Abstract: A system and method of authenticating a user of a data network which inserts control information into certain data packets being sent over the network. The control information is user-specific, including such items as user identity, password, originating CPU, or biometric information. Inserting the control information into data packets transmitted during the entire session permits continuous authentication.

Abstract: An integrated circuit system is provided for wireless data communication, comprising a set of hardware components and a port for connection to an RF antenna or an RF Front-End-Module, wherein at least a subset of hardware components is arranged for being shared for simultaneous wireless data communication based on a first protocol and a second protocol. Preferably, the first protocol includes a Wi-Fi standard and the second protocol includes a dedicated protocol for wireless audio communication.

Abstract: A system and method of providing secure communications between two or more hosts connected to a public network, where a secure virtual network (SVN) is established among the two or more hosts.

Abstract: An architecture, system, and method are provided for transparently mapping a network identification number of a host to an access point of an internet. The host can be moved from a first point to a second point on the internet without having to reconfigure routing tables or to update routing protocols. The network identification number of the host does not change as it is moved from the first point to the second point. Thus, the network identification number of the host does not perform routing. Instead, routing occurs by targeting the exit end module onto which the host is connected, i.e., at the second point. The exit end module thereby contains configuration registers which store mapping tables that note the new destination address of any data being sent to the new host location, and properties such as security and priority codes.

Abstract: An architecture, system and method are provided for efficiently transferring packets of data across a communication network. Portions of the communication network is structured such that there are hierarchical levels of high speed Routing Switches existing throughout the network. Distributed routing of packets is achieved by comparing identification numbers of Routing Switches with the destination address of a data packet. Once routing is achieved within the transport ID based network, transfer to a destination termination device occurs through a single look-up table only when departing the network. The routing operation between termination devices can therefore be achieved using a single mapping operation and is backward compatible with devices external to the network and protocols used by those devices.

Abstract: A packet architecture, communication system, and method are provided for determining the location at which a network is disrupted, disabled, and/or severed. The packet can contain control bits and error identification bits which note the location at which disturbance exists, and informs the originating module to take alternative path if necessary. The alternative path can be applied to either re-sending the existing packet or sending future packets between certain modules connected to the network, wherein the network preferably includes one or more ring topologies interconnected with one another between termination devices. The termination devices allow communication across subnets which form an intranet or across a global system, or internet. Although redundant transmission channels are used, each transmission channel preferably does not send redundant packets, nor are the transmission channels dedicated as uni-directional.

Abstract: An architecture, system and method are provided for transparently mapping addresses across multiple addressing domains and/or protocols. A destination of a packet can therefore be transferred from a first addressing domain within one network to a second addressing domain within another network, without inserting knowledge into the packet of the relationship between the two separate and independent domains. Transmission modules within one network can be identified with unique identification numbers or addresses assigned during configuration of those modules. The identification numbers assigned internal to the network can be mapped and placed upon the packet as the packet enters the network. Mapping, however, is minimal, knowing that relatively few external devices are connected to select internal devices and/or modules. The packet can then be mapped into the network, where it is then transferred across the network whereupon it is mapped to another network or termination device external to the network.

Abstract: An architecture, system and method are provided for efficiently transferring packets of data across a communication network. The communication network is structured such that there are hierarchical levels of high speed switches existing throughout the network. Distributed routing of packets is achieved by comparing identification numbers of only select switches with the destination address on a field-by-field basis. Not all fields need be compared at all switches. Once routing is achieved within the structured network, transfer to a destination termination device occurs through a single look-up table only when departing the network if multiple termination devices are present at that exit node. The routing operation between termination devices can therefore be achieved using a single mapping operation (if more than one termination device must be selected) and is backward compatible with devices external to the network and protocols used by those devices.

Abstract: Architectures, systems, and methods are provided for securing and prioritizing packets of data sent through a communication network. Each packet is assigned a security code and priority code as it enters the network. The security code or priority code may remain the same or change as it travels from node-to-node across the network. By assigning security and priority codes to each packet, maximum bandwidth allocation can be achieved among the nodes in a packet-switched environment. The assigned security and priority codes enter and travel through the network according to modules which have a hierarchical class or grouping. Thus, the security and priority information may be sent solely within one class or among classes depending on where, within the classes the data path exists.
