Transmitting from a wireless router a live stream of time stamped multimedia packets from a server which is capable of providing a system time clock value is disclosed. The wireless router includes a queue for storing the time stamped multimedia packets received from the live streaming server. The wireless router also includes a processor for analyzing the priority of the time stamped multimedia packets stored in the queue, for comparing the time stamps to the system time clock value, for calculating a transmission time to a video client, and for determining a transmission window to transmit the time stamped multimedia packets. The time stamped multimedia packets are discarded if the packets cannot be transmitted within the transmission window, or the time stamped packets are immediately transmitted if they can be transmitted within the transmission window. The priority of the packets in queue may be re-sorted prior to transmission.

Techniques for using traceroute with tunnels and cloud-based systems for determining measures of network performance are presented. Systems and methods include receiving a request, from a client, for a trace of the tunnel; causing the trace inside the tunnel; obtaining results of the trace inside the tunnel; and sending the results of the trace inside the tunnel to the client so that the client aggregates these details with details from one or more additional legs to provide an overall view of a service path between the client and a destination.

This application provides example data packet transmission methods and example communications apparatuses. One example method includes receiving a data packet, where the data packet is in an undelivered state. The data packet can then be delivered during running of a reordering timer upon an arrival of a first delay cut-off moment corresponding to the data packet or an arrival of a second delay cut-off moment of an additional data packet before the data packet in a reordering window.

A method for continuously providing an edge computing service to user equipment (UE) by an edge enabler server (EES) of a mobile edge computing (MEC) system is provided, which includes receiving, from a source edge application server (EAS), update information including UE information and source EAS information, wherein the source EAS provides the edge computing service to the UE; retrieving, from an edge configuration server (ECS), target EES information based on the update information; transmitting, to a target EES, the UE information and the EAS information based on the target EES information; receiving, from the target EES, target EAS information; and transferring, to the source EAS, the target EAS information.

A method of a user equipment (UE) in a communication system for obtaining and transmitting synchronization information is provided. The method includes obtaining synchronization information from a first communication network, and transmitting the synchronization information to a second communication network. The synchronization information is updated based on an obtainment time from the first communication network and a transmission time to the second communication network. The UE operates as a device-side time sensitive networking (TSN) translator (DS-TT).

A mobile communication device for receiving an ad hoc temporary upgrade in quality of service (QoS). The mobile communication device comprises a processor, at least one cellular radio transceiver, a non-transitory memory, and an ad hoc service upgrade application. When executed by the processor, the application monitors wireless cellular communication on a network via the at least one cellular radio transceiver, detects a significant delay in the communication, generates a prompt on a GUI, the prompt comprising a plurality of options for an ad hoc temporary upgraded QoS, where each option is associated with a time period. The application further, based on a user input, requests a preferred roaming list (PRL) associated with the temporary upgraded QoS, receives the PRL, wherein the PRL is associated with providing the upgraded QoS on an allocated spectrum, activates the received PRL, and upon expiration of the time period, deactivates the received PRL.

In an example, a node in a network includes four ports coupled to respective nodes via respective links. A first port and a third port are coupled to respective nodes via respective near links and a second port and a fourth port are coupled to respective nodes via respective skip links. The node further includes at least one processor configured to send a first message in a first direction via the second port, and the first message includes a first destination address that corresponds to the second side of the node. The at least one processor is further configured to send a second message in a second direction via the fourth port, and the second message includes a second destination address that corresponds to the first side of the node.

In an example, a method includes forming a first self-checking pair including a self-checking node and a first node adjacent to the self-checking node in a network. The method further includes forming a second self-checking pair including the self-checking node and a second node adjacent to the self-checking node in the network, wherein the self-checking node is between the first node and the second node. The method further includes transmitting a first paired broadcast with the first self-checking pair and transmitting a second paired broadcast with the second self-checking pair.

Systems, apparatuses, and methods for reducing network bandwidth usage by a fleet of robots. According to at least one non-limiting exemplary embodiment, robots coupled to a server collect and produce a substantial amount of data, only a portion of that data being useful for operators to monitor behavior of the robot. The present disclosure provides for, inter alia, optimized systems, apparatuses, and methods for operators to extract the useful data using only reduced bandwidth of cellular LTE networks or Wi-Fi networks.

A computing device includes a volatile memory that includes a first cache, a non-volatile storage that includes a second cache, and a cache service. The cache service, responsive to a cache miss, retrieves that asset and writes that asset to the first cache and not the second cache. The cache service reads the asset from the first cache responsive to requests for the asset until the asset is evicted from the first cache or until the asset is promoted to the second cache. The cache service promotes the asset to the second cache upon determining that a set of one or more criteria are satisfied including a predefined number of cache hits for the asset when it is in the first cache. The cache service reads the asset from the second cache responsive to requests for the asset until the asset is evicted from the second cache.
