| 20110064212 | POWER BACKUP SYSTEM - An electrically powered node of a telecommunications system has a battery power backup associated with its power control unit. Under normal conditions it is maintained fully charged by means of trickle currents from the mains power feeds to each of a number of mains—connected customer equipments, by way of the “final drop” to the distribution point. These trickle currents are controlled by the respective power control units to prevent overcharging. Using an electrical copper connection provided in parallel with the fibre connection, a battery backup can also be maintained in nodes further towards the exchange. The feeds are reversible, so that if a power outage removes the power supply from the customer premises, a “lifeline” plain telephone service between the exchange and the telephone handset is maintained using the local battery backup in the remote nodes. By limiting the service to simple telephony, the battery power can be sufficient to maintain the service for a reasonable duration. The power management systems can be used to transfer charge from one battery to another over the network according to the usage, or remaining life, of each battery. | 03-17-2011 |
| 20110047268 | Switching system - An Ethernet access connection connects a user access point to an access node in the network. The access connection comprises a passive coupler, by means of which a further access connection can be provided between the user access point and a second access node, such that data can be exchanged over each access connection between the user access point and the network. This duplication ensures that communication is not severed if the access connection is breached. To avoid interference at the destination terminal between the two resulting identical data streams, the access nodes giving access to the destination terminal are controlled such that only one of them forwards data to the destination access point, with the capability to switch to the other one in the event of a loss of connection between the access node and user access point. | 02-24-2011 |
| 20110026934 | TRANSMISSION OF BROADBAND SIGNALS - The invention is concerned with the transmission of broadband signals onto to a telephony connection having constraint profile limiting the maximum allowed power as a function of frequency. As a result, broadband signals can be delivered using low power equipment to a telephony line whilst respecting the constraint profile associated with that line. | 02-03-2011 |
| 20110026399 | ADMISSION CONTROL AND ROUTING IN A PACKET NETWORK - Embodiments of the invention provide a network management sub-system which is preferably logically separate from the routing nodes (including gateway nodes) of a network. The network management sub-system receives load information relating to present packet flows on existing predetermined paths in the network, and when a request for admittance of a new packet flow is received, is able to make a decision as to whether the new flow should be both: i) admitted to the network; and ii) on to which path; in substantially the same process step. This is possible because the admission control and routing algorithms are integrated into a single process, the result of which provides both an admission control decision as well as a routing decision at the same time. By performing such an operation in a management sub-system which is separate from the routing nodes, there is no need for such functionality to be duplicated in nodes across the network, and instead the routing nodes are relieved of the burden of having to make such decision themselves. As a consequence, the network nodes can be kept simpler, and network control can be retained by the network operator in the management sub-system. | 02-03-2011 |

Connection status messages are transmitted over the primary routing. If these are not detected by the network, it causes traffic to the user device to be diverted over the backup routing to the second network address. It also transmits instructions to the user device to route outgoing traffic by the same secondary route. The secondary route is identified from network tolopogy data stored by the network control server. | 06-17-2010 |
| 20100115085 | COMPUTER NETWORK - A peer-to-peer network operating in accordance with a service-oriented architecture is disclosed. The peers in the network request services from one another and each keeps a record of the quality of service they receive from the other peers. The peers share quality of service information with one another in order to take advantage of the improvement in the overall efficiency of the use of resources in the network offered by such information sharing. However, the invention provides a further improvement in that peers do not report the quality of service offered by the peers they have received the best quality of service from. This is found to increase the overall level of service still further since it prevents the peers converging on a favourite service provider and thereby overloading it. The invention finds particular application in distributed applications which dynamically select a Web Service to perform a function at run-time. | 05-06-2010 |

| 20080285859 | Method and System for Processing Video Data - In an intelligent video surveillance system, video processing software performs a number of operations on video data received from a camera, including foreground extraction, shadow removal and object tracking. The foreground extraction stage classifies each pixel of a received frame as representing either foreground or background. Since shadow regions can be wrongly classified as foreground, a two-branch shadow removal operation is employed, comprising weak shadow removal ( | 11-20-2008 |
| 20080278711 | Distributed Backscattering - The present invention relates to a method for detecting or inferring a physical disturbances on a communications link, in particular by using distributed backscattering. The method includes the steps of: transmitting test signals onto a link; receiving test signals returned from a remote portion of the link; performing a function on the returned test signals; and in dependence on at least one characteristic of the combination signal, inferring the presence of a disturbance. The test signal are returned by a process Rayleigh backscattering along the fibre, so existing fibre installations can be used without requiring a mirror to be specifically introduced. | 11-13-2008 |
