Embodiment Construction

[0064] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0065] see figure 1 , the embodiment of the present invention provides a resource allocation method, which is applicable to a control-forwarding separation network, and the method may be executed by a controller in the network, or may be executed by other network devices. The method of the present invention In the embodiment, the Controller is used as an example for de...

Abstract

The present invention provides a resource allocation method, controller, and system, wherein a resource allocation method includes: the controller Controller receives a flow table establishment request message, and the flow table establishment request message includes information allocated for the flow table entries that need to be established. A resource application identifier and a flow table entry identifier, the resource application identifier is used to indicate the resources that the Controller needs to allocate, and the flow table entry identifier is the identifier of the flow table entry that needs to be established; according to the resource application identifier, allocate resource information, so that the forwarding device establishes the flow table entry according to the allocated resource information, so as to realize the unified allocation of resources used by the transition technologies by the controller, so that each transition technology can share an address pool to realize centralized management of resources, and then When resource allocation is performed, resources can be obtained from the shared address pool for allocation, avoiding waste of resources caused by using independent address pools for each transition technology.

Description

technical field [0001] The present invention relates to the field of transition technology, in particular to a resource allocation method, controller and system. Background technique [0002] During the evolution process from Internet Protocol version 4 (Internet Protocol version 4, IPv4) network to Internet Protocol version 6 (Internet Protocol version 6, IPv6) network, there are various IPv6 evolution technologies, such as lightweight dual stack (Dual Stack Lite, DS -lite), IPv4 to IPv4 network address translation (Network AddressTranslation4to4, NAT44) and lightweight IPv6 transition (Light-weight4over6, LW4over6) and other transition technologies. During the transition from IPv4 to IPv6, the application (Application, APP) of each transition technology needs to independently allocate addresses for it, and each APP runs on a corresponding server. [0003] In the prior art, when an APP of each transition technology generates a flow table establishment request message, it o...
