The communication device is designed with circuit components and logic that allows two or more subscriber numbers to be concurrently programmed into the device. Each subscriber number is individually supported, with the logic also providing some overlapping functionality. A user selectively utilizes one of the subscriber numbers to originate a new call out and / or accept an incoming call to that subscriber number and may toggle between subscriber numbers to communicate on.

A method of controlling concurrent users of a distributed resource on a network is disclosed. In one aspect, there are one or more local lock managers executing on corresponding hosts and cooperating as a distributed lock manager. The resource is limited to a maximum number of concurrent users. A user identification for each user is associated with one host. In response to a request associated with a particular user associated with a first host, a lock is requested from a first local lock manager process executing on the first host. A related method of handling a request for a count-limited resource includes receiving a request from a client process for the computer resource. If it is determined that the request exceeds a maximum count for the resource, then it is determined whether a current time is within a retry time period of the client's first request. If it is determined the current time is within the retry time period, then it is automatically determined again whether the request exceeds the maximum count for the resource. If it is determined that the request does not exceed the maximum count, then the resource is provided to the client process.

A method and system using one or more load cells coordinates load testing of one or more sites under test over a network such as the Internet in accordance with one or more load test requests. In one embodiment, such method and system facilitates an economic, efficient, and accurate evaluation of the capacity of the SUTs to support concurrent users of the SUTs. A load test request is received from a User and provides information concerning a load test to be performed on a site under test (SUT). A load test is generated, and the load test is allocated to one or more load cells. The load cells perform the load test by sending load test data to the SUT and receiving responses from the SUT. Portions of a load test may be allocated to different load cells, which may be geographically remote from the SUT and / or geographically diverse. Multiple concurrent pending load tests may be processed for the same SUT. A load cell may concurrently perform all or a portion of multiple different load tests for multiple different SUT's simultaneously. A reporting function generates a report based on the responses received from the SUT. The reporting function may in addition or alternatively allow the User to view real-time results during load test execution.

The invention relates to network based content inspection (NBCI). More specifically, the invention provides systems and methods for improved NBCI in complex networks that are typical for enterprises and service providers. These networks are shared by large numbers of concurrent users who send and retrieve application content of various sizes via a variety of communication protocols. This invention improves the efficiency of the NBCI of an individual communication session by learning from the processing results of other communication sessions which may be carried via different network protocols. In addition, the invention provides methods that do not weaken the overall security for the network and that improve the stability of NBCI systems by minimizing the risk of system resource exhaustion if subjected to a burst of large payloads. The invention also improves perceived network stability by preventing the system resources from being “live-locked” by a few large content inspection tasks. Further still, the invention improves the cost-effectiveness of NBCI by allowing the optimization knowledge gained by one NBCI node be shared with other nodes.

To address the scarcity of radio frequency (RF) spectrum, the disclosed systems offer unique ways to mitigate interference between television broadcasters (including their direct audience and viewers served via cable television) and other concurrent users of the RF spectrum, e.g. for one-way or two-way wireless communication. A preferred embodiment makes use of the “framing” characteristics of the “letterbox” video display format. RF emissions of the simultaneous RF spectrum user are keyed “on” only or substantially only during the time intervals when the blanking intervals and / or letterbox-border video lines are being scanned on the display, i.e. when the potentially affected (interfered with) television display is in the letterbox-frame-scanning portions of each video field. The concurrent uses may support services for voice (including telephony, music etc.), data (including Internet, intranet, etc.); image or control; fixed, portable, mobile or nomadic; narrowband, broadband or ultra-wideband; radiodetermination, diathermy, etc. Additionally, the concurrent user's emitted power and receiver sensitivity is continuously adjusted according to the broadcast television signal.

A computer system including several nonconcurrently active hard disk drives ordinarily loaded with unique software bundles. Each active hard drive introduces an especial operating system setup and applications installation which is unconditionally denied access by activities obtained under another hard disk drive's software instructions. An absolute isolation between two or more user's application programs and data files is achieved while sharing a common set of computer system hardware and peripherals. Each category of nonconcurrent user operates independently without a threat of corruption from activities of another prior or subsequent user utilizing the same computer system for another disparate activity. In an IDE / ATA interface environment, a typical arrangement includes a setting of ROM-BIOS to only recognize a MASTER drive with a subsequent user determined swapping of MASTER and SLAVE modes between at least two hard drives utilizing a manual switch-over to obtain operation under operating system and programs uniquely installed on each of the intently selected MASTER drives, while denying access to the alternant SLAVE drive. In an SCSI interface environment, several drives set with the same SCSI-ID number are selected between by manually controlling a completion of the SCSI bus SEL line to the active intended drive and interrupting the SEL line to designated inactive drives. Virus corruption of one primary drive is fire-walled against inadvertent transfer into an alternate primary drive thereby assuring system operating integrity for one user category in spite of virus contamination, command errors, or careless or malicious hacking introduced by another user category.

