20110173352 | Power Reduction on Idle Communication Lanes - A method for communication includes establishing a full-duplex communication link between first and second nodes. The link includes multiple first lanes for conveying first communication traffic in a first link direction and multiple second lanes for conveying second communication traffic in a second link direction. Signals are exchanged between the first and second nodes to indicate a requested change in lane activity in the first link direction. Responsively to the signals, a number of the first lanes that are active is changed so that the first node conveys the first communication traffic to the second node over a first number of the first lanes, while the second node conveys the second communication traffic to the first node over a second number of the second lanes, which is different from the first number. | 07-14-2011 |

20150103667 | DETECTION OF ROOT AND VICTIM NETWORK CONGESTION - A method in a communication network includes defining a root congestion condition for a network switch if the switch creates congestion in the network while switches downstream are congestion free, and a victim congestion condition if the switch creates the congestion as a result of one or more other congested switches downstream. A buffer fill level in a first switch, created by network traffic, is monitored. A binary notification is received from a second switch, which is connected to the first switch. A decision whether the first switch or the second switch is in a root or a victim congestion condition is made, based on both the buffer fill level and the binary notification. A network congestion control procedure is applied based on the decided congestion condition. | 04-16-2015 |
