Abstract

A method of configuring a virtual network comprises: running a user-interactive business requirements wizard from a server, the wizard collecting business requirements from a user; translating the business requirements into technical requirements for a network configuration using the server; selecting a network configuration from a network configuration database using the server, the selecting utilizing the technical requirements; testing the network configuration using a processor; monitoring the testing and generating new facts regarding performance of the network configuration, using the processor; feeding back the new facts to the server for use by the server in the selecting; and repeating the selecting, testing, monitoring and generating, and feeding back, until the server determines a criterion for network stability has been reached. The method may include automatically discovering local network characteristics using a networking device, prior to the selecting, sending the characteristics to the server for use by the server in the selecting.
