Web Application Messaging Protocol
WAMP is a WebSocket subprotocol registered at IANA, specified to offer routed RPC and PubSub. Its design goal is to provide an open standard for soft, real-time message exchange between application components and ease the creation of loosely coupled architectures based on microservices. Because of this, it is a suitable enterprise service bus (ESB), fit for developing responsive web applications or coordinating multiple connected IoT devices. Characteristics Structure WAMP requires a reliable, ordered, full-duplex message channel as a transport layer, and by default uses Websocket. However, implementations can use other transports matching these characteristics and communicate with WAMP over e.g. raw sockets, Unix sockets, or HTTP long poll. Message serialization assumes integers, strings and ordered sequence types are available, and defaults to JSON as the most common format offering these. Implementations often provide MessagePack as a faster alternative to JSON at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WebSocket
WebSocket is a computer communications protocol, providing a full-duplex, simultaneous two-way communication channel over a single Transmission Control Protocol (TCP) connection. The WebSocket protocol was standardized by the Internet Engineering Task Force, IETF as in 2011. The current specification allowing web applications to use this protocol is known as ''WebSockets''. It is a living standard maintained by the Web Hypertext Application Technology Working Group, WHATWG and a successor to ''The WebSocket API'' from the World Wide Web Consortium, W3C. WebSocket is distinct from HTTP used to serve most webpages. Although they are different, states that WebSocket "is designed to work over HTTP ports 443 and 80 as well as to support HTTP proxies and intermediaries", thus making it compatible with HTTP. To achieve compatibility, the WebSocket Handshake (computing), handshake uses the HTTP/1.1 Upgrade header, HTTP Upgrade header to change from the HTTP protocol to the WebSocket pro ...
