avahi-daemon是一种Linux操作系统上运行在客户机上实施查找基于网络的Zeroconf service的服务守护进程。

该服务可以为Zeroconf网络实现DNS服务发现及DNS组播规范。

用户程序通过Linux D-Bus信息传递接收发现到网络服务和资源的通知。

该守护进程配合缓存用户程序的答复，以帮助减少因答复而产生的网络流量。

详见以下描述：  Description

The avahi-daemon Linux service runs on client machines to perform network-based Zeroconf service discovery. Avahi is an implementation of the DNS Service Discovery and Multicast DNS specifications for Zeroconf Networking.  User applications receive notice of discovered network services and resources using the Linux D-Bus message passing. The daemon coordinates application efforts in caching replies, helping minimize network traffic. Avahi provides a set of language bindings, including Python and Mono.  Because of its modularized architecture, Avahi is already integrated in major desktop components like GNOME's Virtual File System or KDE's input/output architecture. Refer http://avahi.org/ for further specifications. The avahi RPM package provides the /usr/sbin/avahi-daemon daemon and its configuration files.
