MFS: a Network-Aware Mobile File System, Lecture notes of Computer Networks
The MFS mobile file system developed by Benjamin Atkin and Kenneth P. Birman at Cornell University. It focuses on the need for bandwidth adaptation in mobile hosts and the use of modeless adaptation based on active RPCs. It also discusses the cache consistency algorithm and its effects on write delay and consistency. The document concludes by stating that modeless adaptation in MFS looks promising and that further investigation is needed in other application domains and environments.

Bandwidth adaptation
ß Mobile hosts see wide bandwidth variations
ß Adaptation is required for good performance
ß Traditionally adapt to bandwidth via modes ß Coarse-grained ß Can underutilise
ß Alternative: adapt modelessly based on the current active RPCs
