1. Gigabit-per-second networks have entered the mainstream.
- Myrinet, Gigabit Ethernet, etc.
2. Commodity hosts have I/O speeds to match.
- 32-bit, 33MHz PCI delivers > 1Gb/s bandwidth
double the bus width, or double the clock: double the bandwidth
3. But: hosts still canít keep up!
- Typical gigabit ethernet links deliver < 0.5 Gb/s over TCP.
- Is this due to OS, hardware, TCP limits, gremlins?
4. How can we deliver gigabit-per-second performance to TCP/IP applications?
- How fast can TCP really go?
