Problems solved by technology

[0006] Both of the above two solutions have certain defects: Although solution 1 fully realizes the NFVization of VBRAS, it must rely on a specially customized core/aggregation switch. If the DC does not purchase such a switch in the early stage of establishment, it will not be able to carry out business; Solution 2 does not realize the overall virtualization of VBRAS. In addition, it is necessary t

Embodiment Construction

[0063] The embodiment of the present invention provides a method for load sharing of virtual BRAS equipment in a data center, comprising the following steps:

[0064] The controller starts two VMs in the data center, configures the two VMs as control plane VMs, and configures their BGP (Border Gateway Protocol, Border Gateway Protocol) parameters and virtual IP addresses;

[0065] The two control plane VMs establish an MP-BGP association relationship based on BGP parameters and virtual IP addresses, establish a virtual service control network and an internal cluster data synchronization protocol based on VXLAN (VirtualExtensibleLAN, Virtual Extended Local Area Network), and request the controller to start forwarding Surface VM;

[0066] The controller starts a new VM and configures it as a forwarding plane VM. The forwarding plane VM joins the virtual service control network by establishing a VXLAN tunnel. The control plane VM learns the virtual IP address of the forwarding pl...

Abstract

The invention discloses a virtual BRAS equipment load sharing method and system in a data center, and relates to the technical field of network function virtualization, and the method comprises the steps: building a control plane VM and a forwarding plane VM according to different working properties; unifying a control plane VM and a forwarding plane VM into an overlay virtual service control network constructed based on a VXLAN, and using VM roles and VM load weight values as extension attributes of MP-BGP update messages, so that automatic discovery and load weight exchange processes of VM nodes are realized; on the basis of a load weight value, enabling a control plane VM reasonably to allocate three layers of service flows of a user on different forwarding planes VM for processing, andenabling a forwarding plane VM to allocate user access signaling flows on different control plane VMs for processing, so that load sharing of the whole system is realized, and the overall concurrencyand reliability are improved.

Description

technical field [0001] The invention relates to the technical field of network function virtualization, in particular to a method and system for load sharing of virtual BRAS equipment in a data center. Background technique [0002] With the continuous deepening of NFV (Network Function Virtualization, network function virtualization) technology, more and more traditional telecom network element devices have begun to develop in the direction of pure software and virtualization. Among them, the BRAS (Broadband Remote Access Server, Broadband Remote Access Server) device, which serves as the control point for users to access the network of the telecom operator, is very suitable for virtualization and placed in the operator's data center for operation. This is because the BRAS equipment directly handles the AAA authentication process and billing process for user access, and is closely related to the operator's accounting system. Centralized control and management in the DC (Data...
