“…In the literature, 9 the authors have shown that using a TCP tunnel increases the goodput of a TCP flow when the socket buffer size of the tunnel TCP is approximately equal to the bandwidth-delay product of a network. However, effect of the socket buffer size of the end-to-end TCP on the end-to-end TCP performance has not been investigated.…”

“…The reason that using the tunnel TCP with the SACK option increases the goodput of the TCP flow is probably the same with that reported in the literature. 9 Namely, the tunnel TCP with the SACK option can retransmit lost packets immediately after an ACK packet is received, so that the goodput of the TCP flow is increased.…”

“…On the contrary, they also point out that the performance of end-to-end TCP improves under other conditions. 9 However, in these researches, effect of several factors, such as network parameters and TCP parameter configurations, on the end-to-end TCP performance has not been sufficiently investigated.…”

“…[7][8][9][10][11] Several researches regarding performance evaluation of end-to-end TCP with a TCP tunnel have also been done. 1,9,12 For instance, the authors of the literatures 1,9,12 point out that the performance of end-to-end TCP degrades under certain conditions. On the contrary, they also point out that the performance of end-to-end TCP improves under other conditions.…”

TCP tunnel is a technology that aggregates and transfers packets sent between end hosts as a single TCP connection. By using a TCP tunnel, the fairness among aggregated flows can be improved and several protocols can be transparently transmitted through a firewall. Currently, many applications such as SSH, VTun, and HTun use a TCP tunnel. However, since most applications running on end hosts generally use TCP, two TCP congestion controls (i.e., end-to-end TCP and tunnel TCP) operate simultaneously and interfere each other. Under certain conditions, it has been known that using a TCP tunnel severely degrades the end-to-end TCP performance. Namely, it has known that using a TCP tunnel drastically degrades the end-to-end TCP throughput for some time, which is called TCP meltdown problem. On the contrary, under other conditions, it has been known that using a TCP tunnel significantly improves the end-to-end TCP performance. However, it is still an open issue -how, when, and why is a TCP tunnel malicious for end-to-end TCP performance? In this paper, we therefore investigate effect of TCP tunnel on end-to-end TCP performance using simulation experiments. Specifically, we quantitatively reveal effects of several factors (e.g., the propagation delay, usage of SACK option, TCP socket buffer size, and sender buffer size of TCP tunnel) on performance of end-to-end TCP and tunnel TCP.
