New page

A comm system is a module which manages [[proxy|proxies]] for [[reference|references]] which cross a [[vat]] boundary. [[E-on-Java]] has two built-in comm systems, [[Pluribus]] and [[boot-comm]].

Replacing the name “comm system” has been considered because it is too generic; however, no adequate replacement has yet been agreed upon. Discussion: [http://www.eros-os.org/pipermail/e-lang/2007-March/011928.html on e-lang], [http://www.eros-os.org/pipermail/cap-talk/2007-March/007586.html on cap-talk].

= Comm system responsibilities =

Besides providing a proxy handler to send messages, a comm system must do these things, if their conditions arise:

* If a reference becomes [[broken]], respond to all [[Miranda whenBroken|__whenBroken]] messages it received.
* If a remote promise becomes [[more resolved]] (including becoming [[broken]]), respond to all [[Miranda whenMoreResolved|__whenMoreResolved]] messages it received.
* Ensure that two separately-created proxies for the same remote reference are the [[same]], or that only one proxy per reference is created (the exact means depends on the proxy maker being used).
