Dynamic Reconfiguration Policies for Reconfigurable Coded-WDM PONs

摘要

This paper studies the issues arising when reconfiguring coded-WDM networks to provide protection against eavesdropping and it proposes a tradeoffs involved in carrying out this reconfiguration process. It commences by showing that the degree of confidentiality (DOC) and the traffic loss are two important, but conflicting, objectives in the design of reconfiguration policies. The reconfiguration problem is formulated as a Markovian decision process (MDP). The results obtained from MDP theory are applied to establish optimal reconfiguration policies for coded-WDM networks with various system parameters.
