Hi Rémi, all,
During the MAP discussion, we identified the following requirements:
R-4: MAP must allow service providers to define their own address
sharing ratio. MAP MUST NOT in particular restrict by design
the possible address sharing ratio; ideally 1:1 and 1:65536
should be supported. The mapping must at least support a
sharing ratio of 64, 1024 ports per end-user.
R-7: The MAP solution should support excluding the well known ports
0-1023.
R-8: It MUST be possible to assign well known ports to a CE.
The offset has been proposed as a flexible means to meet the requirements above.
Cheers,
Med
