“TPZ/IP” Motivation, Part II
1. How fast does TCP really go, and at what cost?
- TCP insiders assume modern TCP is “safe at any speed”.
delivers wire speed if error rates and latency are good
- Others have proposed “lightweight” alternatives.
- Deployment of the VI standard for user-level networking is targeted even where latency is not paramount.
e.g., internal communication in Internet server farms
2. “Because it was there.”
