Abstract: |
TCP-over-OBS is a promising transport paradigm to support
next-generation Internet. Load-balanced routing generally
improves loss performance over OBS. We identify that implementing
TCP over load-balanced OBS could lead to persistent out-of-order
delivery of TCP segments resulting in unnecessary timeouts and
fast retransmissions. In this paper we evaluate High-Speed Reordering-Robust TCP (HS-RR-TCP)
over OBS networks and compare HS-RR-TCP to an OBS layer approach called source ordering. Through extensive simulations
we show that HS-RR-TCP achieves significant improvement in TCP performance. We also
find that source ordering provides minimal improvement over the higher layer
HS-RR-TCP approach. |
