Dear Murakami-San, I'm very concerned about your work on MAP-T. I've read the draft-mdt-softwire-map-translation-01, and I'm confused with some statements in the draft. Questions are as follows:
1. In section 7.4, there is a statement saying "Otherwise, the IPv6 destination address (IPv4-translatable address) MUST be derived from the received IPv4 destination address per DMR." I'm wondering if the IPv4-translatable address here should be IPv4-converted address. 2. In section 7.5, the expressions of "IPv6-converted address" and "IPv6-translatable address" confused me. I am wondering if the "IPv6-converted address" should be "IPv4-converted address"or not, and if the "IPv6-translatable address" should be "IPv4-translatable address". Here is are two pictures which depict my understanding of the draft. Pic 1. Upstream from CE to BR: CE BR IPv4 src BMR IPv6 src (IPv4-translatable) FMR IPv4 src --------------> --------------> IPv4 dst FMR, DMR IPv6 dst (IPv4-converted) DMR IPv4 dst Pic 2. Downstream from BR to CE: CE BR IPv4 src FMR, DMR IPv6 src (IPv4-converted) DMR IPv4 src <-------------- <-------------- IPv4 dst BMR IPv6 dst (IPv4-translatable) FMR IPv4 dst I'm not so sure if my understanding is right. Please correct me if there is any mistake I've made. Thank you very much! Best regards! Yuchi Chen
