Abstract: A system and method for automatically and dynamically initiating and establishing secure connections between a Server and a Client using a session control server (SCS). Both the Server and the Client are connected to an untrusted network (such as the Internet) through a Network Address Translator or Translation (NAT) router or a firewall. The SCS, independently trusted by both the Server and the Client, brokers the required connection parameters to establish a secure connection between the Server and the Client. The system and method does not require any user configuration on the Client and eliminates the need for the Server to accept explicit connection requests or packets from the Client, thereby allowing the Server firewall to always remain closed to all inbound traffic.

Abstract: In one aspect, a system capable of performing network address changes is provided. The system comprises a network interconnecting a plurality of hosts, a mobile device connected to the network, the mobile device associated with a first network address corresponding to a first network location of the mobile device on the network, a first host connected to the network, and a mobile handler capable of communicating with the mobile device and the host over the network.

Abstract: According to some aspects, a method of providing services to a first device over a network using a network switching center adapted to locate servers capable of providing the services to the first device is provided. The method comprising acts of identifying a first service to be provided to the first device, providing notification, from the network switching center to a first server, that the remote device has requested the first service, providing, by the first server, the first service to the remote device, and indicating, by the first server to the network switching center, a second service to be provided to the remote device.

Abstract: Embodiments of the present invention are directed to a method and apparatus for restricted run-time environment with dynamic user context. In one embodiment, a user interacts with the computer system through a restricted run-time environment. When the user begins using the computer system at a local machine (i.e., a client), a user context is dynamically created at the local machine. Then, a user interface is initiated in the run-time environment which is isolated from the local machine's system files. In one embodiment, the user interface and all actions resulting from interaction through the interface take place in the isolated run-time environment. In one embodiment, the isolated run-time environment contains its own set of system files that the user may need to access. In one embodiment, the local machine is running the Unix™ operating system. A user interacts with the system through an interface running from the chroot directory.
