    摘要： Methods, apparatus and systems for effecting Virtual Machine (VM) platform communication loopback and enabling user initiated network port failover. Network communications in platforms employing VMs and having multiple network ports accessible to the VMs are configured to be routed such that communications between VMs in the platform are looped back within the platform, thus not require routing through an external switch. This is facilitated via an Intelligent Channel Bonding Driver that dynamically enforces inter-VM traffic to ensure internal loopback within the same physical port. In another aspect, a user is enabled to initiate failover of a network port on a platform employing a Virtual Machine Manager and a plurality of VMs, wherein updated configuration information is sent to disable Virtual Function (VF) drivers associated with the network port.

    摘要： Technologies for ensuring data integrity for multi-packet operations include a computing device and a remote computing device communicatively coupled via a network. The computing device is configured to perform a segmentation offload operation on an original network packet, compute a hash value on the payload of each segmented payload of the original network packet, and store the hash value and an indication into the segmented network packet that indicates the hash value is stored in the segmented network packet. The remote computing device is configured to extract the indication and the hash value from a received network packet in response to determining the indication indicates the hash value is stored in the segmented network packet, compute a hash value on the payload of received network packet, and determine an integrity of the payload based on a comparison of the extracted hash value and the computed hash value.
