The principle is good, details are not: - only switched (giga) Ethernets were used (no wireless) - the PCP should get double arrow - all SD-B4s run a PCP/NAT-PMP/UPnP-GID-v1+v2 server (in fact they have the same kind of softwares, the laptop just offers more tools, 1 times larger

With the checksum re-computed, as per the rfc6145 option, translated IPv6 packets would get the right checksum. With 4rd-u so far I see no such option. -Woj. On 23 March 2012 14:55, Rémi Després despres.r...@laposte.net wrote: Hi, Wojciech, Are you suggesting that T would work with IPv4

[Softwires] questions about 4rd-u

2012-03-26 Thread Jiang Dong
Hi, Remi, I get some questions about the 4rd-u draft. 1) The tunnel packet defined in your draft includes an IPv6 header followed by a IPv6 fragmentation. Can this packet be defined as a tunnel packet or a translation packet or neither or both? Since this is not the traditional tunneling

[Softwires] Comments about 6rd MIB

2012-03-26 Thread Jiang Dong
Hi, authors of 6rd MIB, I get some comments about 6rd MIB draft. 1) You mentioned the tunnelIfXTable in section 5.2. I think it is a good idea to extend the tunnel MIB, some scenario cannot be included in RFC4087, such as point to multi-point tunnel like softwire mesh. 2) It seems you miss

In your previous mail you wrote: Today, if a user generates a packet using an illegal IPv4 source address, what would we do? We could drop the packet silently by doing source-verify. So, tomorrow if a user use illegal port, IMHO AFTR should drop the packet silently. = it is a bit

Maoke, I like your analog of horse, donkey, and donkorse! and fully agree with you. People know what kind of situation horse and donkey can help to solve the problem. People do not want unknown donkorse because it creates more problem rather than solving specific problem. Kevin Yin

Hi, Remi, This is beyond the charter of softwire WG, changing IPv6 address format needs much broad discussion in IETF community to understand its impact first, before we should even discuss if it is valid to design something like this in softwire. Have you done that ? Best Regards, Kevin Yin

Dear Maoke, Thanks for clarifying what you meant. I now understand that you were referring to applications that might require IPv4 dialogue between one link apart nodes. Whether this is a real use case in the MAP-4rd context remains however to be seen. Here are my immediate comments: a) This
