Embodiment 1

[0159] In the current NFV architecture, the decision-making of VNF expansion and contraction only considers the use of virtual resources, and there is no clear strategy for the service allocation after VNF expansion and contraction. When specific service network elements are deployed in the NFV system, the service The expansion and contraction of network elements cannot be synchronized with the service usage, nor can real service sharing be achieved. In view of this, an embodiment of the present invention provides a method for expanding and contracting a service VNF, which is applied to an upper-level server in an NFV system. Such as figure 2 As shown, the method includes:

[0160] Step S201, obtaining monitoring index data, the monitoring index data includes dynamic monitoring index data that changes in real time and static monitoring index data that changes in non-real time;

[0161] When it is determined to add or delete business data, or when it is determined to reach t...

Embodiment 2

[0194] refer to Figure 5 , which is a flowchart of a method for expanding and contracting a service VNF provided by an embodiment of the present invention, specifically includes the following steps:

[0195] Step S501, monitoring system time or system service changes;

[0196] The upper-level server monitors the system time to determine whether the preset expansion and contraction detection cycle has been reached.

[0197] The SDNC server monitors the system service changes to determine whether to add or delete services.

[0198] Step S502, the SDNC server determines whether to add new services, if so, execute step S503, otherwise execute step S504;

[0199] Step S503, the SDNC server performs service distribution according to the service distribution rules indicated by the superior server, and distributes the newly added service to the corresponding VNFC;

[0200] The upper-level server sends the determined service distribution strategy to the SDNC server. After receiving...

Embodiment 3

[0235] A method for expanding and contracting a service VNF in the present invention is described above, and a device for implementing the method for expanding and contracting a service VNF is described below.

[0236] see Figure 7 , an embodiment of the present invention provides a device for expanding and contracting a service VNF, which is applied to an upper-level server in an NFV system, including:

[0237] The indicator monitoring module 701 is used to obtain monitoring indicator data, and the monitoring indicator data includes dynamic monitoring indicator data that changes in real time and static monitoring indicator data that changes in non-real time;

[0238] The expansion and contraction decision module 702 is used to determine whether to expand or shrink the capacity when the static monitoring index data meets the preset requirements, otherwise, determine whether to expand the capacity according to the dynamic monitoring index data;

[0239] The capacity expansion...

Abstract

The invention provides a capacity expansion and shrinkage method and equipment for a service virtual network function VNF, and the equipment comprises the steps: obtaining monitoring index data whichcomprises dynamic monitoring index data changing in real time and static monitoring index data changing in non-real time; when it is determined that the static monitoring index data meets a preset requirement, determining capacity expansion or capacity reduction, and otherwise, determining whether capacity expansion is performed or not according to the dynamic monitoring index data; and when it isdetermined that capacity expansion or capacity reduction is performed, sending an instruction to a management and network orchestration MANO server to instruct the MANO server to perform capacity expansion or capacity reduction. According to the capacity expansion and shrinkage method and device for the service virtual network function VNF provided by the invention, the problem that an existing capacity expansion and shrinkage method for the service VNF is inaccurate in capacity expansion and shrinkage decision and causes resource waste or overweight system load is solved.

Description

technical field [0001] The invention relates to a network function virtualization technology, in particular to a method and equipment for expanding and contracting a service virtual network function (VNF). Background technique [0002] With the development of communication technology and network technology, SDN (Software Defined Network, software defined network) technology and NFV (Network Function Virtualization, network function virtualization) technology are gradually integrated in the telecommunications network architecture, forming SDNFV (Software Defined Network Function Virtualization , software-defined network function virtualization) technology. The telecom network is transitioning from a dedicated network composed of hardware devices to an intelligent network based on SDNFV technology. SDN technology centrally manages the control logic applied in the network, facilitates the management and configuration of the network and the deployment of new protocols, and impr...
