Simulating Gigabit Speeds

If you aren’t quite ready to set up a multi-site gigabit network, you can also simulate gigabit speeds with a special node type called a delay.

The delay node allows you to configure extra characterists such as link capacity, packet loss rates, and general latency. This is useful for capping your connection speed to other nodes, or simulating a less-than-desirable environment for your app. After all, in reality, latency and packet loss are real issues that must be dealt with.

Changing Network Speed Artificially

In the image below, we have two nodes that have yet to be networked together:

../_images/core-delay-setup.png

In the resource list drop down, we’re going to select the ‘delay’ option:

../_images/core-delay-select.png

From there, we’ll want to drag a delay node (or two) onto the pane

../_images/core-delay-drag.png

Finally, let’s drag links between the nodes so the LANs are set up automatically:

../_images/core-delay-topology.png

At this point, let’s click the i icon on the delay node. We’ll see a properties pane appear with an area to set the link capacity.

Apply your settings, and you can now build and run your app as if you’re on a gig network.
