Method and system for distributing dynamically bandwidth resource

Abstract

The invention discloses a dynamic bandwidth resource allocation method and system, which considers the differences of brandwith, time delay, priority level in different business, ensures the service quality of business, solves contradictions between the efficient use of brandwith and the service quality more efficiently, at the same time sloves the problem of the uniform DBA scheduling mechanism in diversified user terminal, and meets the service quality request of 'three nets in one'.

Description

technical field [0001] The present invention relates to the technical field of Dynamic Bandwidth Assignment (DBA, Dynamic Bandwidth Assignment), in particular to a dynamic bandwidth resource assignment method and system. Background technique [0002] Passive Optical Network (PON) technology has been standardized at present with three protocols: Ethernet Passive Optical Network (EPON), Broadband Passive Optical Network (BPON) and Gigabit Passive Optical Network (GPON). It can provide users with greater bandwidth and operators with greater coverage, and because the cost of optical devices and optical fibers has gradually decreased in recent years, passive optical networks have been more and more widely used. No matter what kind of passive optical network, their network structure and working principle are similar. [0003] Referring to Figure 1, the passive optical network is composed of optical terminal equipment (ONT), optical line equipment (OLT) and passive distribution ne...

AI Technical Summary

Problems solved by technology

The stateless reporting method focuses on the principle of fairness, while the status reporting method focuses on the principle of on-demand allocation. However, neither method takes into account the differences in requirements for bandwidth, delay, and priority among services.

Unable to meet the service quality requirements of "triple play"

[0010] With the development of technology, the trend of "three-in-one" is becoming more and more obvious. Although the passive optical network also complies with the high bandwidth requirements of this trend, the service quality of "three-in-one" for different services There are higher requirements, and the existing DBA mechanism (regardless of the implementation method) cannot guarantee the quality of the service when faced with increasingly complex quality of service (QoS) requirements. How to make the passive optical network effectively guarantee the service QoS is the key to the success of passive optical network

[0011] Although the above description is for passive optical networks, similar problems exist in the DBA mechanism for other networks suitable for shared media, such as WiMAX networks and WLAN networks.
