Hands-on Workshop on Open vSwitch and Software-defined Networking Ali AlSabeh, Jorge Crichigno University of South Carolina http://ce.sc.edu/cyberinfra aalsabeh@email.sc.edu, jcrichigno@cec.sc.edu WASTC 2021 virtual Faculty Development Weeks (vFDW) June 21, 2021 1
SDN Lab Series The labs provide learning experiences on essential SDN topics Mininet Legacy networks, Border Gateway Protocol (BGP) FRR routing, an open routing implementation MPLS networks early efforts toward SDN SDN fundamentals controllers, switches ONOS controller Open Virtual Switch (OVS) Traffic isolation with VXLAN OpenFlow Interconnection between SDN and legacy Networks, etc. 3
SDN Lab Series Lab experiments Lab 1: Introduction to Mininet Lab 2: Legacy Networks: BGP Example as a Distributed System and Autonomous Forwarding Decisions Lab 3: Early efforts of SDN: MPLS example of a control plane that establishes semi-static forwarding paths Lab 4: Introduction to SDN Lab 5: Configuring VXLAN to Provide Network Traffic Isolation Lab 6: Introduction to OpenFlow Lab 7: Routing within an SDN network Lab 8: Interconnection between legacy networks and SDN networks Lab 9: Configuring Virtual Private LAN Service (VPLS) Lab 10: Applying Equal-cost Multi-path Protocol (ECMP) within SDN networks 4
SDN Lab Series The goal of the SDN Lab Series is to provide a practical experience to students and IT practitioners The labs provide background information which is reinforced with hands-on activities A good book on SDN network (which matches the SDN Lab Series) is Software Defined Networking, A Comprehensive Approach 5
Organization of Lab Manuals Each lab starts with a section Overview Objectives Lab settings: passwords, device names Roadmap: organization of the lab Section 1 Background information of the topic being covered (e.g., Introduction to SDN) Section 1 is optional (i.e., the reader can skip this section and move to lab directions) Section 2 n Step-by-step directions 6
