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”

 Processor Vendors : Freescale, Intel
 Embrace All Switching Silicon Vendors (Broadcom and Intel to be Mellanox)
 Provide legacy network equipment applications and even SDN applications
“L2, L3 and openflow 1.x protocols”
 N2OS meets Open H/W and Vendor Private H/W System
