| 20080273465 | Method of switching fabric for counteracting a saturation tree occurring in a network with nodes - The invention relates to a method and a switching fabric for counteracting a saturation tree occurring in a network with nodes. The method comprises the steps of generating at a local node where a congestion emerges a first congestion information; sending the first congestion information to at least one upstream node; responsive to one received first congestion information comparing the content of the received first congestion information with a pre-sent local status based on a set of predefined rules in order to identify at least one packet stream causing the congestion, and generating a second congestion information comprising the identified at least one packet stream causing the congestion; and sending the second congestion information to at least one further upstream node from where the identified at least one packet stream was received. | 11-06-2008 |

| 20090141630 | METHOD FOR MONITORING DATA CONGESTION IN A COMPUTER NETWORK WITH MULTIPLE NODES AND METHOD FOR CONTROLLING DATA TRANSMISSION IN THE COMPUTER NETWORK - A method for monitoring data congestion in a computer network with multiple nodes and for controlling data transmission in the computer network. The method includes generating a congestion notification by the node which detects a data congestion and transmitting the congestion notification to the data source which is involved in the data congestion. The method also includes generating in the data source a congestion value which indicates how severe the data congestion is, and storing in a worst case array of the data source those congestion values which indicate the most severe data congestions. | 06-04-2009 |
| 20090147679 | NETWORK DEVICE AND METHOD FOR OPERATING NETWORK DEVICE - A network device including at least one rate-limited-queue and multiple timer modules, the network device being operable to receive and/or transmit data flows from and/or to a communication network. Each data flow includes multiple data packets. The network device being further operable to limit the predetermined transmission rate of the respective data flow dependent on whether a data congestion in the communication network has been indicated, in such a way, that in case of an indicated congested communication network a respective timer module is associated to each of the data flows and/or each group of data flows, whereas the data packets of the respective data flows and/or group of data flows are buffered in the rate-limited-queue. Each data packet in the rate-limited-queue is transmitted with a limited transmission rate predetermined by the respectively associated timer module when the data packet is at the head of the rate-limited-queue. | 06-11-2009 |
| 20090296577 | METHOD AND APPARATUS FOR END-TO-END NETWORK CONGESTION MANAGEMENT - The invention provides a method and apparatus for network congestion management. The method includes inserting a probe frame into data traffic in the network from a first endpoint in the network, reflecting the probe frame from a second endpoint in the network back to the first endpoint, receiving the reflected probe frame at the first endpoint via the network, determining a round-trip delay based on flow of the probe frame through the network, and throttling network traffic according to the determined delay to manage network traffic congestion. | 12-03-2009 |

| 20080247411 | Method to operate a crossbar switch - A method is described to operate a crossbar switch comprising a crossbar fabric with N sending and M receiving ports, with port cards connected to at least one sending and/or receiving port each of the crossbar fabric, said crossbar switch further comprising a control unit connected with the port cards via discrete control channel links, wherein C ports are clustered on a single receiving port card so that such a receiving port card in a single time-step can receive up to C data cells from C sending port cards simultaneously. According to said method the control channel links are used to relay up to C acknowledgements between at least one receiving port card and at least one sending port card. | 10-09-2008 |

| 20110242976 | METHOD, COMMUNICATION NETWORK AND DATACENTER FOR TRAFFIC MANAGEMENT IN A COMMUNICATION NETWORK - Method, communication network and datacenter for data traffic management in a communication network. The invention provides a method for data traffic management in a communication network. The method first includes setting up a first communication path for a first data communication and transmitting data from a source of the first data communication to a destination of the first data communication. Then, features of a saturation tree representing a congestion of data transmission in the first data communication are monitored and a data rate of the first data communication along the first communication path is adapted based on the monitored features. The present invention further provides a datacenter and a communication network. | 10-06-2011 |

| 20110032825 | MULTIPATH DISCOVERY IN SWITCHED ETHERNET NETWORKS - A network switch device receives a communication packet having a source MAC address s and a destination MAC address d at a switch port p. Then, the network switch device determines whether a valid routing table entry (s, p) exists, there by indicating that the source MAC address s is reachable via a switch port p. The network switch device further determines for the destination MAC address d whether there is at least one switch port q for which a valid routing table entry (d, q) exists, there by indicating that d is reachable via a switch port q. When the routing table entries (s, p) and (d, q) exist, the network switch device routes the communication packet to the switch port q. | 02-10-2011 |

| 20100220749 | METHOD AND ARRANGEMENT FOR LOCAL SYCHRONIZATION IN MASTER-SLAVE DISTRIBUTED COMMUNICATION SYSTEMS - A communication system which consists of several modules—operating in parallel on segments of a packet—to increase speed and handling capacity. One module acts as master, the others are slave modules controlled by control signals derived by the master module. It is important that in each module the data segment and the respective control signal of each packet are correctly synchronized, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference. | 09-02-2010 |

| 20110261696 | NETWORK DATA CONGESTION MANAGEMENT PROBE SYSTEM - A system to investigate congestion in a computer network may include network devices to route data packets throughout the network. The system may also include a source node that sends a probe packet to the network devices to gather information about the traffic queues at each network device that receives the probe packet. The system may further include a routing table at each examined network device that is based upon the gathered information for each respective traffic queue. | 10-27-2011 |
| 20110261697 | NETWORK DATA CONGESTION MANAGEMENT SYSTEM - A system to manage data congestion in a computer network may include network devices to route data packets throughout the network. The system may also include a source node that sends data packets to any of the network devices. The system may further include a routing table at each network device that is updated by the source node, and the route the data packets are sent by any network device is based upon each respective routing table. | 10-27-2011 |
