摘要: In particular embodiments, a network element filters information sent to a neighboring network element. In the embodiments, the core network element may determine whether the neighboring network element is an edge network element or a core network element. If the neighboring network element is an edge network element, the core network element may set a filter, remove traffic engineering information according to the filter, and send the remaining information to the neighboring network element.

摘要: An example embodiment includes a network element. The network element includes an ingress port, an ingress line card, a link aggregation group (LAG) including multiple egress ports, and a distributor. The ingress port receives multiple packets including flood traffic. The ingress line card separates the packets into buckets. The distributor is configured to allocate the buckets to the egress ports, transmit the buckets to the egress ports, and when a failed egress port is identified, reallocate the buckets from the failed egress port to at least one functional egress port while continuing to transmit the buckets to functional egress ports of the LAG.

摘要: Systems and methods for identifying a fault location in an optical network are disclosed. In accordance with one embodiment of the present disclosure, a method for identifying a fault location in an optical network comprises monitoring, by a network element, an eastward optical path and a westward optical path for faults. The method further comprises transmitting, by the network element, a first data packet along the eastward path and a second data packet along the westward path. The first and second data packets comprise an eastward fault indicator and a westward fault indicator comprising information associated with any eastward or westward faults occurring on the eastward or westward paths. The fault indicators indicate the existence of an eastward or westward fault and the network element that detected the fault.

摘要: A sun visor glare reducing extension for incorporation within a vehicle's sun visor is disclosed having a three sided rigid frame capable of being incorporated within a vehicle's sun visor. The frame has a back frame member pivotally affixed to a pair of generally parallel leg segments at each end. Each leg segment forms a "U" shaped retaining channel. A glare shield slidably retained within the "U" shaped retaining channels, and is deployable in a linear manner from the edge of an otherwise conventional sun visor.
