摘要： A rackmount server has dual-redundant hot-swappable fans for uniformly providing air flow to a plurality of CPU modules housed in the rackmount server. Air flow generated by the fans may also be provided to I/O circuitry disposed in the rackmount server. An airflow zone in which air flow is provided by the fans is separate, however, from an airflow zone in which air flow is provided to at least one power supply and/or disk drive housed in the rackmount server.

摘要： The present invention provides a per-flow dynamic buffer management scheme for a data communications device. With per-flow dynamic buffer limiting, the header information for each packet is mapped into an entry in a flow table, with a separate flow table provided for each output queue. Each flow table entry maintains a buffer count for the packets currently in the queue for each flow. On each packet enqueuing action, a dynamic buffer limit is computed for the flow and compared against the buffer count already used by the flow to make a mark, drop, or enqueue decision. A packet in a flow is dropped or marked if the buffer count is above the limit. Otherwise, the packet is enqueued and the buffer count incremented by the amount used by the newly-enqueued packet. The scheme operates independently of packet data rate and flow behavior, providing means for rapidly discriminating well-behaved flows from non-well-behaved flows in order to manage buffer allocation accordingly. Additionally, the present invention adapts to changing flow requirements by fairly sharing buffer resources among both well-behaved and non-well-behaved flows.

摘要： The invention provides a single-chip method. The method includes a memory shared among packet buffers for receiving packets, packet buffers for transmitting packets, and packet header buffers for packet forwarding lookup. Accesses to that shared memory are multiplexed and prioritized. Packet reception is performed with relatively high priority, packet transmission is performed with medium priority, and packet forwarding lookup is performed with relatively low priority. The single-chip method includes circuits for serially receiving packet header information, converting that information into a parallel format for transmission to an SRAM for lookup, and queuing input packets for later forwarding at an output port. Similarly, the single-chip method includes circuits for queuing output packets for transmission at an output port, receiving packet forwarding information from the SRAM in a parallel format, and converting packet header information from output packets into a serial format for transmission. The single-chip method also includes a region in its shared memory for a packet forwarding table, and circuits for performing forwarding lookup responsive to packet header information.

摘要： The invention provides an enhanced datagram packet switched computer network. The invention processes network datagram packets in network devices as separate flows, based on the source-destination address pair in the datagram packet. As a result, the network can control and manage each flow of datagrams in a segregated fashion. The processing steps that can be specified for each flow include traffic management, flow control, packet forwarding, access control, and other network management functions. The ability to control network traffic on a per flow basis allows for the efficient handling of a wide range and a large variety of network traffic, as is typical in large-scale computer networks, including video and multimedia traffic. The amount of buffer resources and bandwidth resources assigned to each flow can be individually controlled by network management. In the dynamic operation of the network, these resources can be varied—based on actual network traffic loading and congestion encountered. The invention also teaches an enhanced datagram packet switched computer network which can selectively control flows of datagram packets entering the network and traveling between network nodes. This new network access control method also interoperates with existing media access control protocols, such as used in the Ethernet or 802.3 local area network. An aspect of the invention is that it does not require any changes to existing network protocols or network applications.

摘要： Provided is a 10/100Base-T MAC to PHY interface requiring only two wires (pins) per port, with two additional global wires: a clock wire (pin), and a synchronization wire (pin). This reduction in the number of pins associated with each port is achieved by time-division multiplexing wherein each time-division multiplexed wire combines a plurality of definitions from the conventional 100Base-T interface specified by IEEE 802.3u (clause 22). As a result, each port has its own pair of associated time-division multiplexed wires (pins) and the addition of each port simply requires two additional wires. According to a preferred embodiment of the present invention, information normally transferred on sixteen wires in a conventional 100Base-T interface at 25 MHz is time-division multiplexed onto two wires (corresponding to two pins) that transfer data at 125 MHz, five times the speed of conventional interfaces. Importantly, this multiplexing is done on a port by port basis. Therefore, the number of pins required for a MAC to transceiver interface is two times the number of ports plus two instead of sixteen times the number of ports, and the addition of each additional port requires only two more wires (pins).
