Embodiment 1

[0109] When the above SF is load balancing, dynamically create a load balancer (Load Balancing, LB for short) according to SFC usage scheme 1:

[0110] Figure 12 is a schematic diagram of an SFC including a load balancing node according to an embodiment of the present invention, such as Figure 12 As shown in Option 1, SF with load balancing function is automatically deployed according to SFC to provide load balancing for back-end service servers. The load balancing service is implemented based on Nginx, but it is not limited to Nginx, and the load balancing products with high performance are applicable to the present invention.

[0111] According to the planned SFC, the resource management system automatically creates and deploys the load balancing SF as follows:

[0112] Step 1. The service capability of business applications on the application plane needs to be greatly improved. This puts forward the demand for load balancing services for SDN. It is required to build a l...

Embodiment 2

[0118] When the above SF is a firewall, dynamically create a firewall (FireWall, FW for short) according to SFC usage scheme 1:

[0119] Figure 13 is a schematic diagram of an SFC including a firewall according to an embodiment of the present invention, such as Figure 13 As shown in Figure 1, plan one is used to automatically deploy SF with firewall functions based on SFC to provide security protection for the back-end service network.

[0120] According to the planned SFC, the resource management system automatically creates and deploys the firewall SF as follows:

[0121] Step 1. The application plane puts forward requirements on the security of the service network of the service application, and it is necessary to build a firewall to provide security protection for the service network.

[0122] Step 2. The requirement planning of the application plane service application includes the SFC of the firewall SF, such as Figure 13 shown. In SFC, the public IP of the manage...

Embodiment 3

[0127] When the aforementioned SF is a virtual private network (Virtual Private Network, VPN for short), according to the second SFC usage scheme, a VPN is dynamically created to provide VPN services for the network.

[0128] According to the planned SFC, the resource management system automatically creates and deploys VPNs as follows:

[0129] Step 1. The application plane puts forward requirements on the business network of business applications, and needs to build a VPN to provide VPN services for the business network.

[0130] Step 2. The application plane plans the SFC including the VPN function according to the requirements of business applications. In SFC, the public IP address of the management network can be 10.46.178.0 / 24, the IP address of the business network vxlan can be 192.168.168.0 / 24, router interface settings, etc., and the SFC-related information is passed to the control plane through the A-CPI interface . In this scenario, the resource indication informat...

Abstract

The present invention provides a method and device for deploying a service function SF, wherein the method includes: obtaining predetermined network function virtualization NFV information, wherein the NFV information includes information used to indicate the underlying network resources required to establish network functions Resource indication information, and function indication information used to indicate the service function SF deployed on the underlying network resource; create an underlying network resource according to the above resource indication information and function indication information, and deploy SF on the underlying network resource. Through the present invention, the problems existing in related technologies that require manual intervention to create bottom network resources and deploy SFs, resulting in the rigidity of group creation of bottom network resources and deployment of SFs, and the inability to flexibly adjust bottom network resources and SFs, thus achieving flexible adjustments Effects of underlying network resources and SF.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for deploying a service function SF. Background technique [0002] In a network function virtualization (Network Function Virtualization, NFV for short) technology, general-purpose hardware such as x86 and a virtualization technology can be used to carry software processing of many functions. Thereby reducing the expensive equipment cost of the network. Through software and hardware decoupling and functional abstraction, network device functions no longer depend on dedicated hardware, resources can be fully and flexibly shared, and rapid development and deployment of new services can be realized, and automatic deployment, elastic scaling, and fault isolation can be performed based on actual business needs and self-healing etc. [0003] A service function chain (SFC for short) is an ordered collection of service functions, which performs a series of service...
