Dumbbell Topology

The simulation was made with eLab You can also do it (for free).

Dumbbell topology is a very common concept in computer networks. The Dumbbell topology shows a number of nodes(usually more than 2) connected to a single router. The router is connected to another router over a serial slow link. A group of nodes are connected to that router, creating the dumbbell topology. The Dumbbell topology is used to display common network scenarios. For example , a group of computers are trying to connect to a group of servers all sharing a slow bandwidth serial link. In our simulation we show a simple dumbbell topology of 2 senders and 2 receivers. The receivers and senders are connected with a fast ,10Mbps, links with various delays. The Routers in the middle are connected with a slow link of 1Mbps and 100ms delay.
