我们讨论了分布式会话控制服务器的动态扩展。动态伸缩是指通过服务器动态加入或离开来更改系统配置。在会话控制服务器中，必须保证可用性和实时处理。因此，必须在确保这些要求的同时实现动态缩放。我们提出了一个集群模型，使它有可能为会话控制服务器，以实现可扩展性和动态伸缩。节点加入服务器集群时的一个问题是，当新节点接管调用状态时，查找负载会使其无法继续处理。因此，这种过载会降低服务可靠性。我们提出了两种方法来减少过载，并描述其属性。我们在一组实验中评估了这些方法。使用会话发起协议应用程序的评估表明，动态缩放是有效的，这表明该方法是有效的，在减少查找负载。
We discuss the dynamic scaling of distributed session control servers. Dynamic scaling refers to changing the system configuration by servers dynamically joining or leaving. In session control servers, availability and real-time processing must be guaranteed. Therefore, dynamic scaling must be achieved while ensuring these requirements. We propose a cluster model that makes it possible for session control servers to achieve both scalability and dynamic scaling. One problem when a node joins a server cluster is that the lookup load that occurs when the new node takes over call states makes it impossible to continue processing. Consequently, this overload can reduce service reliability. We propose two methods for reducing the overload and describe their properties. We evaluated the methods in a set of experiments. The evaluation using a Session Initiation Protocol application revealed that dynamic scaling was efficient, which indicates the methods are effective in reducing look-up load.
