Reading on "i3"

summary: The paper describes the Internet indirection infrastructure(i3) which offers a rendezvous-based communication abstraction. Basically, i3 decouples the act of sending from the act of receiving through using other identifier mechanism. Some communication primitives to support mobility, multicast and anycast are provided by i3. To demonstrate the feasibility of i3, the authors built an overlay network based on the Chord lookup system.

Reading "Middleboxes No longer Considered Harmful"

Summary:The middleboxes like NAT, firewalls and transparent caches are considered to violate the two tenets of the Internet architecture's original principles. To solve the problem, the authors present the delegation-oriented architecture(DOA). DOA uses the globally unambiguous identifier to specify every host in the Internet in which a DHT infrastructure is needed.
