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.

Embodiment

[0059] In order to facilitate the understanding and implementation of the present invention by those skilled in the art, the technical solutions of the present invention will now be further described with reference to the accompanying drawings, and a specific implementation manner of the present invention will be given.

[0060] Ordinary service traffic has a relatively low demand for QoS and is not sensitive to delay. Therefore, during construction, the transmission path of the source and destination nodes is planned according to the load conditions of each node, and the network throughput is improved as much as possible, and multi-path forwarding is used for transmission. normal business flow. K-shortest paths (k-shortest paths, KSP) is a commonly used method when selecting a path with the least number of nodes in the forwarding process. According to the conditions of the path, it can be divided into two types: general KSP and limited acyclic. The present invention The path ...

Abstract

The invention discloses a flow scheduling method in a real-time transmission mechanism. In the present invention, the controller adjusts the forwarding ratio of common service flows according to the current allocation of all time-sensitive network slices, and adopts a worst-fit strategy to schedule time-sensitive flows, that is, when new traffic On arrival, to avoid congestion, we choose a time-sensitive network slice with the largest remaining capacity. Using this efficient scheduling method can control the flow and avoid the interaction between different kinds of flows.

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 single best-effort service mode, without a clear distinction between the types of flow services, and the equal allocation of bandwidth between flows. The impact of service models. With the increasing number of IP network applications, the network not only needs to guarantee the bandwidth but also strictly limits the delay and packet loss rate. Therefore, the traditional service mode cannot guarantee the development requirements of the IP network. [0003] In traditional circuit-switched networks, it is easy for a certain flow to occupy resources alone, resulting in low utilization of network resources. Service flows with different QoS requirements in the IP network share network resources, resulting in the preemption of th...
