Embodiment 1
[0044] In this embodiment, a call implementation method is provided, Figure 4 is a flowchart of a data processing method according to an embodiment of the present invention, such as Figure 4 As shown, the process includes the following steps:
[0045] Step S402, the classifier acquires part or all of the metadata in the message corresponding to the upper-layer service function chain SFC;
[0046] Step S404, the classifier copies the part or all of the metadata to the metadata field corresponding to the lower SFC.
[0047]Through the above steps, some or all of the metadata corresponding to the upper-layer SFC is copied to the metadata field corresponding to the lower-layer SFC, and then the metadata of the lower-layer SFC can be directly analyzed and processed. The processing of the two-layer SFC header adopts the above technical solution to solve the problem that in the related technology, the existing technology cannot realize that the SF can recognize the two-layer SFC ...
Embodiment 2
[0062] In this embodiment, a data processing device is also provided, which is applied to a classifier. The device is used to realize the above-mentioned embodiments and preferred implementation modes, and those that have already been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.
[0063] Figure 5 is a structural block diagram of a data processing device according to an embodiment of the present invention, such as Figure 5 Shown:
[0064] An acquisition module 50, configured to acquire part or all of the metadata in the message corresponding to the upper-layer service function chain SFC;
[0065] The copying module 52 is configured to copy the part or all of the ...
Embodiment 1
[0072] Such as Figure 7 As shown, the source device S sends traffic to the destination device D, and the traffic needs to pass through service function entities SF1, SF2, SF3, and SF4. Each business function here can be an inter-domain SF. The inter-domain SF here is an SFC in the DC network. For the WAN, it can be abstracted as an inter-domain SF. The DC network provides only the abstracted SF to the upper-layer WAN, and the upper-layer network does not care about the path of the SFC inside the DC network.
[0073] When the upper-layer network needs some specific service functions, it can rent some service functions in the DC network, such as DPI, calculation, etc. At this time, what the DC provides to the WAN control plane is only a SF2 of DPI plus calculation. For the WAN , this SF2, like other SF1, also has a SFID2 identifier corresponding to the inter-domain service function of SF2.
[0074] For the control plane of the WAN, what the DC network needs to provide is the...
