Disclosed herein is technology to reduce latency of frames through a network device supporting various priorities. In an implementation, a method comprises configuring one or more priorities with a preemptive right over other one or more of said plurality of priorities; receiving frames in a sequence, each of the frames having a frame priority comprising of one of said plurality of priorities; queuing the received frames in a predetermined order based on a frame arrival time and the frame priority; transmitting a current frame based on a current frame priority and current frame arrival time; stopping transmission of the current frame when a later frame in the sequence is received that has a later frame priority with preemptive right over the current frame priority; transmitting an invalid frame check sequence; transmitting the later frame; and restarting the transmission of the current frame after transmitting the later frame.

Systems, methods, and computer-readable media for updating configurations in sensors deployed in multi-layer virtualized environments. In some examples, a system can track information of sensors and collectors in the network. In response to determining that a specific collector becomes unavailable (e.g., the specific collector is down, offline or becomes unsupported), the system can determine affected sensors corresponding to the specific collector, determine a new collector among active collectors of the network for each of the affected sensors, and dynamically update configuration and settings of the affected sensors to maintain proper collector-to-sensor mappings and other settings on the affected sensors.

A method for establishing a stream in a Time-Sensitive Networking (TSN) network, wherein a request message is sent by a stream subscriber to a Domain Name System (DNS) server, upon which entries are stored that each comprise a stream identifier of a first type assigned to a stream, and a stream identifier of a second type that is different from the first type and is assigned to the respective stream, and the specification of a predefined type exclusively used for, or forms these types of entries, where the request message comprises a stream identifier of the first type and the predefined type known to the at least one stream subscriber, where the stream subscriber receives a response message from the DNS server, which contains a stream identifier of the second type belonging to the stream, and where the stream subscriber logs on to the stream using the stream identifier obtained.

Systems, methods, and computer-readable media are provided for determining a packet's round trip time (RTT) in a network. A system can receive information of a packet sent by a component of the network and further determine an expected acknowledgement (ACK) sequence number associated with the packet based upon received information of the packet. The system can receive information of a subsequent packet received by the component and determine an ACK sequence number and a receiving time of the subsequent packet. In response to determining that the ACK sequence number of the subsequent TCP packet matches the expected ACK sequence number, the system can determine a round trip time (RTT) of the packet based upon the received information of the packet and the received information of the subsequent packet.

Described embodiments provide systems and methods for inferring a network type and network conditions. The system includes a packet capturing engine configured to capture a plurality of network packets from a plurality of TCP network connections. The system includes a packet analyzer configured to analyze the plurality of network packets to generate a plurality of metrics. The system includes a network classifier configured to infer network types of the plurality of TCP connections based on the plurality of metrics and at least one classification model. The system also includes a conditions ranking engine configured to estimate a level of network congestion for each TCP connection based on the plurality of metrics and the network types.

In examples of the present invention, during delivery of content, the round trip times for each delivered data packet are measured and the congestion window used for delivery is adjusted accordingly. The congestion window is set to a relatively high value when the round trip times are relatively low, and set to a relatively low value when the round trip times are relatively high.

The present invention relates to a method for transmitting a control message by a control entity in a software defined network-based mobile communication system, the method comprising the steps of: detecting the occurrence of at least one event associated with at least one terminal; buffering the at least one event until a predetermined condition is satisfied; and transmitting, to a switching entity, a control message corresponding to the at least one buffered event when the predetermined condition is satisfied. However, the present invention is not limited to the above embodiment, and other embodiments are possible.

Latency reduction by fast forward (FF) in multi-hop communication device and/or systems is disclosed. Packets may be received and forwarded using a codeword (CW)-based approach with and/or without per-CW CRC. A FF session may have a flow ID and packets may have sequence numbers. Packets targeted for FF may be divided into independently decodable CWs that may be transmitted in the next hop, for example, as soon as the destination is determined without waiting for an entire packet's arrival and/or for CRC verification. Low latency (e.g. FF) traffic may be indicated. CW-based FF may be extensible for an e2e RAN path from a WTRU to the last access node in a RAN. Intermediate metrics, a packet CRC and/or a per-CW CRC may be utilized for data integrity. HARQ and/or CW retransmission procedures may be implemented between network nodes for error handling.

The disclosure relates to devices and methods for implementing an application-based quality of service notification scheme, in particular for URLLC services in a 5G communication network. According to a first aspect the disclosure relates to a method for providing a communication service in a communication network, wherein the method comprises: a network application entity providing communication service quality information, in particular a communication service quality measure value, to a network management and/or control entity of the communication network, wherein the communication service quality information is determined based on timing information.

The proposed technology generally relates to a method for controlling multi-point data transmission between a primary node (100) and a User Equipment, UE, via secondary nodes (101, 102). The method comprises the steps of obtaining (S1) Round-Trip Time, RTT, values (T.sub.RTT,backhaul,i) between a primary node (100) and two or more secondary nodes (101, 102). The method further comprises determining (S2) a time value relationship (α.sub.i) between uplink and downlink for each of the obtained RTT values; determining (S3) a first queue dwell time (T.sub.ref,queue,1) in a first secondary node (101) of the two or more secondary nodes (101, 102); and determining (S4) a second queue dwell time (T.sub.ref,queue,2) in a second secondary node (102) of the two or more secondary nodes (101, 102), the second queue dwell time (T.sub.ref,queue,2) being determined at least partly based on the RTT values (T.sub.RTT,backhaul,i), the time value relationship (α.sub.i) and the determined first queue dwell time (T.sub.ref,queue,1). The method further comprises initiating control (S5) of the first and second queue dwell times for synchronized data arrival in the UE.
