TCP/IP Transfer Tests
This page documents the tests that i've performed using various new and old stacks using the TCP/IP protocol. It focuses on the new TCP protocols for High Latency, high bandwidth environments.
Links and Background
| Description | |
| HSTCP | HSTCP is a protocol developed by Sally Floyd which involves adpatively changing the cwnd according to its size. Here. |
| ScalableTCP | Developed by Tom Kelly, it uses MIMD to achieve high throughput and stability. Here. |
| FAST | Developed by Caltech, it uses the Vega core to judge the the delay from ACKs to judge how much to put onto the network to avoid congestion. Here. |
Testbeds
MB-NG @ 1Gb/sec bottleneck
The MB-NG network is a high bandwidth low latency network in the UK. Max Capacity 2.5Gb/sec, latency LON->MAN = 6msec.
| Description | |
| pktdrop | Loss induction at recv to simulate differing network environments. Results here. |
| cbr bg | Various cbrbg loads were generated with udp iperf and tcp run on top. Results here. |
| similar bg | Self Similar udp traffic was sent through the network and tcp run over it. Results here. |
Datatag @ 1Gb/sec bottleneck
The DataTAG testbed is a high bandwidth, high latency network stretching across the Atlantic from Geneva to Chicago. Max Capacity is now 10Gb/sec.
