摘要： The working fibre and protection fibre between pairs of nodes are shared between adjacent rings in a network, such that working traffic on the working fibre between the pair of nodes can be protected by the ring architecture of either of adjacent rings. A network management system routes signals across the network and dictates which rings within the network provide protection for the signal route. The ring structure enables protection for signal traffic on a ring to be protected by the ring protocols, providing rapid protection switching. It is also possible to select the location of protection bandwidth for a signal path across the network. In this way, protection bandwidth is shares and can also be configured to optimise the use of the total available protection bandwidth.

摘要： The present invention consists of a method of deactivating protection fiber resources in an existing optical interconnected ring network or system. The invention uses 1:N protection principles to provide a single protection path on spans interconnecting nodes common to two or more optical rings. With the sharing of a protection fiber or channel on spans interconnecting common nodes, the present invention eliminates the need for multiple protection paths on these spans and provides substantial fiber capacity savings. According to the invention, the protection fibers and equipment deactivated can be removed or alternatively re-provisioned to provide a cost-effective and efficient allocation of the resources available in the network.

摘要： The present invention relates to a local node for use in a synchronous optical network ring. The local node includes a group of working transmission lines and a protection line, for connecting to a remote node. The local node further includes a control unit for monitoring the working transmission lines and, upon detection of a data transmission impairment over a particular working transmission line, invoking a protection switch event causing re-routing of optical signals from the particular working transmission line to the protection line. Should the control unit detect simultaneous data transmission impairments over two or more working transmission lines, the control unit will choose to protect a particular working transmission line on the basis of a user-defined priority scheme.

摘要： The present invention provides a method of deactivating working fibers in an existing optical ring network or system for a cost-effective and efficient allocation of the fiber resources available in the ring network. When a working fiber is underutilized in an existing ring network, the traffic scheduled for transmission thereon is re-routed around the network away from the fiber and lockouts are applied to prevent the fiber to be removed from being protected. The fiber and associated connecting equipment thus become unused and unnecessary for traffic carrying purposes and can then be deactivated. By eliminating the need for working fibers and associated optics equipment on spans where traffic is low or non-existent, the invention can provide fiber capacity savings of up to fifty percent on each span while retaining full protection usage. According to the invention, the unused fibers and equipment can be removed or alternatively be re-provisioned for use in other network configurations to provide a cost-effective and efficient allocation of the resources available in the network.
