N:1 fast protection in NG-PON2
2015
This paper proposes a fast N:1 protection mechanism for NG-PON2 network. When failures occur the affected ONUs conduct wavelength tuning to realize fast service recovery. We analyzed data loss from protection using a Markov chain model. The numerical results show the fast protection scheme reduces the disconnection time, and ONU configurations of logic connections and service managements are fully reserved.
