Embodiment 1

[0042] In order to solve the problem of high traffic pressure, low utilization rate and low processing efficiency of business nodes deployed in the network when determining the business transmission path, it is proposed to use software-defined network (English: Software Defined Network, abbreviated as : SDN), open flow (English: Open flow) technology and Path Computation Element (English: Path Computation Element, abbreviation: PCE) are applied to the solution for determining the service transmission path. When the service customized by the network user is transmitted in the network, it is not limited to one data packet, usually, it is a continuous data packet, so the service transmitted in the network can also be called a service flow. Through SDN and Open flow technology, flexible and refined definition and distinction of service flows (English: flow), SDN controller or PCE can flexibly and dynamically control the behavior of forwarding service flows of each network node acco...

Embodiment 2

[0080] based on figure 2 As shown in the system architecture, Embodiment 2 of the present invention proposes a method for determining a service transmission path, such as Figure 5 As shown, the specific processing flow of the method is as follows:

[0081] Step 50, the client determines the service chain object when the service is transmitted in the network.

[0082] The service chain object may include the service processing capabilities that need to be provided by the service nodes when transmitting services in the network, and may also include the processing priority corresponding to the service processing capabilities that need to be provided by the service nodes.

[0083] Step 51, the client sends the determined service chain object to the server based on the extended PCEP.

[0084] The client can send a path calculation request message containing the service chain object to the server based on the extended PCEP.

[0085] In the technical solution proposed by Embodim...

Embodiment 3

[0110] Embodiment 3 of the present invention proposes a device for determining a service transmission path, such as Figure 6 shown, including:

[0111] The receiving unit 601 is configured to receive the service chain object sent by the client based on the extended path computation unit communication protocol PCEP, and transmit the service chain object to the determination unit 602, and the service chain object includes The business processing capability provided by the business node is required.

[0112] The determining unit 602 is configured to obtain the service chain object transmitted by the receiving unit 601, and determine at least one service chain object in the network that matches the service chain object according to the service processing capability that the service node can provide in the pre-stored service node attribute information. The service node transmits the determined service node to the service transmission path generation unit 603 .

[0113] The servi...

Abstract

Disclosed are a service transmission path determination method, device and system, the method comprising: receiving a service chaining object sent by a client based on the extended path computation element communication protocol (PCEP), the service chaining object comprising service processing capacity requiring provision by a service node during service transmission on a network; according to the service processing capacity provided by the service node in the prestored service node property information, determining at least one service node matching the service chaining object on the network; and generating a service transmission path based on the determined service node to transmit the service initiated by the client. The present invention can effectively solve the problems of high traffic load and low traffic utilization on a service node deployed on a network.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, device and system for determining a service transmission path. Background technique [0002] Usually, various service nodes are deployed in a service center or at a network edge service provision point (English: Point of Presence, abbreviation: PoP) provided by a network operator. Service nodes refer to nodes with different functions that can provide network users with 4-7 layer service processing capabilities. When the services transmitted in the network are processed, they need to pass through various deployed service nodes in a certain order. [0003] Such as figure 1 As shown, network users such as figure 1 The shown network user A) needs to customize network services to the server (which may be provided by the network operator), and then transmit the services according to the customized network services. Since the service nodes in the netw...
