几个服务发现协议部署在局域网中，允许用户被告知他们附近的服务。然而，这些局域发现协议不能将服务暴露给远程用户。本文提出了一种基于P2P的命名系统，以确保广域服务发现之间的通信设备和服务往往位于远程。命名系统通过为广域环境中的服务定义统一的命名方案来实现发现协议的透明性。命名系统具有可扩展的P2P架构，并集成了通知服务，通知用户有关的服务和他们的移动性。作为一个应用程序的用例，这项工作扩展UPnP，一个本地区域和即插即用的服务发现协议，广域服务发现系统使用建议的基于P2P的中间件。
Several service discovery protocols are deployed in local-area networks allowing users to be informed about the services in their vicinities. However, these local-area discovery protocols are incapable of exposing the services to remote users. This paper proposes a P2P-based naming system to ensure wide-area service discovery for communications between devices and services often remotely located. The naming system enables the transparency of the discovery protocols by defining a unified naming scheme for services in wide-area environments. The naming system has a scalable P2P architecture and integrates a notification service which informs subscribers about the services and their mobility. As an application use case, this work extends UPnP, a local-area and plug-and-play service discovery protocol, to a wide-area service discovery system using the proposed P2P-based middleware.
