NePA TesT: Community Network Emulator

Mininet Examples These examples are intended to help you get started using Mininet's Python API. --- baresshd.py: This example uses Mininet's medium-level API to create an sshd process running in a namespace. Doesn't use OpenFlow. consoles.py: This example creates a grid of console windows, one for each node, and allows interaction with and monitoring of each console, including graphical monitoring. controllers.py: This example creates a network and adds multiple controllers to it. emptynet.py: This example demonstrates creating an empty network (i.e. with no topology object) and adding nodes to it. linearbandwidth.py: This example shows how to create a custom topology programatically by subclassing Topo, and how to run a series of tests on it. miniedit.py: This example demonstrates creating a network via a graphical editor. multiping.py: This example demonstrates one method for monitoring output from multiple hosts, using node.monitor(). multipoll.py: This example demonstrates monitoring output files from multiple hosts. multitest.py: This example creates a network and runs multiple tests on it. scratchnet.py, scratchnetuser.py: These two examples demonstrate how to create a network by using the lowest- level Mininet functions. Generally the higher-level API is easier to use, but scratchnet shows what is going on behind the scenes. simpleperf.py: A simple example of configuring network and CPU bandwidth limits. sshd.py: This example shows how to run an sshd process in each host, allowing you to log in via ssh. This requires connecting the Mininet data network to an interface in the root namespace (generaly the control network already lives in the root namespace, so it does not need to be explicitly connected.) treeping64.py: This example creates a 64-host tree network, and attempts to check full connectivity using ping, for different switch/datapath types. tree1024.py: This example attempts to create a 1024-host network, and then runs the CLI on it. It may run into scalability limits, depending on available memory and sysctl configuration (see INSTALL.)
