Hi Tetsuya, Thank you very much to provide your test results. Please see inline.
Agreed. Some of traditional CPEs might not be able to handle a bunch of NAT > sessions due to the resource limitation such as memory, cpu, etc. From the > implementation point of view, I think the required resources for 4rd mapping > rule is smaller than the resources for NAT session because usually NAT > session contains many information. > > [Qiong]: Basically agree that '4rd mapping rule is smaller than the resources for NAT session', but 4rd CEs would still do NAPT similar to traditional CPE's NAPT (with restricted port range), right ? > Did you asked about the forwarding performance? We used netbsd running on > arm core cpu (400MHz). The accrual ratio of the latency is just 2 to 5 % > under 4rd environment. > [Qiong]: Well, this latency is acceptable to me. > > Thanks Qiong Sun
