摘要： A source service node (200), a target service node (202) and methods therein, for transferring a service session for a wireless device (204) from the source service node (200) to the target service node(202) when a service application is executed in the source service node (200) for the wireless device (204) by means of said service session. The amount of application data that needs to be transferred from the source service node (200) to the target service node (202) for a wireless device that is handed over from a first base station (206) to a second base station (208) can be reduced by truncating the application data by an amount corresponding to the data pending in a downlink buffer at the first base station (206). Thereby, the target service node (202) is able to recreate the complete application buffer from the truncated application data and data from the downlink buffer, the latter data being transferred from the first base station (206) to the second base station (208) anyway according to regular handover procedures.

摘要： A method is implemented by a computing device to determine a root cause of a performance issue in a software defined networking (SDN) network using flow statistics maintained by hosts in the network. The method includes receiving a request to perform a root cause analysis (RCA) for a first flow in the network that is experiencing a performance issue, obtaining flow path information for flows in the network, and obtaining flow statistics for the flows in the network, where the flow statistics are end-to-end flow statistics maintained by one or more hosts in the network. The method further includes executing an RCA algorithm for the first flow, where the RCA algorithm determines a root cause of a performance issue experienced by the first flow based on the flow path information and the flow statistics.

摘要： The present disclosure relates to a method performed in a radio communications network which is configured to enable multipath communication. The method comprises providing an explicit indication (36) that a path within a multipath connection is a backup path prior to establishment on or handover to a radio link of the backup path, transmission (37) of the explicit indication to the base station, where it is interpreted (38). This allows an early indication that the path is a backup path and allows the base station to handle and prioritise use of radio network resources (39) and/or connection characteristics for the radio link (40). The explicit indication may be in the radio level signalling or in handover signalling.

摘要： Methods, devices, systems, and non-transitory computer-readable storage media for improving the reception of data at a computing device by proactively utilizing new TCP connections in response to identifying that TCP connections have stalled. In an embodiment, a processor of the computing device may perform operations including monitoring a status of requests via a plurality of TCP connections, identifying a stalled TCP connection having a missing request based on the monitoring, wherein the stalled TCP connection is configured to utilize a first network interface and access a first data source, evaluating other TCP connections to determine whether the other TCP connections stall using the first network interface or when accessing the first data source; identifying a second network interface and a second data source based on the evaluating, and reissuing the missing request with a new TCP connection configured to use the second network interface and access the second data source.
