A method and device for load distribution

Abstract

The invention discloses a load distribution method and device, belonging to the technical field of computers. The method includes: after the target session is established, the codec server receives a message corresponding to the target session within a preset time period, and performs codec processing on the received message; the codec server determines that the preset Set the first average message processing time of the target session within the duration; the codec server determines the first average message processing time corresponding to the first average message processing time according to the corresponding relationship between the pre-stored average message processing time and the virtual server group The target virtual server group; when receiving the subsequent message of the target session, the codec server assigns the subsequent message of the target session to the target virtual server group for codec processing. By adopting the present invention, it is possible to avoid the situation that the session with relatively low codec algorithm complexity cannot be carried out normally.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a load distribution method and device. Background technique [0002] With the development of NFV (Network Function Virtualization, network function virtualization) technology, the application of NFV becomes more and more extensive, and its functions become more and more powerful, among which, the codec function is one of the important functions. When the user communicates through the terminal, the encoding algorithms used by the two communication parties are usually different. Therefore, after the sender sends communication data (such as voice data or video data) to the NFV system, the NFV system needs to encode the communication data (such as voice data or video data). data) to perform encoding and decoding processing, and convert the communication data into communication data that can be recognized by the receiver. [0003] Multiple applications may be installed in the NF...

Problems solved by technology

[0005] In practice, different sessions use different codec algorithms. Sessions with high codec algorithm complexity (such as video sessions) and sessions with long packet processing time and low codec algorithm complexity (such as voice sessions) The packet processing time is relatively short. Therefore, based on the above processing, when the virtual server processes packets one by one, there will be packets of sessions with high codec algorithm complexity, occupying the sessions of low codec algorithm complexity. Packet processing resources lead to situations where sessions with low codec algorithm complexity cannot be carried out normally. For example, the virtual server is currently processing packets of video sessions. Due to the long processing time, packets of voice sessions in the task queue will be If the delay is too long and the voice session is interrupted
