Published on

Software-defined networking (SDN) is an emerging set of technologies within network management that promises to solve many of the limitations imposed by current networking technology on rapidly evolving cloud-computing technologies. The SDN usage model specifies actions and processes to advance development of practical solutions that seek to lower management complexity and costs, especially in heterogeneous, multi-vendor environments. This presentation gives an overview of the usage model requirements and usage scenarios.

ODCA Software Defined Networking Master Usage Model

  1. 1. SOFTWARE DEFINED NETWORKING Chris Swan CohesiveFT
  2. 2. AGENDA TOPIC UM CORE LEARNING Software Defined Networking: ODCA Usage Model – published June 2013 SDN-Enabled Network Services Layer 2 Multi-Path Layer 2 Network Bridging Considerations and take-aways from this UM ODCA Flash Seminar | 2
  3. 3. SDN UM BACKGROUND Most Infrastructure as a Service (IaaS) consists of Compute, Storage and Network. Having addressed Compute in the CIaaS master usage model published in 2012 the Infrastructure working group turned to Scale out Storage and Software Defined Networking in 2013. The SDN UM addresses and identifies: 1. 2. 3. 4. 5. 6. What is SDN, and why is it beneficial Usage scenarios Lifecycle model Usage requirements RFP requirements (PEAT integration) Required industry actions ODCA Flash Seminar | 3
  4. 4. UM CORE – KEY ELEMENTS Challenges of Modern Networks Security, Logical grouping, Access control, QoS, Flow control Requirements of Modern Networks Adaptability, Automation, Maintainability, Model management, Mobility, Integrated security, On-demand scaling Concepts of Software Defined Networking Separation of the network layers Centralized management Standardized protocols The Four Layers of Network Software Forwarding plane Control plane Services plane Management plane ODCA Flash Seminar | 4
  5. 5. SDN CONCEPTUAL ARCHITECTURE ODCA Flash Seminar | 5
  6. 6. UM CORE – KEY ELEMENTS CONT. Benefits of SDN Challenge of Security within an SDN environment Centralized network control and programmability Dynamic network segmentation VMs visibility Capacity utilization Network capacity optimization Distributed application load balancing Distributed network security services Dematerialization More dynamic change Need to integrate with audit/monitoring/logging ODCA Flash Seminar | 6
  7. 7. USAGE SCENARIOS Usage Scenario 1 SDN-Enabled Network Services Usage Scenario 2 Enable Layer 2 Multi-Path (East-West) Traffic Usage Scenario 3 Enable Data Center L2 Network Bridging ODCA Flash Seminar | 7
  8. 8. ENABLE LAYER 2 MULTI-PATH (EAST-WEST) TRAFFIC ODCA Flash Seminar | 8
  9. 9. ENABLE DATA CENTER L2 NETWORK BRIDGING ODCA Flash Seminar | 9
  10. 10. KEY INDUSTRY ACTIONS (STANDARDS AND MORE) Open Network Foundation (ONF) Collaboration collaboration on Southbound interfaces focusing on (dynamic network segmentation into logical groups, multi-path traffic, layer 2 network bridging) with other groups as appropriate on other areas of SDN. e.g. Abstracted control of network capabilities, Integration of network automation into overall provisioning and orchestration (in line with CIaaS MUM) Adoption and full production implementations of SDNs in cloud environments as quickly as practical. Support for initiatives, including OpenFlow, across all cloud-provider platforms. ODCA Flash Seminar | 10
  11. 11. PROGRESS THROUGH 2013 Jun 2013 SDN UM published Aug 2013 Major SDN product launches – not much sign of OpenFlow Nov 2013 PoC at TM Forum event in partnership with ServiceMesh, Netronome & PlumGrid ODCA Flash Seminar | 11
  12. 12. COMING IN 2014 Broader scope Industry realignment Jun 2014 To include network function virtualization (NFV) With emergent platforms in the hardware and virtualization layers Target for publishing revised edition ODCA Flash Seminar | 12
  13. 13. KEY TAKE-AWAYS FROM THIS UM SDN is a key element of the software defined data center (SDDC) as a means to build IaaS APIs to the network allow for more dynamic configuration and automated provisioning This is a fast moving part of the industry, and much of what we did in H1-2013 has been overtaken by events More to come later this year ODCA Flash Seminar | 13
