When were you engaged for the first time with networking and what memories do you have from it?
My first experiences in telecommunications and connectivity were with TDM technology (Time Division Multiplexing) and SDH (Synchronous Digital Hierarchy) and ATM technology. ATM is in the meantime in fact completely outdated. Connectivity speeds were much lower than today and the transport was based on static channels that connected point-to-point locations.
We all thought traffic between two points happened in predefined, static, and pre-reserved containers. That is not the case anymore.
Which technologies were in use and what has changed since then?
The migration to packet based networking (switched IP) changed the landscape of solutions available for connectivity, and new technologies took the center stage: IP Routing, MPLS, MPLS-TP and others. In parallel the speed that was made available to the end user increased dramatically with new technologies that evolved and continue to evolve which allow high speed connectivity over copper: ADSL, ADSL2, ADSL2+, VDSL, VDSL2, G.Fast; and network architectures that have enabled fiber glass infrastructure becoming available to end users: FTTB, FTTS, FTTH.
An additional technology that has changed the telecom world dramatically is of course mobile. Due to the improvements in available bandwidth and capabilities, this technology plays an increasingly important role within the range of possibilities available for connectivity. 5G will further change this landscape and may even fundamentally change the way we perceive mobile interconnectivity.
When did you specialize in networking and why?
I entered the world of telecommunications in 1999, and it has been an exciting ride. I had the chance to be involved in the development of various products used for networking and access, for example MPLS-TP, ADSL2, and FTTH. This gave me the chance to work closely with telco operators as well as large Enterprise customers building their own private networks.
I have experienced and embraced the development of the technologies that keep us connected and also seen how it has changed our lives. In the last 10 years, the possibilities in telecommunications have exploded – and I only expect them to develop faster and faster. The only constant is change. Because I am also a technology fan, the rapid pace of technologies in this market has kept things super interesting.
Why have I stayed a fan? I just think it is an exciting time to be in the telco world, there is something new everyday, and as far as I can see, it is not about to stop, rather it is just starting.
What fascinates you personally about networking possibilities and evolution?
At the moment the range of new technologies available and their development is truly exciting: the decentralization of services to the cloud, software defined networks, and the dramatic increase of technologies that will bring ultra-high speed of connectivity to end users, plus the increasing role of wireless. They will change the way we work, live and enjoy ourselves.
What does it mean for the Sunrise customers? What keeps you occupied at the moment?
At the moment we are in a process of transformation that is critical to keep providing to our customers leading edge technology and best of breed products. We have enlarged our product portfolio with cloud-based services and managed services, which are also integrated, into our processes, and this integration will provide customers with a much faster and much agile way to interact with Sunrise. In addition, SDWAN based services become available as an option to our customers.
We are also leveraging the best mobile network in Switzerland to create new and innovative solutions and creating complementary services for our customers.
What is your vision of the future as far as Connectivity is concerned? Where is it going? What comes after the Cloud?
Cloud based services are already here, and they are here to stay; many more services will migrate to the Cloud. Where do we go from here? Clearly wireless connectivity will become an increasingly important element in the set of options for connectivity. Fiber will continue to be squeezed and more bandwidth will become available to end user. This will enable services like virtual reality, hologram based services, Ultra High definition TV, real time augmented reality, and others still being developed.
But, speed is not all. What will benefit the customers the most in the future will be to have a network that is fully flexible and which automatically adapts to the real time needs of the customers. A network where the customer can decide speed, priorities, and services in real time; and even better, a network that will adapt automatically to customer needs.
