What will you be doing?

The increasing popularity of Internet-Protocol (IP) based services has accelerated the evolution of consumer’s home networks. This led to growing number of devices for use in a home, and as the result, a home network became a complex environment providing connectivity to number of  devices with different capabilities and with different communication interfaces.
Any given home may now have one or more PCs, laptops, smartphones, tablets, Internet radio devices, set-top-boxes, network-attached storage devices, digital photo frames, game consoles, Internet phones, and printer servers, all interconnected via a combination of Ethernet switches, WiFi access points, power line bridges, and cordless telephony base stations. These devices are often networked with each other in various ways, and connected to the managed operator network and the Internet via one or more Home Gateways (HGs)..Our scope is network topology discovery at home, thus limiting types of devices that can be found here. Examples include Residential Gateway (RG), Set-top Box (STB), Network Access Storage (NAS), …
Topology is  defined as a list of active devices and their capabilities, a list of connections between devices, and on a per-connection base the link technology that is used. Note that for describing a network, we can use single topology which unifies all available communication interfaces, so focus on connectivity and not on technology.
Alternatively, we can use communication technology view on network topology – having one network topology description for each given communication interface. In this model, devices with multiple interfaces are participating in different networks. Devices with multiple interfaces can (but do not have to) act as gateways between two networks. Also, we can have  multi-homed devices, which have multiple communication interfaces active at the same time.
We now aim at deepening our understanding of home network topology discovery mechanisms, and have to tackle the following challenges:
  • Analysis of existing topology discovery mechanisms, including their limitations
  • Creation of methods to provide accurate and timely network topology, while keeping overhead signaling low
  • Implementing and proving that chosen method can provide complete network topology.
Within this context, we are looking for candidates to graduate with us. Currently we have space for one final-year master student to work on the home network topology and discovery.

What do we require of you?

Top students are invited to apply. You need to have a good knowledge of Computer Networking, topology discovery protocol, and data analysis. Your practical and communication skills will be greatly involved in case we decide to extend our measurement campaign taking place at people’s homes.

What can you expect of your work situation?

TNO is an independent research organisation whose expertise and research make an important contribution to the competitiveness of companies and organisations, to the economy and to the quality of society as a whole. Innovation with purpose is what TNO stands for. With 3000 people we develop knowledge not for its own sake but for practical application. To create new products that make life more pleasant and valuable and help companies innovate. To find creative answers to the questions posed by society. We work for a variety of customers: governments, the SME sector, large companies, service providers and non-governmental organisations. Working together on new knowledge, better products and clear recommendations for policy and processes. In everything we do, impact is the key. Our product and process innovations and recommendations are only worth something if our customers can use them to boost their competitiveness.

What can TNO offer you?

You want to work on the precursor of your career; a work placement gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development. You will, of course, be properly supervised during your work placement and be given the scope for you to get the best out of yourself. Naturally, we provide suitable work placement compensation.
