Abstract

The embodiment of the invention provides a method and device for determining a transmission path, relates to the technical field of communication, and can realize load balancing of a high-guarantee-level service in a network so as to guarantee the service quality of high-guarantee-level service transmission when the network is heavily loaded. The method comprises the following steps: acquiring service information of a to-be-transmitted service; acquiring link state information of all links in the network, wherein the link state information comprises bandwidth information of the links and loadinformation of services of different guarantee levels transmitted on the links; and determining a target transmission path of the to-be-transmitted service according to the service information of theto-be-transmitted service and the link state information in the network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for determining a transmission path. Background technique [0002] During service transmission, it is necessary to determine an appropriate transmission path for the service to be transmitted to ensure smooth service transmission. [0003] With the continuous expansion of application scenarios and the rapid development of network technology, the Internet Protocol (Internet Protocol, IP) network has now become a comprehensive bearer network integrating multiple services such as data, voice, video, and industrial control. The above-mentioned different types of services have very different requirements on network transmission quality (such as delay, bandwidth, delay jitter, and packet loss rate, etc.); in addition, for the same service, different users may also have different requirements for network transmission quality . Due to limited network ...
