Patent number: 8954595Abstract: 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 buffering 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 and buffers requests of the client based on determining a difference between a rate of consumption of responses received by the client from a server and a rate of production of requests transmitted by the client to the server. As such, the acceleration program can throttle transmissions of the client if the client's rate of consumption falls behind the rate of submission of requests.Type: GrantFiled: December 30, 2005Date of Patent: February 10, 2015Assignee: Citrix Systems, Inc.Inventors: Prabakar Sundarrajan, Junxiao He, Sergey Verzunov, Charu Venkatraman, Anil Shetty

Patent number: 8856777Abstract: 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.Type: GrantFiled: September 2, 2010Date of Patent: October 7, 2014Assignee: Citrix Systems, Inc.Inventors: Prabakar Sundarrajan, Junxiao He, Sergey Verzunov, Charu Venkatraman, Anil Shetty

Patent number: 8848710Abstract: The present invention is directed towards a method and system for providing a technique referred to as flash caching to respond to requests for an object, such as a dynamically generated object, from multiple clients. This technique of the present invention uses a dynamically generated object stored in a buffer for transmission to a client, for example in response to a request from the client, to also respond to additional requests for the dynamically generated object from other clients while the object is stored in the buffer. Using this technique, the present invention is able to increase cache hit rates for extremely fast changing dynamically generated objects that may not otherwise be cacheable.Type: GrantFiled: July 25, 2012Date of Patent: September 30, 2014Assignee: Citrix Systems, Inc.Inventors: Prabakar Sundarrajan, Prakash Khemani, Kailash Kailash, Ajay Soni, Rajiv Sinha, Saravana Annamalaisami, Bharat Bhushan K.R., Anil Kumar

Patent number: 8788581Abstract: A method for maintaining a cache of dynamically generated objects. The method includes storing in the cache dynamically generated objects previously served from an originating server to a client. A communication between the client and server is intercepted by the cache. The cache parses the communication to identify an object determinant and to determine whether the object determinant indicates whether a change has occurred or will occur in an object at the originating server. The cache marks the object stored in the cache as invalid if the object determinant so indicates. If the object has been marked as invalid, the cache retrieves the object from the originating server.Type: GrantFiled: January 18, 2013Date of Patent: July 22, 2014Assignee: Citrix Systems, Inc.Inventors: Prabakar Sundarrajan, Prakash Khemani, Kailash Kailash, Ajay Soni, Rajiv Sinha, Saravana Annamalaisami, Bharath Bhushan K.

Patent number: 8739274Abstract: A device that implements a method for performing integrated caching in a data communication network. The device is configured to receive a packet from a client over the data communication network, wherein the packet includes a request for an object. At the operating system/kernel level of the device, one or more of decryption processing of the packet, authentication and/or authorization of the client, and decompression of the request occurs prior to and integrated with caching operations. The caching operations include determining if the object resides within a cache, serving the request from the cache in response to a determination that the object is stored within the cache, and sending the request to a server in response to a determination that the object is not stored within the cache.Type: GrantFiled: June 29, 2005Date of Patent: May 27, 2014Assignee: Citrix Systems, Inc.Inventors: Prakash Khemani, Prabakar Sundarrajan, Lakshmi Kumar, Kailash Kailash, Ajay Soni, Rajiv Sinha, Saravanakumar Annamalaisami

Patent number: 8726006Abstract: A system and method for establishing a virtual private network (VPN) between a client and a private data communication network. An encrypted data communication session, such as a Secure Sockets Layer (SSL) data communication session, is established between a gateway and the client over a public data communication network. The gateway then sends a programming component to the client for automatic installation and execution thereon. The programming component operates to intercept communications from client applications destined for resources on the private data communication network and to send the intercepted communications to the gateway via the encrypted data communication session instead of to the resources on the private data communication network.Type: GrantFiled: August 21, 2012Date of Patent: May 13, 2014Assignee: Citrix Systems, Inc.Inventors: Prabakar Sundarrajan, Junxiao He, Ajay Soni, Shashidhara Nanjundaswamy, Arkesh Kumar

Patent number: 8706877Abstract: 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.Type: GrantFiled: December 30, 2005Date of Patent: April 22, 2014Assignee: Citrix Systems, Inc.Inventors: Prabakar Sundarrajan, Junxiao He, Sergey Verzunov, Charu Venkatraman, Anil Shetty, Josephine Suganthi

Patent number: 8499057Abstract: The present invention is directed towards a “flash crowd” technique for handling situations where the cache receives additional requests, e.g., nearly simultaneous requests, for the same object during the time the server is processing and returning the response object for a first requestor. Once all such nearly simultaneous requests are responded to by the cache, the object is flushed from the cache, with no additional expiry time or invalidation action needed. This technique of the present invention enables data to be cached and served for very small amounts of time for objects that would otherwise be considered non-cacheable. As such, this technique yields a significant improvement in applications that serve fast changing data to a large volume of concurrent users, such, for example, as real time stock quotes, or a fast evolving news story.Type: GrantFiled: February 22, 2011Date of Patent: July 30, 2013Assignee: Citrix Systems, IncInventors: Prabakar Sundarrajan, Prakash Khemani, Kailash Kailash, Ajay Soni, Rajiv Sinha, Saravana Annamalaisami, Bharath Bushan K.
