    摘要： A method for assigning a severity to failure indications of network resources in a multilayered communication network includes in a processor, receiving one or a plurality of failure indications related to a failure of one or more network resources from a plurality of network resources in a communication network. A severity may be assigned to the one or said plurality of failure indications based on an impact on data, wherein assigning the severity includes at least one of: assigning a static severity based on a single traffic impact assessment in the communication network due to the one or more failed network resources, and assigning a dynamic severity based on continuous or periodic traffic impact assessments in the communication network due to the one or more failed network resources. The severity of the one or said plurality of failure indications may be outputted on an output device.

    摘要： A method for analyzing failures in network resources in a multilayered communication network using passive shared risk resource groups may include, in a processor, identifying network resources in a plurality of network resources having common risk attributes. The network resources may be grouped into one or more passive shared risk resource groups (PSRG) based on the common risk attributes. A likelihood of a PSRG failure may be assessed for each of the one or more PSRGs.

    摘要： A computerized system for performing preparation operations for a maintenance activity that causes a disruption in a communication path of traffic over a multilayer network. The system comprising: a maintenance tool configured to coordinate maintenance activities of the multi-layer network based on maintenance activity-data, a storage unit to store the maintenance activity data; and a multi-layer control system comprising a processor, wherein said processor is configured to: receive from the maintenance tool an indication that one or more maintenance activities are required on an indicated optical resource, determine an affected optical path, determine an affected IP link utilizing said affected optical path; remove traffic from the affected IP link; remove the affected optical path; activate an alternative optical path; configure the packet switching layer to utilize the alternative optical path; and repeat for each alVecied optical path and each affected IP link.

    摘要： Migrating data traffic from legacy networks to packet networks by inserting a first circuit emulation device (CEM) at a first endpoint and a second circuit emulation device (CEM) at a second endpoint of a connection in the legacy network, duplicating data traffic provided to the first CEM by routing one copy of the data traffic over the connection in the legacy network to the second CEM and one copy of the data traffic over a packet network from the first CEM to a comparison server, duplicating data traffic provided to the second CEM over the legacy network from the first CEM by routing one copy of the data traffic to customer communication equipment and one copy of the data traffic to the comparison server, comparing the data traffic routed to the comparison server and validating that the packet network can be used to replace the connection in the legacy network.
