What is Open Network?
• Completely switch but no any OS and App
Open Network = Whitebox = Bare-Metal

Why should I care about Open Network?
• 5 years experiences in Cisco, Juniper, etc
• Cisco and Juniper certified
• But what will happen in the short future? (who know?)
• Asian market integration:
• Concern about future career of network engineer
• Compete with other foreign network engineers ;) or lose job :(
Work as a network engineer

Is it hard to learn Open Network?
• I am normal engineer Cisco, Juniper, with basic Linux knowledge
• It is hard as imagine for first impression but it does not at all (still switching, VLAN, Trunk, S
TP, plus Routing Quagga)
• Just different way to manage by CLI or Automation (Ansible which is cool)
• It’s easy to learn as it has guidebook which is available on Internet and free OS for testing.
First Impression

Open Network Architecture
• Switch ports
• Cumulus Linux (Switchd)
• Switch driver
• Netlink
Cumulus example

10. OPEN NETWORK DAY PHNOM PENH 2016
Installation Process
• Network OS installer for whitebox switching
• Why ONIE?
• Hardware and OS choice
• How ONIE works?
• Power on whitebox switch
• Find management port and IP address
• Network connection done, ONIE looks for available NOS from USB or network – HTTP,
FTP, TFTP
• Once discover, it start installing
• After ONIE still there but will use unless want to upgrade or unstall
Open Network Install Environment (ONIE)

Installation Process
• White box switch
• DHCP server
• Web, FTP, TFTP server
• OS switch
