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
Introduction to Mininet Lab activities are described in Lab 1, SDN Lab Series 2
What is Mininet? A virtual testbed capable of recreating realistic scenarios1 It enables the development and testing of network protocols Inexpensive solution, real protocol stack, reasonably accurate Switches Host Host Host Host Host Host Hardware Network Mininet Emulated Network 1Mininet website, http://mininet.org/ 3
What is Mininet? Mininet nodes are network namespaces Each node has different / separate virtual interfaces, routing tables Nodes use the underlying protocol stack of the host device Nodes are connected via virtual Ethernet (veth) links, which behave as Ethernet links 4
Pod Design with Mininet A pod is a set of virtual equipment (routers, switches, etc.) A pod is created every time a lab reservation is made For the Software Defined Network (SDN) Lab series, pods are embedded into Mininet Intel Xeon Gold 6130 CPU, 2.1 GHz 5
