Outline• Introduction• NOX Overview• Programmatic Interface• Example Application
Introduction• What we clearly need is an operating system for networks, one
that would provide a uniform and centralized programmatic interface to the entire network.
• A network operating system would not manage the network itself; it would merely provide a programmatic interface. Applications implemented on top of the network operating system would perform the actual management tasks.
NOX Overview
Programmatic Interface• NOX’s programmatic interface is conceptually quite simple,
revolving around :• Events
Programmatic Interface (Cont.)• NOX’s programmatic interface is conceptually quite simple,
revolving around :• Network View and Namespace
Programmatic Interface (Cont.)• NOX’s programmatic interface is conceptually quite simple,
