    摘要: Methods, apparatuses, media and signals for providing clear channel access on a network are disclosed. A first method involves receiving a communication signal from a remote network element. The communication signal includes a previous transport overhead (PTOH) portion indicative of transport overhead contents of the communication signal prior to arrival at the remote network element, and a previous path error (PPE) portion indicative of path errors present in the communication signal at the remote network element. The method then involves modifying a transport overhead portion of the communication signal in response to the PTOH and PPE portions. A second method involves inserting into a communication signal received at a network element, a previous transport overhead (PTOH) portion indicative of transport overhead contents of the communication signal prior to arrival at the network element, and a previous path error (PPE) portion indicative of path errors present in the communication signal at the network element. The second method then involves transmitting the communication signal to a remote device.

    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.

    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.
