Fujitsu Computer Systems 2 1. Protocoles pour e-Business / e- Gouvernement

Fujitsu Computer Systems 3 Protocoles de base: HTTP (hypertext transport protocol) SMTP (simple mail transfer protocol) FTP (file transfer protocol) Chacun definit: - un ensemble de commandes de base ( GET, POST … for HTTP) - un format pour envelopper des donnees (document, fichier … ) Au dessus du protocole Internet (TCP / IP): HTTP URL: SMTP: TCP / IP HTTP SMTP FTP

Fujitsu Computer Systems 4 Protocoles de base: SMTP (simple mail transfer protocol) Pour la reception Finale: IMAP POP3 Status reply

Fujitsu Computer Systems 7 Digital signature Securite du MIME: S/MIME

Fujitsu Computer Systems 10 SOAP: Simple Object Access protocol - Structure du message: une envelope XML independante du niveau transport: SOAP header SOAP body TCP / IP HTTP SMTP SOAP SOAP avec Attachements (MIME)

Fujitsu Computer Systems 11 SOAP: Une plateforme protocolaire pour des extensions modulaires (ajouts de fonctions de securité, fiabilite, correlation/addressage, etc.) (SOAP extensions header blocks) Les deux facettes de SOAP - mode RPC : message = invocation de procedure - mode document : message = envelope pour doc. SOAP SOAP avec Attachements (MIME) SécuritéFiabilité Corrélation adressage

Fujitsu Computer Systems 13 Extensions SOAP Un mecanisme d extensions modulaires: header blocks dans the SOAP Header Toutes les specs Web services de niveau protocole utilisent ce mecanisme WS-Security WS-Reliability / WS-ReliableMessaging WS-Addressing WS-SecureConversation ….

Fujitsu Computer Systems 14 Une alternative à SOAP: REST (Representational State Transfer) - HTTP seulement - davantage un style qu un protocole bien defini - pas d enveloppe XML structuree comme SOAP - moins complexe, mais plus limité (sécurité, robustesse) TCP / IP HTTP SMTP SOAP REST
