Description
Technical Field
The invention belongs to the technical field of communication, and particularly relates to a control item arranging method and device for butting multi-manufacturer equipment.
Background
In a network architecture in which a control plane and a forwarding plane are separated from each other, multiple types of protocols exist in the interface between the control plane and the forwarding plane, such as open flow (OpenFlow), Border Gateway Protocol (BGP), Path Computing Element Protocol (PCEP), and the like, the flow tables are different in single-stage and multi-stage flow tables and all conform to the Protocol specification, and similar problems also exist in the control of other control items such as an optical layer, and even the same Protocol may have differences caused by different versions and vendor-defined options. The method brings a lot of compatibility problems for the butt joint of a control plane and a forwarding plane, and the industrial development requires the generalization of the forwarding plane, can realize the butt joint of multiple manufacturers so as to avoid the binding of the manufacturers, really achieve the open standard and realize flexible programming.
The existing solutions for the network controller to interface with the repeater have several ways, which can be divided into:
vertical chimney type: in a vertical management platform (chimney system), a controller is in butt joint with a corresponding repeater, so that the problem of butt joint of equipment of multiple manufacturers does not exist basically; scene customization mode: customizing the arrangement mode of control items such as a flow table and the like in a controller according to the requirements of application scenes, for example, integrating a plurality of functional modules into a single module and uniformly managing the arrangement and generation mode of the control items; and (3) controlling by domains/factories: the repeaters in the same manufacturer/same control item form are controlled by one controller.
The drawbacks of these solutions:
vertical chimney type: control butt joint in different manufacturers/different control item forms is not considered, and the method does not conform to the requirements of clients and industrial trends of open butt joint and removal of manufacturer binding.
Scene customization mode: the customization needs to be carried out according to the customer requirements and the deployed manufacturer models, so that each project basically needs to be changed and customized, the workload is large, and if a plurality of and various repeaters with incompatible control item forms are deployed in a controlled network domain in a single project, the single controller cannot cope with the situation.
And (3) controlling by domains/factories: the single controller HAs no network global view angle, cannot globally schedule resources, needs the super controller or performs east-west information exchange among the controllers, increases the complexity and the cooperation difficulty of the controllers, and HAs larger cooperation difficulty when improving the reliability through a High Availability (HA) cluster.
