Description:

   The simplest and easily understandable network is the default topology, comprising a wireless access point with two wireless stations indued in a switch connected to a controller. These stations are specified as hosts. The Ping tool tests whether a particular host is reachable across an IP network and quantifies the time it takes for packets to be sent from the local host to a destination computer and get it back. The PingAll is a straightforward comfort application with a less simple excellent purpose that facilitates the simple crisp commands for pinging up multiple IP addresses in a given span to examine the connectivity between the local machine and multiple remote computers at the same time. It exhibits the connectivity between all hosts and tells the user which hosts are connected to each other. The second host sees the ARP request and sends an immediate replication. This replication goes to the controller, which sends it to the first host and bumps down a flow entry. Now the first host knows the MAC address of the second, and it can send its ping via an ICMP Echo Request. The Ping is a command-line utility attainable on any OS with network connectivity that acts as a test to see if a networked device is convenient. The following sample explains the users how to Test the Connection Between Hosts within MiniEdit,

  Create a simple network topology in MiniEdit’s simulator.

  Start the simulation.

  The command to test the connectivity among hosts is:

  Mininet> pingall

  This command will make each host in the network ping every other host in the network.

  In the network, h1 will ping h2, and h2 will ping h1.

  The successful pings indicate that all the links in the network are active.
