Software Defined Networking Research Group

(SDNRG)

IAB Breakfast 01 Aug 2013

David Meyer & Nick Feamster

Scope

• Classification of SDN models– Definitions– Taxonomies– Relationship to work ongoing in the IETF and other related groups

• ETSI NfV, ONF, ORNC OpenDaylight, …

• Use cases

• SDN model scalability and applicability– Structure Complexity– Other properties

• Logically centralized controller• Implications of the lost of control plane/data plane fate sharing• CAP theorem implications for “logically centralized” controllers

• Multi-layer programability and feedback control systems

• Network description languages, abstractions, interfaces and compilers– Methods and mechanisms for (on-line) verification of correct operation of network/node function.

• Security

Meetings

• IETF 84

• IETF 85

• IETF 86

• Planned: SIGCOMM

Charter

Long Story Short on the Charter

• High Level Goal: Help frame the research agenda for the SDN community– Provide a forum for discussion of SDN issues important to both the academic and

engineering communities– Bidiectional information flow– Produce relevant documents (as outlined in the charter)

• Not necessarily RFCs

• Seeking participation from/with both the academic and engineering communities

• Connect with other related groups including IETF, ETSI NFV, ONF, ONRC, SIGCOMM, Upperside, …

FP/SDNProperties:-- Complete Separation of CP and FP-- Centralized Control-- Open Interface/programmable Forwarding Plane-- Examples: OF, ForCES, various control platforms

OL/SDNProperties:-- Retains existing (simplified) Control Planes-- Programmable overlay control plane-- Examples: Various Overlay technologies

CP/SDNProperties:-- Retains existing (distributed) Control Planes-- Programmable control plane-- Examples: PCE, I2RS,BGP-LS, vendor SDKs

Physical and Virtual Resources(CSN)

Control and Orchestration (overly simplified view)

Apps Apps…

Service Layers

BTW, my view: SDN Continuum

May be repeated(stacked or recursive)

Q&A

Thanks!
