Definitions
●Internet Neutrality:
Internet users are entitled to service that does not discriminate on
the basis of source, destination, or ownership of Internet traffic.
●
CSP: Cloud Service Provider
●
CCS: Cloud Computing Services
●ISP: Internet Service Provider

General Problem Description
●Internet-Neutrality is under threat
●
From 2 sides:
●
Politics
●Business
●
No consensus on where Internet Neutrality is
needed
Deregulationists point of view
Internet Neutrality causes rising bandwidth
demand
● Content Providers profit from more customers → pushing bandwidth needs ● Existing customers → no incentive for saving bandwidth
● Unlimited models e.g. Netflix
Deregulationists point of view
Revenue split between ISPs and Content
Provider is unfair
● Commodity vs. higher margin business
Deregulationists point of view
QoS fosters innovation
● Today: best effort ● Possibilities:
● Development on technical side ● Development of business models
Business Models conflicting with
Internet Neutrality
Differentiation through service quality
● Service quality can mean different things:
● Latency
● Throughput (absolute / relative) ● Availability
Business Models conflicting with
Internet Neutrality
Restricting access to own customers
Business Models conflicting with
Internet Neutrality
Favour own service
● Degradation of traffic
● Up to not usable anymore
● Example: Comcast degraded some traffic, especially P2P
● Skype was affected
● Outcome:
Bandwidth consumption of CCS
General considerations
● Type of computing → how many nodes ● Data / computation ratio
● Incentive to reduce demand: bandwidth costs
● ISP ● CSP
Bandwidth consumption of CCS
IaaS
● Most broad approach in Cloud Computing ● Potentially highest bandwidth demand
PaaS
● Web hosting
Bandwidth consumption of CCS
SaaS
● Access through web browser → data generated by human interactions ● Optimization from CSP-side
Bandwidth consumption of CCS
Comparison to consumer-focused services
● Focus of deregulationists criticism ● Example Netflix
Conclusions
Main points of threats
● Bandwidth demand is rising too fast → who is “responsible”
Conclusions
Why CCS is not enough to threat Internet
Neutrality
● Business use cases less data intense than consumer demand ● Focus on other services
● Bandwidth not that scarce

Discussion:
●
Has Internet Neutrality a negative impact on
innovation?
→ on network technology?
→ on business models?
Discussion:
●
Do you believe in the argument of “scarce bandwidth”
Discussion:
●
Is there a need for regulation by law to enforce
Discussion:
●
Can CCS even save bandwidth through intelligent
