Description

Method and device for deploying and generating parameters and files in virtual network
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for deploying and generating parameters and files in a virtual network.
Background
Network element functions in an NFV (Network Function Virtualization) system are provided in a software implementation manner running in virtual resources, and by this means, the NFV system can run multiple Network elements simultaneously to provide different services, which not only improves the utilization efficiency of resources, but also improves the flexibility of the Network system.
When a Virtual machine is deployed in an NFV system, in the prior art, a Virtual network port of the Virtual machine is associated with a physical network port through a VSwitch (Virtual Switch), but when determining a physical network port to which a Virtual network port needs to be associated, the VSwitch performs Hash operation on an IP (Internet Protocol ) address of the Virtual network port to obtain a Hash result, and a result obtained by modulo the Hash result on the total number of the physical network ports is a number that needs to be associated with the physical network port, and then associates the Virtual network port with the physical network port corresponding to the number. In this way, it may occur that different virtual ports are associated to the same physical port. Therefore, if the communication quality of the logical plane where the currently communicating virtual port is located is degraded (for example, a packet drop or a packet error occurs during communication through the logical plane), the virtual port belonging to another logical plane will be switched to another logical plane for communication, however, since the virtual port belonging to another logical plane may be the same physical port as the physical port associated with the currently communicating virtual port, the switching of the logical plane will not improve the current communication quality.
In order to separate the logical planes, different virtual network ports are respectively associated with different physical network ports by a manual configuration mode at present, but the mode of associating the virtual network ports with the physical network ports is complex.

Detailed Description
Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The embodiment of the present application is applied to the NFV system 10 shown in fig. 1, where the NFV system 10 may be applied to various networks, such as a data center network, an operator network, or a local area network.
Specifically, the NFV System 10 includes an NFV-MANO (NFV Management and organization) 101, an NFVI (NFV Infrastructure layer) 130, at least one VNF (virtual network Function) 108, at least one EM (Element Management) 122, an OSS/BSS (Operation-Support System/Business Support System) 124, and a network service, a VNF, and an Infrastructure description 126. Among other things, the NFV-MANO101 includes an NFVO (NFV orchestrator) 102, at least one VNFM (VNF Manager) 104, and a VIM (Virtualized Infrastructure Manager) 106.
It should be noted that the network services, VNF and infrastructure description 126, and the specific functions of the OSS/BSS124 are described in ETSI GS NFV 002V1.1.1 standard.
NFVO102 may implement Network services (e.g., L (L layer) 2, L3 VPN (Virtual Private Network) services) on NFVI130, may also perform resource-related requests from one or more VNFMs 104, send configuration information to VNFMs 104, and collect status information of VNFs 108. additionally, NFVO102 may communicate with a VIM to implement allocation and/or reservation of resources, and exchange configuration and status information of virtualized hardware resources.
NFVI130 includes a virtual resource layer, a virtualization layer, and a hardware resource layer, where the virtual resource layer includes: virtual computing 110, virtual storage 118, and virtual network 120, the hardware resource layer including computing hardware 112, storage hardware 114, and network hardware 116; the hardware resource layer and the virtualization layer are used to provide virtualized resources, e.g., as virtual machines and other forms of virtual containers, for implementing VNF 108. It should be understood that the computing hardware 112 may be commercially available hardware and/or custom hardware to provide processing and computing resources; the storage hardware 114 may be increased storage capacity within the network or storage capacity residing on the storage hardware 114 itself (local storage located within the server); the resources of the computing hardware 112 and the storage hardware 114 may be centralized. The network hardware 116 may span multiple domains and may include devices in a network interconnected by one or more transport networks. The virtualization layer may abstract the hardware resource layer as a virtual resource layer to provide virtualized resources to VNF 108. Virtual computing 110 and Virtual storage 118 may be provided to VNF108 in the form of Virtual machines, and/or other Virtual containers, and in particular implementations, one or more VNFs may be deployed on one VM (Virtual Machine). The virtualization layer abstracts the Network hardware 116 to form a virtual Network 120, and the virtual Network 120 may include a VS (virtual switch) for connecting VMs in the NFV system 10, and the transport Network in the Network hardware 116 may be virtualized using a centralized control plane and a single forwarding plane (e.g., SDN (Software Defined Network)).

Step 202, the third device numbers each virtual network port in each group of virtual network ports, wherein the numbers of the virtual network ports belonging to the same group are different.
Step 203, the third device determines at least one anti-affinity parameter for the number of each virtual port in each virtual port belonging to the same group, where each anti-affinity parameter in the at least one anti-affinity parameter is used to indicate a logical plane to which one virtual port in the at least one virtual port belongs.
Step 204, the third device generates a first file according to the determined at least one inverse affinity parameter set, where the first file includes at least one logical plane set and at least one inverse affinity parameter.
In step 205, the second device obtains the first file.
Step 206, the second device determines the number of at least one virtual network port and the total number of virtual network ports of the same logical plane set belonging to the logical plane according to the at least one logical plane set and the at least one inverse affinity parameter;
step 207, the second device determines at least one parameter set group according to the number of at least one virtual network port and the total number of virtual network ports of the same logic plane set of each belonging logic plane; each parameter set group comprises at least one parameter set, each parameter set comprises a first parameter and a second parameter respectively, the first parameter is used for indicating the number of one virtual network port, the second parameter is used for indicating the position of an effective value in the first parameter which belongs to the same parameter set with the second parameter, the logic planes to which the virtual network ports corresponding to the numbers indicated by the first parameters belonging to the same parameter set group belong are of the same service type, and the numbers indicated by the first parameters belonging to the same parameter set group are different.
In step 208, the second device transmits at least one parameter set group.
