摘要： 现有的以Web Service为主的SOA实现方案普遍存在占用通信带宽高、信息编码不适应窄带消息传递效率等问题，难以适应战术级作战部队高速机动、窄带网络、资源受限的作战特点。针对战术级作战信息系统在资源受限环境下实现服务化的需要，结合资源受限环境特点，分析现有负载均衡算法存在的不足，基于最小连接算法提出了一种动态权值分配算法。经过实验证明，该算法可有效提高资源受限下的高并发负载能力。

A software load balancing strategy in resource-constrained environment

Abstract： The existing SOA implementation solutions based on Web Service generally have problems such as high communication bandwidth occupation and inadequacy of information coding for narrow-band message transmission efficiency, and it is difficult to adapt to the operational characteristics of tactical combat troops such as high-speed maneuverability, narrow-band network, and resource-constrained operations. In response to the need for tactical combat information systems to be service-oriented in resource-constrained environments, the paper combines the characteristics of resource-constrained environments and analyzes existing load balancing algorithms. Aiming at the shortcomings of the existing algorithms，a dynamic weight allocation algorithm is proposed based on the minimum connection algorithm. Experimental results prove that the algorithm can effectively improve the high concurrent load capacity under resource constraints.
