Modern network and applications are significantly different from similar applications developed in the last decade. Authors: Aberman, Noora-Lisa Schiffer, Eva Johnson. If you look at at their technology 15 years ago and today, you will see that nothing changed: just pass me the packet and I will do the rest. In my view (and I think I can also mostly speak for Luigi), we need to go beyond simple packet juggling. In support of the Net-Map method, we also undertook a content analysis of published and. They are not revolutionary in the sense that the idea of memory mapping is out for years, but companies like Endace and Napatech (that used it for so long time) have been unable to use it properly and thus drive innovation anywhere. First of all, both DNA and netmap are not the ultimate goal, but instead some enabling technologies for improving networking on operating systems. So yesterday we’ve not discussed about who’s faster, but we talked about where we wanted to drive our technologies.Īs you can see from the backboard (pictures are courtesy of our common friend Gianmarco), we have some ideas on the next thing to do. And I believe it’s no surprise that the performance of DNA and netmap is basically the same. I decided to go for Linux, he’s a recognized FreeBSD contributor, but our view are not that far.Įven if DNA and netmap have been developed in totally independent ways, they solve the same problem: how to move packets back/forth a network adapter without using too many CPU cycles. I have to admit that if I have started to code in the kernel, it’s also because he has inspired me showing that the kernel was a radical new (for me) way of looking at things. He was telling me about projects he previously did, including a PC-based bridge able to run a few university departments. The first time I saw him (1999 or so) he was hacking a driver for a CD-ROM drive on FreeBSD while speaking with me. I personally know Luigi since almost 15 years as we both live pretty close. Yesterday I had a nice meeting with Luigi Rizzo, the author of netmap. To many people they look like two competing solutions, but in reality they are just two solutions to the same problem. Please do not hesitate to get in contact: jennifer.hauck (at) coknow.In the past months I have received a few emails about how to position DNA with respect to netmap. Of course, the goal of CoKnow is also to develop your capacities to organize inter- and transdisciplinary processes yourself. Your benefits will be an easier and less cost intensive organization of processes, minimizing risks of failure to co-produce relevant knowledge and ensure the co-design of useful solutions for sustainability. I help to explore different worldviews, goals and motivations, integrate different working styles, and planning horizons of all partners involved. More specifically I support you in overcoming barriers of inter- and transdisciplinary cooperation such as language barriers between different scientific disciplines and between science and practice. I support you and your stakeholders to co-produce knowledge and co-design solutions for sustainability! My name is Jennifer Hauck and with CoKnow Consulting I am offering my over 10 years of experience in building capacity for inter- and transdisciplinary processes. Furthermore, you learn some of the most important concepts of social network analysis and we develop your Net-Map pilot study together, including how you enter and analyse quantiative and qualitative network data.Īs a consultancy, CoKnow is offering to conduct complete Net-Map proccesses adapted to your needs. Subsequently, you learn how to use the Net-Map tool, facilitate Net-Map interviews, develop network maps and interpret them.
