Embodiment 1

[0052] For ease of understanding, see figure 1 , Embodiment 1 of a VNF deployment method oriented to energy saving and QoS guarantee provided by the present application, including:

[0053] Step 101: Connect the VNF instances mapped according to the preset SFCs to be deployed through the first K shortest path algorithm to obtain an initial VNF deployment scheme.

[0054] It should be noted that the preset SFC to be deployed can be a virtual network request obtained directly or a simulated virtual network request. The specific source can be given according to the actual situation and is not limited. The K shortest path algorithm is used for The method of finding the shortest path between the deviation node and the termination node, starting from a certain node, along the path formed by the node and the node to reach another node, the path with the smallest sum of weights on each edge is called The shortest path; the specific K shortest path algorithm is used for the connection...

Embodiment 2

[0066] For ease of understanding, see figure 2 , the embodiment of the present application provides a second embodiment of a VNF deployment method oriented to energy saving and QoS guarantee, including:

[0067] Step 201: Receive a virtual network request simulated using a preset Poisson distribution, and the virtual network request includes multiple SFCs to be deployed.

[0068] It should be noted that the Poisson distribution is suitable for describing the number of occurrences of random events per unit time (or space); for example, the number of virtual network requests per unit time in this embodiment provides a source for virtual network requests, and random simulation is more capable Respond to actual virtual network requests.

[0069] Step 202: Map each preset to-be-deployed SFC according to the preset deployment rule to obtain a VNF instance. The preset deployment rule is to update the availability of network resources for each deployed preset to-be-deployed SFC.

Abstract

The invention discloses a VNF deployment method and device for energy saving and QoS guarantee. The method comprises the following steps: performing connection deployment on VNF instances mapped by apreset to-be-deployed SFC through K shortest path algorithms, and on the basis, calculating a fitness function value of each initial VNF deployment scheme by adopting a multi-objective optimization model; selecting a preset initial VNF deployment scheme corresponding to the first half of the smaller fitness function value as a parent population; performing operation through a genetic algorithm toobtain a filial generation population; updating and deploying according to constraint conditions and K shortest path algorithms; judging whether the number of iterations is greater than the preset maximum number of iterations or not, and if not, continuing iteration until the number of iterations is the preset maximum number of iterations. The technical problem that QoS cannot be guaranteed and energy consumption cannot be saved in the VNF deployment process in the prior art is solved.

Description

technical field [0001] The present application relates to the communication field, in particular to a VNF deployment method and device for energy saving and QoS guarantee. Background technique [0002] NFV (Network Function Virtualization) is a new concept promoted by the European Telecommunications Standards Institute, which aims to simplify the deployment and management of network services by using virtualization and cloud computing technologies. Compared with the traditional service provision mode based on hardware devices, NFV network supports the deployment of VNF (virtual network architecture) on general servers, so this technology reduces the overhead of deploying dedicated hardware devices while ensuring the flexibility of network services. reliability and scalability. In addition, some VNFs deployed in the network can be connected into a service function chain (Service Function Chain, SFC), and then more complex services can be provided to users. [0003] In a lar...
