Abstract: Methods, apparatus and software for implementing enhanced data center congestion management for non-TCP traffic. Non-congested transmit latencies are determined for transmission of packets or Ethernet frames along paths between source and destination end-end-nodes when congestion along the paths is not present or minimal. Transmit latencies are similarly measured along the same source-destination paths during ongoing operations during which traffic congestion may vary. Based on whether a difference between the transmit latency for a packet or frame and the non-congested transmit latency for the path exceeds a threshold, the path is marked as congested or not congested. A rate at which the non-TCP packets are transmitted along the path is then managed as function of a rate at which the path is marked as congested.

Abstract: Method and apparatus for minimizing on-die memory in pull-mode switches. A disaggregated edge switch (DSW) includes a local communication interface including a plurality of outer ports configured to be coupled to a plurality of local hosts or servers via respective outer links, and a network interface configured to couple to at least one remote apparatus via a respective inner port and link. Data is transferred between the local hosts/servers using pull-mode transfers under which a receiver port “pulls” data from a local source port. The use of pull-mode data transfers between the local host/servers is managed by a scheduler so as to minimize the amount of buffers space for these local data transfers. Techniques are also disclosed for extending pull-mode data transfers using the Ethernet protocol over Ethernet links.

The at least one indication may be provided, at least in part, prior to the entirety of the at least one portion of the data being available for the processing by the at least one data processor. The at least one data processor may begin the processing in response, at least in part, to the at least one indication. Many alternatives, variations, and modifications are possible.

Abstract: Methods and apparatus for implementing notification by network elements of packet drops. In response to determining a packet is to be dropped, a network element such as a switch or router determines the source of the packet and returns a dropped packet notification message to the source. Upon receipt of notification, networking software or embedded hardware on the source causes the dropped packet to be retransmitted. The notification may also be sent from the network element to the destination computer to inform networking software or embedded logic implemented by the destination computer that the packet was dropped and notification to the source has been sent, thus alleviating the destination from needing to send a Selective ACKnowledge (SACK) message to inform the source the packet was not delivered.

Abstract: Real-time car driving simulator for providing to passengers of a vehicle the feeling they are currently driving the vehicle. The simulator includes devices combined together for providing the same functionalities of a video camera unit, an inertial measurement unit, user interface(s), a processor, and monitor(s). A passenger attempts to mimic the vehicle operator's actions while the operator is operating the vehicle and the vehicle is in motion, and an assessment of the comparison is provided to the passenger. The processor analyzes output of control components controlled by the vehicle operator provided by a vehicle control component position system and simulated control of the vehicle's movement being effected by the passenger using the user interface(s) to enable output indicative of accuracy of the simulation of the control of vehicle movement by the passenger relative to the actual control of the vehicle movement by the operator to be provided to the passenger.

Abstract: Methods, apparatus, and networks configured to manage network congestion using packet recirculation. The networks employ network elements (e.g., Rbridges in Layer 2 networks and switches/routers in Layer 3 networks) that are configured to support multi-path forwarding under which packets addressed to the same destination may be routed via multiple paths to the destination. In response to network congestion conditions, such as lack of availability of a non-congested port via which a shortest path to the destination may be accessed, a packet may be routed backward toward a source node or forwarded toward a destination along a non-shortest path. The network elements may employ loopback buffers for looping packets back toward a source via the same link the packet is received on.
