20080291920 | SYSTEM AND METHOD FOR MANAGING COMMUNICATIONS - A system and method for managing communications is disclosed. A system that incorporates teachings of the present disclosure may include, for example, a communication device having a controller element to transmit a packet along a logical tunnel established through an internet service provider, wherein the route of the packet is managed according to a MPLS label of the packet and a VRF routing table. Additional embodiments are disclosed. | 11-27-2008 |
20090016361 | SYSTEM AND METHOD FOR ESTABLISHING COMMUNICATIONS BETWEEN PACKET-SWITCHED NETWORKS - A system and method for establishing communications between packet-switched networks is disclosed. A system that incorporates teachings of the present disclosure may include, for example, a communication device having a controller element to transmit a packet along a logical tunnel established through an Internet Service Provider (ISP) network. The packet is encoded with a Virtual Circuit (VC) label by a local Ethernet network operating independent from the ISP network. The VC-label of the encoded packet is substantially undetectable by one or more network elements of the ISP network while in route through the logical tunnel. Additional embodiments are disclosed. | 01-15-2009 |
20090055241 | System and Method for Estimating a Qualiifed Impression Count for Advertising Data in a Communication System - A method and system for estimating a qualified impression count in a communication network, the method comprising receiving at a server, impression quality factors data comprising subscriber device state data indicative of a degree of active advertising data viewing, subscriber device type data indicative of a type of subscriber device receiving the advertising data and subscriber type data indicative of a type of subscriber viewing the advertising data; sorting the impression quality factors data into impression quality factors categories data; applying weights to the sorted impression quality factors categories data; accumulating the weighted impression quality factors categories data into the impression quality factors categories; applying unique curves to at least two of the accumulated impression quality factors categories data to generate curve adjusted impression quality factors categories data; correlating the curve adjusted impression quality factors categories data with advertising quality criteria data; and estimating the qualified impression count from the correlation. | 02-26-2009 |
20090296576 | SYSTEM AND METHOD FOR MEASUREMENT-BASED ADAPTIVE CACHING OF VIRTUAL CONNECTIONS - Reducing connection overhead in a communications network includes reusing at least one cached communication channel connecting a source and a destination. The at least one cached communication channel is cached for a variable duration. | 12-03-2009 |
20110075572 | ROBUST MULTICAST BROADCASTING - A method and system for multicasting IPTV channels includes using both a designated and a redundant network routing device. When the designated routing device detects that an MCDN network connection to an IPTV multicast source is unavailable, the designated routing device reduces its designation priority to a lower value. A message is sent to the redundant routing device with an instruction to increase its designation priority to a higher value. After the designation priorities have been modified, the designated routing device may serve as a new redundant routing device, while the redundant routing device may serve as a new designated routing device. The routing devices may remain in the new configuration, even after interrupted network connections are restored. | 03-31-2011 |
20110075663 | LOAD BALANCING MULTICAST NETWORK TRAFFIC USING VIRTUAL CHANNELS - A method and system for multicasting Internet-protocol television (IPTV) channels is disclosed. In order to receive desired IPTV channels, a first-hop router (FHR) may send a join message to a last-hop router (LHR) establishing multiple paths across a backbone network. The join message may specify mapping at least one virtual IPTV channel to a plurality of multicast channels, along with the desired IPTV channels. The multicast channels may then be transmitted in a round-robin manner over the multiple paths from the LHR to the FHR. A number of virtual IPTV channels may be modified in response to determining a loading profile over the multiple paths to maintain a balanced load among the multiple paths. | 03-31-2011 |
20130308639 | ROBUST MULTICAST BROADCASTING - A method and system for multicasting IPTV channels includes using both a designated and a redundant network routing device. When the designated routing device detects that an MCDN network connection to an IPTV multicast source is unavailable, the designated routing device reduces its designation priority to a lower value. A message is sent to the redundant routing device with an instruction to increase its designation priority to a higher value. After the designation priorities have been modified, the designated routing device may serve as a new redundant routing device, while the redundant routing device may serve as a new designated routing device. The routing devices may remain in the new configuration, even after interrupted network connections are restored. | 11-21-2013 |
20140160977 | SYSTEMS, METHODS, AND ARTICLES OF MANUFACTURE TO DETERMINE CONNECTIVITY - Systems, methods, and articles of manufacture to determine connectivity are disclosed. An example method includes identifying, with a processor, a radio network controller serving a NodeB based on a configuration of the NodeB; identifying, with the processor, a set of intermediate nodes forming a pathway between the radio network controller and the NodeB; and storing the pathway between the radio network controller and the NodeB based on the radio network controller and the intermediate nodes. | 06-12-2014 |
