comparison with irc
- similarities :
- channels
- pms
- differences
- minimized delay : made realtime game data communication
- channel meta / mailboxes : larger messages (avatar pictures, maps) can be stored in server-side database and requested by id
reliable udp
<ghoulsblade> für ne reine udp brauchen wir noch confirm nachrichten <ghoulsblade> und config für resend-interval und timeout <ghoulsblade> evtl regelmässige roundtrip-time messung für dynamischen resend interval, damits so schnell wie möglich resendet wird bei störung aber nicht immer doppelt geschickt wird wenns keine störung gibt <ghoulsblade> vll sogar 2 typen von reliable <ghoulsblade> fast auf kosten von bandbreite und slow mit mehr längerem interval
notes
- website doc : optimized for game-jammers : api provided by lib first, technical internas later, not interesting, e.g. id resolve capsuled ?
- udp : ordering-group id ? ordered but unreliable, option to automatically get latest successfully transmitted in group.
<ghoulsblade> z.b. wenn client jedes frame die eigene position broadcastet, api packt automatisch ne nummer dazu <ghoulsblade> ne aufsteigende nummer, mit jedem broadcats um 1 erhöht <ghoulsblade> und man kann dann auf empfängerseite immer das letzte abrufen. wenn eins verspätet ankommt und man schon ne neuere nummer hat, wirds verworfen
