A cryptographic encoded, ticket issuing and collection system for real-time purchase of tickets by purchasers at remote user stations in an information network that includes a plurality of remote user stations coupled to a server in an information network, e.g., the Internet, for purchase of services, products, or tickets to an event. An operator of the remote user station selects a ticket for purchase to an event using standard protocols of information network. An electronic ticket is transmitted to the operator and includes a cypher code created using a public key cryptography system. The operator displays the electronic ticket for verification purposes and proceeds to print out the ticket at the station. The ticket is presented to a ticket collector whereupon the ticket is scanned by a portable terminal for decoding the cypher code using a public key reloaded into the terminal by the producers of the event. The decoded cypher code is compared against the event description stored in the portable terminal and if equal, the ticket is accepted for admission to the event. The ticket information is stored in the portable terminal and subsequently uploaded to the information system to check for duplicate tickets.

The present invention provides a method and apparatus for increasing the performance of world-wide-web traffic over the Internet. A distributed network of specialized nodes of two types is dispersed around the Internet. A web client's requests are directed to a node of the first type chosen to be close to the client, and the client communicates with this node using a standard protocol such as HTTP. This first node receives the request, and communicates the request to a node of the second type chosen to be close to the request's ultimate destination (e.g., a web server capable of generating a response to the request.) The first node communicates the request to the second node using a different, specialized, protocol that has been designed for improved performance and specifically to reduce traffic volume and to reduce latency. The second node receives communication from the first node using this specialized protocol, converts it back to a standard protocol such as HTTP, and forwards the request to the destination computer or server. Responses from the destination to the client take the corresponding reverse route, and also are carried over a specialized protocol between the two nodes. In addition, these nodes can employ other techniques such as web caches that avoid or improve some communication steps. Thus, specialized, proprietary, or complex protocols and techniques can be quickly deployed to enhance web performance without requiring significant changes to the clients or servers.

Exemplary methods and systems for acquiring network credentials for network access are described. The exemplary method comprises receiving network configuration information from a network device on a communication network, generating a credential request, transmitting the credential request to a credential server over a standard protocol of the network device, receiving the credential request response, and providing a network credential from the credential request response to the network device to access the communication network.

A presence tracking architecture for datagram-based protocols. A client application seeking to know the presence or lack thereof of a device and/or service utilizes a standard protocol in a non-intuitive way to trigger notification of the device and/or service before any associated timeout expires. At first presence, a multicast message is broadcast to notify all devices. Subsequently, on-demand notification may be requested by a client application by sending directly (e.g., in unicast) to the device before its timeout has expired a message that is normally only sent in multicast. If capable, the device can then respond normally with a unicast message indicating it is on-line. If the response is not received, the device and/or service is determined to be off-line.

In some illustrative embodiments, an IP-layer based network selection and multihoming method is provided that enables a flexible and secure dynamic selection of one or more serving networks for use by a client node. The method is independent of any link-layer technology. A serving network can be an ISP network, a NAP network exchange facility, a VLAN, or the like. Network information is advertised to a client node, the client node is authenticated and authorized for use of an access router, and a secure tunnel is established between the client node and the access router. The method can be implemented by using standard protocols, and can work over any existing or future link-layer technologies that are able to carry IP datagrams, without any modification.

A portable, application-specific USB autorun device, following connection to a computer terminal, automatically initialises or presents itself as a known type of device and then automatically sends to the terminal a sequence of data complying with a standard protocol, that sequence of data automatically causing content to be accessed or a task to be initiated. The device (i) includes a standardised USB module that includes a USB microcontroller, the standardised module being designed to be attached to or embedded in multiple types of different, application specific packages but (ii) excludes mass memory storage for applications or end-user data.

The systems disclosed here provide a complete standards-based end-to-end scalable system for storage, delivery and in-home distribution of digital content over IP networks using standard protocols such as Real-time Transport Protocol (“RTP”) or IP-encapsulated MPEG-2 Transport Stream, or traditional MPEG-2 networks. Mechanisms are provided for receiving content from one security domain, re-encrypting that content uniquely for a receiving device, persistently storing that content, and playing back that content at a later time to and within another security domain. The systems also provide the ability to stream the persistently-stored content from the initial receiving device to another device that has been authenticated as part of a, e.g., home network. This allows a media server, e.g., a dual-tuner set-top box (“STB”) with hard drive, to deliver recorded content to any TV in the house by streaming to media clients such as STBs.

An Application Programming Interface (API) provides interoperability between different monitoring and administrative components of a data warehouse system that utilizes different standard protocols. One of the protocols is the well known data connectivity protocol, Open Database Connectivity (ODBC) that defines a standard interface between applications and data sources.

A method and system are provided for updating software configurations of line-replaceable unit (LRU) computers in a restricted architecture network such as an in-flight entertainment system (IFES). Operating in an efficient and parallel manner, each of the LRUs independently creates an individual configuration file that identifies current software components. Each of the LRUs transmits its respective configuration file to a configuration server either automatically upon startup or manually upon request. The configuration server updates a system configuration data file with the current configuration files received from the individual LRUs. In a downloading method, a download server sends a list of desired software components to the LRUs. Each of the LRUs independently and simultaneously transfer (download) the needed software from the download server. The LRU independently requests the download server to download the needed software components. To improve scalability and reliability, the file transfers utilize standard protocols, such as FTP.

A data transaction processing system in which transaction data is entered by the user in response to prompts in a template which is tailored to each user application. The template and entered data are accumulated into data transactions that are immediately transmitted upon completion to an external database server for processing and storage. The data transaction is received via standard protocols at the database server which, depending upon the application, stores the entire data transaction, explodes the data transaction to produce ancillary records which are then stored, and/or forwards the data transaction or some or all of the ancillary records to other database servers for updating other databases associated with those database servers. In response to requests from the transaction entry device, the database server may return data streams for use in completing the fields in the data transaction or in presenting a menu on the display which was read in from the database server or a remote phone mail system. The transaction entry device is integrated with a telephone and is accessed via a touch screen, an optional keyboard, a magnetic card reader, voice entry, a modem, and the like.

A plurality of such database servers under the control of broad operations system server (BOSS) software and a plurality of form-driven client computing devices are provided to create an open platform system for receiving and transmitting transaction data to or from the client devices, other applications and databases. Advantageously, a locator server computer serves to retrieve IP address numbers, PSTN numbers and other network identification information for use in identifying and locating, e.g., an originating user and a destination client device. A robust security and authentication scheme along with robust storage protects the transmission of sensitive or confidential data.

A modified preamble is used by extended devices that operate in mixed mode environments and green field environments, to accommodate beamforming of transmissions. In one process, an extended wireless device processes data for transmission of that data as a packet, wherein the extended wireless device is a device configured to communicate using a standard protocol understood by each node device and an extended protocol not understood by legacy node devices. If the packet is to be directed at an extended device, the extended wireless device sends a preamble of that packet that is usable in an extended mode at extended devices and usable at a receiving legacy device to determine that the receiving legacy device is not the destination of data to follow the preamble. Once the receiving legacy device is expected to be deferring the network, the extended wireless device can beamform its signal or otherwise vary from the legacy protocol in communications with extended devices.
