Problems solved by technology

[0005] However, based on the above method, since Flowvisor needs to convert the passed protocol packets, this increases the delay in the transmission of OpenFlow control information in the protocol packets to a certain extent, especially when the control information of a segmented network occupies a large amount of bandwidth. resources, it will affect the processing and transmission of other shard network control information; in addition, because the protocol packets of each shard network need to be processed by Flowvisor, if Flowvisor fails, it will cause the failure of all shard networks

example 1

[0090] Example 1: Assuming that the operator performs virtual slicing of the network for wholesale to different virtual network tenants, the virtual network tenant can sign a contract with the operator, requiring the operator to provide a virtual slicing network that meets specific resource requirements. requirements, generate a virtual slice configuration file and send it to the virtual master controller, and the virtual master controller configures resources for each slice network according to the device resource capability information reported by the OpenFlow switch. For example, when a virtual network tenant needs large bandwidth resources and computing resources, the operator will allocate them reasonably based on the total bandwidth resources and CPU computing resources.

example 2

[0091] Example 2: Assume that the operator fragments the network to isolate different services, such as ordinary Internet services, voice services, etc., assuming that the voice service is of high importance, this requires the OpenFlow controller to be able to monitor the network operation status according to the Sharded forwarding resources are dynamically allocated. For example, when the resources of the OpenFlow switch are not very sufficient, the resource requirements of the voice service should be guaranteed first, and the allocation of resources in each service segment should be dynamically changed with reference to the importance of each service. This requirement can be realized by dynamically updating the shard network configuration file through the virtual master controller.

[0092] After the OpenFlow switch receives the slice network configuration file issued by the virtual main controller, it allocates forwarding resources for the virtual slice network according to...

Abstract

The invention discloses a virtual shard network implementing method and a switch. The method includes the steps: after a connection with a virtual master controller of an OpenFlow controller is established, device resource capacity is reported to the virtual master controller; a shard network configuration file including channel configuration information and forwarded resource configuration information, issued by the virtual master controller and generated according to the device resource capacity and a current configuration strategy is received; forwarded resources are distributed for virtual shard networks according to the forwarded resource configuration information; after a connection with each virtual shard controller of the OpenFlow controller is established according to the channel configuration information, forwarded resources of the virtual shard networks corresponding to virtual slave controllers are reported to the virtual shard controllers, so that the virtual shard controllers generate control information according to the acquired forwarded resources; the control information issued by the virtual shard controllers is received and correlated to the forwarded resources of the virtual shard networks corresponding to the virtual shard controllers.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for realizing a virtual slice network and a switch. Background technique [0002] With the development of the Internet, OpenFlow (Open Flow) technology has played a huge role in promoting the development of the network, and the virtualization technology based on the OpenFlow network is to virtualize the OpenFlow network into multiple virtual OpenFlow fragmented networks , each virtual slice network corresponds to an independent virtual slice controller and forwarding resources on the OpenFlow switch corresponding to the virtual slice controller, and an independent slice connection between the OpenFlow switch and the OpenFlow controller channels, and each virtual shard network is independent of each other and does not interfere with each other. [0003] The existing OpenFlow virtual slicing network introduces an intermediate device FlowVisor (OpenFlow flow virtual...
