摘要： A computer-based system is configured for generating a first data structure having entries representing respective network nodes having layer 2 and layer 3 network addresses. The system generates a second data structure, having a plurality of data packet headers, by selecting source and destination pairs from the first data structure and combining the respective layer 2 and layer 3 network addresses from the respective selected source and destination pairs with randomly-generated numbers representing layer 3 payload data. The second data structure is supplied to a switch model configured for parsing the layer 3 network addresses according to selected hash functions. Hence, the computer-based system is able to evaluate the selected hash functions based on a time-independent analysis, eliminating the necessity of building an actual network in hardware or simulating network traffic over a period of time.

摘要： A method of determining a geographic location of an Internet user involves determining if the host is on-line, determining ownership of the host name, and then determining the route taken in delivering packets to the user. Based on the detected route, the method proceeds with determining the geographic route based on the host locations and then assigning a confidence level to the assigned location. A system collects the geographic information and allows web sites or other entities to request the geographic location of their visitors. The database of geographic locations may be stored in a central location or, alternatively, may be at least partially located at the web site. With this information, web sites can target content, advertising, or route traffic depending upon the geographic locations of their visitors. Through web site requests for geographic information, a central database tracks an Internet user's traffic on the Internet whereby a profile can be generated. In addition to this profile, the central database can store visitor's preferences as to what content should be delivered to an IP address, the available interface, and the network speed associated with that IP address.

摘要： A method and system for streaming media data to a fixed client and/or a mobile client. In one method embodiment, the present invention recites encoding media data to be streamed to a client into a first multiple description bitstream and into a second multiple description bitstream. The present method then determines the appropriate plurality of servers from a network of servers onto which the first and second multiple description bitstreams should be distributed. The present embodiment then recites distributing the first and second multiple description bitstreams to the appropriate plurality of servers positioned at intermediate nodes throughout a network such that a client is provided with access to the media data via a plurality of transmission paths. The present method is also well suited to redistribution of multiple description bitstreams to servers based upon time-varying demand, client movement, and the like.

摘要： A clustered computer system, bridge device and method include support for an atomic ownership change operation that ensures orderly and reliable ownership management of an input/output (I/O) bridge device. A lock indicator is associated with a bridge device, and is used to indicate a “locked” or “unlocked” status of the bridge device. Whenever the lock indicator indicates that the bridge device is unlocked, an atomic operation such as a read request to a lock indicator register is utilized to both set the indicator to indicate a locked status for the bridge device, and to associate the bridge device with a source node that initiated the atomic operation. In connection with the lock indicator, write access to one or more configuration parameter registers is controlled such that only the node that is associated with the bridge device is permitted to update such configuration parameter registers.

摘要： A method apparatus and computer program product for providing access to host attribute information in a storage area network is disclosed. The storage area network is composed of a plurality of hosts coupled to at least one initiator. Each initiator is coupled to one or more targets and each initiator has an associated identifier. In each host, the identifier of the initiator is related to other host attribute information. The identifier may be, for example, a world wide name. The host attribute information including the identifier is sent from each of the plurality of hosts to the one or more targets and stored in memory of an associated storage array. Either a host or requestor remote from the storage array may request the collected host attribute information from the storage array. A topology of the storage area network may then be formed from the host attribute information of each host.

摘要： In a multilink point-to-point protocol (PPP) network access server, a method is provided in one aspect of the invention allocating ports among various users that includes allocating primary ports among various users, and thereafter, allocating secondary ports among various users only until the number of allocated secondary ports reaches a prescribed maximum. Another aspect of the invention may be thought of as a back-channel allocation method that includes determining whether a back channel is actually being used by a first network client, and if not then allocating the unused back channel to a second network client. In a final aspect of the invention an auxiliary channel resource allocation apparatus for use with a multilink PPP access server, is provided that includes decision or detection logic determining the availability of an auxiliary channel resource previously allocated to a first user of the access server, the decision logic signaling such availability, and allocation or reallocation logic responsive to the signaling to allocate the available auxiliary channel resource to a second user of the access server. The foregoing and other objects, features and advantages of the invention will become more readily apparent from the following detailed description of a preferred embodiment which proceeds with reference to the drawings.

摘要： A wireless remote control is disclosed for controlling computers remotely over a data network. The wireless remote control system includes Remote Access Programs running on data network servers, which provide access to, and disposition of data objects. The wireless remote control system is particularly useful for overcoming the difficulty of handling data over a low bandwidth wireless link with the minimal display facilities of a wireless handset or Personal Digital Assistant and of providing linkage between data objects on one computer and applications residing on another computer under the direct supervision of the user without the data objects needing to traverse the low bandwidth link.
