| 20100150009 | Passive Monitoring Of Network Performance - The present invention relates to methods and arrangements to measure network performance. The method comprises the following steps:—Transmitting via a communication network (IP) payload packets ( | 06-17-2010 |
| 20100333160 | SEGMENTATION OF MULTICAST DISTRIBUTED SERVICES - The present invention relates to methods and arrangements to optimize bandwidth usage in a Multicast Services Control System (MSCS) for digital information transport. The system comprises a service provider (Server) and service receivers (STB | 12-30-2010 |
| 20110090811 | Available Bandwidth Estimation in a Packet-Switched Communication Network - A system and method for determining end-to-end available bandwidth of a path in a packet-switched communication network. A multi-rate packet chirp injector injects probe traffic packets at different probing rates, u, into the network utilizing a probe chirp. A receiver samples time separation of the probe traffic packets to generate time-separation samples, which are used to calculate relative inter-packet separation strain, ε, samples at different probing rates. An Expectation-Maximization, EM, analyzer utilizes an EM algorithm to identify useful strain ε samples and to estimate parameters of a line l | 04-21-2011 |
| 20110176429 | METHOD, ARRANGEMENT AND SYSTEM FOR MONITORING A DATA PATH IN A COMMUNICATION NETWORK - A probing method, arrangement, and system for estimating a condition, such as available bandwidth, of a data path in a communication network including multiple nodes are described. A probe-packet sender node transmits probe packets with a sent inter-packet separation and a time-to-live towards an intermediate node. Control message packets are generated by the intermediate node when the time-to-live expires. The probe-packet sender node receives the control message packets and calculates a received inter-packet separation. An estimate of the data path condition can be generated based on the sent inter-packet separation and the received inter-packet separation. | 07-21-2011 |
| 20110211588 | GATEWAY WITH HTTP PROCESSING - Embodiments of the present invention relate to an apparatus and method for providing an end user of a network terminal in a local network with an access link to an external network. According to an embodiment of the present invention, a network node further includes a control unit arranged to transmit a local hypertext transfer protocol (HTTP) response including detailed information to at least one network terminal in said local network using an earlier original HTTP request towards said external network made by said at least one network terminal in the local network. | 09-01-2011 |
| 20110216646 | RESIDENTIAL GATEWAY FOR PROVIDING BACKUP INTERFACE TO EXTERNAL NETWORK - The invention relates to a residential gateway for providing an end user of a network terminal in a residential network with access to an external network, said residential gateway comprising at least one network terminal interface arranged to provide an internal connection to said network terminal and an external network interface arranged to provide a first external connection to said external network. The residential gateway is characterized in that it comprises a secondary external network interface arranged to establish a second external connection with a mobile radio communications network in order to provide a backup access path to said external network, and a control unit arranged to activate said secondary external network interface, if not already activated, in response to detecting a loss of network connectivity over said first external connection, and forward data traffic between said residential network and said external network through said activated secondary external network interface. The invention also relates to a method for use in a residential gateway and a computer programme product. | 09-08-2011 |
| 20110252120 | CONFIGURATION OF A NETWORK NODE USING CAPTIVE MODE - The invention relates to a network node arranged to provide an end user of a network terminal in a local network with an access link to an external network, said network node is arranged to be connected between said local network and said external network. The network node is characterized in that it comprises a control unit arranged to in response to receiving a first triggering information, switch said network node from a normal operational mode into a captive mode, in which said control unit is further arranged to intercept any request from said network terminals to said external network, resolve said request to the IP address of the network node in the local network such that gateway information to the end user of said network terminals is provided. The invention also relates to a method for use in a network node and a computer program product. | 10-13-2011 |
| 20110292800 | Systems and Methods For Controlling Data Transmission Rates - The present application discloses systems and methods for adapting the rate at which the packets are transmitted. In one embodiment, the method includes: (a) receiving a packet; (b) determining whether the packet is high priority packet or a low priority packet; and (c) determining whether a transmission rate value, which defines the maximum rate or maximum average rate at which the node should transmit the low priority packets, should be adjusted, wherein the determination is based, at least in part, on whether at least some number of high priority packets and/or bits was received since a point in time; and (d) adjusting the transmission rate value if it is determined in step (c) that the transmission rate value should be adjusted. | 12-01-2011 |
| 20110292946 | Virtualization Platform - The invention relates to a visualization platform ( | 12-01-2011 |
