If you are an ISP, or your clients are ISP’s then you might need to know what is keeping them up at night. Here is an interesting analysis of what uses up an ISP’s bandwidth, produced by CacheLogic. It appears that most bandwidth is used by peer-to-peer (P2P) services – remember Napster? The rest of the web’s traffic is negligible compared to P2P file-sharing, much of which is legal, so it’s not just music and videos. The following myths are debunked in CacheLogic’s analysis:
- P2P is in decline
- P2P is all about MP3’s
- The P2P problem is caused by a few heavy users
The authors believe that P2P has provided the blueprint for the next generation of web applications, so if you’re in this business, you’d better understand what is important to your customers and how you can help them. For the rest of us, P2P may wind up costing us more as it keeps chewing up available bandwidth, or it might squeeze out more traditional traffic. Some of this is beyond me, but it seems to be a significant phenomenon.
