Cerf on managing networks & the need for industry discussion

Google’s Chief Internet Evangelist Vint Cerf, one of the fathers of the Net, has a very thoughtful post up on the Google Public Policy Blog today asking “What’s a Reasonable Approach for Managing Broadband Networks?” He runs through a variety of theoretical approaches to network load management. There’s much there to ponder, but I just wanted to comment briefly on the very last thing he says in the piece:

Over the past few months, I have been talking with engineers at Comcast about some of these network management issues. I’ve been pleased so far with the tone and substance of these conversations, which have helped me to better understand the underlying motivation and rationale for the network management decisions facing Comcast, and the unique characteristics of cable broadband architecture. And as we said a few weeks ago, their commitment to a protocol-agnostic approach to network management is a step in the right direction.

I found this of great interest because for the last few months I have been wondering: (a) why isn’t there more of that sort of inter- and intra-industry dialogue going on, and (b) what could be done to encourage more of it? With the exception of those folks at the extreme fringe of the Net neutrality movement, most rational people involved in this debate accept the fact that there will be legitimate network management issues that industry must deal with from time to time. So, how can we get people in industry — from all quarters of it — to sit down at a negotiating table and hammer things out voluntarily before calling in the regulators to impose ham-handed, inflexible solutions? What we are talking about here is the need for a technical dispute resolution process that doesn’t involve the FCC.

The NY AG’s Anti-Free-Speech Shakedown Racket

Here’s a good article by Declan McCullagh on New York Attorney General Andrew Cuomo’s outrageous vendetta against Usenet. The article is good not only because yours truly is quoted.

I’ve been looking, and haven’t found a single advocate from the left or critic of Comcast’s network management practices that has said a word of support for Comcast on this subject. This is where Internet freedom is really in peril - and nothing?

Tunneling your way around ISP traffic manipulation

Stuck with limited ISP choices, broadband users are increasingly angry with the growing number of providers that poke around in their customers’ traffic. From resetting Bittorrent sessions to sniffing packets for URLs, more and more providers are wielding their power as the “man in the middle” to monitor and manipulate traffic in unpopular and possibly illegal ways. While these practices can be beneficial, tech-savvy consumers are understandably agitated. Congress is now considering legislation that would outlaw these ISP practices.

Instead of urging lawmakers to enact sweeping new laws that would often do more harm than good, broadband users should look to the recent emergence of commercial secure tunneling services. These services remind us that the marketplace is perfectly capable of resolving skirmishes without government getting involved.

Numerous companies have begun to offer encrypted tunnels using Virtual Private Networks (VPNs). These networks have long been used for a variety of reasons, and are popular with network security experts because of how well they protect data from outside snooping. By tunneling traffic through secure links, broadband users can break free from the constraints imposed by ISPs on certain types of traffic. Routing peer to peer applications through these tunnels makes them almost entirely indistinguishable from other types of traffic—even to stateful packet inspection tools like Sandvine that are undeterred by header encryption.

Tunneling traffic via encrypted, remote servers is also one of the toughest targets for ISPs. Many corporate users and university students connect to VPNs for necessary reasons, and there’s no easy way for an ISP to distinguish “legitimate” VPN traffic from the other kind. And with new secure tunneling firms popping up all the time, simply blocking the IP-address ranges of known tunnels is no solution. Absent a VPN Whitelist—highly infeasible given the growing number of VPNs in the wild—ISPs will soon realize that, no matter how much they invest in packet inspection tools like Sandvine and Phorm, informed users will always find a way to stay a step ahead.
