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.

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/SDN Properties: -- Complete Separation of CP and FP -- Centralized Control -- Open Interface/programmable Forwarding Plane -- Examples: OF, ForCES, various control platforms OL/SDN Properties : -- Retains existing (simplified) Control Planes -- Programmable overlay control plane -- Examples: Various Overlay technologies CP/SDN Properties : -- Retains existing (distributed) Control Planes -- Programmable control plane -- Examples: PCE, I2RS,BGP-LS, vendor SDKs Physical and Virtual Resources (CSN) Physical and Virtual Resources (CSN) Control and Orchestration (overly simplified view) Apps … Service Layers BTW, my view: SDN Continuum May be repeated (stacked or recursive) 6
