Problems solved by technology

[0004] However, in the above-mentioned process where the VNFM requests the VIM designated by the NFVO to allocate resources for the VNF managed by the VNFM, since the number of VIMs that can establish connections with the VNFM is limited, when the number of VIMs that have established connections with the VNFM reaches the If the VNFM has not established a connection with the VIM specified by the NFVO when the threshold of the number of VIMs that are connected to the VNFM is set, the VNFM cannot establish a connection with the VIM specified by the NFVO because there are no idle connection resources. The connection between VIMs, so that the VNFM cannot request the VIM designated by NFVO to allocate resources for the VNF

Embodiment 1

[0152] An embodiment of the present invention provides a method for releasing a connection, such as figure 2 As shown, the method includes:

[0153] S101. The first node determines a second node that is allowed to release a connection from multiple second nodes, where the multiple second nodes are nodes that have established a connection with the first node.

[0154] It should be noted that, in this embodiment of the present invention, the first node may be a VNFM or a VIM. Specifically, when the first node is a VNFM, the multiple second nodes are multiple VIMs, and the multiple VIMs have established connections with the VNFM; when the first node is a VIM, the multiple second nodes are Multiple VNFMs, and the multiple VNFMs have established connections with the VIM.

[0155] Further, the first node may determine a second node that is allowed to release the connection from multiple second nodes according to an instruction of the management node. For example, when the manage...

Embodiment 2

[0172] The embodiment of the present invention provides a method for releasing a connection, which can be used in various application scenarios. The method for releasing a connection provided by the embodiment of the present invention will be exemplarily described below in the following three possible application scenarios.

[0173] In the first possible application scenario, the management node initiates the process of releasing the connection. Wherein, the management node can be the NFVO in the NFV system, and can also be other functional nodes with the function of NFVO, that is, the management node can be a functional node capable of scheduling resources managed by all VIMs in the NFV system, and the present invention does not make any limit.

[0174]In the management node, a resource mapping table is set, and the resource mapping table records the resource application status of each VNFM in the NFV system, the resource allocation status of each VIM, and the connection stat...

Embodiment 3

[0365] Such as Figure 11 As shown, the embodiment of the present invention provides a device for releasing a connection, and the device for releasing a connection may be as follows figure 2 , or as in Figure 4 To such as Figure 10 The physical device of the first node described in the embodiment shown in any of the drawings may also be the physical device in the NFV system where a logical function module capable of executing the method flow that the first node can execute is located, The physical device may be independently installed in the physical device of the first node, or may be a physical device capable of communicating with the physical device of the first node. The device may also be presented in the form of a chip, where the chip carries an application program capable of implementing the method flow that the first node can execute.

[0366] The means for releasing the connection may include:

[0367] The determining unit 10 is configured to determine a second...

Abstract

Provided are a connection release method, device and system, which relate to the technical field of communications and can enable a node to reasonably release a connection which has been established between same and other nodes. The method comprises: a first node determines from a plurality of second nodes a second node which is allowed to release a connection and deletes information about the second node which is allowed to release a connection and stored in the first node, wherein the plurality of second nodes are nodes that have established a connection with the first node. The method is applied to an NFV system.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for releasing a connection. Background technique [0002] With the rapid development of virtualization technology, a network function virtualization (English: network function virtualization, abbreviation: NFV) system that implements functions of dedicated network element devices in a network on general-purpose physical devices has gradually attracted people's attention. [0003] In the NFV system, there are network function virtualization orchestrator (English: network function virtualization orchestrator, abbreviation: NFVO), virtual machine infrastructure management node (English: virtualized infrastructure manager, abbreviation: VIM), virtual network function management node (English: virtualized network function manager, VNFM) and virtual network function (English: virtualized network function, abbreviation: VNF) and other functional...
