Problems solved by technology
[0004] In the above process of load sharing, it is necessary for the control node to pre-program all segment routing strategies. When the number of business functions included in the service chain is relatively large, and each business function corresponds to a large number of virtual resource modules, all routing strategies must be programmed. Segment Routing Policies Are Very Inefficient
In addition, all packets are distributed according to the determined segment routing strategy at the entry node of the service chain, resulting in a greater pressure on the entry node of the service chain
In addition, when the configured virtual resource module corresponding to a certain business function changes, the control node needs to rearrange all the segment routing policies, which makes the process of processing packets more complicated.

The invention discloses a service message forwarding method and device and a computer storage medium and belongs to the technical field of routing. The method comprises steps that when a first SFF receives a message sent by any second virtual resource module connected with the first SFF, a forwarding path of the message is dynamically determined according to configuration information of the second virtual resource module realizing a second service function so that dynamic load sharing of the message is realized; and load sharing is not carried out uniformly by the service chain inlet node so that the pressure of the service chain inlet node is reduced. Besides, even if the virtual resource module configured for the second service function changes, the first SFF can dynamically share the load only by updating the configuration information of the second virtual resource module in time, and the control node does not need to rearrange all segment routing strategies so that the processing process in the scene is simplified.
Description
technical field [0001] The present application relates to the technical field of routing, in particular to a service message forwarding method, device and computer storage medium. Background technique [0002] When the message is transmitted in the network, in order to provide users with safe, fast and stable network services, it is necessary to sequentially process the message according to the multiple service functions (service function, SF) included in the configured service function chain. These multiple service functions may include service functions such as traffic cleaning, deep packet inspection, and network acceleration. For any business function, multiple virtual resource modules for realizing the business function can be configured correspondingly. When a message needs to be processed according to the business function, the message is distributed to each virtual resource module, and each virtual resource module follows the Service functions process some received ...
