Peer To Peer Networking Course at TUT

Once again from Professor Harju's email announcement: TLT-2486 ADVANCED COURSE IN BROADBAND NETWORKS, 3 cr The topic of this seminar course in Spring 2007 is *Peer-to-Peer Networking*. The course is suitable for postgraduate studies. The course starts on Friday, February 6, 2007 at 12.15 in TB111. For more information, see http://www.cs.tut.fi/kurssit/TLT-2486/ P2P systems are dynamic networks of peers that create an overlay network on top of the Internet Protocol (IP) network. P2P networks can aggregate enormous storage and processing resources while minimising entry and scaling costs. There are a lot of ways how these overlay networks can be formed and managed, and how content is stored into and searched from these networks. The aim of the course is to give a comprehensive and up-to-date view of the different mechanisms and aspects involved.

Networking presentation at TUT

Once in a while there are presentations at Tampere University of Technology from visiting researchers, which might interest also Modeemi's network-oriented members. Noticed this this morning so please excuse me for late announcement. Shamelessly ripping off Professor Harju's mail: Dr. Tuomas Aura Microsoft Research, Cambridge, UK will give a presentation on "Pitfalls in Internet mobility and multihoming" on Monday, January 29, 2007 at 13.15 - 14.00 in TB224, Tietotalo, TUT. Abstract: Mobility, dynamic addressing, and multihoming features are being added to network protocols at all layers of the protocol stack to enable movement and to increase reliability. By misusing such features, an attacker may be able to hijack data and connections, prevent legitimate communication, and cause a packet flood. In this talk, I will show examples of what has gone wrong in standard protocols such as Mobile IPv6, SCTP and SIP. Fortunately, simple, inexpensive design principles have enabled us to prevent such attacks.
