Traffic Measurement and Data Analysis
It is essential for IIJ to understand recent trends in customer traffic.
We will provide an internship student an opportunity to work on a small measurement project, possibly using real-world datasets from IIJ's services, in order to provide practical feedback to IIJ's services.
Possible topics are:
- development of traffic visualization tools (e.g., for multi-dimensional traffic time-series or for video streaming quality)
- development of algorithms to provide compact summary information of large-scale traffic data
- analysis of video streaming traffic behaviors (e.g., differences in video segment fetching strategies)
- modeling and simulation of network traffic
- development of monitoring tools for large-scale measurement platforms (e.g. detect outages or identify physical topology from traceroute datasets)
- the mining of big data, such as the detection and correlation of control and data plane events
We are looking for a graduate student for a two-month-long full-time internship. Candidates should have good skills in computer networking, UNIX systems, and programming as well as oral and written communication skills in English.
For data analysis, skills in machine learning techniques and knowledge of statistics are also required.
To complete a project in two months, a candidate should have substantial experiences in the selected research topic.
Library Operating System
With the name of specialization, various academic and open source projects invented different shape of network stacks and operating systems. While the specializations avoiding generalization tax solve specific problems of network stack, those are often coupled with the downgraded features due to the specializations, which are hard to recover because the feature richness usually comes with the incremental growth of operating systems.
As a result, there are still serious problems of conventional network stack and library operating systems (or userspace network stacks):
- network stack ossification (hard to introduce new features), lack of personality
- lack of generality, resulting no legacy application support
- simply waste of time (if it is implemented from scratch)
The primary goal of this project is 1) to alleviate the current issue of network stacks, and 2) to retain the feature-richness of the current operating systems by morphing a monolithic kernel into an anykernel implementation (a.k.a. library operating system). The concept of library operating system is not new but it is emerging to address current issues on operating system and network stack.
The objective of this project is to design and develop an implementation of library operating system, Linux Kernel Library (or LKL), to solve aforementioned issues of current operating system.
Possible topics (but not limited to) are:
- supporting general applications with feature-rich network stack
- benchmark studies with the implemented software to understand the bottlenecks (incl. comparison with alternatives)
- container runtime integration
- fast data plane for virtual network functions with LKL
We are looking for graduate students who have the following knowledge and skills.
- Knowledge of computer science and networking technology (or equivalent)
- Skills of system programmings in C
- Knowledge and/or experience of Linux kernel development
- Knowledge and/or experience of network performance benchmarks
SDN IXP Switching Fabric
The objective of the internship is to provide interns with opportunities to develop, and enhance Internet eXchange switching Fabric with SDN OpenFlow.
Among the possible topics are
- Developing management tools for SDN Internet eXchange
- SDN Internet eXchange scalability measurement and development
- OpenFlow hardware evaluations
- Study SDN solution for ensuring IXPs operation
The intern will receive support and feedback from IIJ Research Laboratory and a range of external research collaborators along the way.
We are looking for a graduate student in Computer Science or Electrical Engineering to complete a two month full-time internship. Candidates should be competent in computer networking, UNIX systems, Python programming and Software Defined Networking concept. Knowledge of OpenFlow, FAUCET controller and IP routing protocols BGP would be a plus. In addition to the above, candidates should have strong practical and problem-solving skills, the ability to independently produce high quality work, and good English oral and written communication skills.
Internet Health Report
The Internet Health Report (IHR) leverages data collected by large measurement platforms (e.g. RIPE Atlas, RIS, and RouteViews) to automatically pinpoint connectivity issues in remote networks (https://ihr.iijlab.net/). IHR is looking for talented students and skilled programmers to develop new analysis tools and improve the usability of existing tools. This is a great opportunity for students to work with our large datasets and develop practical and open source tools for network operators, researchers, and Internet users.
Internships for the Internet Health Report are supported by the RIPE NCC Community Projects Fund.
Possible topics include:
- Back-end development: Near-real time data analysis (experience in python required)
- Development of monitoring tools for large-scale measurement platforms (e.g. monitoring latencies or identify physical topology from traceroutes)
- Analysis or applications of IHR results
Messages from Alumni
Arun Dunna (Year 2019)
I thoroughly enjoyed my time at IIJII, and the process was enjoyable from the initial application through the end of the internship. After I applied, I had an engaging video interview with some team members, and we discussed my prior work and potential projects at IIJII. Throughout the whole process, IIJII made it a point to ensure that I would be working on a project that I took interest in, which could be changed even upon arrival. Kitamura-san made the typical nightmare of logistics a breeze, and promptly answered any questions I had not just about the internship, but about life in Tokyo.
Upon arrival in Tokyo, I was greeted by the lab and given time to get acclimated to Japan. The lab's atmosphere was both welcoming and engaging, and everyone in the lab made regular efforts to discuss my project and provide input/guidance if needed. The locations of the office and provided housing were phenomenal, and Kitamura-san explained how to use the public transport to get around the city.
Daily life in Japan itself was great, and I highly recommend it to expand world viewpoints, which is another benefit to the internship. As an intern, I was required to be in the lab for a set time range each day, but a generous lunch slot was included and the lab provided a quiet yet collaborative space to work. My advisors (Romain and Zach) were at the lab nearly every moment that I was, and were hands-on throughout the whole internship, including regular meetings, online and in-person discussions, and collaborative brainstorming. All lab members were incredibly knowledgeable and were happy to answer any questions that I had, or to provide input when requested.
Overall, IIJII made a daunting internship in a foreign culture an enjoyable breeze. I made sustainable professional connections and produced quality research work as a part of their team. I highly recommend applying to the internship - it has been one of the best decisions of my academic career. I still continue to collaborate with the IIJII group even months after the internship on a number of projects.

When can I get the details of my flight?
IIJ will arrange the flight ticket after the certificate of eligibility is issued.
I would like to fly from France and fly back to US. Could IIJ provide the whole flight tickets?
No, we will provide a round trip ticket only.
Other information staying in Japan
Will travel insurance be provided by IIJ?
No, IIJ will not provide the insurance. You must make your own arrangements to join a travel insurance plan before you leave for Japan. We recommend that you have travel insurance which also covers flight delays, lost baggage etc.
How can I receive my salary? Do you transfer to my overseas account?
