  7. MSD Server Base Algorithm

  8. mDNS URL Design • In mDNS, sessions can be accessed directly if creator successfully registers keyword with it’s domain’s URS server. • mDNS URL syntax • <protocol>://<domain URL>/<URS Keyword> • Protocol could be http or any valid protocol type • Domain URL helps resolve MSD server located in the creator domain, it begins with mcast. • Example mDNS URL could be • http://mcast.cise.ufl.edu/gators • This would refer to multicast session hosted under cise domain with keyword ‘gators’ registered with cise URS server. • What is returned is the session’s details. mDNS capable browser could then launch an appropriate plug-in to display the multicast contents sent on that channel.
