Abstract:
Dynamic advertisement routing is disclosed. For example, a plurality of internet protocol ("IP") addresses associated with respective plurality of target nodes is stored in a routing pool. Each IP address in the routing pool is pinged through each of first and second load balancer network interfaces. Network routes associated with target nodes are updated based on a first plurality of ping responses. Communications sessions are established with target nodes through respective network routes. IP addresses are pinged and respective latencies in a latency cache are updated based on a second plurality of ping responses. A first request directed to the plurality of target nodes is received and is determined to be sent to a first target node based on the latency cache forwarded to the first target node via the first network route.
Abstract:
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.
Abstract:
The present disclosure describes a method, an apparatus, and a computer readable medium for congestion control in wireless communications. For example, the example method may include determining a plurality of picture transmission deltas, wherein a picture transmission delta is a difference between transmission times of two consecutive pictures. The example method further includes determining whether congestion associated with receiving real-time transport protocol (RTP) packets is present based on a picture transmission delta jitter, determining a new maximum bit rate based on a current maximum bit rate and a determination that congestion is present, and transmitting the new maximum bit rate to a sending device.
Abstract:
A network system for increasing data throughput and decreasing transmission delay along a data link from a source node to a sink node via a relay node, comprising: a first node configured to encode a second plurality of data packets based on an estimated rank distribution expressing a quality of the data link and transmit the second plurality of data packets; and at least one second node configured to: receive at least one of a first plurality of data packets transmitted from the first node prior to receiving at least one of the second plurality of data packets, estimate a rank distribution based on one or more of the first plurality of data packets, transmit the estimated rank distribution to the first node, and if the at least one second node has received a sufficient quantity of the first plurality of data packets, regenerate the first plurality of data packets.
Abstract:
Examples disclosed herein relate to the scheduling, generation, and transmission of propagation measurements between mobile computing devices to aid the location detection of the devices. A bulk propagation fine timing measurement (BFTM) allocation message is generated by a scheduling mobile computing device that identifies other mobile computing devices in the area. The BFTM allocation message generated by the scheduling mobile computing device indicates a scheduling order for the identified mobile computing devices, and contention-free periods for the mobile computing devices to transmit the timing measurement messages. The responding mobile computing devices generate bulk propagation timing measurement (BPTM) messages that include propagation times between pairs of mobile computing devices-either two other devices or the responding device and another device. These BPTM messages are then transmitted during scheduled times frames indicated in the scheduling order.
Abstract:
A system, which uses the internet to deliver time sensitive information, includes an overlay node, having a plurality of overlay nodes, which are used to deliver the time sensitive information. To better characterize the connection between a sending node and a receiving node, the sending node periodically requests each overlay node in the path between the sending node and the receiving node to force a retransmission of a packet, while also forwarding that same packet to the next overlay node. In this way, the delay associated with each link in the path can be quantified and recorded by the receiving node. Based on the observed transmission delays, the receiving node may determine an optimal buffer time. This buffer time is the amount of buffering performed at the receiving node prior to outputting the time sensitive information.
