Problems solved by technology

However, a vBNG usually supports only one forwarding VM to provide data forwarding function for network users
That is to say, one vBNG cannot provide multiple forwarding VMs for data forwarding function of network users at the same time
Therefore, it is difficult for vBNG to flexibly respond to dynamically changing network service requirements

Embodiment Construction

[0160] The inventor found through research that the vBNG includes a forwarding VM for providing a data forwarding function for network users. However, in the traditional vBNG, due to the lack of a processing mechanism for distributing data packets from user terminals to different forwarding VMs for forwarding, all data packets from user terminals will be sent to the same forwarding VM for forwarding processing, and It cannot be distributed to multiple different forwarding VMs for forwarding processing. Therefore, traditional vBNG usually only supports one forwarding VM to provide data forwarding function for network users, that is, all business requirements for data forwarding will be concentrated on the same forwarding VM, but traditional vBNG cannot support multiple forwarding VMs to provide data for network users at the same time The forwarding function, that is, the business requirements that cannot be forwarded are distributed to multiple forwarding VMs, so it is impossib...

Abstract

The embodiment of the invention discloses a virtual network device. The virtual network device is used for realizing the function of a broadband network gateway BNG. The virtual network device comprises a load balancing unit and a first forwarding unit; the load balancing unit is used for receiving first data messages from a first user terminal; the first forwarding unit is determined according to the first data messages and a first corresponding relation; the first data messages are sent to the first forwarding unit; wherein the first corresponding relation indicates the mapping from the first user terminal to the first forwarding unit; and the first forwarding unit is used for receiving and forwarding the first data messages. Moreover, the embodiment of the invention also discloses a method for realizing load sharing in the virtual network device.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a virtual network device and a method for realizing load sharing in the virtual network device. Background technique [0002] In the network, a broadband network service gateway (English: Broadband Network Gateway, BNG for short) is used to provide functions such as authorized access, billing, flow control, and data forwarding of network users. For example, a broadband remote access server (English: Broadband Remote Access Server, BRAS for short) is a kind of BNG. Driven by the technology of network virtualization and cloudification, the network can use virtual network devices to realize the functions of BNG. The virtual network device may be called a virtual broadband network gateway (English: virtual Broadband Network Gateway, vBNG for short). For example, a virtual broadband remote access server (English: virtual Broadband Remote Access Server, vBRAS for short) is a k...
