초록

PONs (passive optical networks)은 운용비용이 저렴하고 높은 대역폭을 제공하기 때문에 가입자망에서 각광을 받고 있다. 최근에는 WDM (wavelength-division multiplexing)와 TDM (time-division multiplexing)을 결합한 TWDM PON이 가입자망에서의 새로운 해답으로 여겨지고 있다. 본 논문에서는 TWDM PON에 대한 새로운 MAC (media access control) protocol을 제안한다. 또한 TWDM PON에 대한 새로운 동적대역할당 방법을 제안하고 성능을 평가한다.

Passive optical networks (PONs) are the emerging solution for access networks since PONs provide high bandwidth and the low operation cost. In recent, the new solution in access networks is TWDM PON which is a mixture of WDM (wavelength-division multiplexing) and TDM (time-division multiplexing). This paper proposes a new MAC (media access control) protocol for TWDM PON. In addition, this paper proposes and evaluates a new dynamic bandwidth allocation method for TWDM PON.
