Each receiver saves the marker prior to delivering data to an application, thereby designating a point in the data stream at which all preceding data is confirmed to have been delivered to the application. Thus, if a forwarding node fails, the receiver may request stream data from an alternate forwarding node by specifying to the alternate forwarding node to provide data starting from the marker. | 2009-07-09 |

20090175167 | Method of Reducing Network Congestion - In a method of reducing network congestion between a source computer and a destination computer, a receiving router receives a source quench message and determines whether originator of the source quench message is the destination computer or an intermediate router. If the receiving router determines the originator to be the destination computer, the receiving router forwards the source quench message to the source computer. If the receiving router determines the originator to be an intermediate router, the receiving computer determines if there is an alternative route from the receiving router to the destination computer. If the receiving router determines there is no alternative route from the receiving router to the destination computer, the receiving router forwards the source quench message to the source computer. If the receiving router determines there is an alternative route to the destination computer, the receiving router does not forward the source quench message to the source computer, and, going forward, routes packets to the destination computer by the alternative route. | 2009-07-09 |

The invention further describes a specific embodiment where all cross-correlating links are adjacent to each other, i.e., they terminate or originate in a common node. A mechanism is described to create an extended routing graph. This extended graph permits the use of standard polynomial time algorithms that simultaneously construct the optimal route and find the optimal route metric (such as shortest-path algorithms) also for the adjacent link cross-correlating case. | 2009-07-09 |
