论文摘要
中间箱越来越多地在地理分布的数据中心部署。在这些情况下，不同站点之间的WAN潜伏期可能会严重影响状态中间箱的性能。由于远程状态访问的高成本，在此类基础架构中的中间箱部署甚至可能变得不切实际。 我们介绍Constellation，这是Middlebox的GEO分布部署的框架。星座使用专门状态对象的异步复制来实现高性能和可扩展性。对我们实施的评估表明，与最先进的[80]相比，星座在较大范围的网络中提高了96倍的吞吐量。
Middleboxes are increasingly deployed across geographically distributed data centers. In these scenarios, the WAN latency between different sites can significantly impact the performance of stateful middleboxes. The deployment of middleboxes across such infrastructures can even become impractical due to the high cost of remote state accesses. We introduce Constellation, a framework for the geo distributed deployment of middleboxes. Constellation uses asynchronous replication of specialized state objects to achieve high performance and scalability. The evaluation of our implementation shows that, compared with the state-of-the-art [80], Constellation improves the throughput by a factor of 96 in wide area networks.
