3. Why do we need a new Architecture?
Current Internet is very successful as a communications system
However, we have been attempting to put support for mobility, QoS and security on top of it
This is failing
Better approach:
Need to build communications, mobility, QoS and security into a new architecture

7. What about other architectures?
Hokey
Secure handovers in heterogeneous networks
Ambient Networks
Seamless connectivity
Mobile Ethernet
Adopted a two-framework approach as in Y-Comm but kept an Ethernet-Type Core
Verdict: Y-Comm is more flexible and offers more functionality

8. Can Y-Comm map to existing Mobile Networks?

9. So why do something new?
SDN and NFV offers us a new and more flexible way of doing things
The Future Internet will have to support a large number of diverse networks
Not just mobiles
Vehicular networks; Home Networking, etc
Allows us to combine new technologies into a new framework

11. Way Forward: Build Core-Endpoints using SDN and NFV

12. What do we need to do?
Top: move most of the functions for end-to-end communications into applications in the Cloud (the Brain)
They interact using RPC via data model language
Bottom: Interface OpenFlow to IEEE
OpenFlow will have an understanding of radio channels not just a flow on a data-switch (New Body)
Centre: A New Protocol to connect top and bottom (NMCP)

15. Network Management Control Protocol (NMCP) – Key entities
An endpoint is a device that can send or receive data; e.g. mobile phone, server, router
A link is a connection between two endpoints
A path is made up of one or more links
A dataflow is the data flowing along a path
A connection is a dataflow moving along a path

16. NMCP -- Commands Link Commands Path Commands Dataflow commands
Create, remove, activate and deactivate links
Path Commands
Create, modify and delete paths
Dataflow commands
Create, modify, delete, merge, demerge
Parameter commands
Set and get parameters
Event notification commands
Set and delete event notifications

19. Current Work
Writing modules that run on an SDN controller that can map links in NMCP to Flows on a SDN data-switch
Called the Link Mapper
Using an ODL controller
Endpoints use MAC addresses
Some NMCP routines can run as modules directly on controllers
e.g. network topology manager; events and triggers manager
Other high level routines run as applications using Cloud/NFV
