Internet Indirection Infrastructure

This paper is quite interesting, introducing an overlay on top of the current network architecture to create an abstraction that allows for more efficient implementation of different services, including multicast, or mobile networks. This overlay network utilizes a rendezvous based communication method which isolates senders and receivers so that the packet a sender is sending can be received by different receivers, or processed and routed differently depending on the receiver's request. This is done by unique id's on the sender and receiver side which is matched to ensure the transmission of the data. The underlying implementation of the overlay is using the chord lookup like the previous paper.

I think the idea of this is definitely very interesting, because it allows for abstraction on top of existing network solutions in which can easily implement several different services. However, despite the security section mentioned in the paper, it still seems like using the id for authentication of receiving messages might be really susceptible to eaves dropping. But it is true that the current Internet architecture is no better. One question i had is how the chord lookup table will affect the normal routing of the packets, since it seems like it's more work to have to go through the lookup table just to send a packet. But overall, i liked the paper, and it seemed like a good idea. Since this paper is from 2002, are there are any active deployment of it?
