Broadband traffic management – a thing of the past? #UKNOF28
Broadband traffic management, once an essential tool in an ISPs toolkit is beinsed less and less as the cost of bandwidth decreases.
Broadband traffic management seems to have been ditched some time ago by the big ISPs. I may be behind the times here. Had a conversation with a couple of senior tech guys at major UK ISPs who told me they had dropped traffic management up to two years ago.
Traffic management at an ISP is basically where the network employs Deep Packet Inspection kit to examine the type of traffic. Bandwidth hogging protocols such as P2P would be throttled at peak times. They did this to save on costs and to improve the experience for other users. A peer to peer protocol will use all the available bandwidth on a broadband line. It only takes a few users to clog up the backhaul of an ISP.
When DPI was originally deployed P2P traffic represented up to 65% of network traffic. DPI equipment was expensive, didn’t scale well and at the higher end of ISP size never provided a return on investment.
Now with the DPI kit switched off the “problem” P2P traffic remains at the same level in real terms but now represents only 4% of total traffic, the majority being video services such as Netflix and YouTube (I assume). One ISP told me that when they switched off traffic management they saw a little blip in traffic volume but it was negligible in the great scheme of things.
This is quite interesting when considered in relation to the “piracy” debate. Although copyright infringing downloads may well be at the same level of a few years ago is it valid to say that people are increasingly resorting to the use of legal/paid for services instead? If so it makes the whole Digital Economy Act farce even more farcial.
