Patent number: 8990654Abstract: In conventional Backplane Ethernet systems, data is transmitted over two pairs of copper traces in one direction using a PAM-2 scheme and a baud rate of 10.3125 GHz, giving an effective bit rate of 10.3125 Gbps. The rate at which data can be transmitted in Backplane Ethernet systems, while still being reliably received, is typically limited by ISI caused by the dispersive nature of the copper traces, frequency dependent transmission losses caused primarily by skin effect and dielectric loss of the copper traces, and cross-talk from adjacent communication lines. The present invention is directed to systems for overcoming these and other signal impairments to achieve speeds up to, and beyond, twice the conventional 10 Gbps limit associated with Backplane Ethernet systems.Type: GrantFiled: December 20, 2013Date of Patent: March 24, 2015Assignee: Broadcom CorporationInventors: William Bliss, Vasudevan Parthasarathy

Publication number: 20150081865Abstract: A system for lossless switching of traffic in a network device may be implemented when a network switch is integrated into a gateway device, or with any other data source. A processor of the gateway device may receive queue depth information for queues of the network switch. The processor may prevent data from being transmitted to congested queues of the network switch, while allowing data to be transmitted to uncongested queues. In this manner, data loss can be avoided through the network switch for data sourced from the gateway device, such as audio-video data retrieved from a hard drive, audio-video data received from a tuner, etc. Furthermore, re-transmission at higher layers can be reduced. Since the subject system observes congestion for each individual queue, only traffic destined to that particular, congested, queue is affected, e.g. paused. Traffic to non-congested queues is not affected, regardless of traffic class or egress port.Type: ApplicationFiled: November 5, 2013Publication date: March 19, 2015Applicant: BROADCOM CORPORATIONInventors: Predrag KOSTIC, Darren Duane NEUMAN, David WU, Anand TONGLE, Rajesh Shankarrao MAMIDWAR, Milomir ALEKSIC
