Re: [RRG] Why delaying initial packets matters



David -

A pull system can potentially provide for much higher rates of change
than a push system.  As I believe has been mentioned in the past, a
pull system (if augmented by forwarding) could even be used for
mobility.

Yes.  The advantage of a reactive (pull) mapping system over a proactive
(push) one is that the former can provide tailored responses, such as
responses that indicate which in a list of locators is currently
preferred.  It thus provides a tool for traffic engineering of incoming
packets.  This is an advantage, albeit a small one given that a locator
can be changed in-band within a round-trip after mapping resolution.

Regarding mobility support of a reactive mapping system:  It would work
for local mobility within an edge network.  But not for global mobility.
