Abstract: A reservation based bandwidth management system for a data processing system network allocates network resources to client computer systems requesting access to other computer systems within the network based on a bandwidth predicting algorithm. The bandwidth predicting algorithm utilizes an autoregressive integrated moving average trend analysis to forecast future values of bandwidth capacity at a link or system level used by elements that do not conform to a reservation policy. The bandwidth predictor may utilize a utility that analyzes the bandwidth utilization trend over a previous period of time and generates appropriate seasonal coefficients to be used by the predictor algorithm.

Abstract: Communications network performance is tested utilizing a test scenario simulating actual communications traffic on the network to be tested. A console node is provided on the network for establishing the test scenario and assigning the test scenario to endpoint nodes on the network to be tested. Each endpoint node is assigned an endpoint node specific test protocol. Execution of the test protocols by the endpoint nodes is initiated by the console node. Performance data such as throughput, transaction rate and response time may be monitored at selected ones of the endpoint nodes and reported to the console node either as it is generated or after completion of the test. The test scenario may be terminated when all endpoint node specific test protocols have completed execution or when any one endpoint completes execution of its test protocol. Multiple network protocols may be utilized within a single test scenario.

The computer system includes a plurality of ports which are connected to a number of diverse types of communications media. At least one of the ports comprises a network port controlled by a network socket driver, so that the communications driver can be used in connection with lower-level networking drivers which may be provided by a variety of manufacturers. The communications driver selectively establishes a communications session such that the computer system will operate as a terminal with the remote device over one of the communications media, as selected by an operator. The communications driver initially enables the operator to identify a communications medium and a remote device, and the driver thereafter selects one of the ports in response to identification by the operator of a communications medium and a remote device.

Abstract: Computer users may utilize different web browsers to access a server system on the World Wide Web (WWW) to create or join a collaborative browsing session. The users or collaborators in a session are connected by one or more controllers in the server system. When a collaborator creates or joins a session, mobile code is transmitted from the system to the collaborator's computer to create a surrogate thereon, which monitors the collaborator's interaction with a web browser on the computer. The controllers communicate with all the surrogates of the collaborators to coordinate the collaborative browsing effort. When one of the surrogates detects a change by a collaborator of a uniform resource locator (URL), the new URL is communicated through the controllers to the surrogates of all other collaborators in the session. As such, the collaborators are able to move from one URL to another to browse information in a synchronous manner.

Abstract: A multiport polling system for a network switch including a plurality of network ports, each including receive and transmit buffers. Each port includes port status logic for providing status signals indicative of whether a corresponding port has received data from a network device and whether a corresponding port has available space to receive data to transmit to a network device. The network switch further includes a switch manager for controlling data flow between the ports. The switch manager includes polling logic for periodically polling the port status logic of each port for receiving the status signals, and a memory for storing values indicative of the status signals for each port. In this manner, all of the ports are simultaneously polled in a singe query and the receive and transmit status of each port is maintained in the memory.

Abstract: A method of identifying computer screens is disclosed. The method is particularly useful in identifying IBM host screens in script creation and playback. According to the method, a signature is composed for a given screen. The signature comprises characteristics of a given screen which differentiate that screen from substantially different screen displays. For an IBM host screen, signature composition is based upon the screens protected fields. The protected fields are further processed by removing transient information such as the date and time.

Abstract: According to the present invention, when image data high-efficiency-coded based on the MPEG standard or the like is clustered at every sector of a predetermined number, a link sector is provided at a connected portion of each cluster and the image data is interleaved and recorded on a mini disc, the image data is recorded on each cluster at the unit of 1GOP. When the mini disc is a preformatted one and a P picture or B picture exists at the starting portion of the cluster, a picture which becomes a predictive standard is encoded as an I picture and recorded on the link sector of the immediately-preceding cluster independently of an original P picture. Upon decoding, when the I picture was not recorded on the link sector of the immediately-preceding cluster, the P picture or the B picture recorded at the starting portion of the cluster is inhibited from substantially being decoded.

Abstract: Natural numbers are assigned to represent DNA and mRNA nucleotide bases (n-numbers 0, 1, 2, 3), base pairing numbers in RNA (p-numbers 0, 1, 2, 3), and amino acids in protein (z-numbers with seventeen prime numbers and odd numbers 1, 25, 45; all smaller than 64). These numbers reflect intrinsic properties of the nucleotide bases, their triplet-base codon combinatorics and chemical bonding properties (hydrogen bonds, hydrophobicity, codon positions, and molecular sizes). Gene and protein sequences may be represented, characterized and interpreted by their specific n-sums and z-sums. Base dimers/oligomers and dipeptides/oligopeptides are found to correspond to their sums, as verified by using statistical and other methods. Utility rules are devised for applications in base dimers distribution, RNA base pairing, oligomer repeats and the encoded oligopeptide repeats. Conserved base pairs in four stems of a given mitochondrial tRNA correlate well with the z-number in the encoded hydrophobic amino acid.
