Embodiment 1

[0060] see figure 1 , figure 1 It is a flowchart of a method for establishing a network service path disclosed in the embodiment of the present application.

[0061] Such as figure 1 As shown, the method includes:

[0062] Step 101: receiving and analyzing the user's service request, the service request includes at least the resource requirements of the service node and the resource requirements of the service link;

[0063] Specifically, the user's service request may include service type, service duration, etc. in addition to the resource requirements of the service node and the service link. Among them, the resource requirements of service nodes include CPU, memory, and hard disk requirements, and the resource requirements of service links include available bandwidth and other requirements.

[0064] Step 102: Calculate the state information of each node and link in the network topology;

[0065] Specifically, the status information here includes available resource stat...

Embodiment 2

[0071] In order to meet the needs of management, we pre-select some nodes in the network topology as network control agent nodes. The network control agent nodes will collect the status information reported by themselves and each node within their management range, and sort out and unify these status information Upload to the upper level node. A node located one level above the network control proxy node may be a management node, which manages all network control proxy nodes.

[0072] Step 102 in the first embodiment can be realized in the following manner:

[0073] see figure 2 , figure 2 It is a flow chart of a method for calculating the state information of each node and link in the network topology disclosed in the embodiment of the present application.

[0074] Such as figure 2 As shown, the method includes:

[0075] Step 201: Calculate the available resource status and service bearer status of each node and link within the management range of each network control...

Embodiment 3

[0079] see image 3 , image 3 It is a flowchart of a method for generating a service path mapping scheme disclosed in the embodiment of the present application.

[0080] The process of step 103 can be realized as follows:

[0081] Step 301: According to the resource requirements of the service node and the resource requirements of the service link, filter the nodes in the network topology to obtain candidate nodes and candidate links;

[0082] Step 302: Evaluate the candidate nodes and the candidate links according to preset criteria and obtain an evaluation result;

[0083] Specifically, the preset criterion includes the amount of available resources, the proportion of services of the same type in the node or the link, and the length of the service path after mapping.

[0084] Step 303: Referring to the evaluation result, determine a target node and a target link from the candidate nodes and the candidate links, and generate a service path mapping scheme.

[0085] Specif...

Abstract

The invention discloses a building method and system for a network service path. The method comprises the steps of receiving a service request of a user and analyzing the service request, obtaining the resource requirements of service nodes and service links in this service request of the user, then calculating status information of each node and each link in a network topology, generating a service path mapping scheme according to the result obtained through calculation, and finally utilizing the generated service path mapping scheme for building the service path. According to the building method for the network service path, the service nodes and the service links can be dynamically determined according to the information of the service request of the user, the resources of the nodes and the links on the finally-generated service path can be better fit in with the requirement of the user, and transmission efficiency is also higher.

Description

technical field [0001] The present application relates to the technical field of network communication systems, and more specifically, to a method and system for establishing a network service path. Background technique [0002] With the continuous growth of the scale of the Internet and the continuous emergence of new network services, the shortcomings of the rigid structure and poor adaptability of the Internet are becoming more and more obvious. actual needs. Therefore, the concept of network development has gradually changed to how to optimize support for network services, such as establishing corresponding optimized transmission paths for carrying specific services. [0003] Therefore, the traditional rigid Internet structure can no longer meet the growing needs of the Internet's basic interconnection and transmission capabilities. There is an urgent need for a solution that can dynamically establish a suitable service path according to the user's service requirements ...
