Yes a very big unless. Multi-core processors are already available that would make very large BGP convergence possible. Change the algorithm as well and perhaps add some multi-threading to it and it's even better.

Not necessarily. BGP convergence is strongly dependent on memory bandwidth and multiple cores do not increase that.

Sun just released the T2 chip, claimed 60GB/s memory bandwidth, on- board 10GbE interface etc. Pricing under $1000 for an 8-core chip with 64 "threads". Cordially Patrick Giagnocavo patrick@zill.net
