摘要： A software-defined network includes a database (105) that is accessible to a controller system (108, 109) of the software defined network and also to network elements (101-014) of the software defined network. The controller system determines configuration data and delivers it to the database. Each network element retrieves its part of the configuration data from the database and implements the retrieved part of the configuration data into its own configuration system that enables the network element to operate as a part of the software-defined network. The commonly used database facilitates maintaining the congruence between the network elements and the controller system of the software-defined network.

摘要： In a data communication system according to the invention the functionality of the gateway device is distributed in a data communication network thereby reducing the need to direct the data traffic from and to terminals (212, 213, 214) through a single point in the data communication network. A first data communication device (207) is arranged to make, through signalling, second data communication devices (204, 205, 206) capable of directing the data communications of the terminals to the starting points of the respective logical data communication tunnels (215, 216, 217). This way there is no need for all logical data communication tunnels to start from, or depending on the direction, to end at, the same point in the data communication network.

摘要： To transfer a communication session from a first data source to a second data source, the following operations are carried out when a radio terminal is handed over from a first base station to a second base station: the session settings and status information related to the communication session are transferred (503) to be used in conjunction with the second data source, a first portion of the payload data related to the communication session is sent (504) in accordance with the session settings from the first data source to the radio terminal via the second base station, and the next portion of the payload data which according to the status information still has to be sent to the radio terminal during the communication session is sent (506) in accordance with the session settings from the second data source to the radio terminal via the second base station. The transfer of the communication session is not visible to the radio terminal because the transmission of payload data continues uninterrupted and the session settings, such as TCP socket parameters, remain unchanged during the transfer.

摘要： In a system, the functionality is decentralized in a data transmission network so that the need of communications produced by and addressed to data terminals to pass by way of a single point in the data transmission network is diminished. A first data transmission installation is adapted to signal second data transmission installations, each of which is part of a ring-shaped data transmission topology, to be capable of building logical data transmission tunnels directed to the data terminals. Thereby, all the logical data transmission tunnels need not commence or, depending on the direction, terminate at the same point of a data transmission network. In addition, the data transmission installations present in a ring-shaped data transmission topology need not necessarily be taught routing information in order to enable each of these data transmission installations to send data transmission frames to be transmitted to another one of these data transmission installations.
