Dynamic Bandwidth Algorithm of TWDM PON for Power Saving

전력 절감형 TWDM PON의 동적대역할당 방법

  • Published : 2014.05.28


This paper proposes a new dynamic wavelength and bandwidth allocation algorithm for TWDM PON (time and wavelength division multiplexed passive optical network) which consists of an OLT (optical line termination) and multiple ONU (optical network unit). The proposed algorithm dynamically limits the number of the upstream wavelengths based on the request amount of ONUs to save power.
