  1. OmniRAN Update on SDN Use Case IEEE 802 Wireless SDN BoF 2014-01-23

  2. SDN-based OmniRAN Use CaseReference Point Mappings Terminal Core Operator A Core Operator C Core Operator B Access Abstraction R3 R4 AAA R5 Backhaul Abstraction Access 2 R1 Access Abstraction R2 Access Abstraction SDN Controller Backhaul Access 1 • Multiple Cores sharing Access Network • Access Abstraction • Data and Control plane separation • Central control R5 Internet Access 3 Access Abstraction Access Network Core Network(s) Control path Data path

  3. SDN related Gaps in IEEE 802 • Control of data forwarding plane, common to 802 technologies • Southbound interface enabling the communication between the 802 technologies and the central controller (e.g. access abstraction) • Clearly defined interfaces, SAPs and behaviors • Ability to modify data path based on arbitrary but bounded selection parameters • Packet classification mechanisms based on templates (á la OpenFlow) • End-to-end packet flow and QoS • Radio configuration mechanism for access and backhaul links • With defined metrics and reporting • Data plane management of the multiple-interface Terminal • Notion of 802 logical interface facing L3 • Generic 802 access authorization and attachment

  4. OmniRAN Considerations for SDN • Control plane • Control of interface/radio parameters • Control of MAC-specific features • Data path establishment • User authentication and authorization • Data plane • Arbitrary matching of (wireless) frame parameters • Frame forwarding

  5. Current Assumption:Specific section on SDN Abstraction Layers • One separate section in draft ToC • Define SDN Abstraction Layers • Terminal • Access • Backhaul • Common abstraction layers applicable to different 802 technologies • E.g. 802.3, 802.11, 802.15, 802.16, 802.22, • Technology dependent profiles to support specific behavior and features

  6. P802.1CF Draft ToC • Introduction and Scope • Abbreviations, Acronyms, Definitions, and Conventions • References • Identifiers • Network Reference Model • Overview • Reference Points • Access Network Control Architecture • Multiple deployment scenarios • Functional Design and Decomposition • Network Discovery and Selection • Association • Authentication and Authorization • Datapath establishment • QoSand policy control • Datapath relocation • Datapath teardown • Disassociation • Accounting • SDN Abstraction Layer • Terminal • Access • Backhaul • Annex: • Tenets (Informative)
