the vBNG-CP network element, CR, and controller through the network side ...

Abstract

The embodiment of the present application discloses a network traffic migration method and device, which belong to the communication field. The method includes: obtaining the bandwidth utilization parameter of each vBNG-UP network element in M ​​vBNG-UP network elements, M being an integer greater than 1; the bandwidth utilization parameter of the first vBNG-UP network element reaches the first threshold , according to the sum of the bandwidth occupied by the network traffic of each terminal device in the first device group to be migrated on the first vBNG-UP network element and the bandwidth usage parameters of the vBNG-UP network elements in the vBNG-UP network element group, determine The second vBNG‑UP network element; migrate the network traffic of each terminal device in the first device group to be migrated to the second vBNG‑UP network element. The application can avoid the problem that the total bandwidth occupied by the vBNG-UP network element approaches or reaches the total bandwidth of the vBNG-UP network element.

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. ...
