  2. It is avoiding to be engrossed bandwidth by useless fi 11ing data that is transformed in network. in order to assure the rea1 tiine of network transport, network is maintained a 1 ight - - 1oad status. it 1s the ways that fie1dbus is powered providing work - - power for fie1d device by spare wires among 1 inking - - wires

    我們用全雙工交換式以太網技術解決傳輸中通信的實時性和確定性問題,便用交換式集線器擴大網路帶寬,使用udp通信協議保證報文傳輸的有效載荷、避免不必要的填充域數據在網路上傳輸所佔用的帶寬,使網路保持在輕負荷工作條件下,進一步保證網路傳輸的實時性。
  3. Efm use ordinary ethernet frame to transport oam information but special destination address and type code field, considering epon protocols were standarded last year, most of the network device may not recognize the oam frame above data link layer, so we use linux access link layer method to construct / capture oam frame at l2
