Future Internet Networks

More and more devices connected, more and more service providers, more and more content consumed… leading to more and more data traffic! In this seminar, experts, network equipment providers and operators have drawn on how the future Internet networks may look like through the analysis of the major emerging trends by 2025 : SDN (Software Defined Network), NFV (Network Function Virtualization), 5G, M2M (Machine to Machine) and Internet of Things have been at the center of discussions.

Introducing a new era of network infrastructure with SDN and network virtualization

The first round table provided hot discussions on SDN and NFV with speakers from telco, from network solutions and from network equipment manufacturer. These are the questions asked to the speakers:

When future network will be rolled out?

• Network is the next step in the virtualization trend following servers and storage. SDN and NFV require important changes, proof of concept, and trials before a roll out. Such steps require years.
• Moreover, as Ryan SHUTTLEWORTH from Verizon said “SDN and NFV are not mature technologies yet.” SDN is currently rolled out at the scale of a datacenter and not really at a telco network level.

What are the main drivers?

• Savings is the first obvious driver of such technologies, but generated new revenues are also an important benefit to consider. The agility and the simplification of operations are also strong promises of SDN.
• Besides, the ability to make a link between cloud services (virtualized servers) and the virtualized network should be an interesting benefit.

What is the impact on the ecosystem?

• On the supplier side, new suppliers are expected to come. Moreover, the elasticity of the infrastructures created by SDN and NFV can lead to new business models. It will also enable a new level of developers.
• In general, changes related to the implementation of these new networks will have to be managed internally by both equipment vendors and telcos. Those who manage correctly IT, network and cloud will be able to leverage a strong competitive advantage.

Another aspect has been introduced then, related to content distribution: the future of Content Delivery Networks, illustrated by Ahmet OZALP from Akamai. He presented 11 predictions for this future. Among these predictions:

• As traffic will grow exponentially, CDN should be used also more and more in order to reduce the overall traffic. In 2012, CDN traffic was 53% of all consumer traffic and should be up to 65% in 2017 according to Akamai.
• Connected devices will bring complexity to deliver services correctly: especially Connected TVs and Home consoles. All devices support various protocols and formats that has to be handled to deliver services.
• CDN architectures should evolve. In the future the content will be closer to the end-user, providing cache servers closer to the access network, as in the figure below from Akamai presentation.

• The cooperation between CDN and telcos will be stronger in the future in order to reduce the traffic. In addition, CDN should enhance OTT video quality, exceeding traditional TV quality level. CDN services should become more and more cost effective. In the end, CDN market will have a healthy growth.

The focus of this seminar then shift to Franck BOUETARD from Ericsson with a presentation of Marc Plaszczynski, from Thales Alenia Space.

• Regarding the evolution of satellites, Mr. Plaszczynski mentioned that “Satellite Systems have enhanced their broadcast capabilities with high-value, integrated, flexible and interactive new Satellite solutions”.
• In addition, Satellite systems are adapting to support efficiently the Future Internet Networks evolution with hybrid end-to-end Systems. Satellite systems have also made improvements a comprehensive set of skills and solutions to foresee the unforeseeable.

Franck BOUETARD from Ericsson then presented his view on drivers of the future networks and 5G. He especially mentioned the Metis Consortium, 29 partners led by Ericsson, looking to 5G for after 2020. There are 5 things to address as mentioned in the figure below. Drivers for future networks are mobility, video traffic, 50 billion connected devices, high speed access, Network cloud and QoS.

Tailoring future networks for the Internet of Things

Samuel Ropert from IDATE then introduced the second round table about Internet of Things :

• M2M is the first step of IoT. It is especially a combination of various value chains: electronic, telecom, computing, and machines themselves
• IDATE forecast; in 2017, M2M SIM cards represent
- 5,9% of all SIM cards (human and machine) worldwide
- 14% of all SIM cards in Europe
• BUT In 2017, M2M connectivity revenues represent
- 1.3% of mobile revenues worldwide

The main topics discussed during this round table are as followed:

Technologies Issues

• Regarding communication technologies, M2M players mentioned that they are focusing particularly on 2G, low energy equipment, low bandwidth, as low cost is fine for objects. 4G is 7 time more expensive than 2G. Working on special 4G for machines require standardization, expected for 2017-18. Use cases are also important. For cars for example, LTE may make sense, even if expensive. Another example is video surveillance that is expensive but 4G brings quality.
• Regarding security issues, wireless is secure. The issue is protecting user privacy. For instance cars: driving too fast, location … can be obtained through M2M, but how do we protect privacy? The EU is trying to tackle the problem, but it all comes down to privacy, how is it guaranteed?

Need for standardization?

• M2M is everything but standardized. A lot of use cases are emerging, but no standards. Gathering the right data is difficult, accurately, and analyzing it. It is not a problem of big (too much) data, but accuracy.
• There is maybe a need for hierarchy of objects for standardization. In the last 5 years: it has been pushed by regulation. Ehealth seems to be most promising growth.

What role will startups play?

• They can play active role in creating applications.

Nicolas Demassieux from Orange concluded the session with a longer perspective vision on future networks. He especially mentioned that SDN can be compared to PC computer architecture with hardware managed by software, managed by the user. More generally, the current concept of communication infrastructures will be transformed to services distributed across “device + Network + Cloud”.
