TITLE:
Named Data Networking: Theory and Optimization for a New Internet Architecture

ABSTRACT: 

Emerging information-centric networking architectures, such as Named Data Networking (NDN), are currently changing the landscape networking research. Information-centric networking replaces the traditional client server model of communications with one based on the identity of data or content. This abstraction more accurately reflects how the Internet is primarily used today: instead of being concerned about communicating with specific nodes, end users are mainly interested in obtaining the data they want.

A primary goal of information-centric networking is the optimal utilization of both bandwidth and storage for efficient content distribution. This highlights the need for joint design of traffic engineering and caching strategies, in order to optimize network performance in view of both current traffic loads and future traffic demands. We present a systematic framework for joint dynamic interest request forwarding and dynamic cache placement and eviction, within the context of the NDN architecture. The framework employs a virtual control plane which operates on the user demand rate for data objects in the network, and an actual plane which handles Interest Packets and Data Packets. We develop distributed algorithms within the virtual plane to achieve network load balancing through dynamic forwarding and caching, there by maximizing the user demand rate that the NDN network can satisfy. Numerical experiments within a number of network settings demonstrate the superior performance of the resulting algorithms for the actual plane in terms of low user delay and high rate of cache hits. Joint work with Tracey Ho, Ying Cui, Michael Burd, Ran Liu, and Derek Leong.
