    摘要： The present disclosure provides protection systems and methods that provide a mechanism to identify/determine when an interconnection node has been isolated (i.e. when there is no connectivity between a pair of interconnection nodes), from a data path perspective. If/when this condition exists, actions are triggered on the subtending sub-ring that essentially perform a protection switch (which causes the subtending sub-ring nodes to cleanse their forwarding tables), and, more importantly, that remove any channel blocks on the subtending sub-ring. Extensions to the ITU-T G.8032 state machine are also provided that include support for operator command interactions (e.g. DNR, force switch, manual switch, etc.). The protection systems and methods of the present disclosure enable the reliable application of ITU-T G.8032 and the like to more complex (i.e. meshed) deployment environments, among other significant advantages.

    摘要： A method and system are provided for controlling the operating temperature of a torque converter during torque converter stall conditions. The torque converter has a pump rotatably driven by an internal combustion engine and a rotatable turbine fluidly coupled to the pump. The system first determines whether the torque converter is currently in a torque converter stall condition, and, if so, determines a slip speed as a difference in rotational speeds between the pump and the turbine, determines an engine output torque limit as a function of the slip speed and a desired slip speed, and controls the operating temperature of the torque converter by limiting output torque produced by the engine based on the engine output torque limit.

    摘要： A method for processing automatic protection switch (APS) messages at a network element in a tunnel provisioned across a data transport network in order to provide for distributed processing of protection switch request messages involves receiving new APS message at the NE; determining whether the NE is an end point of the tunnel, or a tandem of the tunnel and processing the message accordingly. If the NE is a tandem, message processing involves using local information about tunnel segments of the tunnel only maintained by the NE, to update the local information, and to selectively forward the updated information to adjacent NEs of the tunnel. If the NE is an end point, it updates a status of the tunnel. In a preferred embodiment all NEs are responsible for controlling pending and preemption indicators, and for initiating tunnel condition messages, and the end point NEs are responsible for initiating all other messages.

    摘要： A method for providing grades of service to unprotected traffic on an optical network that provides protection channels associated with working channels, defines a linearly ordered set of protection switch request priorities, and two or more grade of service priorities, and uses those priorities to enforce a protection access policy. The unprotected traffic may be of a high priority, approximating non-pre-emptable unprotected traffic (NUT); of low priority, like extra traffic; or may be of an intermediate priority between the two. This allows data transport providers to offer different unprotected transport services at different rates on protected links, in which the different unprotected transport services are associated with different probabilities of pre-emption.

    摘要： A method for permitting a network element to transmit to a second network element a message over a link, that identifies a tunnel segment occupying predefined proportion of the data transport on the link, and a status of the tunnel, so that each tunnel may be provided with independent protection switching messaging involves providing an identifying scheme for locally identifying the tunnels passing through the tunnel segment. In order to permit this information to be sent over existing (narrow) automatic protection switching (APS) channels, the identifying scheme only provides a local identifier of the tunnel. To permit extended messaging to include messages that do not fit in a single K-byte overhead, extension bits are used to identify continuation of a message across multiple frames.
