Re: [Softwires] MAP-E 1:1 for HA

[Ole Trøan <[e-mail]>]

> [Yuchi] Actually there is a 'binding' table on the AFTR, which maintains matching between v4 A+P and v6 A, and there's no 'mapping with address and port' in DS-Lite or Lw4over6 as in MAP. The main point here is not about the literal difference between 'binding' and 'mapping', but the difference between decoupling v4 & v6 and coupling v4 & v6.

let us assume we have a 1.1.1.0/24 for address sharing available with 256 ports per user.

in MAP 1:1 you'd have:
  1.1.1.1:01/40 -> 2001:db8::1
  1.1.1.1:02/40 -> 2001:db8::2
  1.1.1.1:03/40 -> 2001:db8::3
  .
  .
  .

  64K rules.

in MAP aggregated mode you have:
  1.1.1.0/24 -> 2001:db8:XXXX::/48

can you please show how the LW46 rules / binding /mapping whatever you call them look like for 1:1 mode?

cheers,
Ole
