Internet Indirection Infrastructure

Attempts to generalize the Internet's point-to-point communication
abstraction to provide services like multicast, anycast, and mobility
have faced challenging technical problems and deployment barriers. To
ease the deployment of such services, this talk proposes an
overlay-based Internet Indirection Infrastructure i3 that offers a
rendezvous-based communication abstraction. Instead of explicitly
sending a packet to a destination, each packet is associated with an
identifier; this identifier is then used by the receiver to obtain
delivery of the packet. This level of indirection decouples the act of
sending from the act of receiving, and allows i3 to efficiently
support a wide variety of fundamental communication services. To
demonstrate the feasibility of this approach, we have designed and
built a prototype based on the Chord lookup system.
