Embodiment 1

[0070] When deploying SDN disaster recovery implementation, such as figure 2 As shown in the figure, it is necessary to configure the preset flow table on the SDN switches B and C connected to the active and standby data centers and the SDN data forwarding switch A on the user access side. include:

[0071] Configuring related flow tables on the SDN data forwarding switch A on the user access side includes:

[0072] Create a flow table whose destination address is the user host.

[0073]

[0074] Create a flow table whose destination address is the primary data center.

[0075]

[0076] The relevant flow tables for accessing the SDN switch B in the active data center include:

[0077] Create a flow table whose destination address is the primary data center.

[0078]

[0079] Create a flow table whose destination address is the user.

[0080]

[0081] Accessing the SDN switch C in the backup data center configures related flow tables including:

[0082] Creat...

Abstract

The invention discloses an SDN-based disaster recovery system and a data disaster recovery method thereof. The system comprises an intelligent scheduling module, a centralized controlling module and a data forwarding module, wherein the intelligent scheduling module is arranged in an intelligent scheduling layer, and is used for monitoring link state changes when a main data center stored in an SDN centralized controller is accessed to an SDN switch and issuing an instruction to the SDN centralized controller when the main data center is abnormal or recovery is abnormal to complete a flow table operation of the SDN switch by the SDN centralized controller; the centralized controlling module is arranged in a centralized controlling layer, and is used for storing a link state of the controlled SDN switch and completing the flow table management of the controlled SDN switch according to an instruction issued by an SDN intelligent scheduler; and the data forwarding module is arranged on an SDN data forwarding switch at a user access side, and is used for forwarding data according to a flow table issued by the controller.

Description

technical field [0001] The invention relates to the field of SDN extended information technology, in particular to an SDN-based disaster recovery system and a data disaster recovery method thereof. Background technique [0002] The full name of SDN is Software Defined Network (Software Defined Network). Its core technology is to separate the control plane of network equipment from the data plane, thereby realizing the flexible control of network traffic and providing a platform for core network and applications. [0003] At present, the demand for data center disaster recovery has increased sharply, including: building disaster recovery centers in different local regions, building disaster recovery centers in different places, and realizing low-latency, fast and stable switching between disaster recovery centers. The traditional disaster recovery solution needs to invest a lot of expensive professional network equipment and can be completed after long-term deployment, and th...
