摘要： A method and apparatus that includes processing for providing reliable interoperation of the plurality of independent software modules. Such processing begins by determining selection of an object by one of a plurality of independent software modules to produce a new object selection. The processing then continues by determining object selection status, which indicates a selected object and an associated one of the plurality of independent software modules. In other words, the object selection status indicates which independent software module is currently managing a particular object. The processing then continues by updating the object selection status when a difference occurs between at least one of the independent software modules identified currently in the object selection status and the independent software module selecting the object, and/or the newly selected object is different from the object identified in the object selection status. In other words, the object selection status is updated to correspond the selecting software module to be responsible for management of the selected object. If such was already indicated in the object selection status no change occurs.

摘要： Methods and components are provided which ensure both the improved use of network resources and adequate performance of best effort (BE) traffic by intelligently distributing the BE traffic demands at connection level with corresponding scaling weights, and without reserving bandwidth. A weighted sum of the best effort (BE) class connections (or LSPs in MPLS context) in a link is used as a path selection criterion, where each BE connection is weighted by its service volume. Path selection for a requested BE service volume is performed by creating a virtual topology in which all links in a network have weighted BE metrics updated to include the effects of the requested BE service volume, and identifying a best path through the virtual topology taking into account the weighted BE metrics.

摘要： Methods and network nodes are provided which are adapted to perform protection switching on the basis of raw signal quality information, such as raw BER information, in a manner which instigates the protection switching before an actual failure has occurred. In some embodiments, these methods leverage forward error correction and uncorrected BER to effect traffic redirection before faults are observed at layer 2 and above. This is as opposed to the method of switching layer 2 traffic in response to bitstream characteristics observed at that layer.

摘要： A pluggable transceiver, and its use, looping back Layer 2 and higher data in an Ethernet network element. The transceiver has upstream and downstream datapaths, a logic array having first and second complimentary latching loopback logic blocks (LLBLBs) connected in series through both datapaths. The first LLBLB receiving an upstream datapath frame, comparing it to loopback conditions and looping back the frame on the downstream datapath if the conditions match. If the conditions did not match, the frame is sent to the other LLBLB. The first LLBLB receiving a frame from the second LLB and transmitting it on the upstream datapath with priority over any loop back frames to maintain the upstream throughput requirements of the pluggable transceiver. The second LLBLB operates in mirror image with respect to the datapaths.
