    IEEE 802.3bz, NBASE-T and MGBASE-T are standards released in 2016 for Ethernet over twisted pair at speeds of 2.5 and 5 Gbit/s.These use the same cabling as the ubiquitous Gigabit Ethernet, yet offer higher speeds.

  4. Port Aggregation Protocol - Wikipedia

    en.wikipedia.org/wiki/Port_Aggregation_Protocol

    With Port Aggregation Protocol "the line speed of an agport is the total of the line speeds of each of its physical ports." [2] This does not automatically mean that a single transfer will use all of the aggregated interfaces bandwidth; rather, this depend on the distribution method of choice. Most Cisco switches use src/dst MAC address hash as ...

    E.W. Kettering's 1951 ASME presentation goes into detail about the development of the modern Unit injector. [6] Also Cummins PT (pressure-time) is a form of unit injection where the fuel injectors are on a common rail fed by a low-pressure pump and the injectors are actuated by a third lobe on the camshaft.

    Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.
