Dynamic analysis of the arrow distributed protocol
2004
Proceedings of the sixteenth annual ACM symposium on Parallelism in algorithms and architectures - SPAA '04
Preserved Fulltext
We present a novel and comprehensive competitive analysis of the arrow protocol. ...
The arrow protocol is a solution to distributed queuing that is based on path reversal on a pre-selected spanning tree of the network. ...
Another queuing protocol is the dynamic distributed object manager protocol by Li and Hudak, as implemented in their Ivy system [15] . ...

An unresolved problem in physics is how the thermodynamic arrow of time arises from an underlying time reversible dynamics. ...
Among other interesting properties, the length of time's arrow bounds the average dissipation and determines the difficulty of accurately estimating free energy differences in nonequilibrium experiments ...
It is enlightening to contrast the length of time's arrow with the hysteresis, the average dissipation of the forward and reverse protocols, h½Ã ¼ 1 2 hW½xjÃi à þ 1 2 hW½xjÃiÃ: (10) Because of Eq. (5), ...
