摘要： In a computer network having a plurality of nodes with one or more computer systems associated with a node a method for transmitting messages to and from a DOS application resident in a memory to and from the network. The messages to and from the DOS application are handled a virtual device driver resident in the memory which is monitoring the 5C interrupt. The virtual device driver converts an outgoing CCB1 message from the DOS application to a message in a CCB3 32-bit format and an incoming 32-bit CCB3 message to a CCB1 format. The virtual device driver transmits the CCB3 message to a physical device driver resident in system memory. The physical device converts messages between the CCB3 32-bit format and a CCB3 16-bit format. The physical device driver transmits and receives 16-bit CCB3 messages to and from a logical link control protocol driver resident in the memory. The logical link control protocol driver is preferably written to the ISO 8802-2 standards and passes and receives messages to and from the MAC layer and the LAN adapter. With an incoming message the virtual device driver arms a context hook which fires when the operating system has allocated sufficient memory to the DOS application resident Virtual 86 mode before transmitting the CCB1 message to the DOS application.

摘要： A network controller system including a plurality of network ports and a driver system that operates the network ports as a team. The team is operated to simulate a single logical device in one of several team modes, such as fault tolerance or load balancing modes, to enhance performance of communication of the computer in a network. The driver system periodically determines and updates the status of each of the network ports, where the status of each is based at least on whether at least one directed packet has been received and transferred to the driver system by a respective network port. If any one of the network ports has not received a directed packet within a predetermined time period, the driver system commands another network port to transmit a directed heartbeat packet to the network port that has not received a directed packet. The team may include a primary and one or more secondary ports. The primary port sends a directed packet to any secondary port that has not received a directed packet within the predetermined time period. One or more of the secondary ports may each send a directed heartbeat packet to the primary port if the primary port has not received a directed packet within the predetermined time period.

摘要： A network controller system including multiple network ports and a driver system that programs each of the network ports with a common multicast address and that operates the network ports as a team. The team is operated to form a virtual device in one of several team modes, such as fault tolerance or load balancing, to enhance performance of communication of the computer in a network. The driver system commands at least one of the network ports to transmit a multicast heartbeat packet, where each of the other network ports receives and transfers the multicast heartbeat packet to the driver system. In this manner, the driver system need only send one multicast heartbeat packet to test all of the other network ports. Two network ports are selected to each send a heartbeat packet to test each other heartbeat port and the remaining ports. Multicast heartbeat packets are substantially more efficient than broadcast heartbeat packets, since the number of packets transmitted on a network is substantially reduced and the amount of unnecessary processing per heartbeat packet is reduced or even eliminated.

摘要： A network controller system comprising a plurality of network ports and a driver system that operates the plurality of network ports. The driver system determines which of the network ports can be combined together to form a team. Each network port in the team is associated with a different network interface card (NIC). The NICs are associated with a common network address to be used by external network logic.

摘要： A portable device includes a location detector, a time detector, and an alarm module to generate alarms based on both time-based and location-based criteria. A current time provided by the time detector is compared to a time-based criterion, and a current geographical location provided by the location detector (e.g., global positioning system or GPS receiver) is compared to a location-based criterion to determine whether or not to generate an alarm.

摘要： A port-centric controller system for a computer including a plurality of network ports implemented with a plurality of network controllers and a driver system capable of operating each of the network ports in either a stand-alone mode or a team mode and that monitors the status of each of the network ports. The controller system further includes configuration logic that interfaces the driver system to display port-specific graphic representations of the configuration and status of each of the plurality of network ports. The graphic representations preferably distinguish between each of the plurality of network controllers and each of the plurality of network ports. The driver system monitors the link status of each of the network ports indicative of cable status, and the graphic representations include a corresponding cable fault icon indicative of a cable fault at a network port. The graphic representations may include separate icons for a powered off status, a hardware failure status, a cable fault status, a powered off when cable faulted status, a hardware failure when powered off status and an uninstalled controller. The graphic representations may further include an icon representing each network port in a team of network ports and an icon representing a non-active network port in the team. The graphic representations may further include team, controller, slot and bus information.
