Bandwidth allocation method, optical line terminator, optical network unit and communication system

Abstract

The present invention discloses a bandwidth allocation methdo, an optical line teminator, an optical network unit and a communication system. The exemplary object of the present invention is to accurately reflect allocation requests and increase the bandwidth use efficiency without requiring expensive and fast integrated circuits or CPUs in the control unit even in a large-scale system with a large number of terminal devices. A subscriber station comprises allocating means for determining bandwidth allocation based on a predetermined allocation condition and bandwidth transmitting means for transmitting bandwidth allocation information determined by the allocating means to an optical line terminator. The optical line terminator comprises pipeline transmitting means for transmitting bandwidth allocation information transmitted from the subscriber stations to all subscriber stations to be allocated with bandwidth.

Description

technical field [0001] The present invention relates to a bandwidth allocation method, an optical line terminator, a subscriber station, a communication system, and a recording medium for recording programs of devices in the system, such as a passive optical network ( Hereinafter referred to as "PON") in which a plurality of devices are connected to an optical line terminal. Background technique [0002] In recent years, due to the rapid popularization of the Internet, broadband access lines have been developed. Examples of existing broadband access lines include systems such as ADSL and cable modems. PON is expected to provide wider bandwidth worldwide. [0003] Meanwhile, Worldwide Interoperability for Microwave Access (hereinafter referred to as "WiMAX") as a broadband wireless communication system in areas where installation of metal lines or optical fibers is difficult is attracting attention. Recently, Fixed Mobile Convergence (FMC) has been proposed to simplify the...
