Network Technology (II)

• Due to current internet rage, everything with the name "ethernet" will quickly become a commodity.

• Alternative technologies generally are much more expensive, but may be useful in certain cases (e.g. when low latency is needed):

  • FDDI (100 Mbps), obsoleted by Fast Ethernet.
  • SCI (Scalable Coherent Interface), low latency (< 10ms) but requires special coherency support in case of shared memory.
  • Myrinet, 640MB/s - 2.4GB/s, expensive, single vendor.
  • ATM, not appropriate as node interconnect.
