可靠的udp广播库？ [英] Reliable udp broadcast libraries?

问题描述

是否有任何库将可靠性层置于UDP广播之上？

我需要尽快将大量数据广播到大量机器上，通常看来这样的问题一定已经解决了很多遍了，但除了Spread工具包（具有一定的病毒性许可）外，我什么都找不到（您必须在宣传最终产品的所有材料中都提及它，但我不确定我们的客户是否愿意这样做） 。

I need to broadcast large amounts of data to a large number of machines as quickly as possible, and generally it seems like such a problem must have already been solved many times over, but I wasn't able to find anything except for the Spread toolkit, which has a somewhat viral license (you have to mention it in all materials advertising the end product, which I'm not sure our customer will be willing to do).

我本人已经打算写这样的东西了（因为这样做非常有趣！），但决定先问一下。

I was already going to write such a thing myself (because it would be extremely fun to do!) but decided to ask first.

我也看过UDT（http://udt.sourceforge.net），但它似乎没有提供广播操作。

I looked also at UDT (http://udt.sourceforge.net) but it does not seem to provide a broadcast operation.

PS我正在看的东西像库一样轻巧-没有基础结构更改。

PS I'm looking at something as lightweight as a library - no infrastructure changes.

推荐答案

UDP多播如何？看看 PGM协议，该协议有几种商业和开源实现。

How about UDP multicast? Have a look at the PGM protocol for which there are several commercial and open source implementations.

免责声明：我是 OpenPGM ，该协议的开源实现。
