An approach to an IP over WDM transmission network modelling

The paper describes an approach to the optical transmission network modeling. The modeling process is based on two main assumptions -transmission network carries IP datagrams using the layer 2 protocol as a framing technique and wavelength division multiplexing (WDM) is used as a transmission technique on the physical layer. Protection and restoration mechanisms have been implemented on the photonic layer and QoS is supported by the Internet protocol. An IP over WDM network structure has been presented, along with the description of the optical component modeling process.
