Abstract: A method for benchmarking and optimizing the end-to-end processing performance of a computer network system that identifies performance variables that affect system performance, runs an initial performance test to establish a baseline value for each performance variable and a baseline performance value for the system, pins all performance variables to their constant baseline values except for one floating variable, incrementally changes the value of the floating variable, conducts a new performance test for each changed value, records the values of the system performance and the associated performance variables in a matrix, restores the floating variable to its baseline value, and repeats the prior steps for a new floating variable. The method proceeds until all performance variables have been tested as the floating variable and the matrix is complete.

Abstract: A system and method for Near Video On Demand (NVOD) transmission of a program from a server to a plurality of clients. The program is partitioned into segments. Each segment is transmitted repeatedly, with the transmission rate of segments subsequent to the first segment being lower than the transmission rate of the first segment. The transmission of the segments is scheduled in a manner that minimizes the aggregate transmission bandwidth, subject to constraints related to client parameters such as client storage capacity and client recording rates. Preferably, the sequences are partitioned further into subsequences, and redundant subsequences are used for error correction. Preferably, the segments, or the subsegments, include metadata such as segment or subsegment length, segment or subsegment sequence number, or the time until the next transmission of the sequence or subsequence.

Abstract: A method for initiating a tunneling association in a data network. The method includes negotiating private addresses, such as private Internet Protocol addresses, for the ends of the tunneling association. The negotiation is performed on a public network, such as the Internet, through a trusted-third-party without revealing the private addresses. The method provides for hiding the identity of the originating and terminating ends of the tunneling association from the other users of the public network. Hiding the identities may prevent interception of media flow between the ends of the tunneling association or eavesdropping on Voice-over-Internet-Protocol calls. The method increases the security of communication on the data network without imposing a computational burden on the devices in the data network.

Abstract: A method for enabling users to exchange group electronic mail by establishing individual profiles and criteria, for determining personalized subsets within a group. Users establish subscriptions to an electronic mailing list by specifying user profile data and acceptance criteria data to screen other users. When a user subscribes, a web server establishes and stores an individualized recipient list including each matching subscriber and their degree of one-way or mutual match with the user. When the user then sends a message to the mailing list, an email server retrieves 100% her matches and then optionally filters her recipient list down to a message distribution list using each recipient's message criteria. The message is then distributed to matching users. Additionally, email archives and information contributions from users are stored in a database. A web server creates an individualized set of web pages for a user from the database, containing contributions only from users in his recipient list.

Abstract: The technology of the present invention allows the creation of a single master document, called a script, to serve multiple functions by defining a set of data fields as well as a hierarchy of organization in terms of token-value pairs. By applying a “distillation” process the content of the script may be optimized, effectively compressing the script for various purposes such as user interface generation, data processing, or data transmission. The size of a set of data records, for example, may be greatly reduced by separating the content of the data from the meaning, permitting a computer with limited resources such as a hand-held unit to transmit a very large amount of data in a small data record along with a “meaning token”. The distilled data package may then be expanded by the receiving unit using the “meaning token” in the package, which contains the instructions for the expansion process.

Abstract: Previous to the sending of an electronic mail, an attached file verifying unit retrieves a mail text to retrieve the presence or absence of an attachment representation indicative of the existence of an attached file, and if the attached representation has been retrieved, it issues for display a warning message urging the sender to verify the forget-to-attach. Furthermore, the attached file verifying unit compares the estimated number of attached files based on a number of attached files representation in the mail text with the actual number of attached files existing in the electronic mail, and if the actual number of the attached files is less than the estimated number of the attached files, it issues a warning message indicative of a lack of the attached files. In addition, the attached file verifying unit compares a file name in the mail text with a file name in the attached file, and if the two are not coincident with each other, it issues a warning message indicative of attachment of an erroneous file.

Abstract: The copy protection system and method combines the features of a conventional electronic data carrier with a dongle to form a secure storage medium. The storage medium has a unique identification, such as a device serial number. The host transmits a challenge signal to the storage medium and then checks the response received from the storage medium for a proper correlation between the useful data and the storage medium. A mismatch indicates that the data is present on a bootleg carrier instead of on its authorized carrier. Therefore, if the response signal in the challenge-response process does not correspond to the expected setpoint response, then the data are not authorized for processing.
