We are receiving Antonio Carzaniga from USI Switzerland (Università della Svizzera Italiana). He will give a talk on Friday, April 29 at 14:00 in room Aurigny.
Title: Descriptors, Locators, Identifiers: Multi-Modal Addressing in the TagNet Information-Centric Networking Architecture
Abstract:
A truly information centric network is one where addresses are given by applications (users), not by the network. Application-defined addresses make applications easier to write and to deploy, but on the other and such addresses might not aggregate very well, which then limits the scalability of routing and forwarding. This is a crucial dilemma: how to architect a network so that applications can benefit from expressive and flexible addressing, and at the same time the network can scale. In this talk I will present the approach we took to solve this dilemma within the TagNet architecture. TagNet supports two distinct types of addresses at the network level: descriptors and locators. Descriptors are expressive and are fully application-defined, while locators are opaque network-level addresses. TagNet also distinguishes the role of identifiers, which play a fundamental role in caching and transport protocols, but not in routing and forwarding. With these three concepts, TagNet supports both push and pull communication, and, I will argue, it can do that with scalable routing and forwarding.
