The Mesh WAN
ø
I’ve added some thoughts drawn from 15 years supporting lousy WAN infrastructures to a brief story here.
[Summary] Maintaining outmoded ISDN, ATM and frac-T/E’s really make the corporate-wan hub and spoke model more difficult than the practice. The VoIP/SIP model encourages corporate-WAN architects to move beyond the telco physical end-to-end mentality and think in 21st century tunnel terms, or at least investigate Groove and P2P swarming as the next model.
