Content Based Traffic Engineering in Software Defined Information Centric Networks
This paper describes a content centric network architecture which uses
software defined networking principles to implement efficient metadata driven
services by extracting content metadata at the network layer. The ability to
access content metadata transparently enables a number of new services in the
network. Specific examples discussed here include: a metadata driven traffic
engineering scheme which uses prior knowledge of content length to optimize
content delivery, a metadata driven content firewall which is more resilient
than traditional firewalls and differentiated treatment of content based on the
type of content being accessed. A detailed outline of an implementation of the
proposed architecture is presented along with some basic evaluation
The Road Ahead for Networking: A Survey on ICN-IP Coexistence Solutions
In recent years, the current Internet has experienced an unexpected paradigm
shift in the usage model, which has pushed researchers towards the design of
the Information-Centric Networking (ICN) paradigm as a possible replacement of
the existing architecture. Even though both Academia and Industry have
investigated the feasibility and effectiveness of ICN, achieving the complete
replacement of the Internet Protocol (IP) is a challenging task.
Some research groups have already addressed the coexistence by designing
their own architectures, but none of those is the final solution to move
towards the future Internet considering the unaltered state of the networking.
To design such architecture, the research community needs now a comprehensive
overview of the existing solutions that have so far addressed the coexistence.
The purpose of this paper is to reach this goal by providing the first
comprehensive survey and classification of the coexistence architectures
according to their features (i.e., deployment approach, deployment scenarios,
addressed coexistence requirements and architecture or technology used) and
evaluation parameters (i.e., challenges emerging during the deployment and the
runtime behaviour of an architecture). We believe that this paper will finally
fill the gap required for moving towards the design of the final coexistence
architecture.Comment: 23 pages, 16 figures, 3 table
