A convenient and low cost computer security system deploys a menu of security tools within a local network that can be selected by a user connected to the network. A network architecture of the invention is structured to provide highly effective and flexible security features while greatly simplifying the user experience. Separate security service pathways provide different combinations of security service features and traffic from each user is directed to a pathway providing the desired features.

A central server stores a database of global IP addresses for establishing TCP/IP sessions with other users of computer networks. One user system transfers a data call request to the central server system over a public data network. The central server system identifies the global IP addresses of the calling and called users and determines which ones of the calling and called users is connected to the public data network via a firewall. Depending upon the presence of firewalls, the central server configures the data call to enable direct, point-to-point packet transmission of network packets between the calling and called users without relaying them through the central server.

User connection sessions with a gateway in a computer network are preserved even after a temporary failure of the gateway. User status information is stored in a status table in a RADIUS server during times that an authenticated user session is established with the gateway. A failure of the gateway is detected wherein user data stored in the gateway is lost. The gateway sends a request to the RADIUS server to provide the user status information and user data corresponding to each user in the status table. The gateway routes the user traffic to continue the authenticated user session in response to the user data and the user status information without requiring re-authentication following the failure.

A data call between at least two internetworked computers is established using a central server and call clients in the two computers. Once the data call is in place, a video telephony conversation is initiated. In addition, still images such as a slideshow of personal photographs are shared between the two computers while the video telephony call fully continues. Image viewer subclients utilize the same network session as is used by the call clients. Either user can pause, navigate through, or change the display a parameters of the slideshow as it is being viewed by both users.

A network apparatus includes a plurality of service-option resources, each resource having a respective numerical network address. An address server stores the numerical network addresses together with a respective logical name corresponding to each numerical network address. The address server responds to queries by providing a numerical network address corresponding to a logical name contained in a respective query. A plurality of service selection gateways are coupled to the service-option resources and the address server. Each service selection gateway 1) receives user traffic from a respective user directed to a nominal destination, 2) determines if the nominal destination should be redirected to a respective logical name corresponding to one of the service-option resources in response to a respective user profile, and 3) queries the address server for a respective numerical network address to redirect according to the respective logical name.

A centralized gateway connects to a broadband digital network for receiving various types of video feeds. The gateway provides output television signals directly to conventional inputs of standard television receivers. Port extenders connected to the gateway via a local-area network allow users to select a video feed sent by the gateway to a television associated with each port extender. The port extenders each provide a convenient and low cost termination point for keyboards, mice, joysticks, digital cameras, and other peripheral devices to interact with computer-based network services via the centralized gateway. The capabilities of the port extenders and the gateway provide a substitute for a personal computer in basic Internet access activities as well as a lower cost system for providing network based video programming to multiple televisions.

A data call between at least two internetworked computers is established using a central server. Once the data call is in place, prerecorded motion video is shared between the two computers by creating a streaming video server on one user's computer for streaming the prerecorded motion video simultaneously to both users as clients of the streaming server. Either user can pause, rewind, or fast forward the streamed video as it is viewed by both users.

A data call between at least two internetworked computers is established using a central server. Once the data call is in place, any types of data, information, or computer resources are shared between the two computers, regardless of protocol or data format, by creating a virtual server on one user's computer for serving the shared information simultaneously to both users as clients of the virtual server.
