In Europe, a large fraction of the Internet traffic is exchanged at interconnection points such as LINX in London, BNIX in Belgium, SFINX, in Paris. AMS-IX, based in Amsterdam is one of the oldest and the largest interconnection points in Europe.

Researchers who are working on improving BGP are familar with popular sources of BGP updates and tables including :

In order to add new EAP methods to the linux implementation of IEEE802.1X, I had to make the protocol work on a wire. Since I had some difficulties to succeed and to find sample examples for wired connection, I publish these sample configuration here. I hope it will help.

It is based on hostapd and wpa_supplicant 0.6.4. To compile them, go in the hostapd/wpa_supplicant directory, copy "defconfig" to ".config", for hostapd uncomment the line "CONFIG_DRIVER_WIRED=y" and "make".

Hostapd (the authenticator)

During the Defcon conference, two security researchers have shown by a live exploit that interdomain routing with today's BGP is not secure. Additional details about the exploit may be found in :

The IETF is becoming more and more concerned about the need to migrate to IPv6 and the difficulty of migrating the Internet to something else than the current IPv4. During the Dublin meeting, there were several interesting presentations about IPv6 :

• Google's IPv6 deployment started as a 20% project like gmail, but it is progressing quickly and we can expect more and more IPv6 content from google : http://www3.ietf.org/proceedings/08jul/slides/plenaryw-4.pdf
  

This book written by Robin Sharp and published by Springer Verlag takes an unusual path to describe computer network protocols. While most standard networking texts mainly focus on a textual description of the different protocols and mechanisms, Robin Sharp starts from formal description techniques. More precisely, he chooses the Communicating Sequential Processes (CSP) notation proposed by Hoare. CSP is a process algebra that allows to model the interactions among communicating processes.

This paper introduce a "new" allocation scheme for address block that is growth-based. It uses growth rate information of customers for optimizing the allocation. An evaluation is made on historical date from APNIC and China.
