In the Aloft Network Diagram, we see how PoP1 PoP2 are connected to a Switch (Juniper Ex2300), and an Aloft Network Firewall hinders the connection. A network diagram is a visual representation of network architecture. As shown in the aloft network diagram below, the core concept of a network diagram is to map out the network's structure with a variety of different symbols and line connections. In EdrawMax Online, creating a network diagram is pretty simple. You can easily start creating a network diagram by selecting the right template from the template library, removing the existing elements that you do not need from the template, then adding the network components and naming them correctly. Lastly, you can draw the connections between components and share your aloft network diagram among your peers.
