Future InterNet Design

I attened one workshop at Forum ATENA in which Vincet Cerf and Bob Khan presented their view on the future of the Internet (cloud Computing), and openness in the Internet architecture.


Last Monday, 28-06-2010 I attended another workshop in which John Day , professor of the Univerisity of Boston, spoke on "Future InterNet Design". There are other three speakers: Guy Pujolle, Kave Salamatian and Michel Riguidel. Since their presentation are in French, I dont have enough capability to understand completely. All the slides can be found in here.


John Day recalled the OSI model that has seven unanswered questions, myths and reality. Returning to the fundamentals is a key important for designing the network architecture.




Many of his efforts (RINA - Recursive Internet Architecture) can be found in here. Besides, there is an initiative to design a new network architecture, called the Pouzin Society. There are plenty of documents which can help to understand the network architecutre and key points for new design. To get more, visit here.

Unconventional Network or Challenged Network

Today, I attended the talk delivered by Dr Roch Glitho at Telecom SudParis. His talk was mainly about the unconventional network (Solar network, wireless sensor network and MANET) that forced to shrink the five layers TCP/IP stack into three layers such as Application, Middleware (Routing and transport) and telecommunication layer (MAC and phy).

He presented two middlewares such as IETF delay/disruption tolerant network (DTN) bundle overlay and the EU 6FP ambient control space (ACS) overlay. Application developer should know about these overlays for developing the services in addition to the business logic. Moreover, interconnections of different overlays will pose big hurdle for user experience.

Kiitos (Thanks in Finnish) to the UBI Summer School Program and UBI Challenge

After a lot of fun and series of group work, we concluded successfully the Summer school on 04-06-2010. Many ideas based on the concept of UBI Display/UBI Hotspot are presented for the evaluation. One clear observation is that each presentation has at least one slide that has Google map of Oulu.

UBI Display is a kind of computer sharing by many people in the city. In this case, users are getting a private space for performing their task (Ex using Web Browser).

UBI Hotspot is a kind of access point (Ex. WiFi Access point), terminology coming from Networking people, for providing the network access to personal devices of the users Ex. Blue Tooth/Wireless Sensor Network).


UBI Challenge
The information about the UBI Challenge contest is my main take away. As a researcher, I feel that R&D assets from the UBI program is huge and can be used to experiment new technological solutions.

One idea would be to propose UBI store where users can create and share new applications and media with others for business benefits.This idea is based on the current trend from the servoce providers and a CELTRIC project called SERVERY.

I would like to particpate this contest. Please feel free to invite me if you have any new ideas to discuss.

All the photos of the UBI summer school program taken by my camera are uploaded into Picasa.

After Sauna and Jacuzzi, 6LoWPAN

We all went to the get-together party evening. It was so excitement when I got first experience of Sauna and Jacuzzi. After the many Finnish beers, I was completely down.

I attened IP based wireless sensor network (WSN) workshop. Tutor is an author of 6LoWPAN book. Zach views the WSN from the networking point of view - connecting the WSN with Internet or fitting into the TCP/IP stack. 6LowPAN reduces IPv6 header from 48 bytes to 2 bytes.

More interesting point for me is that there is a need to go for the new apppliction protocol for the WSN. This new protocol is a kind of optimization of HTTP (reduce overhead) and has new features such as eventing/push support natively. Zach et al propose a new protocol called Constrained Application Protocol - CoAP.

It is in the line of changing the user model of the web that consits of HTTP, URI and HTML. This concept is written in the paper "The smart internet: transforming the web for the user".
