A method to investigate congestion in a computer network may include network devices to route data packets throughout the network. The method includes, for example, sending a probe packet to network devices from a source node to gather information about the traffic queues at each network device that is examined by the probe packet. A routing table at each network device that receives the probe packet is based on the gathered information for respective each traffic queue.

Network data congestion management probe system

A reliability system for a Converged Enhanced Ethernet network may include a plurality of end points each comprising a layer 4 transport layer, where each end point is connected to a data center bridging (DCB) layer 2 network. The system may also include an adaptor between the layer 4 transport layer and the DCB layer 2 network to translate at least one of flow and congestion control feedback signals, provided by at least one of the DCB network and the transport layer, to consolidated feedback signals for controlling transmission by the transport layer.

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.

Network data congestion management method

A method for allocating pending requests for data packet transmission at a number of inputs to a number of outputs of a switching system in successive time slots, including a matching method including the steps of providing a first request information in a first time slot indicating data packets at the inputs requesting transmission to the outputs of the switching system, performing a first step in the first time slot depending on the first request information to obtain a first matching information, providing a last request information in a last time slot successive to the first time slot, performing a last step in the last time slot depending on the last request information and depending on the first matching information to obtain a final matching information, and assigning the pending data packets at the number of inputs to the number of outputs based on the final matching information.
