Traffic scheduling method in real-time transmission mechanism

Abstract

The invention discloses a traffic scheduling method in a real-time transmission mechanism. According to the method, a controller adjusts the forwarding proportion of common service flow according to the current distribution condition of all time-sensitive network slices, and a worst-fit strategy is adopted. In order to avoid congestion when a new flow arrives, a time-sensitive network slice with the maximum residual capacity is selected, and by using the effective scheduling method, convection control can be realized, and mutual influence between different types of flows can be avoided.

Description

technical field [0001] The invention belongs to the technical field of network communication, and in particular relates to a flow scheduling method in a real-time transmission mechanism. Background technique [0002] The traditional IP network provides a best-effort single service model, does not make a clear distinction on the business type of the flow, and allocates bandwidth equally between the flow and the flow. The non-real-time flow mainly transmitting data in the early network is not affected by this. Impact of service model. With more and more IP network applications, the network must not only guarantee bandwidth but also strictly limit delay and packet loss rate. Therefore, traditional service methods cannot guarantee the development needs of IP networks. [0003] In a traditional circuit-switched network, it is easy for a certain flow to occupy resources alone, resulting in a low utilization rate of network resources. Service flows with different QOS requirements...

Problems solved by technology

With more and more IP network applications, the network not only needs to guarantee the bandwidth but also needs to strictly limit the delay, packet loss rate, etc., so the traditional service method cannot guarantee the development needs of the IP network

[0003] In traditional circuit switched networks, it is easy to cause a certain flow to occupy resources alone, which makes the utilization of network resources low.
