摘要： A method for performing root cause analysis of failures in a computer network is provided. The method includes receiving an Adaptive Service Intelligence (ASI) data set related to one or more failures reported in the computer network from a plurality of interfaces. One or more impact events associated with the reported failures are identified based on the received ASI data set. Each of the identified impact events is correlated with one or more cause events. A situation record is selectively generated based on the correlation results.

摘要： The present invention provides a path detection method and apparatus. The method includes: when there are multiple equivalent paths between a source virtual extensible local area network VXLAN tunnel endpoint VTEP and a destination VTEP, generating M VXLAN probe packets according to a source User Datagram Protocol UDP port number, a destination UDP port number, and a probe identifier; sending the M VXLAN probe packets to the source VTEP, so that the source VTEP forwards the M VXLAN probe packets to the destination VTEP; receiving VXLAN advertisement packets reported by the source VTEP, the destination VTEP, and intermediate nodes in the multiple equivalent paths according to the M VXLAN probe packets; and detecting, according to the VXLAN advertisement packet, whether a fault occurs in a path of the multiple equivalent paths between the source VTEP and the destination VTEP. According to the present invention, a faulty path can be found in a timely manner, and corresponding processing can be performed to avoid impact caused by long-time existence of the faulty path.

摘要： A communications apparatus (102) transmits a registration request for a reference hop count. Each node (101), when receiving the registration request, obtains and registers as a reference hop count, the hop count of the registration request. Each node (101), when transmitting to the communications apparatus (102), data measured by a sensor, adds the reference hop count to the sensor data. The communications apparatus (102) receives the sensor data transmitted from each node (101), compares the actual hop count of the received sensor data and the reference hop count added to the received sensor data, and determines whether failure has occurred at a given node (101) included in a node group (101s).

摘要： The cause of an abnormality is identified easily to allow quicker recovery from it. An information processing apparatus is connected to a control system including a first network allowing constant period communication connected to a first node for managing the constant period communication and to one or more second nodes other than the first node. The apparatus includes a first obtaining unit that obtains, from the first node, first status information indicating a communicating status of each second node in the first network, a second obtaining unit that obtains second status information indicating an operating status of each second node, a third obtaining unit that obtains third status information indicating an operating status of a second node that includes a predetermined type device, and an output unit that outputs, for each second node, the first status information, the corresponding second status information, and the corresponding third status information in line.

摘要： A system and method for providing Connectivity Fault Management, CFM, in a Provider Backbone Bridge Traffic Engineering, PBB-TE, telecommunication network utilizing Ethernet-based packet transport. PBB-TE point-to-point and point-to-multipoint services are identified, and PBB-TE maintenance points (31, 41) associated with the identified PBB-TE services are addressed. The addressed PBB-TE maintenance points are modified by adding a PBB-TE Service Demultiplexer (32, 42) to each PBB-TE maintenance point for identifying independent PBB-TE service instances. Basic CFM protocols are enhanced to duplicate the behavior of CFM protocols on virtual local area network, VLAN, based maintenance associations. The PBB-TE maintenance points may be Maintenance association End Points, MEPs, and Maintenance association Intermediate Points, MIPs.

摘要： Embodiments of the present invention disclose a method and an apparatus for detecting connectivity. An SDN device transmits a session negotiation packet to a second network element, where the session negotiation packet is used to negotiate a link between a first network element and the second network element, and the first network element is located in an SDN network; the SDN device obtains a response message returned by the second network element, to determine that the link is negotiated successfully; and the SDN device transmits a heartbeat packet to the second network element, where the heartbeat packet is used to detect connectivity of the link. As can be learned, after determining that the link between the second network element and the first network element located in the SDN network is negotiated successfully, the SDN device transmits the heartbeat packet to the second network element, so as to effectively detect the connectivity of the link. In this case, in an SDN network architecture or a hybrid network architecture having an SDN network architecture, link connectivity between the first network element and the second network element in the SDN can also be effectively detected.
