Re: How to multihome endusers [was: Cogent/Level 3 depeering]
Look into multi6 - which basically proposes new network layer above ip
but below tcp and that new layer would provide common end-point for system with multiple ip addresses.
A closer possibility right now is dns "multi-homing" based on incoming request ip, i.e. dns server would answer with one provider ip address if they are coming from cogent routed ip space and for another from l3 routed
ip space. This requires integration of bgp routing data with dns which has only been done by private implementations (I'm sure you all know who I mean) so far, but it would be a worthy project to do a open-source implementation of this technique if fragmentation of the internet continues to happen or becomes permanent.

Yes, indeed, I think it makes sense to multihome my humble enduser pc. Right now all I can get is aDSL and it does not matter what provider because they all use DTAG.DE infrastructure. Maybe cable will be choce. It is not as fast as aDSL at least not here and it will take another two or three years until they deploy it. If it does not get shot on site again by the regulation office or the cartell office again. So I will end up having a cable-modem speaking ethernet/PPPoE and an aDSL-modem speaking ethernet/ tcp/ip and DHCP. My ip adresses probably will be 84.167.xxx.xxx for aDSL and 24.xxx.xxx.xxx for the cable. I can talk to no-ip.com, they will allow a second ip for host_look("220.127.116.11","echnaton.serveftp.com","1420295334"). host_name("18.104.22.168","p54A7FCA6.dip.t-dialin.net"). Its entry will look a bit like this one: host_look("22.214.171.124","Kunden2.KONTENT.de","1364730419"). host_name("126.96.36.199","kunden2-1.kontent.de"). host_look("188.8.131.52","Kunden2.KONTENT.de","1364730420"). host_name("184.108.40.206","kunden2-2.kontent.de"). So I will end up with 3 names and 2 ip addresses for my humble host. Do I need BGP now or OSPF or can I rely on RIP. Do I need an AS number? How do I get it? Imagine not a fool like me is asking this but some 32K end users of DTAG.DE connected to a DSLAM at Franfurt/Main in germany. I guess the number of end users disconnected be Cogent and Level 3 is not much smaller. Asbestos parapluis opened. Shoot now!
