A two-way cable network offering high-speed broadband communications delivered via virtual private networks over a multi-channel shared media system. Bi-directional transmission of packet to ATM cell based communications is established between a head end communication controller and a number of subscriber terminal units, whereby individual cells are prioritized and routed according to a virtual connection. Virtual connections are organized to support multiple virtual private networks in a shared media CATV system. The virtual private network to which a particular STU belongs is user selectable and has the flexibility of handling multi up/downstream channels with different MAC domains. The present invention can also handle non-ATM MAC domains via the same common ATM switch. To overcome the limited number of addresses inherent to common ATM switches, a mapping/remapping function is implemented in the port cards. Furthermore, downstream as well as upstream traffic are filtered at each STU. In one embodiment, information pertaining to downstream traffic is used to implement predictive scheduling in order to improve the timing associated with the request/grant cycle. In another embodiment, a user has the ability to select a quality of service that best suits the needs of the current application. In a further embodiment, the scheduling function is associated with each of the receivers in order to provide improved scalability.

A communication device has a first communication section that supports a first communication mode having a low communication rate and a second communication section that supports a second communication mode having a higher communication rate than the first communication mode. The communication device includes a packet generation section and a communication control section. The packet generation section generates a first portion containing authentication information used for connection authentication for the second communication mode and a second portion other than the first portion. The communication control section performs control to cause the first communication section to transmit the first portion and to cause the second communication section to transmit the second portion after the connection authentication succeeds using the authentication information contained in the first portion.

Video communication systems and methods for communicating between an individual in a local environment, and a remote viewer in a remote environment are provided. The system has an image display device; at least one image capture device which acquires video images for fields of view of a local environment, and any individuals therein; an audio system having an audio emission device and an audio capture device; a computer, which includes a contextual interface having a gaze adapting process, and image processor; and a communication controller which transmits and receives video images of the local environment and the remote environment, and data regarding video scene characteristics thereof across a network between the local environment and the remote environment; wherein the gaze adapting process identifies video scene characteristics of the local environment indicative of eye gaze image capture and altering the video images when the characteristics are indicative.

A system for protocol processing in a computer network has a TCP/IP Offload Network Interface Device (TONID) associated with a host computer. The TONID provides a fast-path that avoids protocol processing for most large multi-packet messages, greatly accelerating data communication. The TONID also assists the host for those message packets that are chosen for processing by host software layers. A communication control block for a message is defined that allows DMA controllers of the TONID to move data, free of headers, directly to or from a destination or source in the host. The context is stored in the TONID as a communication control block (CCB) that can be passed back to the host for message processing by the host. The TONID contains specialized hardware circuits that are much faster at their specific tasks than a general purpose CPU. A preferred embodiment includes a trio of pipelined processors with separate processors devoted to transmit, receive and management processing, with full duplex communication for four fast Ethernet nodes.

Systems and methods to authenticate and process requests received via social networking websites.

The present invention is a security system that utilizes an identity verification system having a biometrics component, such as but not limited to a face, fingerprint, or iris recognition system. The system connects a biometric data entry device such as a standard analogue or digital camera to a communication control device which captures, compresses and digitizes the biometric data as well as converts data from data input devices and sends the compressed and digitized biometric data along with the data from a data input device to a central processing unit for processing by a biometric recognition system and comparison to stored biometric data.

A communication terminal under the control of a wireless base station recursively has wireless base station capabilities in a parent network, constructs a daughter network within a scope of resources of the own apparatus assigned by the wireless base station, and assigns the resources to an other communication terminal under the control of the communication terminal having base station capabilities. This novel constitution allows to configure two or more networks guaranteed not to interfere each other, thereby allowing the coexistence of a plurality of personal area networks on a same frequency channel. At the same time, the novel constitution allows expanding a network area without increasing the scale of equipment.

A scalable, multi-protocol mobile switching center in a wireless communications network provides communications control for digital and analog wireless communications devices including devices that operate according to GSM and IS-41 standards. The hardware and software architecture of the switching center is designed so that processing that is unique to a particular protocol is performed at the lowest possible level, and remaining processing can use generic procedures. The switching center incorporates a home location register and visitor location register that are used in conjunction with software applications to determine the protocol of mobile communications devices using the wireless communications network. The mobile switching center can be used to provide a large scale distributed wireless network or a small scale wireless network. The switching center can also be used as an adjunct to a private branch exchange to provide in-building wireless services and call control. Graphical user interfaces make the wireless communications network easy to maintain.
