摘要： The invention relates to a control system and method in an optical burst mode network, said network comprising a plurality of channels, at least one channel adapted to carry bursts of data from multiple sources, the control system is configured to calculate a per channel gain measurement from the acquisition of per source received burst data measurements at a channel termination point. The invention facilitates automated per channel optical power monitoring and equalisation without human intervention over the operational life span of the optical system.

摘要： The invention provides an optical burst switch in an Optical Burst Switched (OBS) communication network, said optical burst switch comprising means for monitoring and maintaining mesh of virtual optical paths from a communication node to a plurality of other communication nodes, arranged in a ring network, enabling traffic data to be transmitted and/or received between nodes via a physical optical path. The switch also provides means for sending a data packet probe on a virtual path from a node to each other node in the OBS communication network, wherein data packet probe information received at said switch provides information of availability of the physical optical path for sending traffic data between nodes. The switch can be configured such that the rate at which this path monitoring is scheduled guaranteeing less than 50ms protection switch in the event of monitoring a failed or degraded path.

摘要： The invention provides a burst transmission optical fibre wavelength routed ring network and method comprising a plurality of nodes on a network ring where each node can drop and add a wavelength. The network has a control means to control the wavelength to be transmitted on the network ring in a burst transmit mode from each node over a scheduling interval. The invention provides a random generator for generating a plurality of gap intervals over the scheduling interval, such that the gap intervals allow for wavelengths from different nodes to transmit wavelengths in said gaps to achieve a fair access to bandwidth and fair latency in the ring network.
摘要翻译：本发明提供了一种突发传输光纤波长路由环网和包括网络环上的多个节点的方法，其中每个节点可以丢弃并添加波长。网络具有控制装置，用于以调度间隔从每个节点以突发传输模式控制在网络环上传输的波长。本发明提供了一种随机发生器，用于在调度间隔上产生多个间隙间隔，使得间隙间隔允许来自不同节点的波长在所述间隙中发射波长，以实现对环网络中的带宽和公平延迟的公平接入。
