Patent number: 7623532Abstract: Enhanced Cable Modem Termination System (CMTS) functionality, including programmable digital domain modulators and demodulators for dynamic channel assignment, is incorporated into Fiber Nodes (FNs) or mini Fiber Nodes (mFNs), yielding enhanced Fiber Nodes (eFNs). These eFns distribute CMTS functionality deep into Hybrid-Fiber-Coax Networks (HFCN) rather than centralizing the CMTS functions within a single location. Moving the cable modem terminations closer to the subscribers shortens the analog RF paths required to support cable modems. Communication of both subscriber data and CMTS control data is performed over Ethernet-compatible packet networks between the field-based CMTSs and an upstream facility (e.g., the Head End), which includes an Internet gateway. Packet data for multiple subscriber cable modems is easily compressed and merged over common network paths, reducing cabling plant complexity and increasing bandwidth utilization.Type: GrantFiled: October 27, 2006Date of Patent: November 24, 2009Assignee: Juniper Networks, Inc.Inventors: Valentino Liva, Alok Sharma, Lance Smith, James Yee

Patent number: 7623537Abstract: A network device and system are provided. The network device may include a chassis configured to receive a line card and an input/output (I/O) card that operatively connects to a network via cabling. The chassis may include a bus structure. The bus structure may include an I/O interface to couple to a chassis interface of the I/O card, and a line card interface to couple to a chassis interface of the line card using a connector away that includes at least one RF conductor which may be associated with a set of connectors configured to shield the at least one RF conductor.Type: GrantFiled: June 21, 2006Date of Patent: November 24, 2009Assignee: Juniper Networks, Inc.Inventors: Valentino Liva, Alok Sharma, Lance Smith, James Yee

Publication number: 20090268749Abstract: A Cable Modem Termination System (CMTS) is partitioned into Line Cards, I/O Cards, and a midplane to provide enhanced Reliability, Availability, and Serviceability. Each I/O Card provides a cabling interface for coupling an assigned Line Card to other portions of a Hybrid-Fiber-Coax Network. A plurality of RF signals is coupled via connectors between each Line Card and a corresponding I/O Card, via the midplane. This permits a Line Card to be removed for servicing without requiring recabling of the corresponding I/O Card. Preferably, a rectangular-multi-pin collinear connector-cascade (Line Card jack, midplane double-plug, and I/O Card jack) is used to couple the plurality of RF signals. The connector-cascade is configured with protective RF ground pins adjacent and surrounding each of a plurality of RF signal pins.Type: ApplicationFiled: July 9, 2009Publication date: October 29, 2009Applicant: Juniper Networks, Inc.Inventors: Valentino LIVA, Alok Sharma, Lance Smith, James Yee

Patent number: 7599671Abstract: A wireless network device includes a signal receiving module that receives an RF signal, and a signal processing module that includes an automatic gain control (AGC) module and that generates control signals when a gain of the AGC module changes based on the RF signal. The network device includes a control module that selectively measures N time intervals between one of adjacent and non-adjacent control signals, wherein N is an integer greater than 1, and that selectively determines that the RF signal is a radar signal when the N time intervals are substantially equal.Type: GrantFiled: December 9, 2005Date of Patent: October 6, 2009Assignee: Marvell World Trade Ltd.Inventors: Milind Kopikare, Hui Yao Lin, James Yee, Chuong Vu

Publication number: 20080089300Abstract: A method of configuring an ad-hoc wireless network between an authenticator and a plurality of wireless devices seeking authentication includes assigning a wireless device as the authenticator and receiving a first setup message transmitted from a first device seeking authentication to the authenticator and initiating a first handshake process between the authenticator and the first device seeking authentication. The method also includes receiving a second setup message transmitted from a second device seeking authentication to the authenticator. The second setup message is received by the authenticator prior to completion of the first handshake process. The method further includes initiating a second handshake process between the authenticator and the second device seeking authentication. The second handshake process is initiated prior to completion of the first handshake process. Moreover, the method includes completing the first handshake process and completing the second handshake process.Type: ApplicationFiled: September 18, 2007Publication date: April 17, 2008Applicant: Marvell International Ltd.Inventor: James Yee
