Integreted environmetn (compiler + editor) to computer network's projecting. You can make this by easy and intuitive language.

Application using prefuse library to drawing graph of network. It doesn't use analyzer generators because of this, it shows how from beginning to the end make simple compiler.

		"RAM" = "1GB",
                "disk" = "80 GB") extends Desktop;

Upper code shows wide functionality of language. At first you can put simple definitions which extends predefined definitions of computer, switch or other. Next, there are definitions of networks. All of definitions can be used below them.

In this part, there are sub-networks and main network which use defined elements of network. Sub-networks and main network can define connections between parts of network.

Operator <> means “every at left connected with every at right”
Operator * means “the same as at the left side”
Operator ^ means “first element in expression”

These operators are helpful in creation of standart topologies of network: star, token ring and other.
