摘要： The invention relates to a method and system for facilitating traversal of NATs. The method includes a terminal in a local network comprising a NAT of a first NAT type providing to a server an identification of the first NAT type. The method further includes the terminal receiving from the server NAT-related information for NATs of the first NAT type, where the NAT-related information for the NATs of the first NAT type enables the terminal to traverse the NAT. NAT-related information obtained by testing a NAT of a specific NAT type, such as e.g. a specific brand, model, and/or firmware version of a NAT, may be re-used for other NATs of the same type, irrespective of the local network in which those NATs are used, thus alleviating the need to separately test the NATs of the same type in each local network that contains these NATs.

摘要： System and method for making a vertical handover decision between first and second networks using a terminal configured to attach to both networks and a fixed point in either network. Both networks allow information flow between the terminal and the fixed point. When attached to the first network the terminal detects the second and compares a first bandwidth measurement, representing available bandwidth along a first path between the terminal and the fixed point, to a second bandwidth measurement representing available bandwidth along a second path between the terminal and the fixed point. The terminal maintains attach to the first network if the first bandwidth measurement is higher than the second bandwidth measurement and makes a decision to handover to the second network if the second band¬ width measurement is higher than first bandwidth measurement.

摘要： The invention relates to a node for communication between a first network and an second network and coupled to a controller in the second network via a first communication route. The node and controller form a virtualised home gateway platform. The node is arranged to access a second communication route and also to couple to the controller via the second communication route upon connection failure of the first communication route. This reconnects the node to the controller thereby maintaining a route for transmission of data streams and downloads into the home environment but also re-establishes control signalling within the virtualised home gateway platform and therefore also within the home network. A system for performing gateway functions between a first network and an second network, and a method of maintaining connection between a node and a controller, are also described.

摘要： A method is described for measuring capacity on a route in a network configured to carry reliable packet traffic, by identifying and matching at least two sets of at least one first and at least one second packets transmitted on the route, the at least one first packet being transmitted in a first direction and the at least one second packet transmitted in a direction in reverse direction to the first, by also registering times for the at least two sets, and by calculating capacity of the route dependent on packet size and registered times for the at least two sets. A network node is also described. The method is advantageous for use in home networks because it uses existing traffic and therefore allows probing past device firewalls and in this instance the network node can be a gateway device, or home gateway.

摘要： A method and system is described for delivering data streams in a network comprising devices connected to the network via adapters and wherein at least some of the devices are programmed to indicate priority of a data stream using priority parameter values of respective priority parameter types. One device in the network operates as a controller and the accompanying controller adapter is configured to perform priority enforcement on data streams according to all priority parameter types used within the datastreams in the network. A controller is also described and the controller can be a gateway configured to allow data streams into and out of the network. The method, system and controller find particular application in networks based on shared network segments, for example power line communication or networks based on coaxial cable.

摘要： A method is presented of probing a network using probing with a probe packet pair, the pair comprising a first probe packet (L1) and a second probe packet (L2), and wherein L1>L2. The L1 probe packet is transmitted before L2 and the probe packets are arranged to be back-to-back on the last link. Use of the method provides the capacity of the last link in the probed path. The method may be run from a gateway in a network to probe aspects of the network and is suitable for probing a domestic network behind a home gateway. A use for the method is also described.

摘要： A system for managing a data stream between first and second networks is described in which a node entity transmits a data stream addressed to a destination device in the second network and a gateway entity receives the data stream from the first network. The gateway entity identifies at least one characteristic of the destination device and transmits it to the node entity in the first network in such a way that the characteristic is relatable to the data stream. The node entity receives the characteristic of the destination device from the gateway entity and relates it to the data stream and performs Quality of Service management on the data stream based on the at least one characteristic. A gateway device and a method of managing a data stream are also described. The system, gateway, node and method extend the application of QoS performance and management.
