Abstract

The invention discloses dynamic bandwidth allocation method, equipment and system of a multi-service transport network. The method comprises the following steps: obtaining bandwidth request information of T-CONT frames of all transmission containers in a data frame for transmitting multi-type services; allocating the bandwidth of all T-CONT frames according to the bandwidth request information andthe set bandwidth allocation algorithm; and sending the bandwidth allocation information to nodes in the multi-service transport network. By using the invention, different types of services can sharethe channel bandwidth, the bandwidth utilization ratio is improved, and the service quality is ensured.

Description

technical field [0001] The invention relates to data communication technology, in particular to a dynamic bandwidth allocation method, equipment and system of a multi-service transmission network. Background technique [0002] With the development of network communication technology, existing networks can carry various services, such as voice, video, online games, and web browsing. In recent years, the demand for network bandwidth has grown exponentially. Although operators have improved the ability of the network to carry and transmit data through continuous expansion of physical bandwidth and related technologies, the increase in physical bandwidth always lags behind the user's requirements for data transmission. Under the impact of large data volume, how to ensure the reliability of the transmission of various services carried by the network and the QoS (Quality of Service, Quality of Service) of the corresponding services have been carried out, and a lot of research work...
