There are two primary parts to the topology definition: the physical design, which is the actual layout of the wire (media), and the logical design, which defines how the media is accessed by the hosts. Pass the file and anybody can open it. hi well for starters a physical network design well, as the name implies, involves the physical connectivity of each of your hosts on the network. Don't replace tools that do a good job with a lesser tool that “does it all".... If the logical topology describes the data flows within a network, which not depend from the network's physical design, the physical topology displays in details the placement of all network's components, depicts the precise location of all computer and network devices, and cables linking them. A physical topology describes how network devices are physically connected - in other words, how devices are actually plugged into each other. They also include decisions on jumbo frames and on other network-related requirements such as DNS and NTP. – Any sort of discovery If you are using DCIM or network documentation software, you may choose to use the generic icons for higher-level layers and more specific icons/models as you drill down. This gives the routing algorithm more options for routing calls without needing to change the routes of the VPs, which is an expensive operation [2] . But it keeps going, because nowadays companies also require basic traits considered essential in a large multi-user environment, and Visio also lacks: – Audit trails At least not the way the industry usually utilizes the term “enterprise-grade”, I know… it is very self serving because I am responding on behalf of the vendor here, but (and please don’t take it the wrong way) this one is too easy, if I may: Just try it, you will love it!
