Problems solved by technology

[0002] At present, the Internet has the following problems: first, routing is based on the destination IP address and the shortest path, ignoring the requirements of the available link capacity of the network and the packet flow itself, such as some links are overloaded or congested, while other links are under utilization. The bandwidth utilization rate of the entire network link is not high; secondly, the current IP technology hopes to support a wide range of services (such as voice and video, etc.), but the current IP service cannot guarantee the service quality of these services
[0006] In the current traffic engineering solution, since the main function of the router is the IP layer forwarding function, in the above process, only some IP layer indicators (such as link bandwidth) can be negotiated, and the indicators for obtaining links are relatively small, and the final decision The forwarding link of may not be the optimal forwarding link

Abstract

The invention discloses a traffic scheduling method, system and device based on service types. The method includes the steps that a traffic scheduling server obtains the traffic information of various service types needing to be transmitted in a backbone network, and link information of all links in the backbone network is obtained; the traffic scheduling server determines the transmission links of the traffic of various service types in the backbone network according to the traffic information of various service types and the link information of all the links; the traffic scheduling server informs the network devices in the backbone network of the transmission links of the traffic of various service types in the backbone network, and the network devices in the backbone network transmit the traffic of the service types according to the transmission links of the traffic of various service types in the backbone network. Through the traffic scheduling method, system and device based on the service types, the bandwidth utilization rate can be increased, the link bandwidth is allocated as required, service experience is guaranteed, and differentiated traffic scheduling is achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a flow scheduling method, system and equipment based on service type. Background technique [0002] At present, the Internet has the following problems: First, routing is based on the destination IP address and the shortest path, ignoring the requirements of the network’s available link capacity and packet flow itself, such as some links are overloaded or congested, while other links are under utilization. The bandwidth utilization rate of the entire network link is not high; secondly, the current IP technology hopes to support a wide range of services (such as voice and video, etc.), but the current IP service cannot guarantee the service quality of these services. Based on the above problems, IP technology considers adding flow control (or called flow engineering) technology to provide a direct flow control mechanism. [0003] Traffic engineering is used to a...
