7. Why Something New? Limited Supply of Public Addresses NATs Prevent Sharing from the Edge Limited Name Resolution System Does not handle dynamic addresses Does not work in ad-hoc environments Does not lend itself to consumer use Inefficient Multipoint Communication Everyone Rewrites the Infrastructure Limited Supply of Public Addresses NATs Prevent Sharing from the Edge Limited Name Resolution System Does not handle dynamic addresses Does not work in ad-hoc environments Does not lend itself to consumer use Inefficient Multipoint Communication Everyone Rewrites the Infrastructure

8. Infrastructure Design Goals Secure, robust in face of failure/attack Scalable, from ad-hoc to the Internet Serverless, no central point of failure Self-tuning, adapts to constant change Self-repairing, automatically fixes itself Secure, robust in face of failure/attack Scalable, from ad-hoc to the Internet Serverless, no central point of failure Self-tuning, adapts to constant change Self-repairing, automatically fixes itself
