Conclusions
• > 90 % peer-to-peer, dominating the traffic pattern
• High penetration of peer-to-peer (>80%), A/V streaming (>95%), VoIP (60%), http (100%)
• Asymmetric traffic (Outbound dominating, coming from peer-to-peer applications)
• 10 % of the households use 67 % of the traffic
• No big difference between peak hour and overall traffic mix
• < 3 % unknown
