The disclosure describes a method for enabling internet access to information hosted on a computer or a storage device (CSD), even without having a web server software on the CSD. The CSD is registered with a server and assigned an ID by the server. Information about all CSDs is stored in a database on the server. A unique resource locator (URL) is created for each file intended to be shared. The URLs of all hosted files are stored in a file called the registry file residing on the CSD. An intending recipient may enter the URL of the desired file in a web browser. The URL is sent from the web browser to the server. The server forwards the URL to the CSD The file is retrieved from the CSD and sent to the server. The server forwards the file to the recipient computer, where the web browser displays it.

A method to automatically allocate servers to network services in a data center in real time and without need for operators for a load sharing device is provided. In the method, fluctuations in quantity of requests arriving at the network services can be monitored, the value of the quantity of requests for a subsequent fixed time interval can be predicted and, in accordance with the magnitude of the predicted value of the quantity of requests, the quantity of servers allocated to the network services can be controlled. Here, where traffic of the quantity indicated by the predicted value of the quantity of requests arrives at the network services, the number of servers allocated to the network services can be set in such a way that the average response time to the user terminals is equivalent to a response time threshold value or less set in advance by the operations manager.

System and computer program product for automatically adjusting allocation of processing power in a server. The server includes means for monitoring utilization of the processing power in the server and reporting the utilization of the processing power to the system, or means for monitoring availability of the processing power in the server and reporting the availability of the processing power to the system. The system comprises means or program instructions, responsive to a report that the processor utilization is above a first predetermined upper threshold or the processor availability is below a first predetermined lower threshold, for determining if the server can accommodate allocation of additional processing power, and if so, generating a request to allocate additional processing power to the server. The system also comprises other means or program instructions, responsive to a report that the processor utilization is below a second predetermined lower threshold or the processor availability is above a second predetermined upper threshold, for determining if the server can accommodate a de allocation of processing power, and if so, generating a request to de allocate some of the currently allocated processing power from the server. The system and program product also automatically adjust allocation of memory in the server.

An embodiment of the invention is a multipoint conferencing system having the ability to dynamically assign an endpoint to a “closest” one of multiple conference servers is disclosed. In one embodiment, when an endpoint first connects to the conferencing system, its Endpoint ID (e.g., IP address, E164 address) is determined. Based on the Endpoint ID, the conferencing system selects the most appropriate ones of the conference servers to act as the endpoint's “local” conference server. That is, the endpoint will transmit and receive conference data from other endpoints via the selected conference server. If no other endpoints across the network happen to be viewing a particular endpoint's video stream, the stream is not provided to the network, thus conserving network bandwidth. An embodiment further creates appropriate linking between conference servers automatically, manages conference server topology and determines link type (e.g., Unicast vs. Multicast linking) automatically.

A server allocation controller provides an improved distributed data processing system for facilitating dynamic allocation of computing resources. The server allocation controller supports transaction and parallel services across multiple data centers enabling dynamic allocation of computing resources based on the current workload and service level agreements. The server allocation controller provides a method for dynamic re-partitioning of the workload to handle workload surges. Computing resources are dynamically assigned among transaction and parallel application classes, based on the current and predicted workload. Based on a service level agreement, the server allocation controller monitors and predicts the load on the system. If the current or predicted load cannot be handled with the current system configuration the server allocation controller determines additional resources needed to handle the current or predicted workload. The server cluster is reconfigured to meet the service level agreement.

A conference call is established in response to receiving a request 4 from a first communication terminal 3a. The request 4 preferably is an SMS or MMS and comprises one or more identifiers 5, 6, 7, e.g. telephone numbers, relating to a plurality of other communication terminals 3b-3d. A conference call server I allocates a conference call channel and an associated identifier, such as a telephone number. Messages 10a-10c alerting the conference participants are then sent to the other communication terminals 3a-3c, each message including the identifier associated with the conference call channel. Access to the conference call may be restricted to authorised users by compating identifiers, such as CLIs, of incoming callers to the identifiers provided in the request 4 and allowing access only if there is a correspondence or match. In the event that an incoming caller has withheld their CLI, or it is otherwise nondeterminable, access is refused and a message may be sent reminding conference participants who have yet to join the conference call not to withhold this information. Alternatively, the server calls the participants at the appropriate time.

User specific internet service provider (ISP) account information is stored on the user's smart card, but the ISP specific connection information is stored within a network computer client device (NC). When the NC is first powered on and used, it calls the relationship server to receive connection information corresponding to the ISP that is either specified on the first user's smart card or is otherwise chosen by the first user. This connection information is preferably stored in non-volatile memory within the NC, so that even if the NC is powered down, it maintains the ability to connect to the ISP designated by its previous user. Each ISP is designated by a unique enterprise identification number assigned by the relationship server. When a subsequent user inserts his smart card into an NC, the NC compares the enterprise identification number on the smart card to the enterprise identification number within the NC. If the enterprise identification numbers match, the NC connects to the IAP already stored in the NC without dialing the relationship server. Only if the enterprise identification numbers do not match must the NC then dial the relationship server to download connection information for the ISP designated by the smart card enterprise identification number. In the preferred embodiment, the ISP contents of the smart card are digitally signed by the ISP. If the enterprise identification numbers match, then the ISP contents of the smart card are cryptographically authenticated using the public key within the authorized usage certificate for the ISP. If the cryptographic authentication fails, then the NC reprograms the smart card.

The method comprises the steps: receiving a sensitive set of characters in said local server; replacing a part of said sensitive set of characters with a token to form a tokenized set of characters, said token belonging to a subset of possible tokens assigned to the local server by the central server; transferring at least one of said sensitive set of characters and said tokenized set of characters to the central server; and canceling said sensitive set of characters from said local server within a limited time from said transferring, while maintaining said tokenized set of characters in a local database connected to said local server.

A method is provided for performing an authentication procedure according to location registration and update for a mobile subscriber station (MSS) in a broadband wireless access (BWA) communication system. The system includes the MSS operating in idle mode to minimize power consumption, paging groups each being formed by a plurality of adjacent cells in which a plurality of MSSs are paged, base stations (BSs) for paging the plurality of MSSs within each paging group, and a server for controlling location registration and authentication for the plurality of MSSs. The server determines whether to approve a request for transition to the idle mode received from the MSS through a BS. If the server approves the request for the transition to the idle mode, it allocates authentication information to the MSS through the BS and registers location of the MSS. When it is determined that the MSS has moved to a different paging group, the MSS sends a location update request including a resulting value computed using the authentication information allocated from the server. The server authenticates the MSS according to the authentication information included in the location update request and registers the changed location of the MSS authenticated successfully.
