IETF 75 Daily Diary – DAY 5, Network Neutrality

I have attended SIDR (secure Inter-domain Routing) and TSV (transport Area WG) today and the details about the presentation and can be found:

For me the main attraction of the day was the Technical Plenary. IRTF and IAB chairs presented their Reports initially and then the stage was set for the debate on Network Neutrality.

Network Neutrality is a broad terminology (in my opinion) however usually it is being discussed in context of the traffic prioritization, blocking and different sort of rate limiting by the operators. So there are two school of thoughts one which supports it by saying that the end user has all the rights to access the content and applications, the other one (usually operators) think otherwise and argue that its really difficult to manage the traffic unless you shape it properly. Also at times different government and bodies (in their own respective economies) block the content.

Like Pakistan, In many parts of Europe the voice over Ip is blocked. This is another major issue due to which this issue was brought in at the IETF forum.

Barbara van Schewick from Stanford law School started the discussion by presenting slides on the subject. From QoS to blocking, from application development to the impact on Entrepreneurs to get funding from VCs – she explained the impact of Network Neutrality at all levels as well as the impact on the future internet development. She concluded by explaining the trade offs as follows

Investment Incentives, Network Innovation, Cost of Regulation
VS
Application Innovation, user control & Internet’s ability to realize its economic, social, Cultural and Political potential

A follow up presentation was made by Mark Handley. In his opening slides he referred to the White paper published with the name of “tussle in cyberspace” which states “different stake holders which are part of the internet milieu have interests that may be adverse to each other and these parties each vie to favor their particular interests. Accommodating this tussle is crucial to the evolution of the network’s technical architecture”

He further explained that this is very much IETF related matter and suggested that the points identified by the operators (against network neutrality) should be handled by focusing on

• Improve TCP’s ability to move traffic away from congested paths
• Multi-server http
• Improve the ability of BiTorrent etc to play nice with low latency applications.
• Encourage “less-than-best-effort” diffserv class
• Work on effecting mechanism to shutdown unwanted traffic

This was very informative presentation I would suggest the readers to go through the full presentation at http://www.ietf.org/proceedings/75/slides/plenaryt-4.pdf
