Problems solved by technology

Different broadband value-added services have different bandwidth requirements. For example, services such as Internet access and downloading have relatively low bandwidth requirements. Even if a short-term network interruption occurs, users will hardly notice it and can bear it; voice services are rela

Abstract

The invention relates to a method for realizing bandwidth resource dynamic allocation in a point-multipoint optical network and a system thereof. The invention provides three types of bandwidth resource dynamic allocation mechanisms, namely fixed bandwidth allocation, bandwidth ensuring allocation and best effort allocation, for service development of the point-multipoint optical network. Three strategies can be provided respectively for developing wideband value-added services with different priorities and different service levels, so as to ensure that different types of wideband value-added services can be simultaneously supported under the condition of limited bandwidth resource, thereby effectively expanding wideband value-added service.

Description

technical field [0001] The present invention relates to the field of point-to-multipoint optical network communication technology, in particular to the application of broadband value-added services in point-to-multipoint optical networks, and specifically to a method and system for realizing dynamic allocation of bandwidth resources in point-to-multipoint optical networks . Background technique [0002] Optical network is commonly referred to as optical fiber network, and its transmission medium is optical fiber. In an ordinary network, the data signal is carried by electricity, and 0 and 1 are distinguished by the voltage level, while in an optical network, the data is carried by a laser, and the laser transmitter emits lasers of different intensities to distinguish 0 and 1. and 1. Since ordinary twisted-pair wires use electrical signals, the transmission distance is limited. For example, the theoretical maximum transmission distance of Category 5 wires is about 100 meter...
