Private Network

• What is a Private Network?
• A network of devices that can communicate between each other, but does not communicate with any other set (for example, the LAN, or the Internet).
• Private networks help to reduce traffic clutter
• Scientific computation is serious business; Separate it from browsing for movie songs
• Certain classes of IP addresses have been designated as Private. For example, the series, 10.0.0.x (or), 192.168.x.x cannot be used by any computer on the Internet.
• Private IPs can be used within a campus too, to improve security.
• But one wants to communicate to the cluster also. Say, for submitting jobs, to access data etc.. To do this, one needs to set up a gateway between the private network of the cluster and the LAN.
• The gateway can be housed within the Master node
