Part 1: Design and Setup In this tutorial we are going to use Open vSwitch (OVS) as an OpenFlow switch connected to three hosts. OVS is a software switch running on a compute resource. The other three hosts can only communicate through the OVS switch. The experiment will need (the rspecs for this exercise are provided later in this section): 1 Xen VM with a public IP to run an OpenFlow controller 1 Xen VM to be the OpenFlow switch 3 Xen VMs as hosts   Step 1: Reserve Resources Go to add resources and add RSpec using the URL option a)  Reserve a VM that runs your OpenFlow controller. b) Reserve your network, that includes a VM with OVS installed. Step 2: Configure and Initialize Services Overview: Although OVS is installed and initialized on the host that is meant to act as a software switch, it has not been configured yet. There are two main things that need to be configured: (1) configure your software switch with the interfaces a...

Resources Geni Web Page Video Explanation Description  This module gives students experience generating and analyzing TCP flows. Students will use iperf to create a flow and view the sawtooth behavior. A second flow will then be introduced to show how TCP flows share a link. Objective Use iperf to generate TCP traffic Start the iperf server; this allows the node to receive iperf traffic. The ampersand(&) allows the command to run in the background while the console is in use. iperf -s & Start the iperf client; this opens a TCP connection to the iperf server on the server node and begins sending packets. The (-c) indicates that iperf should run in clinet mode and it should connect to the host named "server." The "-i 10" tell iperf to print updates every 10 seconds and "-t 180" indicates that the client should run for 180 seconds before closing the connection. iperf -c server -i 10 -t 180 & Have an understanding of how...

Solving Modern Programming Challenges with Go Takes much of the overhead out of object-oriented development to focus on code reuse Has a garbage collector Development Speed Uses a smart compiler and simplified dependency resolution algorithms Compiler only looks at libraries that re included in the entire dependency chain Needs a test suite to avoid discovering incorrect type bugs at run time Concurrency Go's concurrency support is one of its strongest features goroutines are like threads but use less memory and require less code Creates a model where you can send data between goroutines rather than letting goroutines fight to use the same data Goroutines Goroutines are functions that run concurrently with other goroutines Many goroutines execute on a single thread Goroutines use less memory than threads and the Go run time will schedule the execution of goroutines against a set of configured logical processors Each processors is bound to a single OS thread which makes more effici...
