Embodiment Construction
[0053] It is to be understood that the specific embodiments described herein are intended to explain the present invention and is not intended to limit the invention.
[0054] Solution embodiment of the present invention are: by calculating the load value of the forwarding plane rotation control VBRAS split architecture according to a preset equalization algorithm, and the forwarding plane determines a target current value according to the lowest load value of the load; the target forwarding the surface of the first request to report the authentication signaling control plane, the forwarding user generates and sends to the control target forwarding plane surface; obtaining the target forwarding plane forwarding plane switching state, the switching state of the forwarding plane according to forwarding the corresponding service user is protected, to achieve simple logic, fault forwarding plane may avoid possible protection switching loss of information caused by the user, to achieve...

The invention discloses a service protection method and system for a forwarding and control separation architecture VBRAS, and the method comprises the steps: calculating a load value of each forwarding plane of the forwarding and control separation architecture VBRAS according to a preset balance algorithm, and determining a target forwarding plane with a current lowest load value according to the load values; the target forwarding plane reporting the first request authentication signaling to a control plane, generating a user forwarding table on the control plane and sending the user forwarding table to the target forwarding plane; and obtaining the forwarding plane switching state of the target forwarding plane, and protecting the service corresponding to the user forwarding table according to the forwarding plane switching state, so that the implementation logic is simple, user information loss caused by fault forwarding plane protection switching can be avoided to the greatest extent, load balance of each forwarding plane is realized, a traditional entity BRAS in a high service density scene can be replaced, various scenes can be deployed, the performance is strong, resource redundancy is avoided, and multiple service protection modes including an N: 1 mode can be realized.
Description
Technical field [0001] The present invention relates to communication technologies, particularly to a rotation control method and system for service protection in VBRAS split architecture. Background technique [0002] Virtual Broadband Access Server (Virtual Broadband Remote Access Server, VBRAS) As a new broadband access server (Broadband Remote Access Server, BRAS) device form, there are two architectures ways: centralized control transfer and separation means. [0003] After the virtualization VBRAS occurs turn generates a new protection, protection of the pool, this protection, the ability VBRAS examples consistent set of the plurality of business form a resource pool VBRAS, user session control session Activity sharing on each pooled VBRAS instance, but an instance fails VBRAS, carrying the service will be borne VBRAS to other examples of the pool; in this way advantage can be realized N: 1 protection scenario, the disadvantages rotation control is only suitable way VBRAS c...
