Patent number: 7609624Abstract: Improved network design techniques are provided. For example, a technique for designing a protection capacity to be reserved in a network comprises the following steps/operations. One or more link capacities associated with a network topology are obtained. The network is assumed to have no pre-existing working traffic. A capacity partition including a working capacity portion and a protection capacity portion is determined for at least one link in the network topology. The protection capacity portion is reserved for rerouting working traffic upon a failure and enabling control over the number of backup tunnels, associated with the at least one link, on which working traffic can be rerouted. Determining the capacity partition substantially guarantees at least one of a minimal failure restoration time and a minimal overbuild. A minimal overbuild may include an overbuild equivalent to no more than two times an overbuild required for an optimal solution.Type: GrantFiled: May 3, 2004Date of Patent: October 27, 2009Assignee: Alcatel-Lucent USA Inc.Inventors: Mansoor Ali Khan Alicherry, Randeep Singh Bhatia

Patent number: 7453796Abstract: Improved network design techniques are provided. More particularly, the invention provides network design techniques that support fast restoration. In one aspect of the invention, a technique for designing a protection capacity to be reserved in a network comprises the following steps/operations. Link capacities associated with a network topology and existing working traffic in the network are obtained. Capacity partitions are determined for links in the network topology. Each of at least a portion of the capacity partitions comprise a protection capacity portion and a working capacity portion that equals or exceeds the existing working traffic on a corresponding link, such that upon a failure on the link, the working traffic on the link is rerouted over a pre-provisioned detour path using the protection capacity portion on one or more links on the detour path. Further, the capacity partition determination step/operation substantially guarantees protection for existing working traffic in the network.Type: GrantFiled: June 4, 2004Date of Patent: November 18, 2008Assignee: Lucent Technologies Inc.Inventors: Mansoor Ali Khan Alicherry, Randeep Singh Bhatia, Yung-Chun Wan

Patent number: 7449677Abstract: An optical encoder includes a code strip having a first side, a second side, a first track comprising indicia thereon, and a second track comprising indicia thereon. The code strip is moveable along a displacement path with respect to the optical encoder. A light source positioned on the first side of the code strip directs light toward the code strip. A first detector element is positioned on the second side of the code strip and is generally aligned with the first track of the code strip. A second detector element is positioned on the second side of the code strip and is generally aligned with the second track of the code strip. The second detector element is also positioned so that the second detector element is located a spaced distance along the displacement path from the first detector element.Type: GrantFiled: June 4, 2007Date of Patent: November 11, 2008Assignee: Avago Technologies ECBU IP (Singapore) Pte. Ltd.Inventors: Kean Foong Ng, Sze Kuang Lee, Hock Aun Tan, Weng Fei Wong, Wee Jin Yeap, Chee Foo Lum, Kok Hing Fo, Toshiya Hataguchi, Randeep Singh A/L Amarjit

Patent number: 6246885Abstract: A novel and improved digital FM audio processor for use in a dual-mode communication system selectively operative in either FM or code division multiple access (CDMA) modes. Analog voice or voice-band data is input to a speech encoder/decoder (CODEC) which converts the analog signal to a digital signal. The digital FM signal is read from the CODEC, filtered, compressed, up-sampled and combined with a transponded SAT signal and then modulated for RF transmission. On the receive side, the FM analog signal is received, demodulated, down-sampled, expanded, and filtered before being converted to the proper format (&mgr;-law, a-law, or linear) for the speech CODEC. The CODEC then converts the digital FM audio signal into an analog waveform for conversion to sound. By performing the FM audio processing digitally, the same digital signal processing (DSP) firmware may integrated on the same application specific integrated circuit (ASIC) which is capable of performing audio processing of both FM and CDMA audio signals.Type: GrantFiled: June 11, 1998Date of Patent: June 12, 2001Assignee: Qualcomm IncorporatedInventors: Peter J.
