Advanced Optical Networking Training Course by TONEX


Advanced optical networking training covers transport network evolution, IP/MPLS, GMPLS, MPLS-TP, Seamless MPLS, OTN and DWDM concepts.

Multilayer network design including  IP/MPLS over OTN over DWDM are identified as promising that bridges integration and interaction between the IP and optical layers. In this course we describe and  analyze the impact of each layer’s parameter values on neighboring layers and overall network architecture, performance and cost.
