Patent number: 8179887Abstract: A network system, having an array of processing engines (“PEs”) and a delay line, improves packet processing performance for time division multiplexing (“TDM”) sequencing of PEs. The system includes an ingress circuit, a delay line, a demultiplexer, a tag memory, and a multiplexer. After the ingress circuit receives a packet from an input port, the delay line stores the packet together with a unique tag value. The delay line, in one embodiment, provides a predefined time delay for the packet. Once the demultiplexer forwards the packet to an array of PEs for packet processing, a tag memory stores the tag value indexed by PE number. The PE number identifies a PE in the array, which was assigned to process the packet. The multiplexer is capable of multiplex packets from PE array and replacing the packet with the processed packet in the delay line in response to the tag value.Type: GrantFiled: February 1, 2008Date of Patent: May 15, 2012Assignee: Tellabs Operations, Inc.Inventors: Naveen K. Jain, Venkata Rangavajjhala

Patent number: 8165097Abstract: A transmission method performed by a mobile station for random access channel (RACH) burst transmission diversity gain is provided. According to the method, by combining and using switching diversity by beam forming, frequency hopping, and power ramping, the probability that when the speed of a mobile station is low, the mobile station falls into a deep fading environment is lowered, thereby increasing the probability of detecting an RACH signature of the base station. Also, by using the transmission parameters (subbands, precoding matrixes, power, etc.) which are used for successful transmission of an RACH burst, for transmission of a successive user packet data, reliable transmission of the successive user packet data can be performed.Type: GrantFiled: April 19, 2007Date of Patent: April 24, 2012Assignee: Electronics and Telecommincations Research InstituteInventors: Hyo-Seok Yi, Il-Gyu Kim, Young-Jo Ko, Kapseok Chang, Hyeong-Geun Park, Young-Hoon Kim, Seung-Chan Bang

Patent number: 8072901Abstract: A technique efficiently sends probe packets from a source to a target in a destination prefix over two or more paths of a computer network. According to the novel technique, the source, e.g., configured for optimized edge routing (OER), sends probe packets (probes) over all available paths (exits) to the target in the destination prefix in order to select a preferred path based on received responses to the probes, e.g., according to one or more policies. Once the preferred path is selected, the source sends probes to that target only over the preferred path until a trigger occurs, such as, e.g., an out of policy (OOP) event, a policy change, or an optional timer-based trigger. Upon being triggered, the source again probes all paths to reselect the preferred path.Type: GrantFiled: September 29, 2005Date of Patent: December 6, 2011Assignee: Cisco Technology, Inc.Inventors: Dana Blair, Larry R. Metzger

Patent number: 8073015Abstract: A communication system includes communication protocols that allow a single network or multiple neighboring networks to increase resource sharing and reduce mutual interference and increase their overall throughput. Various protocols apply to homogenous networks in which all power line communication (PLC) devices of multiple networks are interoperable with respect to full power line communication in a common PHY (specifications, signaling capabilities, modulation scheme, coding scheme, bandwidth, etc.) and to heterogeneous networks in which devices of some PLC networks are not interoperable with PLC devices of other PLC networks with respect to full power line communication given that the devices of the different networks do not employ a common PHY. With respect to heterogeneous networks, a protocol is provided to enable coexistence via a signaling scheme common to all of the devices of the network that allows resource sharing between the devices of the multiple heterogeneous networks.Type: GrantFiled: December 31, 2008Date of Patent: December 6, 2011Assignee: Panasonic CorporationInventors: Stefano Galli, Akio Kurobe, Masato Ohura

Patent number: 8072885Abstract: In order to allow priority transfer (fluctuation) over VLL packets while keeping each contracted bandwidth constantly, a leaky bucket model is expanded to have a threshold 1509 for permitting transmission of a packet (e.g. a WFQ packet) other than an LLQ packet and a threshold 1501 (larger than the threshold 1509) for permitting transmission of the LLQ packet (two-threshold leaky bucket model). In this manner, even when a WFQ cannot be transmitted, an LLQ can be transmitted with priority. In addition, while the total bandwidth of the WFQ and LLQ, i.e. the bandwidth of the VLL contains fluctuation, the contracted bandwidth can be complied with. The circuit of the model is provided in LLQ and WFQ transmission appointed time calculating circuits so as to calculate respective transmission appointed times so that an LLQ/WFQ is selected and a packet is selected based on the times considering priority.Type: GrantFiled: February 4, 2008Date of Patent: December 6, 2011Assignee: Alaxala Networks CorporationInventor: Takeshi Aimoto

Patent number: 8054806Abstract: In a wireless network, for example, an LTE network, the context information relating to a mobile terminal UE is transmitted to a plurality of network nodes eNB 2, 3 and 4 from a source network node, eNB 1. One of the eNB 2 is a handover target node and also reserves resources for the UE in anticipation of receiving it after handover. The other eNBs 3 and 4 do not reserve resources. In the event of radio link failure, the UE may attach to one of the designated eNBs 3 and 4 that have not reserved resources, but that do recognize the UE because they have received its context. The method reduces the likelihood of the UE needing to go via the time consuming IDLE state while only reserving resources at a handover target eNB.Type: GrantFiled: August 7, 2008Date of Patent: November 8, 2011Assignee: Alcatel LucentInventors: Osman Aydin, Hajo-Erich Bakker, Heidrun Grob-Lipski, Markus Gruber, Stephen Kaminski, Klaus Keil, Sudeep Kumar Palat

Patent number: 8040884Abstract: A method, system, computer program product and apparatus are presented to enable a L2 network device, such as a bridge or switch, to control the flow of a multicast data stream to a connected router in response to control messages received from the router by the L2 network device. By controlling the flow of multicast data streams in this manner, there will be a corresponding reduction in wasted bandwidth due to unnecessary transmission of these multicast data streams and a reduction in processing overhead by the router due to analysis and dropping of unnecessary multicast frames. In one aspect of the present invention, the router can generate the control messages in response to receiving a data frame in a multicast data stream from the L2 network device.Type: GrantFiled: August 8, 2005Date of Patent: October 18, 2011Assignee: Cisco Technology, Inc.Inventors: Senthil Arunachalam, Sundher Narayanaswamy, Isidoros Kouvelas, Ishan Wu, Toerless Eckert
