Abstract: A method of determining if one web site has the same information as another web site includes receiving a signal to select a form configured to find data in a file containing information displayed on a web site and accessed via a network, applying the selected form to the file and selectively identifying item information available in the file, copying identified item information to a first data file, the identified item information being related to a specific product or service, and comparing the first data file and a second data file to determine if the specific product or service of the first data file is related to the specific product or service of the second data file.

Abstract: The reliability of a data flow between a server and a client in a data communications network is increased. An application in a user terminal is arranged to receive information from a server, such as a push server or a streaming server, in the network. A user who should have an active connection to the server is monitored to determine if the user currently has such a connection. An appropriate action is taken if this is not the case. The user's connection to the data communications network is monitored. If connected to the data communications network, the user should also have an active connection to said server.

Abstract: A method for improving next hop selection between internet routers (R) defined by their respective IP addresses. A source is identified by a source IP address and a source port identification. A destination or target is defined by a target port identification. Equivalent routes toward the destination host are identified conventionally. Each of the equivalent routes is defined by next router IP address. The source IP address, source port identification and target port identification are logically combined to derive a connection identifier (HO) for a first router common to all paths. An set of additional logical operations are performed to derive next hop selection identifiers. Final next hop route selection is based on predefined criterion.

Abstract: The invention provides for on-access scanning of archives, such as “ZIP” files, for files containing viruses or other unwanted characteristics. In particular, disclosed are various techniques for beginning a scanning operation, and then monitoring the scanning operation to determine whether it is completing in a reasonable time. If the scanning operation is taking place within a terminal server type of environment, such as the Microsoft Terminal Server, where an application program is run in a virtual execution environment, then provision is made to identify client connections to the server so that error messages (such as denying file access due to a virus) can be presented to a terminal server client's terminal, rather than at the terminal server console.

Abstract: A network system receives incoming packets from multiple private networks with potentially conflicting Internet Protocol (IP) address spaces, and performs header and payload address translation operations to ensure that the IP address spaces of the incoming packets are made non-conflicting, such that the packets can be managed using a single network management platform. A router in the system receives the packets and performs Network Address Translation (NAT) on IP header information. Packets identified as being associated with a particular protocol, e.g., a Simple Network Management Protocol (SNMP), are redirected by the router to a Management Payload Address Translator (MPAT) that applies a fast parsing process to the packet payloads to identify IP address-related information therein, and if necessary applies an appropriate translation of the identified information before routing the packets to a network management platform.

Abstract: A framework is provided for describing multimedia content and a system in which a plurality of multimedia storage devices employing the content description methods of the present invention can interoperate. In accordance with one form of the present invention, the content description framework is a description scheme (DS) for describing streams or aggregations of multimedia objects, which may comprise audio, images, video, text, time series, and various other modalities. This description scheme can accommodate an essentially limitless number of descriptors in terms of features, semantics or metadata, and facilitate content-based search, index, and retrieval, among other capabilities, for both streamed or aggregated multimedia objects.
