Time filter

Source Type

The present application is directed to methods and systems for redirecting write requests issued by trusted applications to a secure storage. Upon redirecting the write requests, the data included in those requests can be stored in the secure storage area of a client computer. In some embodiments, the methods and systems can include determining whether an application issuing the request is a trusted application that requires data to be stored in a secure storage repository. Upon making this determination, a filter driver can identify a secure storage area on a client computer and can redirect the write request to this secure storage. In other embodiments, the filter driver may deny requests of trusted applications to write to unsecure storage areas.


A technique manages medical image data. The technique involves receiving an original medical imaging study that includes a set of medical images and embedded protected patient information. The technique further involves performing a protected patient information removal operation which generates a cloud-storable medical imaging study from the original medical imaging study. The cloud-storable medical imaging study includes the set of medical images but omitting the embedded protected patient information. The technique further involves storing the cloud-storable medical imaging study in a cloud-based medical image repository among other cloud-storable medical image studies. The cloud-based medical image repository is external to the computerized device and public network accessible.


A system for allocating a different class of service to each network connection in a plurality of network connections, where each network connection corresponds to one or more virtual channels. The system can include a plurality of virtual channels that connect a first computer and a second computer. Each virtual channel can service at least a portion of the network traffic generated using a remote-display protocol. The system can also include a plurality of network connections, where each network connection corresponds to at least one of the virtual channels. Each network connection of the system can have an assigned port number and an assigned class of service that corresponds to a transmission priority level. The class of service assigned to each network connection can be unique from the classes of service assigned to other network connections.

A method and system for operating an application with multiple modes are described. A plurality of applications may be presented to a user on a mobile device and one of the displayed applications may be selected. The selected application may have one or more contexts that are determined based on one or more operational parameters. For example, a context for the selected application may be that the application is configured to access an enterprise account. Based on the context, the selected application may be run on the mobile device in one of a plurality of operations modes. The operation modes may comprise managed, unmanaged, and partially managed modes, among others.


The present disclosure is directed to methods and systems of providing a user-selectable list of disparately hosted applications. A device intermediary to a client and one or more servers may receive a user request to access a list of applications published to the user. The device may communicate to the client the list of published applications available to the user, the list comprising graphical icons corresponding to disparately hosted applications, at least one graphical icon corresponding to a third-party hosted application of the disparately hosted applications, the third party hosted application served by a remote third-party server. The device may receive a selection from the user of the at least one graphical icon. The device may communicate, from the remote third party server to the client of the user, execution of the third party hosted application responsive to the selection by the user.

One or more aspects of this disclosure may relate to using a configurable server farm preference for an application, desktop or other hosted resource. Additional aspects may relate to moving server farm workloads based on the configurable server farm preference. Further aspects may relate to performing reboot cycles, a reboot schedule and on-demand rebooting. Yet further aspects may relate to staggering individual machine reboot operations over a specified period of time and performing reboot operations such that some machines are available for user sessions during a reboot cycle.

The present disclosure is directed to systems and methods for controlling delivery of a resource. An intermediary device may establish a connection to deliver a resource hosted on at least one server to a client using a remoting protocol. The remoting protocol may define one or more channels in the connection for delivering or enabling one or more features of the resource to the client. The device may identify the one or more channels, and may identify the one or more features of the resource. The device may determine a policy for controlling access of the client to at least a first feature of the resource. The device may control access of the client to the first feature by modifying a first channel of the one or more channels according to the determined policy.

The present disclosure is directed towards systems and methods for measuring round trip time (RTT) in network devices between the device and an endpoint. A network device may be deployed as an intermediary to provide many security and visibility functions. For measuring the server side RTT between the network device and host, the intermediary device identifies the packet that has been sent by the client when it initiated the RTT measurement. The network device remembers the moment T1 when it sees this packet. The host (e.g., the server) will respond to this with a packet that contains the response. The intermediary device remembers the moment T2 when it sees this response. Server side RTT is calculated by the network device as T2T1. For measuring the client side RTT the network device and client, the intermediary device identifies the packet that the host sends to initiate measurement of RTT. As per the HDX protocol, the client will respond immediately with a new packet or with a bit set in any packet being sent to the host. Just as for server side RTT, the intermediary device can identify these packets and measure the times to calculate the client side RTT.


A client computer requests a resource from an ISP/OSP. The ISP/OSP maintains multiple instances of the resource. In deciding to which instance of the resource to route the client computer, a resource selection server takes network routability information into account. Geographic proximity, resource utilization, network utilization, and/or maintenance of peering agreements may also be taken into account in selecting the instance of the resource.
