Abstract:
Various techniques of simple modifications to TCP/IP protocol & other susceptible protocols and related network's switches/routers configurations, are presented for immediate ready implementations over external Internet of virtually congestion free guaranteed service capable network, without requiring use of existing QoS/ MPLS techniques nor requiring any of the switches/routers softwares within the network to be modified or contribute to achieving the end-to-end performance results nor requiring provision of unlimited bandwidths at each and every inter-node links within the network.
Abstract:
There is described a method of sending CTI messages in a communications system. The method comprises assigning to each of a plurality of CTI messages a priority indicator selected from a plurality of different priority indicators, sending the plurality of CTI messages from a queue formed by the CTI messages such that the time interval between two messages sent from the queue depends upon the priority indicator assigned to the first of the two messages to be sent, whereby the time interval between messages being sent from the queue may vary.
Abstract:
A radio base station (104) is described herein that uses a delay reference timing (DRT) extension (402) located within a received high-speed downlink shared channel (HS-DSCH) data frame (110) to detect a buffering delay that is caused by large buffer build ups in transport nodes (112 and 114) that are located on a transport link (106) between a radio network controller (102) and the radio base station (104). In addition, the radio base station (104) can correct a problem if the detected buffering delay is too long by reducing the bit rate of a certain high-speed (HS) user flow or by reducing the maximum bit rate for all of the HS traffic which is going to be sent by the radio network controller (102) over the transport link (106) to the radio base station (104).

Abstract:
One or more flow control modules, implemented on various types of network topologies, provide a number of functionalities for controlling the flow of IP packets (such as TCP/IP packets) over a network connection. The flow control modules may be implemented within a sender and/or receiver or may be deployed into a network as a separate device without requiring significant additional resources.
Abstract:
Encapsulating packets into a frame includes receiving the packets at a station of a number of stations of a network. Each packet is associated with a delay requirement that reflects a deadline corresponding to at least one of the stations. The packets are directed to queues of the station. An available channel of the network is detected. It is determined that one or more packets at a queue are ready to be encapsulated into a frame in accordance with the delay requirements. The one or more packets are encapsulated into the frame for transmission using the available channel.
Abstract:
L’émetteur (4) mesure un délai de boucle minimum RTT min , le délai de boucle RTT représentant la durée entre l’envoi d’un paquet de données et la réception d’un accusé de réception correspondant, et la quantité Q de données préalablement émises par lui et acquittées durant une durée T, puis il estime le débit de réception E débit réc. à l’aide de la formule E Débit réc. = Q/T et calcule une nouvelle valeur du seuil d’évitement de congestion à l’aide de la formule ssthreh = RTT min .E débit réc. .
