2. About CableLabs
R&D Consortium chartered to foster innovation in the cable industry
57 member MSOs worldwide
150+ million subscribers
Vendor-neutral R&D/lab facilities in Louisville, CO and Sunnyvale, CA
Best known for DOCSIS® specifications
Extensive research into SDN & NFV with active participation from cable operators and vendors
ETSI NFV ISG – NOC Chair
OPNFV – Founding member, Silver End-User Director

3. CableLabs involvement with SDN & NFV
Started SDN research in 2012
Former ON.Lab member
Pox/mininet/FlowVisor experimentation
MSO and vendor use case analysis
SDN showed promise, but OpenFlow didn’t look like the right protocol for access network
Began NFV research in 2013
Experimenting with ODL in August ‘13
PacketCable Multimedia plugin – COPS protocol to control legacy CMTSs
Documentation was non-existant…
…code/interfaces kept changing…
…but we still had a working demo in 6 weeks
Continuing approach with use case analysis, architecture design, and prototyping
PCMM plugin (Helium) -> enhancing in Lithium
Looking to expand ODL engagement through OPNFV
Virtual Business CPE (MEF services)
Intent networking

9. Feedback for ODL Documentation/training/process Technology
Onboarding is challenging
Documentation has room for improvement
CI/CD toolchain training and integration with our lab
AD-SAL->MD-SAL conversion
Developer transitions
Technology
SAL is a big advantage over other controllers
Support for legacy devices/protocols
Netconf/Restconf/OVSDB/TR-069 better fits for access network than OpenFlow
Strong interest in intent projects
Current intent projects largely data center focused, and need different structure for access network
Layered subscriber model
“gold/silver/bronze” tiers of service
Parent/kid devices
TV vs. Xbox vs. PC vs. tablet (etc.)
More “service” APIs – common provisioning regardless of access technology/vendor
