1 What is SDN and What it is not, 2 Recent Trends in Networking. 3 Software Defined Inter Cloud, 4 Inter Cloud Use Cases. Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. What SDN is Not, SDN OpenFlow SDN Standard SDN Centralization. Southbound API of control plane, SDN Separation of. Control and, Data Planes, All of these are mechanisms.
SDN is not about a mechanism, It is a framework Many solutions. Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. Three Features that Define SDN, 1 Abstract the Hardware No dependence on physical. infrastructure Software API, 2 Programmable Shift away from static manual operation to. fully configurable and dynamic, 3 Centralized Control of Policies. Policy delegation and management, Policies Controller.
Network Policies, Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. Software Defined Anything SDx, Tsunami of software defined things. Software Defined Networking SDN, Software Defined Datacenter SDDC. Software Defined Storage SDS, Software Defined Compute SDC. Software Defined Infrastructure SDI, Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain.
Ten Benefits of SDN, 1 Programmability Can change behavior on the fly. 2 Automation, 3 Orchestration Manage thousands of devices. 4 Visibility Centralized monitoring of state, 5 Performance Optimize network device utilization. 6 Virtualization Use resources without, worrying about location size etc. 7 Dynamic Scaling Can change size quantity, 8 Multi tenancy.
9 Service Integration, 10 Openness Full choice of Modular plug ins 6. Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. Centralized vs Distributed, Fast Response to changes Time to converge. Fast Consistency Slow consistency, Less overhead Scalable Not scalable. Single Point of Failure Fault Tolerant 7, Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. Four Confusions About SDN, 1 Policies vs Control, Control All bits and messages not sent by the user.
In IP control includes all headers and all routing messages. 2 Separation of Control Plane, Elements have only data plane and have no brains. 3 SDN vs OpenFlow, OpenFlow is the father of SDN but not SDN. 4 Need OpenFlow OpenFlow is micro management, It is not scalable. For large infrastructure need scalable solutions, Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. Separation vs Centralization, Separation of Centralization of.
Control Plane Policies, Micromanagement is not scalable 9. Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. How to SDN, ONF Industry, Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. Current SDN Debate What vs How, 1 SDN is easy if control is centralized but not necessary. Distributed hierarchical solutions may be required for. fail safe operation, 2 Complete removal of control plane may be harmful. Exact division of control plane between centralized. controller and distributed forwarders is yet to be worked. Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain. Current SDN Debate What vs How Cont, 3 SDN is easy with a standard southbound protocol like.
OpenFlow but one protocol may not work scale in all. 1 Diversity of protocols is a fact of life, 2 There are no standard operating systems processors. routers or Ethernet switches, 4 If industry finds an easier way to solve the same problems. by another method that method may win E g ATM vs, Washington University in St Louis http www cse wustl edu jain talks sdn mlc htm 2015 Raj Jain.
