将HTML5允许Web应用程序做出的对等的HTTP连接？ [英] Will HTML5 allow web apps to make peer-to-peer HTTP connections?

问题描述

是否有可能创建一个web应用程序，与中央服务器的帮助下，可以创建具有相同的Web应用程序的其他用户直接连接？我想象类似打洞的过程。

我读过关于HTML 5中的新的WebSockets API，但现在看来，你必须启动完全全双工连接，就可以开始前，用WS-兼容的服务器的连接。我moreso思考过程，使客户端之间的直接连接，与服务器介入的只有的初始握手。

注：Java小程序不计。我只是在标准的浏览器技术的兴趣。

解决方案

而不是智能的猜测，这里是一个明智的回答：

HTML 5计划允许点对点从JavaScript的连接，但这些连接不会被原始TCP。

Is it possible to create a web app that, with the help of a central server, could create direct connections with other users of the same web app? I'm imagining a process similar to UDP hole punching.

I've read about the new WebSockets API in HTML5, but it appears you must initiate the connection with a WS-compatible server before the fully-duplexed connection can begin. I'm thinking moreso about a process to make direct connections between clients, with a server getting involved only in the initial handshake.

NOTE: Java applets don't count. I'm interested only in standard browser technologies.

解决方案

Instead of intelligent guesses, here is an informed answer:

HTML 5 plans to allow peer to peer connections from javascript, but these connections WILL NOT BE RAW TCP.

The complete spec can be found at http://dev.w3.org/html5/websockets/

EDIT: with specific reference to peer to peer connections, check out these links:

• Regarding peer to peer connections: http://www.w3.org/TR/2008/WD-html5-20080122/#peer-to-peer
• Regarding broadcast connections to the local network: http://www.w3.org/TR/2008/WD-html5-20080122/#broadcast
• Regarding TCP connections (in the encoded protocol): http://www.w3.org/TR/2008/WD-html5-20080122/#tcp-connections
• Complete proposed spec: http://www.w3.org/TR/2008/WD-html5-20080122/#network

Its important to note that the capabilities are still being negotiated. It will be nice to be able to create "local chat" web apps :)
