== Message passing == |

* Haskell implementation? |
|||
* Optimizing for space and reliability: Sharing catalogs and availability |
|||
* Draft desired API |
|||
* Implement current meshboard with [[Tubes]] |
|||
== Notes == |
|||
API: ? FUNC: store 10k of a 1m file for the community |
|||
''on State'' |
|||
'''State''': M_ij - connected? dropped? new? |
|||
--> store trafic/cache state, draw pretty pictures |
|||
Move guys around |
|||
Create and query objects [KNOBS?] |
|||
''algorithm'' |
|||
Resource::Ad/Music/Pix/SW |
|||
Add:: Post/Make-available |
|||
(1) '''Add''': Store locally |
|||
Create handle ==> UID [hash?], summary [thumb, precis, author+date] |
|||
summary lets them do local search without having the whole thing |
|||
Each peer asks for others' handles and with some probability the actual resource |
|||
probability depends on size, popularity, space, other; compare <tt>Time To Leave</tt> |
|||
Q: poll v. push? |
|||
recipient has final say, including cache & expiry |
|||
(2) '''Retrieve''': Compute query |
|||
for all peers, send query (peer remembers Q). [if local, maybe punt, else search for more] |
|||
for all new associations, send Q [timeot?[] |
|||
at some point, Q --> H or R [done] |
|||
given H, for all peers, send H [store if found] |
|||
''open questions'' |
|||
* how to order reqs for pieces -- first part of a web page first? |
|||
* how to retrieve/split up a large file into many pieces? lockss, filenets. |

The MeshBoard activity is a way to share requests for and offers of content, services, or anything else. It currently uses an xml-rpc server as part of the activity, to work on all sorts of networks; but is being updated to use the mesh and presence service.
