End-User Mapping: Next Generation Request Routing for Content Delivery


While traditional mapping systems identify a client using the IP of its name server, we describe our experience in building and rolling out a novel system called end-user mapping that identifies the client directly by using a prefix of the client’s IP address.

Read this paper to learn how end-user mapping provides significant performance benefits for clients who use public resolvers, including:

  • Eightfold decrease in mapping distance
  • Twofold decrease in RTT and content download time
  • 30% improvement in Time To First Byte
