Abstract: 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.

Abstract: A method and system for enabling management of a plurality of messages in a communication network is provided. The method includes measuring an in-load and an out-service corresponding to a plurality of switching-nodes in the communication network. The method further includes marking at least one message in a switching-node with an Explicit Congestion Notification (ECN) to form at least one Precise ECN (PECN)-message, if at least one predefined criterion corresponding to a switching-node evaluates to true. Each PECN-message is encoded with measurements of the in-load and the out-service corresponding to the switching-node. Thereafter, one or more management functions are performed to modify egress of the plurality of messages from a source-node. The source-node transmits the plurality of messages to a destination-node through the switching-node.

Abstract: A system and method for generating a computation graph corresponding to a communication graph and a network topology graph for a communication network interconnected using switch-elements is provided. Computation is placed in switch-elements of the computation graph. The method includes determining one or more operator-switch-elements for a computation level of the computation graph corresponding to one or more preceding-computation-level operand elements using span vector representation of the network topology graph. The method further includes selecting a last-computation-level operator-switch-element corresponding to a root-compute-node. The method allows computation to be placed inside a network to meet resource availability constraints.

Abstract: A method and system for managing flow of a plurality of packets in a lossless communication network interconnected by a plurality of switching-nodes is provided. The method includes creating a plurality of virtual-queues. Each virtual-queue corresponds to an output port of a switching-node. Thereafter, each packet is assigned to a virtual-queue. A packet is assigned to a virtual-queue based on information stored in a header of the packet.
