RE: [RRG] yetAnotherProposal: AS-number forwarding

Title: yetAnotherProposal: AS-number forwarding

I have looked through the document but I think it is not exactly what I thought of.

I am just thinking of solution in which the backbone can use AS-number in the forwarding architecture. I does not mean that we need to change everything. It may be other reasons for larger changes of the routing architecture but I didn't consider it as necessary as a part of this proposal.

Hi Lar,

You can have a look at ENCAPS or HRA (http://www.huawei.com/file/download.do?f=3073), which are based on AS/LD-level routing.

Best wishes,

Hi,
I haven't had time to make a draft but I think it make sense for the discussion. However, I don't know if it already have been discussed so....

The proposal are simple: re-use AS-numbers into the forwarding of packets such that prefixes could be aggregated per AS. One simple implemetation is that the packets are tunneled and that the tunnel-address is associated to a AS-number. The AS-numbers can be assigned to the IP-addresses by DNS or by define a small address-prefix to AS-numbers.

Comments?
