I have an application, where I need to add role-based messaging. The messages are generated ny the application itself, and every message have an starttime (where is show on the client message-window) and an expire-time. Depending on your role, you will see a subset of the messages. Some messages are VERY important, and should be pushed to the client instantly (we are talking milli-seconds - not seconds). Also - when a user log in, he/she should be the current messages for his/her role.

Basically this is a blackboard, where the client see a view of the blackboard (depending on the role). It has to be really fast and reliable, as it will be used in an emergency centre handling calls for ambulances and fire)

Anyone know which technology I should use (application is written in .NET 2.0) or if a product exists, which I could use?

您可以尝试使用Retlang。

你可以试试 GigaSpaces http://www.gigaspaces.com他们为黑板/消息系统提供了一个相当成熟的平台（你可以说是企业级的），具有对 Java 和 .NET 的支持以及处理黑板/队列/角色的能力非常细的品位粒度。

在我看来，这是一个梦想，Tibco RV / 多播的角色，如果您的组织有许可证/后端的资金......

如果没有，请查看 UDP 多播，您的服务器将在其中广播所有黑板事件，并且每个客户端将过滤需要显示的内容。

干杯，弗洛里安
