Terabit routers and corresponding bandwidth consumption. Recent findings on the amount of router buffers made terabit electrical routers much less expensive and terabit optical routers, which may be even less expensive than electrical ones, viable. > When MPLS was new I remember being told by vendors that it was the only > way we could forward IPv4 at 10G line-rate. Go figure. When I proposed MPLS, it was over ATM and I already noticed and warned that MPLS (over ATM) inherently is about 10 times slower than IP routers and that MPLS over Ethernet is no better than IP routers.
