Abstract: Logical scalable units (LSU) can be used within a single network data center to provide stateful scalability. However, LSUs are not suitable for operating across multiple network data centers in order to provide geographical redundancy in active-active scenarios while providing high availability. This is because the latencies associated with replicating full session information are unacceptably slow. An additional component in the LSU (known as an LSU Frontend) can be used to replicate a small subset of session information between LSUs. This subset of session information may be enough to enable LSUs to process requests in an acceptable way rather than outright failing. This may be particularly advantageous in scenarios where the requests relate to Voice over LTE calls, because outright failure is very perceivable to subscribers, and it causes resource leakage within the telecommunications network.

Abstract translation: 逻辑可扩展单元（LSU）可以在单个网络数据中心内使用，以提供有状态的可扩展性。 然而，LSU不适合跨多个网络数据中心运行，以便在主动活动场景中提供地理冗余，同时提供高可用性。 这是因为与复制完整会话信息相关的延迟速度是不可接受的。 LSU中的一个附加组件（称为LSU前端）可用于在LSU之间复制一小段会话信息。 会话信息的这个子集可能足以使LSU以可接受的方式处理请求，而不是完全失败。 在请求涉及LTE语音呼叫的情况下，这可能是特别有利的，因为直接故障对于用户来说是非常可感知的，并且它导致电信网络内的资源泄漏。
