Dave Clark, MIT: Jumping the Open Barrier—Innovation Opportunities for
Infrastructure Companies


The peril of the open interface: Why should I spend a lot of money to enable someone else to
make a lot of money.
Introduction to the challenge of open and how
Ashish Gupta, Huawei
 The challenge is that the customers we have targeted are realizing that they serve as just the
pipe, and this is challenging their economics.
 A lot of Huawei’s work has been to help their customers solve the challenge of maintaining
service to their consumers despite the exponentially growing demand for data
 Huawei’s intent is to take data and make it applicable to the real world, to solving telephony
challenges
Roberto Sarraco, Telecom Italia
 The last two years have seen a big debate within TI (Telecom Italia) regarding OTT
o One side argues that they add too much traffic and are making money off of the TI
network
o One side says that if it wasn’t for the OTT, TI wouldn’t be as successful as we’ve been
 One of the lessons that TI has learned is that the service area is no longer a strategic area for the
company
 There are further debates within the company regarding how to use QOS measures
 EIT was created to invest money in focusing on bringing research and innovation out of academia
and into the field.
o A lab has been created to test future telecom technologies
o It allows the testing of questions such as ‘if we have unlimited bandwidth, what does it
enable us to do?’
 EIT is a trial to gain field experience on the future of communication technologies
Rich Woundy, Comcast
 Exploring home security and home automation
 Home security fits well with Comcast’s abilities – they have the trucks and people to go out to
homes and install security techs
 Control panel touch screen acts as the center of the home automation interaction
o Zigbee used for intra-house comm.
o Cameras in house run over wifi to accommodate higher bandwidth
 Control center hotline managed by someone besides Comcast
 Comcast strives to define many open interfaces between controlled and home automation
devices
Bruce Davie, Cisco
 Interconnection of CDNs
 The vision is analogous to the interconnection of ISPs that fostered early internet growth
 The CDN landscape is similar to the landscape of packet networks in the early 70’s – before there
was a well-integrated internet.
 Cisco has begun a trial with Orange, Coblitz for CDN interconnection
Jan Kok, NSN
 ‘How can the CSP rediscover their buttons for sustainable revenues’ is a major question.

Q&A


The strengths of the Telco are their managed QoS and security as well as flexible carrier charging
However, Smaller addressable markets and high service deployment costs are posing challenges
To Bruce, why can’t we have two CDN approaches – one bigger, one smaller?
o It’s a possibility, but I wonder if the smaller CDNs can be interconnected such that they
are actually useful.
Are you designing any money routing protocols for an interconnected CDN network?
o It seems like we’re reproducing the same mistakes as made during the design of the
internet, in that we don’t necessarily focus on designing money routing protocols
To Roberto, could you expand a bit on ICT?
o By expanding ICT into more segments, you can actually improve efficiency in several
regards. Similarly to how in the early days of the internet, the money flowing through
the internet wasn’t effectively captured, there are presently opportunities for increasing
efficiency.
When talking about entering home security, how do you suggest you’ll optimize another industry
when it is already difficult to optimize your own?
o We don’t claim we’ll optimize other industries, but we can leverage the skills we do
already have to play some role in these other industries.
