open virtual topology simulator

We have hosted the application open virtual topology simulator in order to run this application in our online workstations with Wine or directly.

Quick description about open virtual topology simulator:

Features:

• OpenVTSimulator is Virtual Topology Simulator, which can spawn hybrid network on a host machine. The spawned network can consist VirtualMachines, NameSpaces and Switches as nodes.
• OVTSimulator uses OpenVSwitch commands to configure switches and QEMU for managing VMs.
• User can attach any SDN Controller with topology if it is needed.
• It uses Network Namespaces and Virtual Machines as hosts and openvswitch as switches.
• The script is written in Golang, also known as Google Go.
• To create a virtual topology, OVTSimulator takes Topology Configuration files as input, which is based on simple statements e.g. connect v1: v1-eth0, s1: s1-eth0
• User can control VM dynamically also e.g user can spawn/shutdown a VM or even create a new VM which is not mentioned in Topology file. There is no need to modify the config file and respawn the whole topology again.
• It can also configure different VLANs.
• OVTSimulator also configures DHCP server for VMs, that will assign IP address to VMs.
• On exit, OVTSimulator cleans every modification done to system e.g removing all temporary interfaces. It also send shutdown signal and brings all spawned VM down.
• This can be used to develop and test multiple POCs and innovations.
