Bonjour/Zeroconf Project
People
Gunho Lee and Junda Liu
Reason
The mobile nature of cellphones makes fixed or server-based network configuration unnecessary and difficult.
What is Bonjour/Zeroconf?
From wikipedia: Zeroconf or Zero Configuration Networking is a set of techniques that automatically create a usable IP network without configuration or special servers. In short:
- IP allocating without DHCP server
- Naming resolution without DNS server
- Service publishing/discovery without directory server
Bonjour (formerly Rendezvous)is Apple's version.
How?
- Looking up name-IP resolution by Multicast DNS
- Publish and find services by DNS Service Discovery
Major Implementations
From wikipedia:
Apple Bonjour
The most widely adopted Zeroconf solution is Bonjour (formerly Rendezvous) from Apple Inc., which uses multicast DNS and DNS Service Discovery. Apple changed its preferred Zeroconf technology from SLP to mDNS and DNS-SD between Mac OS 10.1 and 10.2, though SLP continues to be supported by Mac OS. Apple's mDNSResponder has interfaces for C and Java[9] and is available on BSD, Mac OS X, Linux, other POSIX based operating systems and Windows. The Windows downloads are available from Apple's website.
Avahi
Avahi is a Zeroconf implementation for Linux and BSDs. It implements IPv4LL, mDNS and DNS-SD. It is part of most Linux distributions, and is installed by default on some. If run in conjunction with nss-mdns it also offers host name resolution. Avahi also implements binary compatibility libraries that emulate Bonjour and the historic mDNS implementation Howl, so software made to use those implementations can also utilize Avahi through the emulation interfaces.
Avahi on maemo
Canola claims to support avahi, but unfortunately it is NOT open source. We also have problem in installing canola on N800.
