Abstract: A method, article of manufacture, and apparatus for ordering and retrieving pages of data in a computer operating system is provided. The invention provides for ordering pages of data in a computer operating system during execution of a program file according the order in which the pages are accessed. In one embodiment, a time-ordered access sequence of a plurality of uncompressed pages of data is traced. The plurality of uncompressed pages of data is then compressed into one or more blocks of compressed pages and correlated with the one or more blocks of compressed pages in a relocation directory. The one or more blocks of compressed pages can then be stored according to the time-ordered access sequence.

Abstract: A method and apparatus are provided for displaying image and facsimile data on a host-based application display. A host computer generates control and download command data for displaying the image or facsimile data. The image and facsimile data is processed by a non-programmable-terminal (NPT) or a programmable work station (PWS) for presentation of a display screen. When a user requests another function, the NPT or PWS stores image information and sends image information to the host computer. The save image information includes cache image counter data, scaling and viewed image screen location data that is used to restore the displayed image and facsimile data when the user returns to the previous function. Both the user and host application can specify a foreground color and a background color for the image and facsimile data display.

Abstract: A method and apparatus are provided for detecting and controlling data stream splicing in a stream of multimedia digital data over a distribution communications network. Sequential transport stream packets are obtained. Predetermined fields of each transport stream packet are interrogated to identify a splice in the data stream. A predetermined task is initiated responsive to an identified splice. In accordance with feature of the invention, one predetermined task initiated responsive to the identified splice includes masking the interrogated predetermined fields to mask the splice in the data stream.

Abstract: Provided are a method and system for replacing terminals, linked in a client server relationship with a central server, interacting with hardware specific programs within the central server, and wherein each terminal is identified by hardware specific programs within said central server via specific hardware attributes, and where the specific hardware attributes include at least a port identification and an I/O processor identification associated with the port identification. The method and system achieve the foregoing via the following. A processor is substituted for a selected terminal. Particular hardware attributes of the selected terminal are identified. The identified particular hardware attributes of the selected terminal are emulated using communications software.

Abstract: An improved method and apparatus are provided for queuing and triggering the flow of data across ATM networks. A connection is established between an insertion server and a client multiplexer. The insertion server prepares a timing response and establishes a transmit queue threshold for a pending trigger point for inserting data. The insertion server enqueues data. Responsive to receiving a timing request from the client multiplexer, the insertion server sends the timing response. Responsive to receiving a stream request from the client multiplexer, the insertion server transfers the enqueued data. The client multiplexer includes a timer for identifying an offset time between sending the timing request and receiving a timing response from the insertion server. The client multiplexer uses the offset time to set a count down timer for sending the stream request. The client multiplexer processes the data transferred by the insertion server and optionally sends a stop stream command to the insertion server.

Abstract: An improved method and apparatus are provided for producing transmission control protocol (TCP) checksums using internet protocol (IP) fragmentation. A transmission control protocol module receives packet data to be transmitted and prepares a first internet protocol data fragment without a checksum for the received packet data. The first internet protocol data fragment is transmitted. Collecting checksum is performed during the transmission of the first internet protocol data fragment. Then an internet protocol header fragment including the collected checksum is transmitted.

Abstract: A method and apparatus are provided for generation of predicted responses in a computer communications network system. A server in the computer communications network system predicts the client's next request based on the present client's request. The server sets a trigger that recognizes a match of the client's predicted request. When a client's predicted request arrives, the trigger sends the response. Additionally, the server associates a timeout action with the predicted response so that if a predicted request is not received within the timeout interval or other events occur before the predicted request arrives, the triggered response is removed and an alternative action is performed.
