| 20090080437 | Service selection in a shared access network using virtual networks - The present invention discloses a method and architecture for enabling multiple services or service providers to share the facilities of an access network infrastructure that provides physical connectivity to subscribers. | 03-26-2009 |
| 20100135304 | Method for applying macro-controls onto IP networks using intelligent route indexing - Systems and methods are described that manage routing information in an IP network using extensible indexing and use the indexing to control the network. The indexing and associated controls apply to any router within the routing domain. | 06-03-2010 |
| 20100313251 | Method and Apparatus for Coordinating a Change in Service Provider Between a Client and a Server with Identity Based Service Access Management - A method of configuring a network access device connected to an access network connected to a plurality of service networks, the network device having a first network address allocated to a subscriber of services of a first service provider provided by a first service network, with a new network address allocated to a second subscriber of services of either the first service provider, or a second service provider provided by a second service network. The method comprises the steps of: sending a request from the network access device to the access network with user credentials for the second subscriber requesting access to the first service provider or a change to the second service provider; receiving a response from the access network; and initiating a network address change request using a configuration protocol. In this manner, a second network address allocated to the second subscriber of services of either the first or second service providers is assigned to the network access device to enable the network access device to communicate data packets to the service network providing the selected service. | 12-09-2010 |
| 20110047252 | Adaptive Routing of Content Requests Using Multiple Anycast Addresses - A system includes a plurality of cache servers and a domain name server. Each of the cache servers is configured to respond to a content request. The plurality of cache servers is divided into a plurality of subsets and configured to respond to an anycast address for each subset to which the cache server belongs. The domain name server is configured to receive a request from a requester for a cache server address, identify an anycast address for a largest available subset, and provide the anycast address of the largest available subset to the requester. | 02-24-2011 |
| 20110134748 | Bulk Data Transport in a Network - A network is configured to utilize available bandwidth to conduct bulk data transfers without substantially affecting the successful transmission of time-sensitive traffic in the network. In order to avoid this interference, the packets carrying data for bulk data transfers are associated with a low priority class such that the routers of the network will preferentially drop these packets over packets associated with the normal traffic of the network. As such, when the normal traffic peaks or there are link failures or equipment failures, the normal traffic is preferentially transmitted over the bulk-transfer traffic and thus the bulk-transfer traffic dynamically adapts to changes in the available bandwidth of the network. Further, to reduce the impact of dropped packets for the bulk-transfer traffic, the packets of the bulk-transfer traffic are encoded at or near the source component using a loss-resistant transport protocol so that the dropped packets can be reproduced at a downstream link. | 06-09-2011 |
| 20110142054 | METHODS, APPARATUS AND ARTICLES OF MANUFACTURE TO MANIPULATE PACKET ROUTING - Example methods, apparatus and articles of manufacture to manipulate packet routing are disclosed. A disclosed example method includes extracting a destination address from a first packet, querying a route table based on the destination address to obtain a first label associated an egress router, querying the route table based on the destination address to obtain a second label associated with an interface of the egress router, forming a second packet from the first packet, the second packet including the first and second labels, and routing the second packet to the egress router based on the first label. | 06-16-2011 |
| 20110145409 | Method For Applying Macro-Controls Onto IP Networks Using Intelligent Route Indexing - Systems and methods are described that manage routing information in an IP network using extensible indexing and use the indexing to control the network. The indexing and associated controls apply to any router within the routing domain. | 06-16-2011 |
| 20110252156 | System and Method for Providing Information to Users of a Communication Network - A plurality of multimedia data streams that are being provided via an internet protocol (IP) network is received, wherein each multimedia data stream carries multimedia content. Real-time metadata relating to the plurality of multimedia data streams is generated based on the multimedia content. The metadata is provided in real-time in a metadata stream to a plurality of user devices, via the IP network. The plurality of multimedia data streams may be multicast within the IP network. The metadata may be multicast in real-time in a metadata stream to a plurality of user devices, via the IP network. | 10-13-2011 |
