+1.When discussing different protocol models, folks should be required to explain a collection of relatively obvious cost/benefit differences, such as:
1. Latency/Delay 2. Transaction (Round-trip) exchange count 3. Robustness/fragility 4. Administration 5. Privacy 6. Authenticity/Spoofing ... For the SMTP push model (and ignoring the possible pull last-hop): 1. Low latency 2. A bit too chatty, but pipelining largely fixed this 3. History demonstrates high robustness 4. Low administration (only DNS MX) 5. Privacy is theoretically non-existent 6. Authenticity is demonstrably horrible d/ d/ -- Dave Crocker Brandenburg InternetWorking bbiw.net
