초고속 인터넷 서비스가 보급된 이후 가입자들은 점점더 많은 서비스를 요구하게 되고, 이에 따라 더 많은 대역폭을 필요로 하게 되었다. 저렴한 비용으로 사용자들의 요구 사항을 충족시킬 수 있는 방안으로 E-PON(Ethernet-Passive Optical Network) 기반의 광가입자망에 대한 관심이 증가하고 있다. 이에 본 논문에서는 E-PON 기반 광가입자망의 핵심적인 구성 요소인 eOLT(enhanced Optical Line Termination) 시스템에서의 VLAN(Virtual Local Area Network) 서비스 요구 사항 및 제공 구조를 제시 하고자 한다.
