    摘要： Systems and methods for service preemption selection in a network include receiving, from an ingress link, a request to establish a service on a path in the network while preempting one or more existing services if required to establish the service, wherein the request comprises a list of any previously selected services for preemption and an indication of whether preemption is required on the ingress link, wherein the service and the one or more existing services comprise an end-to-end path in the network; selecting, if required based on the indication, one or more services for preemption on the ingress link based on service selection criteria; and forwarding the request on an egress link to an adjacent node with any updates based on the selecting.

    摘要： Systems and methods provide a guided cable assist that blinks port LEDs on the faceplate cage of modules as an indication that assists the user in cabling a system optimally from start to finish. The systems and methods include receiving a signal responsive to a first end of a cable being coupled to a first port in a system; providing an indication, wherein the indication signifies where a second end of the cable is to be coupled; and responsive to the second end of the cable being coupled, performing a validation check of the cable connection.

    摘要： The disclosure generally relates to mechanisms to protect hybrid networking equipment at a port level granularity and thereby provide capabilities to specify the protection of client services on a port-by-port basis. For example, in one embodiment, a Virtual Connection Point (VCP) may be established as a termination point for a transport-side network connection and configured as a Layer 1 bridge/select connection to switch among any one of a plurality of backplane Layer 1 termination points. The plurality of backplane Layer 1 termination points may be protected using a link aggregation group, wherein a Layer 2 switch may be established to direct packets between the link aggregation group and the VCP configured as the Layer 1 bridge/select connection.

    摘要： Methods and systems can suppress invalid defect detection when Out-Of-Frame (OOF) conditions occur within an Optical Transport Network. One method for processing a report of a defect during an OOF condition may include detecting the OOF condition at a downstream node, detecting an indication of the defect caused by the OOF condition, suppressing a report associated with the indication of the defect, determining whether the OOF condition is clear, determining whether the indication of the defect is still present if the OOF condition is clear; and cancelling the report if the indication of the defect is not present. A network node which processes a report of a defect during an OOF condition may include a network interface, and a processor which is coupled to the network interface. The processor may be configured to perform a method for suppressing invalid defect detection during OOF conditions.
