SMS云网关负载感知弹性伸缩控制算法

SMS短信网关（Short Message Service，SMS）具有并发量大、峰值高、难预测以及消耗资源量大的特点，如何保障系统高效、稳定运行一直是电信运营商致力解决的关键问题之一.本文提出了一种能够通过云计算平台动态资源控制能力，实现负载感知的弹性SMS云网关设计方案及弹性控制算法，提升了SMS短信网关服务质量目标保障效率，以及资源利用率.仿真环境下测试结果显示相比现有算法，弹性控制算法执行效率更高，集群规模随资源利用率抖动性更小.

Workload Aware Elastic-Scaling Algorithm for Short Message Service Cloud Gateway

SMS (Short Message Service) gateway has characteristics such as high concurrent capacity, high peaks, difficult to predict and high resources consumption. How to improve the system efficiency and stability has always been one of the key issues for the telecom operators to solve. This paper presents elastic SMS cloud gateway design and an elastic control algorithm, which can realize load sensing by dynamic resource control through the cloud computing platform, and improves SMS gateway service quality and the efficiency of resource utilization. Results of test on simulation environment show that, comparing with existing algorithms, the proposed algorithm is more efficient on scaling control, and has less resource utilization jitter on the condition of cluster size change.
