A method for managing network resources is also disclosed.
Abstract:
An integrated messaging system uses existing messaging systems to receive, store, retrieve and manage messages in media types and formats appropriate to each existing system using protocols which are specific to that system. Two or more systems are tightly coupled in that a message received in one system can be accessed from all other systems. Coordination between messaging systems is achieved by a synchronizer system running in one of the existing servers or in a stand-alone server. The synchronizer comprises a plurality of threads which sequentially examine corresponding mailboxes in each messaging system and update the message states in each system so that all message states correspond. In order to determine whether a message state has changed, the synchronizer maintains a state database which stores the state of each message in all messaging systems which are connected to the synchronizer. A further gatway thread is provided so that messages can be sent directly from one messaging system to another messaging system. The synchronizer is connected to each messaging system via a standard CMC interface so that it can log onto each messaging system as a trusted server and modify user's mailboxes without requiring a password.
Abstract:
An improved messaging system (100, 900) enables a message recipient to take notes electronically while retrieving messages, such as by electronically extracting and separately recording a portion of a received message in a scratchpad area (250, 1050) of his or her mailbox (111, 911) or by dictating into a telephone (102, 103), typing on a terminal (902, 903) keyboard, or entering on a Touch-Tone telephones' keypad, words and/or numbers, into the scratchpad area, for subsequent use by the message recipient. The messaging system then enables the message recipient either to retrieve the electronic notes from the scratchpad area, or to automatically place a call to a telephone number that is contained in the electronic notes in the scratchpad area. An improved graphical user interface (915) provides the message recipient with easy access to, and control over, this functionality of the messaging system.
Abstract:
A method of providing a document to a client coupled to a server is provided. The server provides a number of Internet services to the client, including functioning as a caching proxy on behalf of the client for purposes of accessing the World Wide Web. The proxying server includes a persistent document database, which stores various attributes of all documents previously retrieved in response to a request from a client. When a Web document is retrieved from a remote server in response to a request from the client, the database is consulted and the stored information relating to the requested document is used by the server in transcoding the document. The document is transcoded for various purposes, including to circumvent bugs or quirks found in the document, to size the document for display on a television set, to improve transmission efficiency of the document, and to reduce latency. The transcoder makes use of the document database to perform these functions. The document database is also used for prefetching previously requested documents and images and for reducing latency when downloading images to the client.
Abstract:
The disclosure of the current invention describes a method of handling a message or a document to be released external of a secure computer environment. The message or the document is first directed to a trusted sealing device which displays the message or the document to a human user for visual checking. If the message or document is acceptable to the human user, the method associates the message or the document with a seal produced by the trusted sealing device. The message or the document is then directed along with the associated seal to a gateway which deletes portions of the header and checks the validity of the associated seal. If, as a result of this verification, it is determined that the associated seal is validly associated with the message or the document, the method attaches predetermined header portions to the message or document and communicates the message or the document from the secure computer environment.
Abstract:
A user interface provides a uniform control scheme among different devices in a personal communications routing system. The system allows devices such as a personal computer, personal information communicator, pager, fax machine and base station to be operated with a standard twelve key telephone keypad controller for the purpose of accessing electronic messages such as e-mail, voice-mail, fax transmissions, etc. Handheld communicators are docked with the devices to provide wireless transmission between a base station and numerous devices in a multi-user environment. The base station receives electronic messages for the users in, e.g., an office and routes the messages to a device as the user instructs. The user is able to perform operations on the messages such as reading, responding, deleting, etc., by using the keypad. A visual indication of user designated message bins, along with icons to represent messages received, is used to special advantage by coordinating the bin layout with the arrangement of keys on the keypad. Another feature of the system is that rules can be predefined to route, screen or otherwise manipulate the messages. The rules are applied by the base station to each incoming message. Different users can have different rules such as automatic forwarding of messages, automatic paging upon receipt of a message and sorting of messages by sender's name or time of day.
Abstract:
Transmitting e-mail over a network. According to a preferred embodiment, a current node in the network receives an e-mail message to be distributed to at least one recipient. The e-mail message comprises an attachment reference comprising the network address of an attachment stored locally to a previous node of the network. The costs of forwarding the e-mail message given a previous network location of the attachment is compared to the costs of moving the attachment locally to the current node. A copy of the attachment is retrieved, stored locally to the current node, and the attachment reference is updated, in accordance with the comparison.
Abstract:
A method is disclosed for publishing a hypertext file set on a world-wide web server machine by packaging the hypertext file set as an e-mail message on a client machine, transporting the e-mail message over the internet from the client machine to the world-wide web server machine, unpacking the e-mail message to recover the hypertext file set, and depositing the hypertext file set into a memory means on the world-wide web server machine. By using the e-mail transport mechanism, a direct internet connection between the client and server is not necessary. Consequently, the method allows files to pass through security firewalls and allows geographically disperse individuals to remotely update information at a WWW site without compromising server security. In addition, processing time is not wasted during direct connections sharing the server's resources and internet bandwidth is not wasted. Finally, because this method uses standard internet protocols and generic server software, the WWW server is not cluttered with client-specific software to handle special protocols and data structures.
Abstract:
A method for a sender to automatically distribute information to a receiver on a network using devices (such as printers and facsimile machines) and communication channels (such as electronic mail) defined in a receiver profile. The receiver profile establishes the properties and mode for receipt of information for receivers on the network and the profile is published in a network repository for all network users or is accessible by selected groups or individuals on the network. Receivers have additional control over network senders by defining an information filter which further controls sender channel access (to a receiver) by defining some channels as having priority of access such as direct or delayed access, as well as selectively permitting senders to override the receiver profile. Consequently, receiver profiles provide a variable receiver definable link to senders using multiple forms of media as well as multiple hardware platforms and network configurations.
Abstract:
A multimedia collaboration system that integrates separate real-time and asynchronous networks--the former for real-time audio and video, and the latter for control signals and textual, graphical and other data--in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations and their interconnecting LANs and WANs. In a particular preferred embodiment, a plurality of geographically dispersed multimedia LANs are interconnected by a WAN. The demands made on the WAN are significantly reduced by employing multi-hopping techniques, including dynamically avoiding the unnecessary decompression of data at intermediate hops, and exploiting video mosaicing, cut-and-paste and audio mixing technologies so that significantly fewer wide area transmission paths are required while maintaining the high quality of the transmitted audio/video.
