N2OS Overview Goal

Customize Network Equipment for All (Low to High Grade) N2OS independent of Switching Silicon Vendors Reduce the costs for a new design what has grown licensing and implementation costs

Features Play On Open Source Domain (http://openn2os.etri.re.kr/index_eng.jsp) “It’s time for network equipment to embrace open source”
