Problems solved by technology

However, when a node receives an NSH packet with a context header, it does not know how to parse the context header. Whether to parse the context header as context data of the data center scene or as a mobile Should the context data of the scene be parsed, or should it be parsed as context data in other scenes? If the parsing is wrong, the context data information cannot be read correctly, resulting in business processing failure

Embodiment 1

[0078] like Figure 11 As shown, the service function chain SFC1 inside the data center is SF2->SF5; where SF1 and SF2 are connected to SFF1 / TOR (Top-of-Rack, set-top switch) 1, SF3 is connected to SFF2 / TOR2, and SF4 and SF5 are connected To SFF3 / TOR3; that is, the service forwarding path experienced by the service function chain is SFP1: SFF1->SF2>SFF3->SF5.

[0079] When the message arrives at the gateway device in the data center, the gateway device, as the Classifier in the service function chain technology, classifies the message and finds that the message forwarding corresponds to the service chain SFC1, that is, the corresponding service forwarding path is SFP1, then the message forwarding process as follows:

[0080] Step 101: The Classifier node classifies and discovers, and obtains the enhanced context data header type. The traffic needs to enter the data center for processing, and then obtains the relevant information of the service forwarding path and the context ...

Embodiment 2

[0088] like Figure 12 As shown, the service function chain SFC2 in the mobile scenario is SF2->SF5; where SF1 and SF2 are connected to SFF1, SF3 is connected to SFF2, and SF4 and SF5 are connected to SFF3; that is, the service forwarding path experienced by the service function chain is SFP2 : SFF1->SF2>SFF3->SF5.

[0089] When the message arrives at the mobile network gateway device (P-GW), the gateway device, as a Classifier in the service function chain technology, classifies the message and finds that the message forwarding corresponds to the service chain SFC2, that is, the corresponding service forwarding path is SFP2, then The message forwarding process is as follows:

[0090] Step 201: The Classifier node classifies and discovers, and obtains the enhanced context data header type. The traffic needs to enter the mobile network data center for processing, and then obtains the relevant information of the service forwarding path and the context data header information be...

Embodiment 3

[0098] like Figure 13 As shown, for data traffic that needs to go through the broadband network and then enter the data center, the service function chain SFC3 is SF2->SF3->SF5; where SF1 and SF2 are connected to SFF1, which belong to the broadband network domain, and SF3 is connected to SFF2, SF4 and SF5 is connected to SFF3, which is in the data center network domain; that is, the service forwarding path experienced by this service function chain is SFP3: SFF1->SF2->SFF2->SF3->SFF3->SF5. On SFF2, reclassification will occur, and the subsequent new service forwarding path is SFP4: SFF1->SF2->SFF2->SF3->SFF3->SF4;

[0099] When the message arrives at the broadband network device (BNG), the gateway device, as the Classifier in the service function chain technology, classifies the message and finds that the message forwarding corresponds to the service chain SFC3, that is, the corresponding service forwarding path is SFP3. The forwarding process is as follows:

Abstract

The invention provides a data message processing method and device. The method comprises the steps that an enhanced context header type is acquired; the enhanced context header type is packaged in a network service header and the network service header is packaged in a data message; and the data message is transmitted along a service forwarding path. With application of the data message processing method and device, a context header type identifier can be further increased in an SFC network so as to enhance further identification for the context header on nodes supporting a service chain.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for processing data messages. Background technique [0002] At present, a Service Function Chain (SFC) technology is proposed, which integrates all services, virtualizes the Service overlay (service coverage) layer, forms its own service topology, and decouples it from the underlying network. Restricted by the underlying network structure, architecture such as figure 1 shown. It can be seen that the SFC technology includes the following components: Classifier, Service Function Forwarder (SFF for short), Service Function (SF for short), and Network Service Header Proxy (SFF for short). NSH Proxy). Among them, the Classifier is responsible for classifying the traffic, and encapsulating the traffic with a Network Service Header (NSH for short) according to the classification results, that is, determining the subsequent service function path of the message on the Clas...
