OpenCloud: Value-Add Cloud
Bringing Openness and Innovation to
Network and Cloud Infrastructure
What Is Your Cloud Strategy?
• Directly Take on the OTT Cloud Providers
– Great long-term goal, but they have a 10-year head start
– Risk that you are always playing catch-up
• Apply Cloud Technology to the Central Office
– Great first step, but too modest as a long-term goal
– Risk that narrow use case doesn’t pay long-term dividends
Answer  Build a Value-Added Carrier Cloud
– Treat OTT providers as commodity
– Gain near-term CAPEX/OPEX savings
Take on OTT Providers
It’s about services, not just infrastructure

What Should Be Your Cloud Strategy?
• Treat OTT Cloud Providers as Commodity
• Treat Central Office as an Extension of the Cloud
• Leverage Strategic Infrastructure to Build a ValueAdded Cloud that providers better…

Anatomy of a Service
Service Controller
Service Instances
(VMs, Devices)
Logically centralized interface
to network-wide functionality.
• Network-as-a-Service
• Compute-as-a-Service
• Content Delivery Network
Many points of implementation
distributed across the network.
• OpenFlow Switches
• Virtual Machines
• Caches
Service Composition
Service3 = Service1  Service2
Logically compose services to achieve
desired functional/security behavior

XOS – XaaS Operating System
• Defines Service as a first class object
– Service = {Slice,…} + Controller-Plugin
• Flexible control over operational parameters
– Isolation: Slice = {VM,…} + {VN,…}
• VM = Placement + Image + Resources (e.g., cores)
• VN = Topology + NetOS + Resources (e.g., bandwidth)
– Composition: VN1 | VN2 | VN3
• Programming environment for orchestration
– Specify Service Composition Policy
– Create Custom PaaS
– Monitor & Manage Service Scaling
