摘要： A computer system comprises host processor and a network interface, wherein the host processor includes resources supporting a full power mode, a lower power mode and a power down mode, as seen in standard system bus specifications such as PCI and InfiniBand. The network interface includes a medium interface unit coupled to network media supporting a least high speed protocol, such as a Gigabit Ethernet or high-speed InfiniBand, and a lower speed protocol, such as one of 10 Mb and 100 Mb Ethernet or a lower speed InfiniBand. Power management circuitry forces the medium interface unit to the lower speed protocol in response to an event signaling entry of the lower power mode. In the lower power mode, the network interface consumes less than the specified power when executing the lower speed protocol, and consumes greater than the specified power when executing the high speed protocol. Logic in the network interface operates in the lower power mode, and uses the lower speed protocol to detect a pattern in incoming packets. In response to the detection of said pattern, the logic issues a reset signal to the host processor. Thus, the network interface operates as a wake-up device in the lower power mode, using the lower speed protocol.

摘要： A system which provides for generation of alert packets using network interfaces. The alert packets are downloaded into a network interface, for example during a transition from an OS-present state to an OS-absent state. The alert packets are provided with control fields which, in various combinations, indicate alert conditions upon which such packets are to be transmitted, and which indicate a repetition mode for transmission of the packet after a match of the alert condition. Logic in the network interface, causes scanning in the plurality of packets downloaded into the network interface at scan intervals to identify packets having control codes matching alert signals received by the network interface. The process allows for more than one alert packet to be matched with a single alert signal during a given scan interval, and to be transmitted. Also, in one embodiment, each alert packet which matches an alert signal can be transmitted according to a repetition mode indicated in the control fields of the packet.

摘要： A network interface comprises the first port on which incoming data is transmitted and received at the data transfer rate of the network, a buffer memory coupled to the first port, and a second port coupled with the buffer memory, and through which transfer of packets between the host system, and the buffer memory is executed. A driver in the host system allocates a plurality of sets of receive buffers, where each set of receive buffers is composed of receive buffers having different sizes. A receive buffer descriptor cache located at the interface level stores receive buffer descriptors corresponding to receive buffers in the plurality of sets. As incoming packets arrive at the interface, logic determines the size of the incoming packet and assigns the packet to a receive buffer descriptor in the receive buffer descriptor cache according to the determined size. Upload logic at the interface level manages the uploading of packets from the buffer memory to the host system using the assigned receive buffer descriptors. A driver in the host dynamically adjusts the sizes of receive buffers in response to statistics about packet size.
