信息技术.ASN.1普通应用:快速网络服务

[中文适用范围]： 此建议|国际标准规定了能够使用快速网络服务的消息和编码，以及描述此类服务的方法。 用于支持这些服务的协议满足 SOAP 处理模型的要求（参见 W3C SOAP 第 1 部分第 2 条），并且基于以下传输： a) 包含嵌入的 ASN.1 编码值和嵌入的 ASN.1 SOAP 消息快速信息集文档； b) 快速信息集 SOAP 消息。 此建议|国际标准还规定： – ASN.1 SOAP 的 ASN.1 模块，定义信封类型（该类型的值对应于 ASN.1 SOAP 消息）； – ASN.1 SOAP 消息和 W3C SOAP 消息之间的概念映射（定义为 XML 信息集的实例，参见 W3C SOAP 第 1 部分第 5 条）； – W3C SOAP 处理模型的扩展，用于处理嵌入的 ASN.1 编码值； – ASN.1 SOAP HTTP 绑定，它是 W3C SOAP HTTP 绑定的修改和扩展（参见 W3C SOAP 第 2 部分，第 7 条），用于 ASN.1 SOAP 消息的传输； – 支持使用 W3C SOAP HTTP 绑定将序列化为快速信息集文档（快速信息集 SOAP 消息）的 W3C SOAP 消息信息集传输（参见 W3C SOAP 第 2 部分，第 7 条）； – 面向 SOAP 的服务描述，定义快速 Web 服务的接口和语义。 分配两个多用途互联网邮件扩展（MIME）媒体类型名称来标识： – 使用基本对齐 PER 编码的 ASN.1 SOAP 消息； – 快速信息集 SOAP 消息。 [外文原描述]： 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.
