Describe the problem of unbound names in multicast navigation. What is implied by the installation of a server for responding to lookups of unbound names?
What will be an ideal response?
In multicast navigation, a client multicasts a name to a group of servers for resolution. If a server can resolve the name, it replies to the client. To minimise messages, a server that cannot resolve the name does not respond. However if no server can resolve the name – the name is unbound – then the client will be greeted with silence.
It must re-send the request, in case it was dropped. The client cannot distinguish this case from that of the failure of a server that can resolve the name.
