CORD Delivers

Economies of a datacenter

Infrastructure built with a few commodity building blocks using open source software and white boxes

Agility of a cloud provider

Software platforms that enable rapid creation of new services

Large number of COs Evolved over 40-50 years 300+ Types of equipment

Huge source of CAPEX/OPEX

Telco Central Offices

• Large number of complex facilities

– AT&T alone operates 4-5k Central Offices

– Each serves 10-100k residential, enterprise & mobile customers

• Evolved piecemeal over the past 40-50 years

– Source of huge CAPEX/OPEX costs

– Difficult to introduce new services

• Especially when compared to OTT cloud providers!

CORD Takeaways

Bring datacenter economies and cloud agility

to service providers

Enable service providers to deploy CORD POD in a day!

CORD is possibly the killer app of SDN and NFV

for service providers

Scalability, High Availability & Performance

Northbound & Southbound Abstractions

Modularity

Scale-Out Design w/ Multiple ONOS Instances

Each instance is identical

One can add and remove instances seamlessly

Each instance is a master for a sub-set of switches

It works like a single system for apps and network devices
