Techniques that provide low latency traffic segregation to ensure an edge user plane (UP) is not overloaded are described herein in at least one embodiment. In at least one embodiment, a method may include determining offload of low latency traffic of a user equipment (UE) at a mobile network edge, wherein the UE has non-low latency traffic associated with a first packet data network session for an access point name; notifying the UE to request creation of a second packet data network session for the access point name; selecting an edge UP element to handle the low latency traffic for the second packet data network session; creating the second packet data network session at the selected edge UP element; and notifying the UE that second packet data network session is created.

An ingress packet processor in a device corresponds to a group of ports and receives network packets from ports in its port group. A traffic manager in the device manages buffers storing packet data for transmission to egress packet processors. An ingress arbiter is associated with a port group and connects the port group to an ingress packet processor coupled to the ingress arbiter. The ingress arbiter determines a traffic rate at which the associated ingress packet processor transmits packets to the traffic manager. The ingress arbiter controls an associated traffic shaper to generate a number of tokens that are assigned to the port group. Upon receiving packet data from a port in the group, the ingress arbiter determines, using information from the traffic shaper, whether a token is available. Conditioned on determining that a token is available, the ingress arbiter forwards the packet data to the ingress packet processor.

A method for delayed cyclic forwarding of messages by a system includes: receiving, by an input side of the system, the messages to be forwarded; and sending, by an output side of the system, the messages to be forwarded to a receiving device. A check is performed to determine whether the difference between a current system time and a receive time of a message under consideration is greater than or equal to the delay time. In the event that the difference is greater than or equal to the delay time, the message that has been in the buffer memory for the next longest time being checked in the same manner, and the checking of the messages is continued until a difference smaller than the specified delay time is found for a message.

A system and method is disclosed of extracting information from real-time network packet data to analyze connectivity data for client devices in a network. The method includes: detecting when client devices initiate a connectivity event; after detecting a connectivity event, waiting a period of time for the client device to either reach or fail to reach a network connected state; after waiting a period of time, recording connectivity event information; and sending the recorded connectivity event information to an analytics system for network incident and/or network congestion analysis.

A controller obtains a forwarding latency requirement of a service flow and a destination address of the service flow, and determines a forwarding path that meets the forwarding latency requirement. The controller determines that an ingress node forwards a first cycle time number of a packet and an intermediate node forwards a second cycle time number of the packet, and separately determines a corresponding adjacent segment identifier. A label stack generated by the controller includes the adjacent segment identifier and the adjacent segment identifier. The controller sends the label stack to the ingress node, to trigger the ingress node to forward the packet within a period of time corresponding to the first cycle time number. The controller determines the forwarding path based on the forwarding latency requirement of the service flow, and generates a label stack corresponding to a forwarding time point.

Embodiments include methods for managing a reordering timer performed by a processor of a wireless device. The processor may receive packets from a communication network and store the packets in a memory buffer of the wireless device. The processor may detect one or more conditions that affect an amount of time required to reorder or reassemble at least some of the packets received from the communication network. The processor may determine a timer adjustment based on the detected one or more conditions. The processor may adjust a timer with the determined timer adjustment. The processor may deliver one or more packets from the memory buffer in response to expiration of the adjusted timer.

Example video data transmission methods and apparatus are described. One example method includes receiving a plurality of data packets corresponding to a plurality of video frames by a network device from a server. The network device determines that a transmission phase of one or more data packets corresponding to each video frame in the plurality of video frames, and determines a corresponding priority based on the transmission phase of the one or more data packets corresponding to each video frame. The network device sends, based on the priority of the one or more data packets corresponding to each video frame, the one or more data packets corresponding to each video frame to a terminal device corresponding to each video frame.
