Take a deep breathe and jump into this whirlwind eComm presentation from Cullen Jennings, Cisco's Distinguished Engineer, on Network Address Translations (NATs), how they work, what's going on and more importantly, why we should care.
In his densely informative presentation, Jennings looks at if, and when, we're really going to run out of IP addresses, how ISPs are using this to avoid the network neutrality push, and the disturbing implications ISP 'Carrier Grade NATs' have for application developers and end users alike.
From Echo and Relay media servers, hole-punching and latency to the real meaning behind ISP 'network management policies', Jennings' presentation is packed with information but has a simple take-home message.
