摘要: 为解决大规模企业信息系统中副本定位的目标节点服务质量问题,提出了一种基于多维度服务质量约束的副本定位方法。该方法把目标节点面向特定应用的多维度服务质量保障程度纳入副本定位计算,采用分层和对等的混合定位机制,在高效定位的同时有效避免了现有副本定位中目标节点服务质量无保障的风险。给出了大规模企业信息系统覆盖网模型、基于多维度服务质量约束的副本定位方法的定义和算法及与之相关的应用层路由算法和副本发布算法。通过在某企业中的应用,验证了所提方法的有效性。

Abstract: To achieve high Quality of Service(QoS) of destination node in Replica Location (RL) over Large Scale Enterprise Information System (LSEIS), a novel RL with Multidimensional QoS (MQoSRL) was put forward. MQoSRL offered a mechanism to achieve high efficiency and avoid risking bad QoS for a given application in existing RL. It was implemented by considering the guarantee degree of destination node for a special application with multidimensional QoS constraints and employing hybrid location mechanism based on layered and peer to peer. The overlay network model about LSEIS was described and the definition of MQoSRL was provided. The sub-arithmetic about MQoSRL and other correlative algorithms, such as replica publishing and application layer routing, were described in detail. Effectiveness of this method was verified by using in an enterprise.

Key words: enterprise information system, replica location, quality of service, application layer routing
