A method and apparatus for communicating USB data. In one embodiment, the method comprises receiving, by an optimizer executing on a computer and communicatively coupled between a USB storage driver (USBSD) and a USB hub controller driver (UHCD), an SCSI command; transmitting, by the optimizer in response to receiving the SCSI command, the SCSI command to the UHCD; generating, by the optimizer, an SCSI command completion; transmitting, by the optimizer, the SCSI command completion to the USBSD; receiving, by the optimizer, SCSI data associated with the SCSI command completion; transmitting, by the optimizer in response to receiving the SCSI data, the SCSI data to the UHCD; generating, by the optimizer after transmitting the SCSI data, an optimized SCSI status message; transmitting, by the optimizer, the optimized SCSI status message to the UHCD; and transmitting, by the optimizer responsive to an SCSI status completion, the SCSI Status completion to the USBSD.

Apparatus and method for optimizing USB-over-IP data transactions

In one embodiment a method for communicating data comprises receiving, by a traffic manager between a plurality of virtual machines (VMs) and a network interface, (a) first data from a first VM in the plurality of VMs and en route via a first client computer to a first device, and (b) second data from a second VM in the plurality of VMs and en route via a second client computer to a second device; determining first attributes of the first data that provide a first communication requirement; determining second attributes of the second data that provide a second communication requirement; determining, based on available bandwidth of the network interface, a communications schedule associated with cumulative bandwidth of the first and second communication requirements; and transmitting, according to the communications schedule, the first data to the first client computer and the second data to the second client computer.
