Abstract: A method for operating a communication network includes a communication network providing a sender of a distributed real-time application and a receiver of the distributed real-time application with a communication connection, the distributed real-time application defining a minimum operable data rate. The sender periodically transmits data packets to the receiver via the provided communication connection at a data rate higher than the defined minimum operable data rate. The sender steadily determines a currently available bitrate of the communication connection, and adjusts the data rate to a data rate lower than the determined currently available bitrate by a data rate offset defined by the distributed real-time application. A node of the communication network learns the defined data rate offset and provides a guaranteed minimum bitrate of the communication connection higher than a booked minimum bitrate of the communication connection by the learned data rate offset.

Abstract: A method for selecting a route for outgoing data traffic includes receiving, by a communication terminal, at least one user equipment route selection policy rule, which comprises a traffic descriptor and at least one route selection component. The communication terminal detects a traffic-related information item which is related to at least one outgoing data unit. The communication terminal selects a user equipment route selection policy rule from the at least one received user equipment route selection policy rule, where a traffic descriptor of the selected user equipment route selection policy rule is associated with the detected traffic-related information item on the basis of a matching table that is stored in the communication terminal. The communication terminal selects a route for the at least one outgoing data unit on the basis of a route selection component of the selected user equipment route selection policy rule.

Abstract: A method for operating a communication network is provided. The communication network provides a sender of a distributed real-time application and a receiver of the distributed real-time application with a communication connection, the distributed real-time application defining a minimum operable data rate. The sender periodically transmits data packets to the receiver via the provided communication connection at a data rate higher than the defined minimum operable data rate. The sender steadily determines a currently available bitrate of the communication connection and adjusts the data rate to the determined currently available bitrate. A node of the communication network steadily learns a distance of the data rate from the minimum operable data rate, and the node prevents the currently available bitrate from lowering when the learned distance is smaller than a predetermined threshold distance.

Abstract: A method for operating a communication network includes: receiving, by a business support system of a resource reservation system, a reservation request, the reservation request indicating a Quality of Service (QoS) for an upcoming connection to be provided at a time distance from a reservation by the communication network for a terminal device and an application or service accessed by the terminal device via the upcoming connection; checking, by a bookkeeper decision engine of the resource reservation system, whether the business support system has availability for the indicated QoS; in response to confirming the availability for the indicated QoS, sending, by the bookkeeper decision engine, a reservation confirmation; and providing, by the communication network, the upcoming connection with the indicated QoS assigned for the terminal device at the time distance from the reservation.

Abstract: A system for packet-based scheduling for Transmission Control Protocol (TCP) sessions or User Datagram Protocol (UDP) sessions includes: a first bonding module comprising a first scheduling module and at least two access interfaces connected to at least one transport network, wherein the first bonding module is configured to be connected to a user device, wherein a TCP tunnel is configured via each of the access interfaces which terminates at a second bonding module, and wherein the first scheduling module is configured to schedule and distribute data packets via the TCP tunnels towards the second bonding module. The second bonding module comprises a second scheduling module and at least one access interface connected to each of the at least one transport network, wherein the second bonding module is configured to be connected to a server and to schedule and distribute data packets via the TCP tunnels towards the first bonding module.
