摘要： The present invention is directed to a system for multiplexing data transmissions exchanged between a host computer system and a user workstation connected by a communications link. One or more host application programs reside upon and are executed by the host computer system while a terminal emulation program having the capability of simultaneously displaying one or more host application program screens resides upon and is executed by the user workstation. The data transmission multiplexing system comprises a session manager program residing upon and executed by the host computer system for establishing one or more program sessions with the host application programs, each of the program sessions generating its own individual datastreams, and a single program session with the terminal emulation program utilizing a single connection between the host computer system and the user workstation. The terminal emulation program simultaneously displays the host application program screen for each of the program sessions established between the session manager program and the host application programs. The multiplexing system includes a multiplexing program for performing the following functions: (1) building inner data packets from the individual datastreams generated by each program session; (2) inserting the inner data packets into one or more data transmission packets for transmission between the host computer system and the user workstation over the single logical connection; and (3) removing the inner data packets from the one or more data transmission packets for recreating the individual datastreams therefrom.

摘要： A system for measuring inter-nodal transmission delays in a communications network interconnecting a source node, a destination node and a plurality of intermediate nodes requests a response from the destination node, receives a response from the destination node and then determines both an issue time at which the request is issued by the source node and a receipt time at which the response is received by the source node. A transmission delay between the source node and the destination node is deterined by calculating a difference between the issue time and the receipt time.

摘要： A system and method for optimizing the utilization of a cache memory in an input/output controller in a computer system which also includes a central processing unit and a plurality of direct access storage devices. The optimizing system calculates a demotion time where the demotion time is an approximation of the length of time that a track of data will reside in the cache memory in the input/output controller after its last input/output request from the central processing unit. The optimizing system further intercepts an input/output request from the central processing unit for a requested track of data, determines an elapsed time between successive input/output requests from the central processing unit for the requested track of data, determines whether the elapsed time is greater than the demotion time and optimizes the requested track of data by inhibiting the requested track of data from being loaded into the cache memory if the elapsed time is greater than the demotion time.

摘要： A pattern based space management apparatus and method for a computer system having at least two levels of hierarchical storage is comprised of computer code for creating and maintaining a data base containing size information and historical information about the use of data sets residing on the computer system. Code is provided for calculating a next reference date for certain of the data sets and a confidence level for each of the next reference dates from information in the data base. An input device may be used to define an amount of the highest level storage space which is to remain available. Code is provided for identifying which data sets should be migrated between the storage levels of the computer system based on the next reference dates, the confidence levels, the sizes of the data sets, and the amount of highest level storage space which is to remain available. Code is also provided to effect the migration of the data sets identified for migration.

摘要： The present invention is directed to a system and method for the distributed management of the storage space and data on a networked computer system wherein the networked computer system includes at least two storage devices for storing data files comprised of one or more binary objects. The distributed storage management system includes a device for selectively copying the binary objects stored on one of the storage devices to another of the storage devices and another device for calculating a current value for a binary object identifier for selected binary objects stored on the storage devices wherein the calculation of the binary object identifier is based upon the actual data contents of the associated binary object. The distributed storage management system further includes a device for storing the current value of the binary object identifier as a previous value of the binary object identifier, another device for comparing the current value of the binary object identifier associated with a particular binary object to one or more previous values of the binary object identifier associated with that particular binary object and a device for commanding the device for selectively copying binary objects in response to the device for comparing.
