2. What is ICN?
• Information-centric networking
1. Named data as a core principle
2. Caching integrated directly to Internet architecture
• Existing proprietary “ICN architectures”
• CDNs (Akamai), P2P applications (BitTorrent),
Google Global Cache,…
• Novel ICN architectures
• NetInf, NDN, Pub/Sub, DONA,…

3. Research question
1. What are the common value network roles of all
information-centric networking architectures?
2. How access ISPs (ANPs) can benefit from their
investment in information-centric networking?
Scope:
• Content delivery from content providers to
content consumers (e.g., video clips)
• NetInf as the studied ICN architecture (esp. Q2)

7. Step 1: ANP-provided content services
• Optimizing content delivery of
ANP-provided content services
(e.g. an IPTV service) inside the
ANP’s own network.
• Benefits for ANP
• Cost savings from more efficient
resource usage
• Better QoE for end users
• Challenges
– Limited benefits due to narrow scope Benefits

8. Step 2: Transparent caching
• Transparently caching content
originating from sources external
to the ANP.
• Benefits for ANP
• Benefits of Step 1
+ Savings in transit costs
• Challenges
– Content must be renamed à
decrease in efficiency

9. Step 3: Telco CDN
• Providing commercial CDN
services to content providers, i.e.,
monetizing the transparent
caching.
• Benefits for ANP
• Benefits of Step 2
+ Revenue from CDN service
• Challenges
– Small footprint compared to global
CPs

to

pure-play CDNs (Akamai, etc.)
– Network effects may create barriers

10. Step 4: Telco CDN with CDNi
• Extending the footprint of a Telco
CDN by interconnecting with other
(Telco) CDNs.
• Benefits for ANP
• Benefits of Step 3
+ Increased revenues through increased
footprint
+ Enables content-oriented peering and
traffic off-loading
• Challenges High
dependence
on
other
actors!
– High transaction/coordination costs
– CDNi standardization, esp. control plane

11. Step 5: Virtual CDN
• Outsourcing the customer
relationships with CPs to a virtual
CDN provider.
• Benefits for ANP
• Benefits of Step 4
+ Decrease in transaction costs with
other ANPs and CPs (but possibly
also in revenue margin)
+ Service becomes more attractive
• Challenges AIrac>veness
