MotivationMotivation What is the value of:
end-2-end architecture Efficient centralized Vs flexible distributed architectures Network Neutrality
It depends on market uncertainty! It is important to know what users want
If you know and others don’t, then you can win big if market uncertainty is high

What are traditional methodologies good for If I know what users want
What if we don’t understand what users want? What services, with what features? How much will they pay for them? Does uncertainty imply more value to network neutrality

Why “real options”Why “real options”
Options theory models uncertainty, flexibility and choice Options illustrate how to limit risk, without capping gain –
a good design principle Real options extends the theory of options to non-financial
assets Building IT infrastructure, modularity in computer systems,
modularity and staged development of IT standards Real options illustrate when flexibility is worth more than
efficiency

Management Structure and Experimentation
Management Structure and Experimentation
What is Experimentation Features in devices and services
Distributed management structure is easy to experiment with Don’t need permission Don’t need to change network infrastructure A bad experiment only affects a few users
Centralized management makes experimentation hard Need to change network infrastructure Need to ask permission Many users affected with bad experiment

Market UncertaintyMarket Uncertainty
Market uncertainty is the inability to predict what uses want
How to measure it: Tushman and MacCormack Tushman: how well have historical predictions about
market been MacCormack: Emergence of dominate design Gaynor and Bradner: measure changes in standards,
stable feature sets The value of the best of many experiments is
related to the market uncertainty

When market uncertainty is high)
Best of Many Attempts to Meet the Market(When is experimentation worthwhile?
When market uncertainty is high)
Each attempt is an implementation with a particular feature set Extreme order statistics – Value of best of many attempts High market uncertainty => someone wins big (maybe you), low market
uncertainty => no big winners because its easy to satisfy users

DefinitionsDefinitions MU = Market uncertainty X is a random variable denoting the value of one choice the user has for a
service E(X) = V, s.d(X) = MU
CP(A) cost to provide the service with architecture A F – is for flexible and expensive architecture C – is for controlled and efficient architecture
VS(A) net value of service provided with A Assumptions – flexible networks allow users more choices, but cost more
CP(F) > CP(C) – we call this the Business and Technical Advantages of controlled (centralized) architecture
BTA = CP(F) - CP(C)

ModelModel
Value of controlled architecture VS(C) = V - CP(C) We assume only one choice for users
Value of flexible architecture at the ed VS(F) = V - CP(F) + Q(x)*MU We assume x choices for users
Flexible networks are more valuable when VS(F) - VS(C) > 0 Which implies: Q(y)*MU > BTA This means the value of experimentation is greater then the
advantages of controlled/centralized architecture
Value of controlled architecture VS(C) = V - CP(C) We assume only one choice for users
Value of flexible architecture at the ed VS(F) = V - CP(F) + Q(x)*MU We assume x choices for users

Network NeutralityNetwork Neutrality
Users can use their bandwidth for anything they want, in any way they want (Tim Berners Lee)
The network does not bias traffic to and from users based on its content, source, or destination
Does not bias traffic to the disadvantage of the end user
A network service provider offering VoIP can not give lower QoS to a competing VoIP service provider in a neutral network

Openness in 700MHz SpectrumOpenness in 700MHz Spectrum Google wanted in the 700MHz C block:
“Open applications: consumers should be able to download and utilize any software applications, content, or services they desire;
Open devices: consumers should be able to utilize a handheld communications device with whatever wireless network they prefer;
Open services: third parties (resellers) should be able to acquire wireless services from a 700 MHz licensee on a wholesale basis, based on reasonably nondiscriminatory commercial terms; and
Open networks: third parties (like internet service providers) should be able to interconnect at a technically feasible point in a 700 MHz licensee's wireless network. “ - http://googlepublicpolicy.blogspot.com/2007/07/promise-of-open-platforms-in-upcoming.html
FCC wants: Any device and application
Carriers want their devices, applications, services, and no wholesale network pricing!

Architecture Vs NeutralityArchitecture Vs Neutrality
Centralized networks such as the PSTN and Cellular are easy to control and do not promote network neutrality But, then can be neutral if the central manager allows it
Distributed networks such as the Internet promote neutral network But, it is possible for ISPs to bias traffic
The PSTN has grown more distributed, and the Internet has become more centralized

Neutrality Model - Assumptions and Notation
Neutrality Model - Assumptions and Notation
A neutral network has a single provider for all transport, content, and services
A non-neutral network has a single transport provider and many content/service providers
The Transport provider offers a service bundle (voice, video, email) including transport and its pick of content/services
The costs of a neutral and non-neutral network is the same to build and manage We believe the non-neutral network is more expensive, which
strengthens our argument The network has N users

Neutrality ModelNeutrality Model R(SCP) = total revenue from customers for services and content to the provider(s)
Sum of revenue for all non-transport services and content. R(TSP) = total revenue from customers for transport service to the transport
provider We assume the value of R(TSP) is proportional to the value of R(SCP), the more the
services and content is worth, the more the pathway to these services and content is valued by users
Let “P” be this proportionality constant, then: R(TSP) = “P” * R(SCP)
This is similar to metered pricing that charges by byte, however in this case the “network tax” is related to the value of the service to the user, not the network resources consumed by the service
In this simple model the total value of the network is just R(SCP) + R(TSP) V(Total) = R(SCP) * (1 + “P”) – Total value of the network infrastructure.
V(Total) has two components, the transport service (i.e. R(SCP) * “P”) and the service component (i.e. R(SCP))
R(SCP) = total revenue from customers for services and content to the provider(s) Sum of revenue for all non-transport services and content.

AP = $100 - The average price users are willing to pay for a service.
SD = $100 – The standard deviation of the distribution describing the value of services to users.
“N” = 1000 – Number of potential users “P” = .50 - Fraction of revenue for services that a user
pays for transport – network tax. X = 100 – Number of choices a user has for services. U(100) is rounded to 2 standard deviations above AP, thus
U(100) = $300.

ConclusionConclusion Real options provide a way to model uncertainty Our model illustrates the tradeoffs between: market
uncertainty, the advantages of control and central management, and the number of experiments
It shows that neutral networks generate more total revenue (transport + services) in uncertain markets
The question changes from neutrality or not, to how to split the bigger pie
