Embodiment Construction

[0023] A method for achieving high availability of control components under the architecture of separate network components for forwarding and control is given. The redundant backup measures of the control components are used to ensure that network devices provide uninterrupted services, and at the same time, the system performance is improved through load balancing.

[0024] A method to achieve high availability of control components under the architecture of separate network components for forwarding and control.

[0025] Including the following steps:

[0026] 1) Initially determine the available control list through the control management unit, and notify the forwarding through the forwarding management unit;

[0027] 2) Each control component monitors the status changes of other control components, and maintains a list of all available control components in the network component and their load conditions;

[0028] 3) The forwarder uses the list of available controls acquired ...

Abstract

The invention discloses a method for realizing the high availability of control elements under the transmitting and the controlling of separating a networkware framework, which comprises the following steps: 1) an available control element list is determined through a control element management unit and informs a forwarding element through a forwarding element management unit; 2) each control element monitors the change of the states of other control elements and maintains the available control element list and the load condition; 3) after the forwarding element acquires the available element list, the forwarding element asks the control elements for the available control element lists, the load condition and a load balancing method one by one and selects the control element actively; 4) more than two control elements bear the network service function facing to a plurality of forwarding elements and trigger the forwarding elements to switch the control elements according to the load condition of the control elements; 5) data is backup among a plurality of control elements to realize the consistency of related data. The invention adopts a plurality of control elements to increase the availability of the control elements and improves the overall performance of the networkware through the load balance.

Description

Technical field [0001] The invention belongs to the field of communications, and specifically relates to a method for realizing high availability of a control component under a network component architecture of forwarding and control separation. Background technique [0002] In this information ubiquitous society, the most critical problem facing computing systems and communication systems is how to establish and maintain the stability and continuity of the system. For network equipment, computer systems are mainly used to provide timely and reliable information and data processing. Computer hardware and software will inevitably fail. These failures may cause great losses to network equipment, and even the entire network. Termination and paralysis of services. For those network equipment used for critical data communications, any shutdown will result in serious property losses. In addition, because the network is paralyzed, the reputation of the enterprise or the company is affec...
