  • Patent number: 6449646
    Abstract: An apparatus for routing a transaction message, such as for example a telephone call, e-mail, web chat request, video conferencing session, or non-call event, includes a queue engine and a transaction message router. The queue engine provides an integrated mechanism for queuing transaction messages of varying transaction types within a number of queues according to transaction type. Each queue within the queue engine may be dedicated to queuing transaction messages of a specific transaction type. The transaction message router functions to identify a queue within the queue engine within which a transaction message is to be stored. The identification of a queue by the router may be performed with reference to the transaction type of a transaction message, and with reference to context or addressing information associated with a transaction message.

  • Patent number: 6442602
    Abstract: An Internet domain name server platform which intercepts web browser HTTP queries to unrecognized, unregistered subdomain name and provides redirection of the query to a recognized and registered domain name or a subdirectory of a recognized and registered domain name. A server script is launched in response to the event of the request to an unrecognized subdomain name, which dynamically resolves the unknown address rather than returning a standard “Error 404: File Not Found” message to the requesting web browser. The script accesses a database of virtual subdomain names which are mapped in the database to actual subdirectories on the same or a remote server. For example, if a query to is received, and is not recognized as a registered domain name by the standard DNS server, the script will resolve it and map it to, or any other file on a web server which is actually registered.

  • Patent number: 6418466
    Abstract: A method of discovering native or non-native authentication server domains and managing information about such domains in a computer network. The various domains are “discovered” by issuing requests from the client to one or more of the servers in the network. Each response is then characterized as being from a native or non-native server, and a list of each such server type is then compiled at the client. The administrator may modify the list, for example, by adding or removing server domains, or may apply a discovery “policy” to tailor the way in which a user may access and interact with the discovered information.

  • Patent number: 6385649
    Abstract: A method for compressing a routing table involves constructing a binary tree representation of the routing table. The compression method makes three passes through the tree. In a first pass, the compression method propagates routing information down to the tree leaves. During this pass, the program assigns every leaf node in the tree an associated next hop or an inherited next hop from a higher level ancestral node. In a second pass, the compression method migrates prevalent next hops up the tree. This bottom up pass involves forming a set of next hops at a parent node by supernetting the sets of next hops A and B for a pair of child nodes corresponding to the parent node, according to the following operation: A*B=A∪B, if A∩B=&phgr; A∩B, if A∩B≠&phgr; where A*B is a set of next hops formed at the parent node. In the third pass, the compression method eliminates redundant branches in the tree.

  • Patent number: 6356963
    Abstract: An apparatus handles long latency interrupt signals in a computer which posts I/O write operations. The apparatus includes a posting buffer for posting write operations and circuitry for ensuring that End-of-Interrupt (EOI) write operations (and other interrupt controller directed I/0 operations) are properly synchronized to prevent false interrupts from reaching the processor. Upon receipt of the EOI write operation, the apparatus verifies that the posting buffer is empty before it imposes a pre-determined delay to ensure sufficient time for the cleared the interrupt signal to be transmitted over the interrupt serial bus. Next, the apparatus checks the interrupt serial bus for activities. If the interrupt serial bus is idle, the EOI write operation is issued to the interrupt controller. Alternatively, the apparatus waits until the serial bus becomes inactive for two back-to-back cycles before allowing the EOI write operation to be issued to the interrupt controller.

  • Patent number: 6356929
    Abstract: A computer system on a network uses IP multicast to recruit other computer stems to share in the processing of a job. If a computer system on the network wants to be available to process shared jobs, it first registers for job sharing by invoking an IP multicast router at a particular IP address. All messages sent to the IP multicast router are broadcast to all computer systems that are registered with the router. When a computer system has ajob to share, it recruits other computer systems to help process the job by sending a message to the IP multicast router that corresponds to a request to share the job. The candidate computer systems that receive the recruiter's broadcast determine if they can share the job according to one or more job sharing parameters. These parameters may relate to the job itself, network performance, security, or other criteria for sharing. If a computer system meets the parameters for taking on the particular job, it responds to the recruiter.

  • Patent number: 6351773
    Abstract: Methods for providing restricted access for a network device such as a cable modem or customer premise equipment on a data-over-cable system. An unknown or new network device is assigned a restricted network address such as a restricted Internet Protocol address. The restricted network address allows the network device to access less than all of the available features on the data-over-cable system. A connection timer is started on the data-over-cable system for a restricted connection to the network device. The connection timer restricts access to the data-over-cable system over a timed interval. A restricted connection is created between the data-over-cable system and the network device including the temporary restricted network address and the connection timer, thereby providing restricted access to the data-over-cable system over a timed interval.
