Embodiment 1

[0058] See Figure 4 As shown, the message forwarding method provided in this embodiment includes:

[0059] Step 401: The service chain proxy device receives a message with service chain path information; the message comes from the gateway on the SGi / Gi side, or from the previous hop node, specifically, it can be an HTTP URL request message, etc.;

[0060] Step 402: The service chain proxy device adds query information for finding the next-hop path in the user message obtained after processing the message;

[0061] The user message in this step refers to the user message obtained by removing the transport layer information such as the head of the service chain path of the received message by the service chain agent device;

[0062] The query information added in this step is mainly used to search for the next-hop path of the message. The way and / or position of the query information in the message is not modified as long as the service function node meets the requirements; for...

Embodiment 2

[0082] This embodiment provides a service chain proxy device, which can be set in the proxy device, please refer to Figure 5 As shown, the service chain agent device to be served includes:

[0083] The receiving module 1 is used to receive a message with service chain path information; the message comes from the gateway on the SGi / Gi side, or from the previous hop node, specifically, it can be an HTTP URL request message, etc.;

[0084] The processing module 2 is used to add query information for finding the next hop path in the user message obtained after the message is processed; the user message here refers to the service of the message that the service chain agent device will receive The user message obtained by removing the transport layer information such as the header of the chain path;

[0085] The query information added here is mainly used to search for the next hop path of the message. The way and / or position of the query information in the message is set as long ...

Embodiment 3

[0095] In order to better understand the present invention, the present invention will be further illustrated below in conjunction with several specific examples.

Abstract

The invention discloses a message forwarding method, a service chain agent apparatus and an agent device. The service chain agent apparatus, upon receiving a message containing service chain path information, processes the message of a user, adds check information to a user message for checking a next-hop path, transmits the check information to a current object service capacity node; receives the user message processed by the object service capacity node, acquires the check information added previously from the user message, based on the check message, finds a next-hop path, and based on the next-hop path, continuously forwards the user message. According to the invention, the service chain agent apparatus transmits the user message to a corresponding service function node only after adding the check information for finding the next-hop path to the user message, such that the service chain agent apparatus can accurately acquire the next-hop path information based on the check information of the user message even when the original IP and port of the user message are modified by the service function node, and accurately forwards the user message.

Description

technical field [0001] The invention relates to the communication field, in particular to a message forwarding method, a service chain agent device and agent equipment. Background technique [0002] In traditional networks, traffic on the SGi / Gi side needs to pass through all service function (ServiceFunction, SF) nodes, such as figure 1 shown. With the widespread application of mobile terminals such as smart phones, the traffic of mobile networks is increasing rapidly, and the pressure on mobile networks is increasing. Among them, http business accounts for a large proportion. In order to optimize the traffic distribution, it is expected to classify the traffic on the SGi / Gi side, and arrange the traffic path according to the service type, so that the service traffic can only pass through the SF nodes on the path for business processing according to the pre-arranged path. It does not need to go through all SF nodes like in the traditional network. Such as figure 2 sho...
