Zusammenfassung:In this paper, we propose hybrid protection architecture, to protect against multipoint failure in WDM-PON which component failure can potentially lead to an enormous loss of traffic. The proposed architecture is fully configured and the protection fiber can be used to transmit extra traffic under normal states, to increase the survivability and efficiency of the network. If failure is detected, normal traffic is switched to the protection path and extra traffic is preempted. Wavelength assignment and protection methods are also proposed for our protection architecture. The performance of proposed architecture is evaluated in terms of cost, channel utilization and queuing delay.
