    Abstract: Provided are systems and methods for reliable, out-of-order receipt of packets. In some implementations, provided is an apparatus configured to communicate with a network and a host device. The apparatus may receive packets over the network at a receive queue. The packets may originate from a source on the network, and may be received out of order. The apparatus may further, for each received packet, identify a transport context associated with the source and a destination of the packet, and determine whether the packet can be accepted. Upon determining that the packet can be accepted, the apparatus may further identify the one receive queue at which the packet was received; determine a user application to receive the packet, transfer the packet from the one receive queue to a buffer in host memory, and identify an order in which the packet was received with respect to other packets.

    Abstract: Generally described, physical computing devices in a virtual network can be configured to host a number of virtual machine instances. The physical computing devices can be operably coupled with offload devices. In accordance with an aspect of the present disclosure, a security component can be incorporated into an offload device. The security component can be a physical device including a microprocessor and storage. The security component can include a set of instructions configured to validate an operational configuration of the offload device or the physical computing device to establish that they are configured in accordance with a secure or trusted configuration. In one example, a first security component on the offload device can validate the operational computing environment on the offload device and a second security component on the physical computing device can validate the operational computing environment on the physical computing device.

    Abstract: Disclosed herein are techniques for classifying input network packets evenly into a plurality of classes. An apparatus includes an input port configured to receive a plurality of network packets. The apparatus also includes processing logic configured to receive the plurality of network packets from the input port and classify each packet of the plurality of network packets. For each packet, whether a condition is met is determined, a most recently used hash operation is selected when the condition is not met or a new hash operation is selected when the condition is met; and the selected hash operation is performed on the packet using at least a portion of the packet as an input value to classify the packet. The most recently used hash operation and the new hash operation are configured to classify packets having the same input value into different classes.
