Patent number: 8462626Abstract: The present system uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals, or messages, are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. Messages indicative of an end user routing ID (RID) are identified and the information extracted for user with successive messages. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.Type: GrantFiled: August 20, 2007Date of Patent: June 11, 2013Assignee: Ciena CorporationInventors: Gautam Desai, Subrahmanyam Dravida, Satya V. Gupta, Kiran M. Rege, Manas Tandon, Ravi S. Kumar, DeQuan Wu

Patent number: 7924883Abstract: The present system uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. The intelligent network elements can be co-located with or replace the standard network elements to take advantage of existing network configurations. A tree-and-branch network architecture is therefore established in which each intelligent network element is assigned a routing ID employed in the point-to-point transmissions while leaving legacy analog signals unimpeded. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.Type: GrantFiled: August 20, 2007Date of Patent: April 12, 2011Assignee: Ciena CorporationInventors: Subrahmanyam Dravida, Dey V. Gupta, Frederick Peralta, Kiran M. Rege, Manas Tandon

Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. The intelligent network elements are co-located with or replace the standard network elements to take advantage of existing network configurations. The standard network elements are selectively replaced by the intelligent network elements in an incremental approach. A tree-and-branch network architecture is established in which each intelligent network element is assigned a routing ID employed in the point-to-point transmissions while leaving legacy analog signals unimpeded.Type: GrantFiled: July 12, 2005Date of Patent: November 16, 2010Assignee: Ciena CorporationInventors: Subrahmanyam Dravida, Dev V.

Patent number: 7788357Abstract: A method for delivering content over a network, the method involving: receiving a request to establish a session at a future time T1 over the network, the requested session for transferring content between a content server and a subscriber's equipment; reserving network capacity necessary to support the requested future session; acknowledging to the requestor that network resources have been reserved for said requestor for time T1; and when current time reaches time T1, causing the requested session to be set up for transferring content between the content server and the subscriber's equipment.Type: GrantFiled: January 24, 2005Date of Patent: August 31, 2010Assignee: Camiant, Inc.Inventors: Yusun Kim Riley, Manas Tandon, Pramod Kalyanasundaram

Publication number: 20080209494Abstract: Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. As this cable plant was deployed in a tree and branch topology, data transmissions may be susceptible to noise, variable transmission loss and frequency dispersion, particularly in the upstream direction. Further, due to the tree and branch topology, homes at the far end of the network experience much greater loss than do the homes that are near to the headend/ONU. The present system, which uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router.Type: ApplicationFiled: August 20, 2007Publication date: August 28, 2008Inventors: Subrahmanyam Dravida, Dey V.
