Abstract:

The present invention is particularly applicable to navigation of Internet by two-way interactive communication mobile devices that are capable of wireless communication via a link server with service providers or network servers on the Internet. Despite the limited computing resources in mobile devices that make it economically and technically impractical for the mobile devices to operate a local browser functioning as if it was in a desktop computer, the present invention allows the mobile devices to interact effectively with the Internet using a control engine operating in the link server and an interface engine operating in the mobile devices. The control engine, which utilizes the computing resources of the link server device, is responsible for tasks that require considerable computing power and memory, such as processing of URL requests, interpretation of markup language files, management of data cache and variable states. Further, working with a message processor in the server device, the control engine communicates with an interface engine using a compact data format that is efficiently transportable in the wireless data network. The interface engine typically performs tasks that do not require considerable computing power and memory, such as receiving input data from users, and the rendering of the compact data format received from the link server device, to cause the mobile device to display contents in the markup language files on a display screen.

Abstract:

A credential caching proxy server that handles credential caching for a set of wireless client devices is disclosed. The credential caching proxy server handles most credential transactions for wireless client devices that wish to access resources within a protected realm where the protected realm requires credentials. In one embodiment, the credential caching proxy server intercepts and caches a wireless clients credentials when a credential is first sent from the wireless user agent to a protected server. The cached credential will then be used for all requests to resources within the same protected realm. Thus, after first sending a first credential for accessing the resource in a particular realm, the wireless user agent does not need to attach the credential for all the subsequent requests for any other resources belong to the same realm. In an alternate embodiment, the proxy server sends a special request to the wireless client device requesting a credential for a particular resource. The special request may take the form of a simple preformatted display page such that a âdumb terminalâ wireless client device can be used to communicate with protected Internet resources even though the âdumbâ wireless client device has no concept of authentication and authorization.

The invention allows access to the Internet by two-way mobile communication devices capable of wireless communication via a link server. Despite limited computing resources in the mobile devices, the invention allows the mobile devices to interact with Internet entities using a control engine in the link server and an interface engine in the mobile devices. The control engine utilizes the computing resources of the link server and handles tasks requiring considerable computing resources, such as processing of URL requests, interpreting markup language files, managing a data cache and variable states.

Abstract:

A system and a method for implementing a virtual data center. In which, the functions to be performed by a computer, and the access the computer equipment is required to have to the storage and network facilities, are decoupled from the hardware, and instantiated dynamically on any suitable computer equipment, without any manual intervention. In a virtual data center, all the physical resources are virtualized and arranged dynamically, to meet the functional requirements of the data center.
