Jabber e Google

Oggi la JSF, la Jabber Software Foundation ha proposto due estenzioni per l’ XMPP,
il Jingle e il Jingle Audio.

E Google nel frattempo ha rilasciato le sue Libjingle, implementazioni delle Jingle e delle Jingle-audio. Librerie che google talk usa per negoziare, stabilire e mantenere le sessioni p2p.

Le licence vengono rilasciate in Berkeley-style license

Incorporare le Libjingle nei vari software, dovrebbe consentire di interagire con Google Talk.

Grazie Jabber, grazie Google!

Aspettando un gateway sip/iax/h323, ovviamente.

La JSF dice:
“Grazie all’ impegno di Google negli standard open, la comunita’ di Jabber puo’ ora costruire una larga serie di nuove applicazioni, dalla voce e video al file sharing, gaming, application casting, shared editing, e whiteboarding

Client Alternativi

La concorrenza a Skype e’ iniziata.
Esistono almeno 4 client simili per funzionalita’:

  Skype Gizmo OpenWengo Google Talk
Licenza Proprietaria Proprietaria GPL Proprietaria
Codecs iLBC
iSAC		 iSAC
iLBC
GSM
g711U/A
enhanced G711
iPCM-wb 		AMR
AMR-WB
PCMA
PCMU
GSM		 PCMA
PCMU, G.723, iLBC. We are also evaluating the Speex codec. We also
support codecs from Global IP Sound: ISAC, IPCMWB, EG711U, EG711A
Protocolli Proprietario Sip Sip Sip,XMPP
IM si si si si
Video No[5] No Si No
Piattaforma Windows
Gnu/Linux		 Windows
Gnu/Linux
MacOSX		 Windows
Gnu/Linux[4]		 Windows[3]
Encryption AES Rijndel 256bit No No No
Http Proxy Si [1] ? Si[2] ?

Il client con il piu’ grande potenziale mi sembra OpenWengo. Usa SIP quindi e’ standard, e’ GPL
quindi e’ integrabile, e’ multipiattaforma, e ha una buona comunita’ di sviluppo.


[1]: Io ho testato solo la versione per Gnu/Linux. Non sembra supportato ne’ proxy-basic ne’ proxy ntlm con autorizzazione.
[2]: Per poter usare l’ http proxy, bisogna ricompilare openwengo con enable-http-tunnel=’yes’
[3]: Per ora supporta completamente solo Windows. Le altre piattaforme sono supportate solo per la parte di Instant Messaging (con client Jabber). Sembra pianificata cmq la versione completa per Gnu/Linux e MacOSX.
[4]: Pianificata l’ uscita per MacOSX e per PockePC Wince
[5]: “Rumori” dicono che per natale verra’ supportato il video.
Aggiornamento: sembra essere uscito il supporto video.
