Lync Server / UCMA 3.0中的受信任应用程序具有多个应用程序端点？ [英] Trusted Application in Lync Server/UCMA 3.0 to have multiple application endpoints?

问题描述

（也许这是这个问题的正确位置？）

我知道同时在线状态订阅数量的限制是有原因的，如果10000个人每个持续订阅所有其他9999，它会给出太高的性能影响。但是在这里我们只需要* * *，我们的应用程序，订阅每个人的
。

与OCS相比，Lync Server似乎简化了应用程序端点的问题，是"受信任的应用程序"。打开门。我知道一个应用程序可以有多个端点，但我想知道这是否可以按照我的想法使用：

• 如果有更多的人和端点可以订阅，相同的受信任的应用程序可以创建更多的端点并绕过该限制吗？ （一个端点将为例如1000个用户订阅"状态"存在，然后将创建一个新端点
  并订阅接下来的1000个用户......）我想在我的程序中我可以拥有所有事件关于一个应用程序端点路由到一个处理程序/帮助程序对象，一个为每个附加点实例化 - 但我不确定我是否正确推理...？
  
• 或者，状态订阅的限制是在应用程序上，而不是在每个端点上？
  
• Lync Server中的限制是否与OCS 2007 R2中的限制相同？ Lync Server的限制是什么？
  

解决方案

是的，这是我们文档中的建议之一：  http://msdn.microsoft.com/en-us/library/gg437468.aspx

（我们文档中的摘录）

有多种方法可以解决大量持久订阅的问题，导致Lync Server 2010出现错误响应。

• 
  

  由于限制适用于每个端点，因此应用程序可以创建多个观察程序端点来分配负载。

  
  
• 
  

  由于限制适用于每个Lync Server 2010池，因此管理员可以跨多个池分配用户以分配负载。

  
  
• 
  

  作为处理大量订阅的最佳做法，它建议UCMA 3.0应用程序限制其订阅的类别数量。这可以通过在创建端点时提供过滤器来实现。通过限制
  类别数量，允许更多订阅。

  
  

(Maybe this is the right place for this question?)

I know the limit for the number of simultaneous presence subscriptions is there for a reason, it would give a too high performance hit if 10000 people each persistently subscribed to all the other 9999. But here we want just *one*, our application, to subscribe to everyone.

It seems Lync Server has simplified matters with Application Endpoints compared to OCS, being a "Trusted Application" opens the doors. I know an application can have multiple endpoints, but I wonder if this can be used in the way I think:

• If there are more people than and endpoint can subscribe to, can the same Trusted Application create more endpoints and go around that limit? (One endpoint would subscribe to "State" presence for eg. 1000 users, then a new endpoint would be created and subscribe to the next 1000 users...) I suppose in my program I could then have all events concerning one application endpoint routed to a handler/helper object, one instansiated for each appendpoint - but I'm not sure I'm reasoning correctly there...?
• Or would the limit on presence subscriptions be on the application and not on each endpoint?
• Are the limits in Lync Server the same as in OCS 2007 R2? What are the Lync Server limits?

解决方案

Yep, that's one of our recommendations in our documentation: http://msdn.microsoft.com/en-us/library/gg437468.aspx

(snippet from our documentation)

There are several ways to deal with the problem of a large number of persistent subscriptions, resulting in an error response from Lync Server 2010.

• Because the limit is for each endpoint, the application can create multiple watcher endpoints to distribute the load.

• Because the limit is for each Lync Server 2010 pool, the administrator can distribute users across multiple pools to distribute the load.

• As a best practice for dealing with a large number of subscriptions, it is recommended that a UCMA 3.0 application limit the number of categories it subscribes to. This can be accomplished by supplying a filter when the endpoint is created. By limiting the number of categories, more subscriptions are allowed.
