5. The Service Trend NaaS
"Decoupling infrastructure management from service
management can lead to innovation, new business models,
and a reduction in the complexity of running services. It is
happening in the world of computing, and is poised to
happen in networking."
Jennifer Rexford, Eric Keller

6. Outline
● NaaS
● NaaS & Cloud
○ Cloud Limitations
○ Customer Interests
○ Other Possibilities
● NaaS Solutions
● The Future of NaaS
*

7. Cloud Limitations NaaS & Cloud
*

8. Cloud Limitations NaaS & Cloud
Limited visibility of network resources
○ No network monitoring
○ No multicast services
○ No custom path selection
Limited Security
○ No VPN establishment
○ Limited Network policies
○ Lack middlebox interposition
*

9. Customer Interests NaaS & Cloud
● Configure specific network policies
● Access to Data Plane
● Implement in-network services
● Performance
*

10. Other Possibilities NaaS & Cloud
Distinct network services can be provided by
○ Cloud-providers
○ Third-party providers
○ Research approaches
○ Network Virtualization (Overlay Networks etc.)
But a central efficient framework does not
exist.

11. Outline
● NaaS
● NaaS & Cloud
● NaaS Solutions
○ The Single Router
○ NaaS Boxes
○ CloudNaaS
● The Future of NaaS
*

12. The Single Router NaaS Solutions
"Basic Connectivity is Not Enough"
Goal: Provide in-network functionality for
● Customer controlled routing
● Cloud computing
● Gaming and Live video streaming
● Network Monitoring
*

13. The Single Router NaaS Solutions
What it provides?
○ Interactive Program (API)
○ Routing Policies
○ Access to Data Plane
○ General-purpose processing
*

14. The Single Router NaaS Solutions
*

15. The Single Router NaaS Solutions
Challenge:
Infrastructure is distributed
Solutions:
○ Choose a placement
○ Configure inter-processor communication
○ "Tune" the switch
○ Dynamic Adaptation
*

16. The Single Router NaaS Solutions
Challenge:
Infrastructure is shared
Solutions:
○ Single control process handling all customer's routing
sessions
○ tag with customer ID and and process each using
the particular customers policy
*

17. The Single Router NaaS Solutions
Benefits
● Automate configuration
● Manage separate services independently
● Simplify management
● Outsourced IT
*

18. NaaS Boxes NaaS Solutions
Goal: Enable cloud users to
● deploy custom routing protocols
● deploy custom multicast protocols
● modify packets' content on path
*

19. NaaS Boxes NaaS Solutions
*

20. NaaS Boxes NaaS Solutions
Functionality
● Network Visibility
● Custom Forwarding
● In-network Processing
Requirements
● Integration with current DC hardware
● High-level Programming Model
● Scalability and isolation
*

21. NaaS Boxes NaaS Solutions
*

22. NaaS Boxes NaaS Solutions
Benefits
● Fine grained control over small fraction of
applications:
○ Improve overall network efficiency
○ Improve performance for individual
customer
● Considers limited processing capabilities of network
components
*

23. CloudNaaS NaaS Solutions
SDN + Indirection + Host-Based
vSwitches
Goal: Deploy extensible set of network functions such as
● fine-grained network isolation
● custom addressing
● flexible interposition of various middleboxes
● optimizations for performance and availability
*

24. CloudNaaS NaaS Solutions
*

25. CloudNaaS NaaS Solutions
Cloud Controller
● Specify user requirements
● Convert rules into communication matrix
● Modified OpenNebula
*

26. CloudNaaS NaaS Solutions
Network Controller
● Compile matrix entries into network-level rules
● Install rules and configure paths
●
*

27. CloudNaaS NaaS Solutions
*

28. CloudNaaS NaaS Solutions
Benefits
● Allows network functions for production
enterprise applications in IaaS clouds
● Optimized for use in cloud
● Supported by experiments and simulations
● Innovative networking technology and
standards
● Existing prototype
*

29. Outline
● NaaS
● NaaS & Cloud
● NaaS Solutions
● The Future of NaaS
*

30. Future of NaaS
Opportunities:
● New business model
● New research horizons regarding NaaS:
○ Scalability, Performance, Isolation,
Programmability
○ pricing model
○ WAN extension
*

31. Conclusion
Network as a Service
● Provide to the users access to network infrastructure
● Must have: High level API, Security, Scalability
● Issues: Performance, Isolation, Programmability
● Different approaches proposed - still open research area
● NaaS can lead to new business models
