摘要： The SSL VPN session failover solution of the appliance and/or client agent described herein provides an environment for handling IP address assignment and end point re-authorization upon failover. The appliances may be deployed to provide a session failover environment in which a second appliance is a backup to a first appliance when a failover condition is detected, such as failure in operation of the first appliance. The backup appliance takes over responsibility for SSL VPN sessions provided by the first appliance. In the failover environment, the first appliance propagates SSL VPN session information including user IP address assignment and end point authorization information to the backup appliance. The backup appliance maintains this information. Upon detection of failover of the first appliance, the backup appliance activates the transferred SSL VPN session and maintains the user assigned IP addresses. The backup appliance may also re-authorize the client for the transferred SSL VPN session.
摘要翻译：本文描述的设备和/或客户端代理的SSL VPN会话故障切换解决方案提供了一种在故障转移时处理IP地址分配和终点重新授权的环境。可以部署设备以提供会话故障转移环境，其中当检测到故障转移条件时，第二设备是第一设备的备份，诸如第一设备的操作失败。备份设备负责第一个设备提供的SSL VPN会话。在故障切换环境中，第一个设备将SSL VPN会话信息（包括用户IP地址分配和终点授权信息）传播到备份设备。备份设备维护此信息。在检测到第一个设备的故障切换后，备份设备会激活传输的SSL VPN会话并维护用户分配的IP地址。备份设备还可以重新授权客户端传输的SSL VPN会话。

摘要： The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. The acceleration program of the present invention is automatically installed and executed on a client in a manner transparent to and seamless with the operation of the client. An appliance may intercept a request of the client to establish a communication session or connection with a server, and transmit the acceleration program to the client. In some cases, the appliance determines whether the application being accessed by the client can be accelerated and only provides the acceleration program if the application can be accelerated. Upon receipt of the acceleration program, the client automatically performs a silent installation of the acceleration program and executes the acceleration program upon completion of the installation.

摘要： The present invention is directed towards systems and methods for dynamically redirecting on a client communications of the client with a server to bypass an intermediary that is determined to be unavailable for such communications. An acceleration program on the client establishes a transport layer connection between the client and server, and intercepts communications of the client to the server. The transport layer connection may be established via an intermediary, such as a gateway, proxy or appliance. If the client-side acceleration program determines the intermediary is not available for communicating by the client to the server, the acceleration program automatically establishes a second transport layer connection to the server in order to bypass the intermediary. The acceleration program then transmits the intercepted communications of the client via the second transport layer connection to the server. The acceleration program may automatically redirect intercepted communications of the client to the server transparently to any user or application of the client.

摘要： The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. In one embodiment, the client-side acceleration functionality is provided by an acceleration program that performs a transport layer connection multiplexing technique for improving performance of communications and delivery of a remotely-accessed application. The acceleration program establishes a transport layer connection from the client to the server that can be used by multiple applications on the client, or that is otherwise shared among applications of the client. The acceleration program multiplexes requests from one or more applications via the same transport layer connection maintained by the acceleration program. As such, the acceleration program can utilize the idle time of one application in using the transport layer connection to service a request of a second application through the same transport layer connection.
摘要翻译：本发明涉及用于在客户端上动态部署和执行加速功能以提高远程访问应用的性能和传送的系统和方法。在一个实施例中，客户端加速功能由执行用于改善远程访问应用的通信和传送的性能的传输层连接复用技术的加速程序提供。加速程序建立从客户端到服务器的传输层连接，可以由客户端上的多个应用程序使用，也可以在客户端应用程序之间共享。加速程序通过由加速程序维护的相同传输层连接复用来自一个或多个应用程序的请求。因此，加速程序可以利用一个应用在使用传输层连接中的空闲时间来通过相同的传输层连接来服务于第二应用的请求。

摘要： The present application relates to systems and methods for managing of Real Time Stream Protocol (RTSP) sessions by an intermediary located between a client and a server. An intermediary located between a client and a server receives a response from the server to a request of the client to setup a media stream. The response may include a first session identifier established by the server. The intermediary may encode a port of the server and an internet protocol address of the server into the first session identifier to form a second session identifier. The intermediary may modify the response to identify the second session identifier as the session identifier provided by the server. The intermediary may transmit the modified response to the client responsive to the request of the client to setup the media stream.
