Easyly distorted 2.some scenarios cannot be conducted 12/29/2018Doc ID 7 Literature review S.n . Title Aim Gap 12/29/2018Doc ID 8 Objective ¶ Because of the above two problems ¶ This paper develop ¶ New SDN Research L aboratory b ased on professional core networking platforms ¶ New software defined approach's ,algorithms ,protocols and ¶ Optimizing existing one 12/29/2018Doc ID 9 Methodology 1.

Using SDN Testbed Solution 2. Propose two experimental environments for SDN Studies 1.Data Center Networks 2.Wide Area Networks(WAN ) ¶ Conditions of real Data center and wide area network exactly shown 12/29/2018Doc ID 10 SDN Testbed Solution ¶ Innovations in SDN architecture validated using A. Emulations and Simulations Tools B. Software Switches C. Net -FPGA 12/29/2018Doc ID 11 Continued A. Emulations and Simulations Tools ¶ Enable fast prototyping,deployement, and testing ¶ No need expensive physical device ¶ Example mininet Mininet : ¶ Allows an entire OpenFlow network ¶ C ontains 100s of nodes and 10s of switches ¶ Emulated on single machine and use virtualization 12/29/2018Doc ID 12 Continued B. Software Switches ¶ Used to validate simulation result ¶ Used can be as Part of virtualized environment Mixed environment built with both hardware and sw or Installed on physical Linux machine Devices built on Raspberry pi embedded machines 12/29/2018Doc ID 13 Continued C. Net -FPGA ¶ Platform for building high performance networking system in hardware ¶ Packet processed at line -rate in a way program by user ¶ Consist of PCI based board ¶ Support three platforms with different performance 12/29/2018Doc ID 14 Continued 1.NetFPGA SUME ,platform with 100Gbps I/O capabilities 2.NetFPGA -10G ,a platform with multiple 10Gbps interfaces 3.NetFPGA -1G ,a recent platform designed for low - bandwidth applications 12/29/2018Doc ID 15 SDN Research Environment ¶ SDM research laboratory made up of SDN -ready routers and switches SDN controller(server with appropriate sw ) Hardware equipment for :Traffic generation and :M easurement of network efficiency and QOS 12/29/2018Doc ID 16 Result ¶ Develop new SDN laboratory Based on professional core networking platforms ¶ This networking platforms are SDN -ready switches, SDN -ready Routers, Network Servers, Hardware Network Analyzer and Traffic generator 12/29/2018Doc ID 17 Continued ¶ Develop new software defined approach's That is SDN networking paradigm In which intelligence is moved from routers and switches to sw or network operating system . Introduction of new protocols, techniques and emerging services is easily implemented ¶ Faster Adaption of new version of excising protocols and algorithm. ¶ High flexibility and agility is reached in network ¶ ,algorithm ,protocols and 12/29/2018Doc ID 18 Continued ¶ High cost reduction for physical device by providing virtualization platform ¶ The SDN research laboratory can support experiment on all scenario ¶ Scenario: migration b/n datacenters, data flow b/n users, disaster recover etc. and ¶ Allows for conducting wide range of studies and experiments in the area of SDN ¶ The result easily implemented on real world environments. 12/29/2018Doc ID 19 L imitations ¶ The research in laboratory only explore two environments (Data center networks and WAN) ¶ Professional core networking platforms (switches, routers, server and traffic generator ) are only one vendor brand that is used to develop the two topologies ¶ The paper doesn't suggest future research areas 12/29/2018Doc ID 20 Conclusion ¶ The concept of new Software Defining Networking laboratory was presented ¶ Two experimental topologies developed ¶ For conducting experiments and developing new solutions which can be implemented in real production environment 12/29/2018Doc ID 21 Question & Answer 12/29/2018Doc ID 22 12/29/2018
