Synchronous network for digital media streams
InactiveUS6611537B1Avoid collisionPulse modulation television signal transmissionTime-division multiplexData streamNetwork clock
A network adapter for a synchronous logical ring network operates on existing physical twisted-pair telephone topologies. Information propagates around the logical ring, reaching every device on each revolution around the network. Network devices are full-duplex, transmitting and receiving information on every clock cycle. Network devices arbitrate to be elected the network clock device. By synchronizing all network devices to a single reference clock, and providing fixed frames of information propagating around the network at consistent time intervals, the logical ring network ensures that information propagates from one device to another at consistent time intervals. The fixed-length frames are divided into two independent streams: a data stream for the distribution of real-time continuous digital media streams; and a system command stream for the distribution of system commands.

InactiveUS6614781B1Interconnection arrangementsDc level restoring means or bias distort correctionNetwork operations centerNetwork architecture
The present invention describes a system and method for communicating voice and data over a packet-switched network that is adapted to coexist and communicate with a legacy PSTN. The system permits packet switching of voice calls and data calls through a data network from and to any of a LEC, a customer facility or a direct IP connection on the data network. The system includes soft switch sites, gateway sites, a data network, a provisioning component, a network event component and a network management component. The system interfaces with customer facilities (e.g., a PBX), carrier facilities (e.g., a LEC) and legacy signaling networks (e.g., SS7) to handle calls between any combination of on-network and off-network callers.The soft switch sites provide the core call processing for the voice network architecture. The soft switch sites manage the gateway sites in a preferred embodiment, using a protocol such as the Internet Protocol Device Control (IPDC) protocol to request the set-up and tear-down of calls. The gateway sites originate and terminate calls between calling parties and called parties through the data network. The gateway sites include network access devices to provide access to network resources. The data network connects one or more of the soft switch sites to one or more of the gateway sites. The provisioning and network event component collects call events recorded at the soft switch sites. The network management component includes a network operations center (NOC) for centralized network management.

Distributed network communication system which allows multiple wireless service providers to share a common network infrastructure
System and method for providing access to multiple wireless service providers (WSPs) on a shared network infrastructure. The system includes a plurality of access points (APs) coupled to a network which may be distributed in airports, mass-transit stations, businesses, etc. The network may couple to a wide area network, such as the Internet. Each AP may include a plurality of virtual APs (VAPs), each corresponding to a WSP. A portable computing device (PCD) of a user stores identification information indicating a WSP of a plurality of possible WSPs, and which may include an access level of the user. Each AP "listens for" or detects identification information associated with numerous WSPs. When the AP receives the identification information from the PCD, it determines the VAP / WSP for the PCD using the identification information. Network access is then provided to the PCD through the determined WSP at the determined access level.

Secure network access devices with data encryption
InactiveUS20050114663A1Avoid readingUser identity/authority verificationInternal/peripheral component protectionUsage dataEncryption
Secure point to point network communications. Secure point to point network communications are accomplished by sending data across a secure link. Trusted partners at the link are matched to each other. To ensure that no un-trusted partners are on the link, authentication is performed. One of the points may be a secure tap. The secure tap authenticates a trusted partner by receiving a hardware embedded encryption key or value derived from the hardware embedded encryption key from the trusted partner. Data sent on the trusted link is encrypted to prevent interception of the data. The secure tap polices the link to ensure that no un-trusted partners are attached to the link and that the trusted partner is not removed from the link. If un-trusted partners are added to the link or trusted partners removed from the link, the secure tap ceases sending data.

InactiveUS7054924B1Reliable transportationMultiple digital computer combinationsTransmissionReliable transmissionExtensible markup
A method is disclosed for carrying out network device provisioning and configuration, and communication of other information to a network device, automatically and in an assured manner. A configuration service receives a request from a network device to provide configuration information. The configuration service retrieves a template representing the configuration from a storage location, e.g., a directory service. The configuration service also retrieves one or more parameter values specific to the device. Device-specific values are instantiated for the generic parameters in the template, based on the retrieved values. The resulting configuration is stored in XML format using XML tags to delimit configuration commands, tested for well-formed-ness, and syntax checked. A reliable transport protocol carries the configuration information to the device. At the device, a configuration agent syntax checks the embedded configuration information, and then applies the configuration information to the device. As a result, automatic network provisioning may be accomplished remotely, without requiring a skilled technician to visit customer premises to carry out configuration. The process may be integrated with an event service to enable multiple devices to concurrently receive re-configuration without special synchronization logic.

A fast authentication and access control method of authenticating a network access device to a communications network having an access point communicating with a remote authentication (home AAA) server for the network access device. The method includes the step of receiving an access request having an authentication credential from the network access device at the access point. The authentication credential includes a security certificate having a public key for the network access device and an expiration time. The security certificate is signed with a private key for the remote authentication server. The access point locally validates the authentication credential by accessing the public key of the remote authentication server from a local database, and checking the signature and expiration time of the security certificate. If the authentication credential is validated at the access point, the access point grants the network access device conditional access to the network by sending an access granted message to the network access device. The access granted message includes a session key encrypted with a public key for the network access device. The session key is stored in a database associated with the access point. The access point contacts the remote authentication server to check a revocation status of the security certificate for the network access device. If the access point receives a message from the remote authentication server that the authentication credential for the network access device has been revoked, it suspends network access for the network access device.
