RFC4824

I found there was one April Fool RFC this year after 5 days delay. :)

http://www.ietf.org/rfc/rfc4824.txt

It's a new encapsulation of IP protocol on top of a very traditional link layer. :)
Here is an excerpt from the clause 3.5 of the RFC.

|3.5. Protocol Limitations
|
| Due to the physical characteristics of the transfer channel, bit
| error rates are expected to be in the range of 1e-3 (boy scout) to
| 1e-4 (professional sailor), and also depend a number of physical
| factors. Poor visibility due to weather conditions or lack of
| illumination (e.g., night time) can drastically increase the error
| rate.

Oh, well. I believe some African people can provide us extremely good quality transmission. Perhaps, error rate 1e-6 and extremely long distance? :o)

| IP-SFS provides no means to handle frame reordering or dual
| (multiple) frame reception. Thus, the protocol is not suitable in
| environments where interfaces are moving fast and/or when the path of
| light is long.

In Japan, about 1800 years ago, there was a genius who can listen to 7 people simultaneously, and so probably he can be a multiplexor among people using IP over SFS. :)
