Service as a standard

"You cannot manage what you cannot monitor," goes the old It adage. So getting that visibility is the first step towards better network management, especially within complex the computing environment of a data centre is. With that purpose in mind, a relatively new technology, software defined networking (SDn), aims to take the intelligence out of networking hardware and put it into centralised software. this enables it to monitor and control those data packets, applications and services that run over the many different types of router, switch, bridge and gateway that comprise data-communications networks.