The present invention is directed towards a “flash crowd” technique for handling situations where the cache receives additional requests, e.g.,. nearly simultaneous requests, for the same object during the time the server is processing and returning the response object for a first requester. Once all such nearly simultaneous requests are responded to by the cache, the object is flushed from the cache, with no additional expire time or invalidation action needed. This technique of the present invention enables data to be cached and served for very small amounts of time for objects that would otherwise be considered non-cacheable. As such, this technique yields a significant improvement in applications that serve fast changing data to a large volume of concurrent users, such, for example, as real time stock quotes, or a fast evolving news story.

A system, method, and processor readable medium containing processor readable program code embodied therein are provided that enable network users to view one or more network user's status and to establish communications with the one or more network users using a user indicator in an electronic document (e.g., electronic mail message, hypertext markup language document). The user indicator may be a network user's login identification presented as a hypertext link to one or more communication options. The system may include an identification module for identifying the one or more network users. The identification module may identify a network user's login identification (e.g., the network user's name, employee number) and provide the network user's status using the user indicator. A status module, responsive to the identification module, provides the status of the network users. The status module may provide a visual indication of a network user's status using, for example, color coding, formatting, symbols, etc. A communication module for establishing a communication link with the one or more network users using the user indicator may also be provided. The communication module may be used to establish a variety of communications with one or more of the network users. For example, a user may chat, telephone, transmit an electronic mail message, share one or more application programs, whiteboard presentations, facsimile, or page to one or more of the network users by selecting the user indicator using a conventional computer mouse or keyboard.

A Peer-to-Peer protocol such as BitTorrent is used to assist streaming. Peers download streaming content from the P2P network while simultaneously playing the downloaded content. As the stream plays, an end system downloads any missing pieces directly from a server or other infrastructure node. This method roughly squares server capacity and can be refined to require on average 0(1) servers regardless of the number of concurrent users. Thus BitTorrent assisted streaming scales better than traditional server-client and other infrastructure-only solutions, each of which requires a number of infrastructure nodes that scale linearly as a function of the number of users. Unlike End-System-Multicast, BitTorrent assisted streaming does not subject users to the vagaries of intermediate unreliable, potentially bandwidth-constrained end-systems; the departure of any single end-system has minimal impact on overall performance; and BitTorrent has a well-crafted incentive mechanism for encouraging users to contribute their upstream capacity.

A system and method are described for implementing a distributed database caching system with the capability to support and accelerate read and update transactions to and from one or more central Database Management System (DBMS) servers for multiple concurrent users. The system and method include a resource abstraction layer in a database client driver in communication with remote server units (RSUs) having a cache database. RSUs respond to user requests using the cache database if possible. If the cache database does not have the needed data, the RSU sends the request to a database subscription manager (DSM) in communication with the DBMS server. The DSM responds to the request and sends predicate data based on queries processed by the DBMS server for use in updating the cache databases.

A computer sharing system which adapts a computer's hardware resources to providing virtual dual system operation for several non-concurrent system users. A separate hard disk drive including a full complement of boot, operating system, program and data file software is provided for each of the non-concurrent system users. Access by one system user to another system user's hard disk drive and attendant files is absolutely denied thereby preventing corruption of one user's hard disk dive files by another user's carelessness or malicious intent, or through unique setup adaptation of one user's program files which may otherwise interact with and impose unwanted changes on another's program file's operational performance. Each of the separate hard disk drives may be uniquely formatted to service totally different operating systems, including boot track code, in support of various operating systems including MS-DOS, Windows-NT, OS / 2, Unix and others. By definition, each separate hard disk drive may be a physically distinct hard disk drive unit, or be more economically embodied as several separately utilized media platters driven by a common hard disk drive mechanisim and having user distinctive READ and WRITE channel control for each media platter. The absolute denial of a system user's access to another system user's assigned hard disk drive may be cracked open to an limited extent whereby READ-ONLY access may be permitted. Additionally, a third hard disk drive may be enabled to be shared by one or more system users in any combination of READ-ONLY, and READ and WRITE modes. My objective is to deliver the independent performance which until now was proffered only by two completly separate computers in the economic form of one set of computer hardware offering at least two virtually separate operating systems and sets of supporting software whereby one system user is absolutely blocked from corrupting another system user's uniquely configured software and data files.
