一种基于动态带宽分配的企业服务总线模型

Enterprise Service Bus Model Based on Dynamic Bandwidth Allocation

现有的企业服务总线(ESB)系统在重载时会发生业务拥塞并导致服务质量下降。针对该问题,提出一种基于动态带宽分配的ESB模型。将总线上运行的各个业务流分为3种级别的业务类型。系统在运行时按业务类型优先级为业务流量动态分配带宽,以保证高优先级业务的带宽需求,减少拥塞的发生,提高系统的吞吐能力。实验结果证明了该模型的有效性。

Existing Enterprise Service Bus（ESB） systems may encounter congestion when they are overloaded,and the quality of services decreases rapidly.To solve the problem,this paper proposes an improved ESB model based on dynamic bandwidth allocation.The business flows run on the system are divided into three business types.The system can dynamically allocate the bandwidth at runtime according to their bandwidth demands respectively,so that the bandwidth of high priority business type can be guaranteed and the system throughputs are improved.Experimental results prove the effectiveness of the model.
