Internet2 TCP Single stream Land Speed Record measurement
System
- Server configuration
- CPU: Dual AMD Opteron 248, 2.2GHz
- Mother Board: RioWorks HDAMA rev. E
- Memory: 1G bytes, Corsair Twinx CMX512RE-3200LLPT x 2, PC3200, CL=2
- OS: Linux kernel 2.6.14
- Disk Seagate IDE 80GB, 7200r.p.m. (disk speed not essential for performance)
- Network interface card
- Chelsio N110 (10GBASE-SR)
- PCI-X/133 MHz I/O bus connection
- Network hardware
- SANSEI-system TGNLE-1 receiving-side pacing device
Technical points
- (1) IPv6 packets
- (2) 9130B Jumbo frame
- (3) Use of "inter-layer coordination optimization" in TCP[1](Adjusting output rate using Chelsio N110 feature)
- (4) single stream TCP
- (5) All the trans continental connections are WAN PHY based.
- (6) IPv6 communication is almost as fast as that of IPv4.
Target Performance of single stream TCP on 30,000(actual 32,372) km circuit
- 6.96 Gbps (TCP
payload), standard frame -> 208,800Terabit meter / second (Internet2 LSR approved Single/Multi TCP Stream record)
