Abstract: A communications network may include a bandwidth system and a statistics system in order to assess data packet loss in a communications network. The bandwidth system may operate to mark data packets as either high or low priority and to receive feedback information on data packet loss and jitter. The statistic system may operate to collect metrics relating to the performance of radio frequency equipment as well as the weather or environmental conditions of a local area network. Embodiments of these systems may allow for identification of data packet loss due to specific sources such as radio frequency intervention, congestion, and burstiness. Visualization outputs may also be provided to benefit the operator of the system.

Abstract: Systems, methods, and servers for controlling data flow across a computer network having a first performance enhancing proxy device (PEP1) between a client-facing segment of the network and a second PEP device (PEP2) on a server-facing segment of the network. PEP2 has a receiver for receiving flow control information from across a control channel between PEP1 and PEP2, for each TCP connection on the client-facing segment. The information includes round-trip packet latency (Li) on the client-facing segment and transmit buffer congestion information of PEP1. PEP2 has a determiner for determining if a TCP connection has a congested packet flow; and a congestion reliever for relieving such congestion by synchronizing a receive buffer of the PEP2 to be the same size as a transmit buffer congestion window of the PEP1; and delaying acknowledgments (ACKs) at PEP2 by a time Tack based on a preset threshold level Tlim or Li.

Abstract: System for setting up conversations between an institution, such as a bank, and an end client, where the conversations may be initiated both by the institution and by the client, using the transmission of SMS short messages. The system includes a set of components, including an institution HOST, a first server with an associated first database, a second server and an associated second database, and a third server implemented as a communications port through which the different communications operators are accessed for the establishment of conversations with end clients. The system also envisages the use of personal access passwords for every application or group of applications.
