Network simulation

This application simulates and visualises network routing and message transmission in the network of defined topology.

Prerequisites

1. Python 3.6.8
2. pip 19.1.1
3. make

Getting started

To start the application, run

make run

This will download virtualenv and create a new local environment if you don't have them, install needed dependencies and run the server.

Visit http://localhost:5000 in your browser to use the service UI.

Functionality

Start up

The service creates an arbitrary network topology according to pre-defined configurations.

Topology manipulations

You can add nodes and edges by using corresponding buttons in the top left corner.

You can delete nodes and edges by selecting them and clicking "Delete" button.

You can change edge type (duplex, half-duplex) by double-clicking the edge.

Routing

You can inspect node's routing table by double-clicking the node.

You can simulate message transmission between two nodes by using the top right button. You can choose message and packet size, as well as, the transmission type (virtual circuit mode, datagram mode) in the modal window. The application will calculate the route, number of service and data packets sent, time, service traffic, and data traffic of such transmission.

Plots

You can generate a few plots available in Ukrainian.

Service traffic

GET request to /service-traffic will generate plots describing service traffic to message size and service traffic to packet size relations.

Time

GET request to /time will generate plots describing transmission time to packet size and transmission time to number of intermidiary nodes relations.
