Maybe. For a single CPU, getting up to the state of the art, yes, it is a one shot fix. Mind you it's one shot that could add _years_ of service to the existing solution (a 10x speed up in CPU could give us 3+ years right there, if you believe doubling every year). I think there is real promise in SMP though. There are many SMP applications that scale near linearly, and I think properly designed routing can be one of them. If a linear SMP solution can be found then there is at least one way to scale the routing infrastructure to near infinate size simply for $$$'s. Even if a modest 4 processor design using the latest technology could only yeild a one time, 50x speed up that would give us 5+ years (again, doubling every year) of not worrying about that end of it to work on new protocols and the like. Heck, if you believe the predictions in 5 years we'll be out of address space and ASN's anyway, so a 'one shot' fix might take us to the end of the IPv4 days. -- Leo Bicknell - [email protected] Systems Engineer - Internetworking Engineer - CCIE 3440 Read TMBG List - [email protected], www.tmbg.org
