FOREWORD
According to the ITU-T Recommendation G.709,an Optical
Transport Network (OTN) is composed of a set of optical
network elements connected by optical fiber links. The network
provides functionality of transport, multiplexing, routing,
management, supervision, and survivability of optical channels
carrying client signals.
This architecture can be seen as a combination of the
advantages of SDH/SONET technology with the flexibility of
DWDM. Using OTN, the OAM&P functionality of SDH/SONET is
applied to DWDM optical networks.
Compared to SDH/SONET, OTN has the following advantages:
•Stronger error correction mechanisms
•More levels of tandem connection monitoring
•Transparent transport of client signals
•Switching scalabilityIntroduction
