摘要： A method (200) is proposed for determining a round-trip delay time (RTT) between first (PA) and second (PB) points of a communication network (105) based on data units propagating according to a first protocol belonging to a first protocol layer, and to a second protocol belonging to a second protocol layer higher than the first protocol layer, wherein said data units comprise first (DUA) and second (DUB) data units that, during propagation, are at the first and second points, respectively. The method comprises: - associating (205A, 210A) with each first data unit (DUA) a respective first timestamp with respect to a first reference time (RTA); - associating (205B, 210B) with each second data unit (DUB) a respective second timestamp with respect to a second reference time (RTB) different from the first reference time; - recognizing (215), among said first and second data units, first messages (FMj) each one comprising a respective pair of first and second data units that propagate in a first direction (XAB) between the first and second points and that match to each other based on the first protocol, - recognizing (215), among said first and second data units, second messages (RMk) each one comprising a respective pair of first and second data units that propagate in a second direction (XBA) opposite the first direction and that match to each other based on the first protocol, - identifying (220), among said first and second messages, a round-trip message (RTM) comprising a pair of first and second messages wherein the second message has been originated, according to the second protocol, in response to the first message; - determining (225) the round-trip delay time based on the first and second timestamps associated with the first and second data units of the round-trip message.

摘要： Techniques are described for utilizing entropy labels of a Multiprotocol Label Switching (MPLS) label stack for performing monitoring operations (e.g., telemetry, performance measurement, OAM, etc.) without altering the MPLS label stack and/or packet path (e.g., ECMP path). The techniques may include determining, by a node of a network, to perform a monitoring operation associated with traffic that is to be sent along a path through the network. In some examples, the node may receive a packet that is to be sent along the path and encapsulate the packet with an MPLS header. The MPLS header may include an entropy label, entropy label indicator, or other label that is capable of carrying a flag indicating the monitoring operation to be performed. The flag may be carried in a TTL field or traffic class field of the label such that the MPLS label stack is not altered to trigger the monitoring operation.

摘要： Systems and methods are described implementing streaming analytics on a serverless compute system. A user can specify a data stream against which analytics should be conducted, serverless functions to be used to conduct the analysis, and criteria for the analytics, such as windowing criteria and aggregation criteria. The windowing criteria can specify windows of items within the stream that should be collectively analyzed. The aggregation criteria can specify how to group items within each window during analysis. A poller device can read data items from the stream, window and group the items according to the windowing and aggregation criteria, and invoke serverless functions to conduct streaming analytics on the data items. The poller device can further maintain state between invocations.

摘要： We generally describe a method (700) for analyzing data traffic quality of data traffic flowing between a user equipment and a server of a video service provider. The data traffic comprises video traffic and audio traffic. The method comprises separating (S702), in the data traffic, the video traffic from the audio traffic, and analyzing (S704), based on the separated video traffic, the data traffic quality of the data traffic flowing between the user equipment and the server of the video service provider.

摘要： A network communication system may include intelligent electronic devices (IEDs) in a ring communication network. A software-defined networking device may be programmed by a removable or disconnectable software-defined network (SDN) controller to control the flow path of data packets to the IEDs in the ring network. The software-defined networking device may inspect a data packet intended for a first IED to determine that the inspected data packet requests a responsive data packet from the first IED. A flow path failure may be identified based on a failure to detect a responsive data packet from the first IED within an expected response time.
