Freemount

Summary

Freemount is a network filesystem protocol. It runs over a reliable transport medium, such as local sockets, TCP, TLS, and SSH.

Freemount's key features include

• extended semantics, including operations like select()
• low latency
  • small requests can be batched together in a single packet
  • messages can be interleaved -- a large read or write needn't block other requests
    • unrelated requests can be parallelized
  • related requests can be merged into chains -- if one fails, the rest abort
  • related requests can be combined, e.g. open/write-fd/close -> write-path

Freemount is designed to be the optimal protocol for FORGE (the File-Oriented, Reflective Graphical Environment).
