Information-Centric Networking (ICN)
• Efficient content access without depending on server/content location – From IP address based communications to content ID based communications – From server based communications to content based communication
• Better performance to retrieve contents – From server distribution to content (or cache/repository) distribution – Content retrieval from closest cache
• Flexible data forwarding – Naturally support one-to-many or many-to-many transmission
• ICN proposals and projects – CCN/NDN (USA)
• In-network cache • Router extension
– NetInf → SEIL (EU) • Multi-layer overlay
– PSIRP → PURSUIT (EU) • Overlay + Rendezvous Point and Topology Manager

Content-Centric Networking (CCN)
• Content-Centric Networking (CCN) – V. Jacobson, et.al, “Networking Named Content”, Proc. ACM
CoNEXT 2009, December 2009, Rome, Italy. – From IP address based, end-to-end communications, to
content ID based, content-centric communications • Many users retrieve identical contents • Closest data (or copies) are not always on origin servers
– Content you want to obtain may be near you – Accessing origin servers is not the fundamental requirement
• CCNx: Prototype implementation – Available on: http://www.ccnx.org/

Functional Components for ICN • Naming
– Global unique content IDs – Content / cache resolver (or discovery mechanism)
• In-network cache – From network’s perspective:on-path caching / off-path caching – From application’s perspective:content type based algorithm
• Name-based routing – Proactive vs. reactive – Intra-domain vs. Inter-domain
• Transmission – From end-to-end reliability to cache transmission reliability – One-to-one / one-to-many / many-to-many
• Security – From server based authentication to content or cache based authentication – Cache protection / integrity
• Mobility
• Prototype implementation

Container-Based Unified Testbed • Container-Based Unified Testbed
– Design • Testbed node: VM (detailed later) • User node: Linux Container (LXC) based logical space
– Concept • ICN (basically, CCN/NDN based) experiments
– All required components (e.g., compiler, library, CCNx, etc.) for ICN experiments pre-installed/configured on VM
– Save hardware resources and operational costs (by eliminating install/set up common components per user)
» But not prohibit to install original components under user space • It supports two types of experiments
– User level experiment (e.g., I want to use CCNx, measure CCNx’s performance, develop some ICN applications on top of CCNx, etc.)
– Developer level experiment (e.g., I develop new routing daemon, so want to measure its performance over the testbed, etc.)
• Developers own “user node” having private IP address space – Possible to measure routing architecture

Requirements for Testbed Node
• Node requirement – PC or workstation
• VMware vShpere (ESXi) or Linux running VMware player • Intel i5 / i7 / Xeon, 8GB (or higher) memory
– VM • Ubuntu Server 12.04.3 LTS 64-bit or later
– Linux Kernel 3.8 – LXC 1.0 (alpha or later)
• Network requirement – Internet connectivity
• One (or more) global IP address – IPv6-only IF will work
– Private network • Virtual Ethernet (veth) • GRE tunnel
