Peer-to-peer (P2P) file sharing has emerged as the dominant usage component of Internet bandwidth. Beginning with the Napster phenomenon of the late 1990s, the popularity of P2P has dramatically increased the volume of data transferred between Internet users. As a result, a rump percentage of the global Internet subscriber base is consuming a disproportionate share of bandwidth – certainly more than the per-user amounts typically provisioned by service providers to ensure a certain level of service and profitability.
Recent studies suggest that file sharing activity accounts for up to 60% of the traffic on any given service provider network. The increase in P2P traffic has dramatically increased network loads and has left service providers scrambling to protect the level of service for their subscribers, particularly for non-P2P users. Moreover, service providers are struggling to avoid, or at least mitigate, the need for unplanned network expenditures. Finally, due to the ad-hoc nature of P2P communication, large amounts of data traffic are indiscriminately pushed onto higher cost network segments (P2P clients don’t care where other P2P clients are located) – driving up network access (NAP) fees.
By increasing the financial pressure on service providers’ already low margins, P2P is quickly undermining the business model for basic Internet access. In the face of deteriorating levels of service, boundless network expenditures, and surging monthly bandwidth fees, the traditional provider approach – managing network costs through over-subscription – is no longer sufficient.
Yet the enormous popularity of file sharing and the breadth of competing protocols makes blocking P2P traffic a practical impossibility. Service providers have begun to experiment with tiered pricing based on monthly bandwidth consumption, or capping the amount of bandwidth available to P2P applications, but these approaches can easily be positioned as punitive by Internet lobby groups and competitors, generating dissatisfaction amongst subscribers and potentially aggravating customer churn.
This document explores the technology and infrastructure behind peer-to-peer file sharing, and its implications for long-term service provider profitability.
