I agree with Joseph that these should be combined and published. As for dealing with conflicting M&O, just XOR the received set. When the state changes from 1 to 0 (actually in either direction), after a random delay re-query DHCP to verify the lease time/config information. In a managed configur

Hi, Used link-layer does have an impact: on cellular networks the link-layer is nowadays most often opened on-demand (i.e. when an application starts), or quickly reopened e.g. if network connection is temporarily lost for any reason. In the future always-on connectivity becomes more commonplac

Hi Fred, How do you see RANGER fitting into the requirements for carriers to supply IP support (v4/v6) to mobile devices? Especially requirements that are similar to the enterprise ones that you describe? Eric Templin, Fred L writes: This message is to introduce a new Internet-Draft title
