Embodiment Construction

[0057] The technical solution in this application will be described below with reference to the accompanying drawings.

[0058] In order to facilitate understanding and explanation, the passive optical network (passive optical network, PON) will be described as a specific application scenario, such as figure 1 As shown, a plurality of optical network units (optical network unit, ONU) is connected with a plurality of user equipments in the customer premises network, and a plurality of ONUs are connected to the optical fiber and the optical coupler through the optical distribution network (optical distribution network, ODU) The line terminal (optical line terminal, OLT) sends a bandwidth request message, and the OLT receives the bandwidth request message sent by multiple ONUs and allocates bandwidth information to each ONU. Each ONU sends an upstream message on the allocated bandwidth information, and the OLT receives An uplink message sent by the ONU, and sends the uplink messa...

Abstract

The invention provides a dynamic bandwidth allocation method and related equipment. The method comprises the following steps of: by dynamic bandwidth allocation equipment, receiving a bandwidth request message from bandwidth request equipment by at least two access ports of aggregation equipment, wherein the bandwidth request message comprises requested bandwidth information, allocating bandwidthinformation to the bandwidth request equipment according to the bandwidth information and the residual bandwidth information of an uplink output port of the aggregation equipment, wherein the residualbandwidth information is the difference between the limited bandwidth information of the uplink output port and the allocated bandwidth information, and sending a response message to the bandwidth request equipment through an access port. According to the method, the bandwidth request messages sent by all the bandwidth request equipment can be globally scheduled, the bandwidth information is globally and dynamically allocated, and the problems of uplink congestion and packet loss in the system and high power consumption cost of the devices are avoided.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a dynamic bandwidth allocation method and related equipment. Background technique [0002] With the rapid development and innovation of Internet technology, users have increasingly diverse demands on Internet information, which requires the access network to be able to meet users' large-bandwidth access and multi-service quality of service. As a high-speed bandwidth access technology, passive optical network (PON) has developed rapidly. PON system generally consists of optical line terminal (optical line terminal, OLT), optical network unit (optical network unit, ONU) and optical distribution network (optical distribution network, ODU) composition. [0003] Cable network is a network based on cable TV network. Cable access is a network access technology based on cable TV (community antenna television, CATV) network. It is developed with the expansion of netw...
