The present invention relates to a system for (1) protecting the transmission of packet streams between a host computer and one or more client computers, and (2) upon reception, (a) reconstructing any outage damage caused during the transmission to the packet streams, and (b) digitally recording the reconstructed packet streams to a file. The present invention also relates to a method for dynamically generating a file index table as the packet stream is being digitally recorded.

System for protecting the transmission of live data streams, and upon reception, for reconstructing the live data streams and recording them into files

Applications, systems and methods for permitting simultaneous use of a file by two or more computers over a network may include storing the file locally in a local storage device associated with a local computer; providing access to the file by at least one remote computer which is connectable to the local computer via the network, and wherein at least one of the computers is connectable to the network through a firewall element. The file may be stored in at least one remote storage device associated with the at least one remote computer, respectively, and versions of the file contained on the one or more remote storage devices are synchronized with that on the local device by transmitting over the network connecting the one or more remote storage devices with the local device, at least one of Delta files and Inverse Delta files between the remote storage devices and the local storage device. A method of remotely observing computer activity on a second computer remote with respect to a first computer is also provided. Further, file sharing systems and methods are provided for sharing files among computers.

An information service provider network includes a content gateway to process requests for information from a client terminal. The content gateway includes a router for receiving a request for information from the client terminal. The request includes a domain name and additional content. The router forwards the request according to the domain name to a selected one of a plurality of processors to further process the request. The selected one of the plurality of processors identifies an information source to satisfy the request in response to the additional content of the request.

System and method for processing a request for information in a network

Several ways of identifying users and collecting demographic information and market information are disclosed, including branding a browser with a unique identification in each user request, identifying a user by his key strokes or mouse clicks, gathering demographic information using multiple data sets and by monitoring network traffic. Additionally, user requested content is distinguished from other, non-user content, and the performance of a server can be monitor and analyzed from a client a client perspective. Further, an Internet user's Internet data is routed to a known domain on the Internet, from which it is routed on to the intended recipient. The domain includes proxy servers which proxy the user's data requests to the domain, and database servers, which filter and build a database of the user's Internet usage. Particular data concerning certain behaviors of interest, such as purchasing data, is filtered into the database, and can form the basis for numerous market measures.

In the face of unacceptable data loss on connections between a content source and a content consumer, additional connections therebetween are opened. These additional connections are preferably opened between the content source and a proxy disposed between the content source and the content consumer. The proxy may then seam together data streams received from the content source across the additional connections before passing a resultant seamed stream to the content consumer. The seamed stream may be constructed by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source. This derivation may be made on the basis of identifying characteristics (e.g., packet sequence numbers and/or time stamps) common throughout each of the data streams received from the content source.

Method and apparatus for seaming of streaming content

Requests are identified as being for a cacheable object or a non-cacheable object according to information included in a Uniform Resource Locator (URL) associated with the object. For example, the URL may include a port designation for requests for cacheable objects (e.g., images and the like). Thus, a request may be recognized as being for a cacheable or non-cacheable object according to the port on which the request is made. In some cases, requests for non-cacheable objects may be made on port 80. A router may be thus configured to recognize a request as being for a cacheable object or a non-cacheable object according to a port on which the request is received and redirect it to a cache as appropriate.

Scheme for segregating cacheable and non-cacheable by port designation

In the face of data loss on connections between a content source and a content consumer, additional connections therebetween are opened These additional connections are preferably opened between the content source and a proxy disposed between the content source and the content consumer The proxy may then seam together data streams received from the content source across the additional connections in a recording on a computer-readable medium The seamed stream may be constructed by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source This derivation may be made on the basis of identifying characteristics (eg, packet contents) of packets from each of the data streams received from the content source

Method for real time protocol media recording

Multiple content consumers are serviced from a single content source on the basis of an examination of a description of the content requested by the content consumers. That is, a proxy communicatively coupled to the content consumers is configured to examine the requests for content made by the consumers and to determine (e.g., on the basis of meta information associated with the content and/or the content requests, whether live or prerecorded streaming content has been requested. If live content has been requested, the proxy is further configured to dynamically reflect (in a protocol independent fashion) any existing streams that include such content to those of the content consumers that are requesting such content. If prerecorded content is being requested, the proxy is configured to play back a stored version thereof, if available, or to open a connection to the content source for such playback if no stored version of the content is available. In some cases, playbacks of live or stored content from the content source may involve data seaming of multiple connections between the proxy and the content source.

Method and apparatus for dynamic proxy reflecting of streaming content

A burst of information included in a data stream received from a content source across one or more computer networks (e.g., according to RTP) is smoothed at a proxy disposed between the content source and one or more content consumers so as to provide one or more output data streams to the one or more content consumers that reproduce the information included in the burst over a time interval longer than that in which it was received at the proxy. The proxy may be disposed at the last media link between the content source and at least one of the content consumers.
