Embodiment Construction

[0032] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0033] Such as figure 1 Shown is a schematic diagram of the working principle of the access device. The user terminal is connected to the user port on the service board of the access device through the RTU (Remote Terminal Unit), and the control board on the access device is connected to the video source through the ATM / IP network, and is Management equipment (such as network management system) is connected to realize data service and IP TV service at the same time. In the picture:

[0034] A is the interface from the service board to the user RTU;

[0035] B is the interface from the uplink port of the access device to the video source;

[0036] C is the interface from the access device to the network management system.

[0037] The invention provides a dynamic control method of service bandwidth, which realizes the dynamic control of the bandwidth of...

Abstract

A service bandwidth dynamic control method is applied to an access device. The method comprises: identifying the service type of messages by the access device according to medium access control (MAC) address, or VLAN, or IP message packaging protocol type, further identifying data service and wide band value-added service of users, wherein the access device is connected to ATM / IP network for implementing the data service and the value-added service; the access device identifies the dynamic band width of the users; the access device distinguishes the dynamic band width of the data service and value-added service of the users according to the identification of the service type and the user dynamic band width; when the dynamic band width of the data service of the users and the dynamic band width of the value-added service do not exceed the threshold, the access device dynamically adjusts the band width distribution of the data service and the value-added service to meet the band width requirement of users. The invention implements dynamic band width control of users in the access device.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for dynamically controlling service bandwidth. Background technique [0002] With the development of various broadband value-added services such as online live broadcast, telemedicine, Internet TV, distance education, and real-time video conferencing, the bandwidth requirements of end users are increasing. Network load, but the bandwidth requirements of the access layer network equipment have not been reduced. On the contrary, with the development of various broadband value-added services, the bandwidth requirements of the access layer network equipment are getting higher and higher. How to reasonably satisfy user bandwidth in this way has gradually become a bottleneck of access layer network devices. [0003] CAR (Committed Access Rate) is a bandwidth management technology used to control the transmission rate of IP packets during network congestion. It can limit...
