[Noisebridge-discuss] Linux Ethernet-over-IP tunnels

[Rodney Thayer]

ok someone else already used "sexy" and "ethernet frame" in the same 
post so I can do it too ;-)

I believe another sexy way to do this is to run MPLS and let the kernel 
pump the frames over IP just like an MPLS cloud would.  I've not done 
this.  I just checked and there was (as of Fedora 8...) some MPLS Linux 
kernel work.

P.s. one could also be cruder and write a PCAP-enabled application that 
wraps frames in your own format and blurts them over a wire to the other 
end.  802.2-over-http-over-tcp-over-ipv4 via a PCAP-aware perl script 
hitting a CGI on an instance of Apache HTTPD at the other end?  That'd 
be ghetto but it might work...
