Abstract: Methods, apparatus, and computer program products are disclosed for optimizing communications throughput in a wireless networking environment that supports a plurality of communications channel topologies that include identifying a plurality of clients having wireless network adapters supporting disparate channel bandwidths in the wireless networking environment, and periodically switching from one communications channel topology to another communications channel topology in dependence upon the supported channel bandwidths of the adapters of the identified clients.

Abstract: This present invention relates to a method for using hypervisors to enable stable wireless network connections. The crux of the invention involves pushing the control of the networking devices from the Operating System level down to a networking front end hypervisor level. The hypervisor will control all networking devices, the authentication for these devices, and the selection of which connection to use. The hypervisor will also perform Network Address Translation (NAT) to the Operating System. Thus, the Operating System will receive a single, private IP address for use with the Operating System's applications. The hypervisor will handle the change of the IP address when roaming between networks and hide it from the Operating System through the use of the NAT.

Abstract: A system, method, and program product is provided that communicates virus information between a computer that detects a virus in a file (the detecting computer system) and the computer that sent the infected file (the infected computer system). When the infected computer system sends an infected file to the detecting computer system the detecting computer system detects the virus in the infected file, retrieves virus information corresponding to the virus (such as the name of the infected file, the identifier, or name, of the virus, the virus definitions used to identify the virus, and any instructions needed to eradicate the virus), and automatically sends the virus information back to the infected computer system over the network.

Abstract: An arrangement facilitating the connection of a client to a network through an access point, particularly in an area with overlapping 0.11n channels. Preferably, a client may communicate with two access points and “ask” one of them to stop transmitting long enough so as to facilitate communication with the other access point. Current specifications otherwise provide no workable arrangement for handling overlapping channels.
