Abstract: A data unit sender and method of controlling a data unit sender are presente d, in which a time-out monitoring procedure implements a first, longer time-out period (SRTO), and a second, shorter time-out period (QRTO), where a retransmission is executed after the shorter time-out period if the availabl e transmission capacity value for unsent data is greater or equal to the size of a designated data unit that is to be retransmitted as a result of said time- out monitoring procedure.

Abstract: A method and device for determining a parameter (RTO) associated with a retransmission time-out feature in a data unit transmitter implementing a protocol (TCP) that provides an acknowledgment feature and a retransmission time-out feature, where according to one aspect decreasing values of the rou nd trip time (RTT) are treated differently with respect to their influence on a mean deviation parameter (RTTVAR) than increasing values of the round trip time, where according to another aspect weight values (g, h, w) used in the determination of the parameter (RTO) are chosen such that at least one of th em is time variable, and where according to a further aspect the parameter (RTO ) is also calculated on the basis of a value (SR) indicative of the number of spurious time-outs in the communication.

Abstract: In a data unit oriented communication between a sender and a receiver in accordance with a predetermined communication protocol, where said communication protocol prescribes that the sender in a communication divides an amount of data to be sent into one or more data units, and the receiver in said communication acknowledges the correct receipt of data units by returning acknowledgment data units to the sender, Methods and devices are described for detecting whether an acknowledgment data unit received by said sender corresponds to an original transmission or a retransmission.

Abstract: Communication method and system for transmitting data partitioned into a plurality of data packets between at least two communication units (CU1, CU2, CU4) using a communication network (N). During temporary interruptions of transmission of data packets via the communication network some of the transmitted data packets are lost. The invention allows to avoid the loss of data packets due to temporary interruptions of the communication network by determining at the sending data processing device, based on information received from the communication network, which data packets are lost or will be lost during transmission due to a temporary interruption of the communication network. The method can be used for data transmission via mobile communication networks and an "Internet". To allow a retrieval of lost data packets, data packets scheduled for transmission can be temporarily stored in a temporary storage devices. Transmission of packets, retransmission and other services needed for data communication can be performed by an appropriately modified TCP/IP protocol set.

Abstract: Un método de gestión del tráfico de red que comprende: - que un equipo (10) de usuario reciba paquetes de datos entrantes de uno de varios portadores (52, 54); - que el equipo (10) de usuario detecte un nuevo flujo en los paquetes de datos entrantes recibidos, incluyendo los paquetes de datos entrantes del nuevo flujo una primera tupla de cinco elementos del Protocolo de Internet, incluidas una dirección de origen y una dirección de destino; - en respuesta a la detección del nuevo flujo, que el equipo (10) de usuario genere automáticamente un filtro (62, 64) de paquetes que opera en función de que una segunda tupla complementaria de cinco elementos del Protocolo de Internet incluya una dirección de origen igual a la dirección de destino de la primera tupla de cinco elementos del Protocolo de Internet y una dirección de destino igual a la dirección de origen de la primera tupla de cinco elementos del Protocolo de Internet; - por medio del filtro (62, 64) de paquetes, que el equipo (10) de usuario detecte paquetes de datos salientes que incluyan dicha segunda tupla de cinco elementos del Protocolo de Internet y encamine los paquetes de datos salientes detectados que tengan dicha segunda tupla de cinco elementos del Protocolo de Internet al mismo portador (52, 54) del que se reciben los paquetes de datos entrantes que tienen dicha primera tupla de cinco elementos del Protocolo de Internet, en el que dicha detección, dicho encaminamiento de los paquetes de datos salientes, y dicha generación automática del filtro (62, 64) de paquetes son activados selectivamente en función de una señal (4) de control.
