Hi there -
Actually, BGP supports (a) when the packet is near the recipient, (b) when the packet is near the sender and (d) [ISP traffic engineering] when the packet is in between. Everybody gets to tweak the path.
Certainly. I was focussing on the part near the recipient, though: the selection of an edge network's ingress link. This part is where BGP-based traffic engineering supports (a) and only (a). - Christian -- to unsubscribe send a message to rrg-request@psg.com with the word 'unsubscribe' in a single line as the message text body. archive: <http://psg.com/lists/rrg/> & ftp://psg.com/pub/lists/rrg
