|20150146526||NETWORK CONGESTION MANAGEMENT USING FLOW REBALANCING - Systems and methods are disclosed for managing congestion in a data network. In a data network, various data flows are transmitted between source and destination nodes. One or more computing devices of the network may be configured to detecting congestion in a first path and provide an indication of the congestion, directly or indirectly, to a destination device. A switch associated with the path is designated for performing rebalancing of the flow based at least in part on a control message generated in response to an instruction received, either directly or indirectly, from a source device. Reassignment of the congested flow to a new path can help alleviate congestion and improve network performance.||05-28-2015|
|20080304822||Response to OTUk-BDI for OTN Interfaces to Restore Bidirectional Communications - In an OTN (Optical Transport Network), an OTN interface of a network element may receive a BDI (Backwards Defect Indicator) signal from a far end network element to which OTN frames are being transmitted. A BDI signal indicates the occurrence of a unidirectional failure in the transmission of OTN frames to which the far end network element responds by switching its routing to the network element. The OTN interface generates an AIS (Alarm Indication Signal) for its network element so that the network element switches network communication channels to the far end network element to ensure bidirectional switching upon a unidirectional failure.||12-11-2008|
