摘要： A system and method for enabling a zero configuration nomadic wireless and wired computing environment presenting a just works experience is presented. The system examines predefined user preference or profile settings to determine to which of a competing number of wireless networks available it should connect, and what type of authentication should be used for such connection. Nomadic wireless computing between infrastructure wireless networks and ad hoc wireless networks may be accomplished without further user intervention required in an auto mode. Also, both infrastructure only and ad hoc only modes are available through the system of the invention. Further, the user may set a preference for infrastructure or ad hoc modes in the auto mode. With an infrastructure mode preference set, the system will automatically detect and transfer connectivity to a newly available infrastructure wireless network if the user was previously operating off-line or in ad hoc mode.

摘要： A method and system for multicast network transmissions dynamically sets response time parameters for handling negative acknowledgments (NAKs). When the sender receives a NAK for a lost packet, it returns an NAK confirmation (NCF), waits for a back-off time before sending requested repair data, and then waits for a “linger time” during which the sender does not respond to other NAKs for the same lost packet. The back-off time and the linger time are dynamically set according to the position of the requested sequence number in the sender's transmit window such that the back-off time is shorter when the requested data is closer to being flushed out of the transmit window. After receiving the NCF, the receiver waits for a timeout period and resends the NAK if no repair data is received. The timeout period for data receipt is dynamically set according to a statistical average time for receiving repair data from the sender and the estimated sender's transmit window size.

摘要： A protocol and method for establishing wireless data sessions between wireless clients, each of which support multiple wireless protocols is presented. A commonly supported wireless protocol is utilized to share the wireless protocols supported by the clients' circuitry. A wireless data session is then established based on the common capabilities of the wireless clients. Where multiple common protocols are supported, user preferences are utilized to determine which of the commonly supported protocols will be utilized for the wireless data session. Once a data session is established, the control channel may be idled periodically to conserve power. Alternatively, the protocol utilized in the wireless data session may be used to transmit control messages using the protocol of the present invention.

摘要： The invention detects and responds to events occurring on a computer network medium. When a network media event is detected, network parameters are adjusted, if possible, to adapt to the new circumstances brought about by the event, and traffic may be rerouted if that is appropriate. High-level protocol drivers and network-aware applications are notified of the event so that they may adapt to the changed network circumstances. Sometimes, as a result of the network media event, the computer communicates with other devices on the network to discover the state of network entities, network elements, and services.

摘要： A method and computer product for automatically generating an IP network address that facilitates simplified network connection and administration for small-scale IP networks without IP address servers, such as those found in a small business or home network environment. First, a proposed IP address is generated by selecting a network identifying portion (sometimes known as an IP network prefix) while deterministically generating the host identifying portion based on information available to the IP host. For example, the IEEE 802 Ethernet address found in the network interface card may be used with a deterministic hashing function to generate the host identifying portion of the IP address. Next, the generated IP address is tested on the network to assure that no existing IP host is using that particular IP address. If the generated IP address already exists, then a new IP address is generated, otherwise, the IP host will use the generated IP address to communicate over the network. While using the generated IP address, if an IP address server subsequently becomes available, the host will conform to IP address server protocols for receiving an assigned IP address and gradually cease using the automatically generated IP address.
