Anotation

ISO/IEC 24824-2:2006 specifies the messages required for Fast Web Services. It provides the specification of ASN.1 SOAP messages which carry the same semantics as W3C SOAP messages. The exchange of ASN.1 SOAP messages provides Fast Web Services. ISO/IEC 24824-2:2006 references other ASN.1 International Standards and the Web services specification W3C SOAP 1.2 to fully define application exchanges that use Web protocols and W3C SOAP functionality. This is an extension to the provision of Web services using W3C SOAP messages, without any change to the functionality of W3C SOAP and service description languages. The main change is to the use of compact and easily-processed binary encodings of XML data, rather than character encodings. The use of ISO/IEC 24824-2:2006 (with the ASN.1 SOAP messages encoded using the ASN.1 Packed Encoding Rules, PER) allows applications to provide Web services using messages that require less network bandwidth and less processing power (and hence provide a higher transaction processing rate) than use of the character encoding of XML data. ISO/IEC 24824-2:2006 also specifies a Multipurpose Internet Mail Extensions (MIME) media type that identifies an ASN.1 SOAP message encoded in PER. It also specifies a MIME media type that identifies a W3C SOAP message infoset encoded as a fast infoset document (see ISO/IEC 24824-1). Both of these encodings are used by ISO/IEC 24824-2:2006. LISO/CEI 24824-2:2006 specifie les messages necessaires pour les services web rapides. Elle specifie les messages SOAP en ASN.1 qui portent la meme semantique que les messages SOAP du W3C. Lechange de messages SOAP en ASN.1 donne les services web rapides. LISO/CEI 24824-2:2006 fait reference a dautres Normes internationales de lASN.1 et a la specification des services web SOAP 1.2 du W3C pour definir completement les echanges dapplication qui utilisent les protocoles web et les fonctionnalites SOAP du W3C. Elle est une extension de la fourniture des services web en utilisant les messages SOAP du W3C, sans aucun changement aux fonctionnalites du protocole SOAP du W3C et des langages de description de service. Le principal changement est lutilisation de codages binaires compacts et faciles a traiter de donnees XML, plutot que les codages de caracteres. Lutilisation de lISO/CEI 24824-2:2006 [avec les messages SOAP en ASN.1 codes en utilisant les regles de codage compact ASN.1 (PER, packed encoding rules)] permet aux applications de fournir des services web en utilisant des messages qui exigent moins de bande passante reseau et moins de puissance de traitement (et donc de fournir un debit de traitement de transaction plus eleve) que le codage de caractere des donnees XML. LISO/CEI 24824-2:2006 specifie aussi un type de support dextensions de messagerie Internet multi-objet (MIME, multipurpose Internet mail extensions) qui identifie un message SOAP en ASN.1 code en PER. Elle specifie aussi un type de support MIME qui identifie un infoset de message SOAP du W3C code comme un document fast infoset (voir lISO/CEI 24824-1). Ces deux types MIME sont utilises par lISO/CEI 24824-2:2006.
