Abstract: A method and apparatus for filtering messages comprising determining a first semantic anchor corresponding to a first group of messages, for example, legitimate messages and a second semantic anchor corresponding to a second group of messages, for example, unsolicited messages. Determining a vector corresponding to an incoming message; comparing the vector corresponding to the incoming message with at least one of the first semantic anchor and the second semantic anchor to obtain a first comparison value and a second comparison value; and filtering the incoming message based on the first comparison value and the second comparison value.

Abstract: A method of automatically queuing calls for later transmission in connection-oriented networks instead of blocking them when network resources are unavailable at the time the request is received, as currently done. A simple call queuing method holds up call setup messages at each switch along an end-to-end path of a network until resources become available. This simple, known queuing method suffers from poor network utilization and long call queuing delays. However, if calls that can be queued have known holding times, a call scheduling method that results in reduced call queuing delays and improved network utilization according to the present invention can be realized.

Abstract: Techniques are provided for combining searching and browsing into a single interface. The topology and content of a document collection or web site is determined and user information need keywords are determined. Relevant documents are identified using search techniques and the relevant document paths determined. The relevant document paths are analyzed using information scent to generate information scent values for the relevant document paths. A display attribute of the associated connection or link is then synthesized based on the information scent, the keywords and the document. The process repeats for each new document or web page.

Abstract: A program-changing method for a network having at least two nodes that include a first and a second predetermined node, each network node having a program, includes a network management system connected to the first predetermined node of the network. New changing program data and a control signal are transmitted to the first predetermined node connected to the network management system which is disposed in the network separately from the nodes and configured to manage the changing of the programs in the nodes. The first predetermined node replaces its program with the new changing program data. The network management system transmits a program-transmitting-signal to the first predetermined node, causing the transmission of the newly changed program data stored therein to the next predetermined node to change the program of the next predetermined node under control of a respective control signal to the second predetermined node from the network management system.

Abstract: A method and system for communicating to a sender an availability of receiving a new message includes providing buffers having at least one corresponding slot for storing a message and providing a credit signal that communicates to the sender only when all of the buffers have at least one of the corresponding slot available for storing a new message. Each of the buffers is monitored for whether at least one of the corresponding slots is available for storing the new message. A corresponding receiver counter is provided for each of the buffers. Each receiver counter is decremented when all of the buffers have at least one corresponding slot available for storing the new message. Each of the buffers is configured to receive a corresponding particular message type. The particular message type of the new message is determined. The new message is loaded into the corresponding slot of one of the buffers which is configured for receiving the particular message type of the new message.

Abstract: A method for providing electronic mail return receipts with video of the electronic mail recipient is disclosed. The electronic mail recipient opens an electronic mail message which initiates recording of the electronic mail recipient. The recording may be terminated when the recipient closes the electronic mail or minimizes the electronic mail message window. Recording may also end after a predetermined amount of time after the electronic mail message is opened.

Abstract: In a wireless internet access system, an access point of a base station and a group of wireless modems communicate over a wireless channel. This wireless channel comprises a sequence of “dwells,” where each dwell represents a period of time, e.g., 20 milli-seconds (ms). Each dwell can convey both uplink (or upstream) and downlink (or downstream) transmissions to, and from, the group of wireless modems. However, in each dwell a particular wireless modem can only communicate half-duplex—either provide an uplink transmission to the access point, or receive a downlink transmission from the access point. The access point load balances, or distributes, the downlink transmissions to the group of wireless modems across the dwells upon detection that some dwells convey more downlink transmissions than other dwells.

Abstract: A system for verifying modem status for a telecommunications service provider in a broadband network serviced by a central office. The system comprising an internet interface for receiving a modem status request from the telecommunications service provider via a telecommunications network and an integrator capable of retrieving subscriber information and a server connected to the internet interface for receiving the modem status request and transmitting the modem status request to the integrator. The integrator interprets the modem status request and retrieves corresponding subscriber information and transmits the corresponding subscriber information to the server, the server thereby converting the corresponding subscriber information to a central office request and sending the central office request to the central office.

Abstract: A method directed to a dynamic proxy reconfiguration which is implemented in plural network servers. The invention is directed to a computer-executable program for use in proxy network servers which enables each proxy server to dynamically sell its unused capacity to other web sites for specific periods of time. The invention has particular utility in connection with World Wide Web servers, but can be used with other servers where proxy servers may be present.

Abstract: In a data communication network operated under the TCP/IP suite of protocols the invention adds an adaptive streaming (AS) layer, inserted between the IP and the TCP protocol layers, in which the received data packets of each open TCP connection are temporarily queued and from where they are first reordered then, delivered to the TCP layer at a pace matching the optimal receiving rate of TCP connections. Thus, the invention adds a rate-based transmission mechanism to the TCP layer for the received data packets so as to better adapt to higher-speed communication lines and to reduce drastically the burstiness of the TCP flow control.

Abstract: A transmission circuit for transmitting data of varying priorities on a network medium is provided. The transmission circuit includes sub-circuits to receive and store data frames into random access memory frame buffers and priority tables. Sub-circuit priority resolution selects the highest priority frame, and sub-circuit frame transmission transmits the frame to a media access controller to be made available by the network medium.
