I want to model a data center and its connections to end user by adding number of hops(switches/routers) in between showing a geographically far data center location from its client and another data center with proximity near to the client. Taking all parameters into consideration like latency due to various reasons in both cases and comparing them. I want to add software defined networks in between the data center and end user. kindly suggest me some tool in which i can design a complete network with opion of choosing the type of wires , routing algorithms etc. so that we can optimally deliver the cloud traffic to end user.
