Network real-time scheduling method based on service types

The invention discloses a network real-time scheduling method based on service types. The method comprises the following steps: S1, judging whether total network bandwidth is greater than total transmission bandwidth demand of data packets in all sessions, if so, directly using a bandwidth iterative allocation model to perform bandwidth allocation and executing a step S3, otherwise, executing a step S2; S2, judging whether each session belongs to a real-time service, directly using the bandwidth iterative allocation model to perform bandwidth allocation for the session belonging to the real-time service, and performing bandwidth allocation for the sessions belonging to a non-real-time service through a bandwidth balancing iterative allocation model; and executing the step S3; S3, acquiringvirtual completion time of each session, sending data packets in the session according to an ascending order of the virtual completion time, and realizing network real-time scheduling.
