Techniques for determining network reliability using message success rates include a first node in a mesh network computing a transmitted message success rate associated with a connection from the first node to a second node, wherein the second node is a neighbor node to the first node; computing, based on a first accumulated transmitted message success rate and the transmitted message success rate, a second accumulated transmitted message success rate for a route from the first node to a target destination using the second node, wherein the first accumulated transmitted message success rate is received from the second node and is associated with intermediary connections between the second node and the target destination; selecting, based on the second accumulated transmitted message success rate, the second node from a plurality of neighbor nodes; and transmitting a message to the target destination via the second node.

ROUND-TRIP PACKET LOSS MEASUREMENT IN A PACKET-SWITCHED COMMUNICATION NETWORK
20230009799 · 2023-01-12 · ·

In a method for exchanging packets between first and second nodes of a packet-switched network, each packet comprises two fields settable to an idle value or measurement value. The first node transmits to the second node first packets having a filed set to measurement value. Upon reception of each first packet, the second node transmits back to the first node a second packet having a field set to measurement value. Upon reception of each second packet, the first node transmits to the second node a third packet having another field set to measurement value. A packet loss measurement is calculated as a difference between the number of first packets and the number of third packets.

Systems and methods for optimal channel selection

Embodiments described herein provide an optimal communication channel recommendation engine by assessing whether the environment the customer is situated in is conducive to the channel selected by the customer. Specifically, the optimal channel recommendation engine obtains data artifacts indicative of ambient noise, motion, customer sentiment, network quality, customer focus, and/or the like to assess quality of the environment and recommend an optimal channel for the communication between the customer and the call agent. With the recommendation to switch to a different channel, the client component resumes communication with the new channel and retains the context of the interaction.

Another method is disclosed wherein an actuator generates and transmits a plurality of simultaneous test packets, one per NID device, resulting into a plurality of test results, one per reflector, with quasi-synchronous performance metrics to sectionalize a network and more efficiently isolate fault or performance problems without the need for additional test packets to isolate the issue.

ENHANCED PATH SELECTION USING ONLINE DETECTION OF PATHS OVERLAPS

The method of some embodiments selects a backup overlay network route when rerouting data packets to avoid delays on a primary overlay network route. The method, for each of multiple overlay network routes, measures delays of data packet transmissions on the overlay network route. The method correlates changes in the delays of data packet transmissions sent through different overlay network routes of the plurality of overlay network routes. The method selects the backup overlay network route based on the backup overlay network route having a low correlation or no correlation of changes of delays with the primary overlay route. In some embodiments, multiple physical network routes underlie the multiple overlay network routes, and correlating changes in the delays of data packet transmissions sent through different overlay network routes of the plurality of overlay network routes includes identifying overlay network routes for which the underlying physical network routes share infrastructure.

Unique ID generation for sensors

Systems, methods, and computer-readable media are provided for generating a unique ID for a sensor in a network. Once the sensor is installed on a component of the network, the sensor can send attributes of the sensor to a control server of the network. The attributes of the sensor can include at least one unique identifier of the sensor or the host component of the sensor. The control server can determine a hash value using a one-way hash function and a secret key, send the hash value to the sensor, and designate the hash value as a sensor ID of the sensor. In response to receiving the sensor ID, the sensor can incorporate the sensor ID in subsequent communication messages. Other components of the network can verify the validity of the sensor using a hash of the at least one unique identifier of the sensor and the secret key.

Device for and Method of Radio Access Technology Selection Among Multiple Radio Access Technologies

Systems and methods of providing a V2X communications are generally described. A geographically-limited, operator-independent mapping table is used that maps between groups of V2X applications each associated with a different application category and a different RAT preferred for the V2X application category. Each grouping is based on fulfillment of one or more KPIs for the associated V2X application category. Multiple RATs are prioritized if able to fulfill the KPIs. The mapping table is modified based on the RATs supported by the V2X UE. Carrier aggregation is used when simultaneous transmission on different RATs is desired.
