摘要
服务发现是服务框架中联系服务消费者和服务提供者的重要环节。本文提出了一种面向服务提供者,以服务提供者为主体的服务发现机制。服务提供者维护一个本地缓存,为广告自己的服务提供途径,最终完成服务发现。它作为对已有服务发现机制的补充,可加快服务发现的速度,减少对远程发现服务器的访问次数,提高服务发现的成功概率。该机制还结合资源预约,根据服务消费者的访问频率,提供优先级服务和价格"优惠"。
The service discovery is the core technique of services framework, and the key part of services brokers that link service providers and service consumers in heterogeneous distributed systems. In the paper, a provider-oriented mechanism for discovering services is presented, which complements the existing discovering mechanisms. In order to speed up the discovery of services and reduce the access to servers, service providers utilize the content of local caches to advertise their services. Combining the resource reservation, this mechanism provides prior services and favorable price based on the frequency of access to this service provider for service consumers .
