| 20080291845 | Inter-Domain Map-Finder - Link information is obtained about new or changes links in a communications system having a plurality of domains. The link information concerning a link between a first and a second domain comprises at least four pieces of information, domain identity of the first domain, domain identity of the second domain, link end identifier for a first end of the link, and link end identifier for a second end of the link. The link information is cascaded through the communications system by providing the link information stepwise from one domain to an adjacent domain. This is achieved by spreading the obtained link information to adjacent domains and by distributing link information received from adjacent domains to further adjacent domains. Preferably, the link information is compiled and access to the compiled link information is provided for creation of a system link map. | 11-27-2008 |
| 20100145925 | METHOD AND ARRANGEMENT FOR ENABLING COMMUNICATION WITH A CLIENT DEVICE - A method and arrangement for enabling communication with a client device by making a currently valid communication address of the device publicly available. The client device sends a freely composed connectivity key to a publicly available connectivity server, the connectivity key being searchable by means of web searching using a search engine. The client device also sends connectivity parameters to the connectivity server including at least the communication address, which then becomes publicly available in the connectivity server by web searching of the associated connectivity key. If a new currently valid communication address is obtained for the client device, the connectivity parameters can be updated by sending the new communication address to the connectivity server. | 06-10-2010 |
| 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 |
| 20110228791 | NETWORK NODE - The invention relates to a network node arranged to provide an end user of a network terminal in a network with an access link to an external network comprising at least one external network interface, a control unit, and at least one internal network interface, the network node being arranged to be connected between the network and the external network. The network node is characterized in that it the control unit is arranged to deactivate and re-activate the at least one internal network interface towards the network terminal in the network in order to trigger a dynamic host configuration protocol request from the network terminal such that a new IP configuration can be established for the network terminal. The invention also relates to a method for use in a network node and a computer program product. | 09-22-2011 |
