Problems solved by technology

This method is simple to implement, but due to the static allocation of bandwidth, on the one hand, the efficiency of bandwidth usage is low; on the other hand, due to the randomness of user service selection, it cannot meet the dynamic needs of user bandwidth.
[0005] In addition, the Resource Reservation Protocol (RSVP, Resource ReServation Protocol) used on the Internet is complex to implement and relies on routing tables, making it difficult to meet the requirements for Layer 2 devices without routing tables such as MODEMs and DSLAMs.
In addition, RSVP is based on an end-to-end signaling protocol. It is necessary to reserve resource soft state information for each flow at each transit node, and it is necessary to periodically refresh this information, resulting in storage overhead and communication. overhead
Finally, due to the scalability problem of RSVP itself, different manufacturers have different compatibility with the protocol, which limits the scalability of the entire system.

Embodiment Construction

[0027] The basic idea of ​​the present invention is to statically configure the service information in the broadband access device. , then, when the bandwidth is adjusted, within the range of the bandwidth owned by the user, the actual bandwidth of the user is dynamically configured. The rate is improved, and the user's own quality of experience is guaranteed.

[0028] The user information includes, but is not limited to: user minimum bandwidth, user maximum bandwidth, protocol type, bandwidth adjustment granularity corresponding to the protocol type, user priority, etc.; service information includes but not limited to, network service type, service occupied bandwidth , Business data packet information. These user information and service information are stored in broadband access equipment, which includes: modems, digital subscriber line modulation multiplexers, broadband remote access servers, routers, aggregation switches, access switches, etc. for bandwidth management con...

Abstract

The invention discloses a method of dynamic bandwidth adjustment in bandwidth access system, which includes the following steps: the bandwidth access equipment is allocated and stored with business information; the bandwidth access equipment monitors and identifies the business information of users' choice in the data packet dispatched; according to the identified business information, the bandwidth access information increases or releases the bandwidth of corresponding users. The invention reduces the update and storage steps of resources reservation soft state, with easier realization. At the same time, the dynamic bandwidth distribution method adopted by the invention can meet the dynamic requirements of users random usage, distribute system bandwidth reasonably to the maximum degree and guarantee the experience quality and service quality of the business used by users.

Description

technical field [0001] The invention relates to the field of broadband access equipment, in particular to a dynamic bandwidth adjustment method in a broadband access system. Background technique [0002] At present, the user's Internet access service has gradually developed from the traditional web browsing application to blogging, video surveillance, video on demand, time-shifted TV on demand and other applications based on video and audio technology. Especially in recent years, with the emergence of comprehensive service services such as Internet TV (IPTV), users' demand for bandwidth has increased sharply, and the demand for bandwidth is related to the way and time of users' use of services. These factors require broadband access. In order to meet the user's dynamic demand for bandwidth, the ingress system adjusts and responds in a timely manner to meet the user's requirements for service quality of experience. [0003] Generally, a broadband access system is composed of...
