Patent number: 11076027Abstract: Techniques for selecting a network communications protocol based on network topology and/or network performance are described. A first application executing on a first computer system obtains a distance characteristic of a network coupling the first computer system to a second computer system. The first application selects a network communications protocol from a plurality of network communications protocols based on the distance characteristic of the network. The first application and the second application connect with the selected network communications protocol. In some embodiments, the distance characteristic of the network may be based on topological or performance characteristics of the network.Type: GrantFiled: December 3, 2018Date of Patent: July 27, 2021Assignee: Amazon Technologies, Inc.Inventors: Nathan William Sharp, Christopher Magee Greenwood, Pavel Labovich, Colin Williams, Ashritha Nagavaram

Patent number: 8943512Abstract: A system for facilitating virtualization of a heterogeneous processor pool includes a processor allocation component and a hypervisor, each executing on a host computer. The processor allocation component identifies a plurality of physical processors available for computing and determines a set of flags, each of the set of flags identifying a type of functionality provided by each of a subset of the plurality of physical processors. The hypervisor, in communication with the processor allocation component, allocates, to at least one virtual machine, access to one of the subset of the plurality of physical processors.Type: GrantFiled: December 20, 2012Date of Patent: January 27, 2015Assignee: Citrix Systems, Inc.Inventors: Vincent Hanquez, Jonathan James Ludlam, Richard William Sharp, David Jonathan Scott

Patent number: 8856486Abstract: A technique deploys a copy of a disk image from source storage to target storage. The technique involves identifying a particular disk image to be copied from the source storage to the target storage. The technique further involves performing a comparison operation between a first disk image list which lists disk images on the source storage and a second disk image list which lists disk images on the target storage to generate a common disk image list which lists a set of common disk images on both the source and target storage. The technique further involves transferring, from the source storage to the target storage, a set of data portions representing differences between the particular disk image and a common disk image listed on the common disk image list. The set of data portions in combination with the common disk image form a deployed copy on the target storage.Type: GrantFiled: October 31, 2011Date of Patent: October 7, 2014Assignee: Citrix Systems, Inc.Inventors: Richard William Sharp, David Jonathan Scott, Jonathan James Ludlam
