Abstract :
This paper analyses the connection availability of a protection paradigm, termed permanent dedicated path protection (P-DPP), in WDM mesh networks. An analytical model for calculating the unavailability of P-DPP is introduced. Numerical results on COST239 European network show that the average unavailability of the network is proportional to blocking probability of the network, and fits well with the simulation results.
