Abstract: Described embodiments provide systems and methods for determining a scale for buffers of a session. A device may identify a round trip time (RTT) of a session with a client for which one or more of a plurality of buffers are provided. The device may detect an indication in advance of an activity on the client to access through the session. The device may determine, responsive to detecting the indication, a scale based at least on a type of the activity. The device may set a number for the plurality of buffers to provide for the session in accordance with the scale and the RTT.

Abstract: A client device includes resource caches, and a processor coupled to the resource caches. The processor receives resources from different resource feeds, and caches user interfaces (UI) of the resources from the different resource feeds, with at least one resource feed having a resource cache separate from the resource cache of the other resource feeds. Statuses of the resource feeds are determined, with at least one status indicating availability of the at least one resource feed having the separate resource cache. UI elements from the separate resource cache are retrieved for display in response to the at least one resource feed associated with the separate resource cache not being available.

Abstract: A virtual delivery appliance may communicate with a client device over a network to provide the client device with a virtualized session for a user. A processor may be configured to communicate with the client device over the network to perform a registration operation with a relying party. An application within the virtualized session may perform an authentication operation with the relying party to access a resource. The processor may be configured to forward an authentication challenge message to the client device in response to the application receiving the authentication challenge message from the relying party for the user to access the resource, and receive an authentication answer message in response to the authentication challenge message from the client device.

Abstract: Provided herein are systems and methods for providing insights or metrics in connection with provisioning applications and/or desktop sessions to end-users. Network devices (e.g., appliances, intermediary devices, gateways, proxy devices or middle-boxes) can gather insights such as network-level statistics. Additional insights (e.g., metadata and metrics) associated with virtual applications and virtual desktops can be gathered to provide administrators with comprehensive end-to-end real-time and/or historical reports of performance and end-user experience (UX) insights. Insights relating to an application or desktop session can be used to determine and/or improve the overall health of the infrastructure of the session, Citrix Virtual Apps and Desktops, the applications (e.g., remote desktop application) being delivered using the infrastructure, and/or the corresponding user experience.

The processor may also cause a second client computing device to independently stream the video from the media cloud source based upon the determined URL, and play the video at the second client computing device synchronously with playback of the video at the first client computing device based upon the playback control data, with the first client computing device being the controller for playback of the video at the second client computing device.

Abstract: A computing system may include a server, and a client computing device in communication with the server. The server may be configured to provide a corresponding virtual desktop instance for the client computing device. The computing system may include a local device to be coupled to a given client computing device and to be operable in a given virtual desktop instance associated with the given client computing device, thereby generating client initialization packets. The server may be configured to generate a server mapping table. The given client computing device may be configured to generate a client mapping table, replace a client packet with a client mapping ID number to define compressed client initialization packets, and send the compressed client initialization packets to the server. The server may be configured to replace the client mapping ID number with the client packet in the compressed client initialization packets based upon the server mapping table.

Abstract: A computing device may include a memory and a processor cooperating with the memory to access a session hosted by a remote computing device, and classify a group of data packets into first and second data packets. The first data packets may define reference points for reassembly of the group of data packets with the second data packets at their original positions in the group of data packets. The processor may further send the first and second data packets to the remote computing device via different channels with different rates of packet loss to enable reconstruction of the group of data packets at another device.

Abstract: Virtual application and desktop delivery may be optimized by supplying application metadata and user intent to the device between a client and a server hosting resources for the delivery. The data packets used to deliver the virtual application or desktop may be also tagged with references to the application. By supplying the metadata and tagging packets with the metadata, an intermediary network device may provide streams of data packets at the target QoS. In addition, the device may apply network resource allocation rules (e.g., firewalls and QoS configuration) for redirected content retrieved by the client out of band relative to a virtual channel such as the Internet. The network resource allocation rules may differ for different types of resources accessed. The device may also control a delivery agent on the server to modify communication sessions established through the virtual channels based on network conditions.

Abstract: A method may include storing and updating published resource entitlements for a plurality of client devices at a computing device. The method may also include using a plurality of virtual delivery appliances to receive connection requests from the client devices, with the connection requests including connection leases having associated resource entitlements the client devices are respectively permitted to access, and request validation of the connection leases from the computing device. At the computing device, responsive to validation requests from the virtual delivery appliances, the connection leases may be compared to the updated published resource entitlements and validated based thereon. At the virtual delivery appliances, the client devices may be provided with access to virtual sessions corresponding to the published resource entitlements responsive to the virtual session request validations from the computing device.

Abstract: Methods, systems, and apparatuses for discovering dynamic path maximum transmission unit (PMTU) between a sending computing device and a receiving computing device (e.g., a client device and a host device) are described herein. A sending computing device may iteratively transmit bursts of probe packets, each burst being defined by a search range between a maximum packet size and a minimum packet size. The sending computing device may iteratively update the search range based on the previous iteration until the search converges on the PMTU. When the PMTU is discovered, each of the computing devices may update their transport and presentation layer buffers based on the discovered PMTU without any other protocol level disruption. In a multi-path scenario, the computing device may discover PMTU for each of the paths and select a performance optimal path based on the individual PMTUs and other network characteristics such as loss, latency, and throughput.

Abstract: A method includes retrieving, by a workspace client on a computing device, a first set of resource associations from a workspace server. The first set of resource associations identify one or more data file-types executable by each application on a virtualization server. The method also includes generating, by the workspace client, from the first set of resource associations, a second set of resource associations. The second set of resource associations identify a subset of applications on the virtualization server operable to perform operations on each of the one or more data file-types. The method further includes obtaining, by a storage provider client on the computing device, the second set of resource associations. The storage provider client is configured to enable one or more applications on the virtualization server to execute at least one data file accessible from a storage provider.

The network resource allocation rules may differ for different types of resources accessed. The device may also control a delivery agent on the server to modify communication sessions established through the virtual channels based on network conditions.
