Dynamic right-sizing in TCP : a simulation study /

Description

Virtually all network applications requiring reliable end-to-end communication depend on TCP. Unfortunately, the performance of any stock TCP is abysmal over wide-area networks (WANs) and even over local area networks (LANs) with wry high-bandwidth links. Currently, network researchers manually optimize TCP buffer sizes to achieve acceptable performance over a given connection. Unfortunately, this manual optimhtlon requires changes to the kernel on both end hosts involved in the network connection (changes that are only effective far connections Iuctween thesse two hosts). Furthermore, betruse two administrative domains must be coordinated to perform this optimization, thia process can be tedious and t h ... continued below

Description

Virtually all network applications requiring reliable end-to-end communication depend on TCP. Unfortunately, the performance of any stock TCP is abysmal over wide-area networks (WANs) and even over local area networks (LANs) with wry high-bandwidth links. Currently, network researchers manually optimize TCP buffer sizes to achieve acceptable performance over a given connection. Unfortunately, this manual optimhtlon requires changes to the kernel on both end hosts involved in the network connection (changes that are only effective far connections Iuctween thesse two hosts). Furthermore, betruse two administrative domains must be coordinated to perform this optimization, thia process can be tedious and t h e consuming. To address these prohlem, this paper illustrates the benefits of B new technique called dynamic right-sizing. This technique dynamically and automatically determines the best buffer size, and hence flow-cantwl window size in TCP. Our simulation dtndy shows that dynamic right-sizing can Improve the performance of Rows by two orders of magnitude over stock TCP implernentations ihat have static flow-control windows.
