Abstract: A method to obtain a cache miss ratio curve where a memory blocks of a cache have variable block sizes. By stacking sets of counters, each set being for a different block size, a stack distance for variable block sizes can be obtained and used to determine a miss ratio curve. Such curve can then be used to select a cache size that is appropriate for an application without requiring excessive memory. Methods can be used for batches of request, can apply limits to block sizes, and rounding for intermediary block sizes, they can be used with pruning, and their space complexity can be held constant.

Abstract: For a given application, increasing the size of a cache is beneficial up to a certain point and the number of hits does not increase significantly with a greater cache size. This disclosure provides a method to determine a miss ratio curve, for a cache having data blocks with a time-to-live. A hashed value of a data block's key address can be used to generate a 2D HLL counter for storing expiry times of the data blocks. The 2D HLL counter can be converted to a 1D array, from which a stack distance can be calculated. A frequency distribution of stack distances can then be converted into a miss ratio curve, from which an appropriate cache size can be selected.

Abstract: The method generates and displays an adaptive graphical user interface of a current configuration and current capabilities of a networked peripheral device connected to a local area network. The method includes the steps of requesting from a user's work station a current configuration and current capabilities of a networked peripheral device, transmitting, in response to the request, an interrogation command to the networked peripheral device over the local area network, and receiving, from the networked peripheral device, information corresponding to a current configuration and capabilities of the networked peripheral device.

Abstract: A protocol independent method of transmitting a data packet from a first application program executing on a first device which is interfaced to a LAN to a second application program executing on a second device which is interfaced to the LAN. A protocol independent interface (PII) program is initialized which determines which protocols are available for use, assigns an access line to each protocol that is available for use, assigns an access ID to the first application program, and creates mapping information that indicates a one-to-one correspondence between an access ID/access line pair and a block of protocol specific information which includes a protocol header having predetermined address data. A data packet is sent to the PII program together with the access ID of the first application program and a destination ID for the second application program, and one of the available protocols is selected to transmit the data packet.

Abstract: A novel molding composition is described which prevents plateout of pigment on the surface of a mold or shaping apparatus during the molding or shaping operation. The composition has improved thermal and oxidation stability as well as increased compatibility of the components of the composition. The composition comprises a thermoplastic resin, a fluorescent pigment, a metal salt or complex, polymer or oligomer reagent containing a reactive functionality and other conventional additives. The composition is useful in preparing such molded articles as films, bottles, closures, furniture and toys.
