Abstract: The present invention is directed towards the use of the masked palm civet Paguma larvata (“civet”) as an animal model system for SARS, and is based on the novel demonstration of the present invention that civets may be infected with exogenous coronavirus, and that such infection produces SARS-like symptoms in these infected animals. The present invention is directed to a civet model system for the study of the infection, replication, and clinical effects of exogenously introduced human SARS-CoV coronavirus strains, civet SARS-CoV-like coronavirus strains, or variants or derivatives thereof, and to the development of vaccines (or other methods of prevention) or treatment of infection or transmission to other civets or humans of these human SARS-CoV coronavirus strains, civet SARS-CoV-like coronavirus strains, or variants or derivatives thereof.

Abstract: The present invention supports mobility for a mobile node between different packet data services. In one embodiment, the invention includes listening for a registration message from a mobile node at an external interface of a gateway node of a wireless packet service, the registration message containing a care-of address for the mobile node that is outside of the wireless packet service, accepting a registration message from the mobile node at the external interface, and registering the mobile node to the care-of address contained in the registration message. This embodiment further includes sending a registration reply message to the mobile node via the care-of address, the registration reply message indicating successful registration, creating a binding for the mobile node, tunneling packets addressed to the mobile node to the care-of address, and receiving tunneled packets from the mobile node, decapsulating the tunneled packets and sending them to the appropriate address.

Abstract: A device is disclosed. The device includes a virtual private network (VPN) to automatically retrieve user VPN credentials and to automatically establish a VPN using the credentials whenever a network connection is established to a network access point.

Abstract: A multicarrier receiver changes receive capabilities based on a current channel utilization. The number of antennas used to receive multicarrier communication signals may be changed or the channel bandwidth may be changed.

Abstract: Transmitting Transmission Control Protocol (TCP) packets includes transmitting packets over a network path from a source to a destination using TCP in which receipt of at least some of the packets from the source at a destination is acknowledged by the destination to the source, the transmitting including a retransmission of the packets within a subpath of the network path, and managing acknowledgments of the retransmission of the packets within the subpath by a mechanism that is independent of the acknowledging by the source to the destination with respect to the transmitting of the packets over the network path.

Abstract: Techniques and structures are disclosed for providing service related information to wireless users within a wireless network.

Abstract: Systems and methods provide for controlling contention in a wireless network device. The systems and methods transmit a packet on a wireless network. If the transmission is not successful, then a contention window parameter is adjusted according to a fast backoff operation. If the packet transmission was successful and the current value of the contention window parameter is less than a threshold value then the contention window parameter is decreased according to a contention avoidance operation. If the packet transmission is successful and the current value of the contention window parameter is greater than the threshold value then the contention window parameter is decreased according to a slow start operation.

Abstract: The present disclosure relates to determining and establishing at least two node disjoint paths, and, more specifically, to determining and establishing at least two node disjoint paths within a wireless ad-hoc network that includes a source and a target node using on-demand flooding.

Abstract: Network devices on mobile networks may be configured to improve and optimize packet processing and routing. Specifically, a home agent device may be decomposed into its major functionality, namely processing and routing. Various processors on the device are assigned to specific tasks and each processor may be optimized for its specific tasks, thus improving packet processing and routing. The home agent device may comprise one or more physical components.

Abstract: Systems and methods provide a secure network path through an inner and outer firewall pair between a mobile node on a foreign network and a corresponding node on a home network. One aspect of the systems and methods includes providing a mobile IP proxy between the mobile node and a VPN gateway inside the firewalls. The mobile IP proxy acts as a surrogate home agent to the mobile node, and acts as a surrogate mobile node to a home agent residing on the home network.

Abstract: A method for correctly routing packets is described. The method includes receiving an encapsulated packet from a sending mobile node destined for a receiving mobile node. The method determines whether the encapsulated packet is from a mobile node with the recipient as its home agent (reverse tunneled packet), whether the inner packet is destined to a mobile node with the recipient as its foreign agent, and whether the packet had been received in a previous reception. If the answers for all the three are yes, the packet is then delivered to the receiving mobile node. If the answers are yes only for the first two questions, the packet is routed and transmitted away normally and a copy of the packet IP header is cached locally. For all other cases, the packet is routed and transmitted away normally.

Abstract: A method for allowing next generation mobile nodes to continue utilizing next generation mobility services when they roam into previous generation domains and communicate across previous generation networks with the next generation networks. The mobile node discovers previous generation mobile agents, obtains a previous generation care-of address for the mobile node from the mobile agents, registers with the previous generation home agent and optionally obtain a previous generation home address, creates an intergeneration pseudo interface and uses it to transmit all the signaling and data packets between a mobile node and its next generation home agent.

Abstract: The invention is to allow a mobile node to discover an agent in a network address translation (NAT) domain without requiring deploying foreign agents at each subnet or broadcasting in the domain.

Abstract: A network includes a TCP-in-TCP tunnel between a mobile device, which includes a TCP client and a gateway, and a TCP server, which resides in a subnet. Another gateway in the subnet receives and caches TCP packets and acknowledgments (ACKs) from the TCP-in-TCP tunnel. In response to receiving an indication from the TCP server that it has not received a cached TCP packet, the second gateway may resend the packet without relaying the indication to the TCP client, and the first gateway may send a control message instead of a complete TCP packet to the second gateway.

Abstract: Maintaining a reliable link includes altering a record of information transmitted across a network from a mobile unit to a destination based on an acknowledgment by the destination of receipt of the transmitted information and transmitting information from the mobile unit to the destination based on the record after the mobile unit establishes a new interface connection to the destination.
