Patent number: 7983287Abstract: Roughly described, a packet switching fabric contains a separate queue scheduler for each combination of an input module and a fabric output port. The schedulers may also be specific to a single class of service. Each queue scheduler schedules its packets without regard to state of other input queues and without regard to packets destined for other output ports. In an aspect, the fabric manages per-flow bandwidth utilization of output port bandwidth capacity by monitoring the same and asserting backpressure toward the queue scheduler for any thread that is exceeding its bandwidth allocation. In another aspect, a switching fabric uses leaky buckets to apply backpressure in response to overutilization of downstream port capacity by particular subflows. In another aspect, a switching fabric includes a cascaded backpressure scheme.Type: GrantFiled: May 14, 2008Date of Patent: July 19, 2011Assignee: Agere Systems Inc.Inventors: John T. Musacchio, Jean Walrand, Roy T. Myers, Jr., Shyam P. Parekh, Jeonghoon Mo, Gaurav Agarwal

Publication number: 20100098048Abstract: A method for hybrid media access control for vehicle communication is provided. The method divides a radio channel into time slots, which are predetermined time units, and sets terminals as owners or non-owners for the divided time slots to be able to access the channel. Accordingly, it is possible to reduce the probability of contention by distributed access to the slots and provide a MAC protocol having excellent performance.Type: ApplicationFiled: May 29, 2009Publication date: April 22, 2010Applicants: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE, KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Moonsoo KANG, Sangwoo Lee, Jeonghoon Mo, Hyun Jeong Yun, Kyeong-Soo Han, Hyun Seo Oh, Dong Yong Kwak, Jeongseok Ha

Patent number: 7480246Abstract: In one embodiment, data segments routed through a switch fabric are identified as being either a first or a second type. First and second counters are maintained for a destination node to characterize the transmission of data segments of the corresponding type within the switch fabric. For each first-type time period, all transmitted data segments are identified as being the first type. For each second-type time period, all transmitted data segments are identified as being the second type. The first- and second-type time periods are interleaved. The first counter is reset after termination of each first-type time period and the second counter is reset after termination of each second-type time period to correct for a possible error in characterizing the transmission of the data segments within the switch fabric during the corresponding time period.Type: GrantFiled: April 23, 2007Date of Patent: January 20, 2009Assignee: Agere Systems Inc.Inventors: Gaurav Agarwal, John T.
