1. P2P 2.0 and it’s impact on the Internet 1

2. The Outstanding Success of P2P 1.0
44% of all Global Internet traffic – in some countries up to 80%
Used for file sharing (Bittorrent), VoIP (Skype) and lookup services
Mostly focused on the need of the end users

3. The Problems of P2P 1.0
Random or unstructured traffic patterns – plaguing ISPs and lowering overall performance
Low or no QoS
Poor peer resource efficiency

4. Guiding P2P 2.0 Design Principles
How can we address these issues with P2P 2.0?
Care about the whole business ecosystem: distributer/sharers, ISPs and end users
Network Topology Aware – keep traffic local!
Efficient Peer Resource Management – semi global or global optimizations vs old heuristic rules
Predictable QoS
P2P 2.0 enables efficient high bandwidth services such as Video Streaming, Storage/backup and Cloud like services

5. P2P 2.0 example 1:
Video Streaming 5

6. P2P Live Video Streaming
Video Source
P2P Source
P2P Optimizer
P2P Tracker
NAT helper
Characteristics:
Consumes very little bandwidth (80-98% less)
Network Topology Aware
Scales almost infinitely

7. P2P 2.0 example 2:
The New Pirate Bay 7

8. Pirate Bay’s Tracker Today
TPB’s Open Tracker v1.0 manages ~15% of global Internet traffic
Is written by Dirk Engling and uses Bram Cohen’s vanilla Bittorrent protocol
Tracks around 2 million torrents and 25 millions users at any given time
Creates huge amounts of redundant traffic due to random peer pairing
Throughout history mankind has made huge efforts to organize people and the flow of information
Some have proven less successful, e.g. communism, while others, though not flawless, show more promise, e.g. capitalism
The hunt for the perfect system has forever haunted thinkers
This is about to change …

9. Open Tracker 2.0 We improve Open Tracker by adding network awareness
We use a global network map to keep traffic local
We allow ISPs to put costs on each link and we optimize accordingly
We see 20-50% less traffic loads and % higher download speeds
Requires no Bittorrent client changes
Will be launched as free open source in September

14. Conclusions
P2P has matured into 2.0 and is ready to delivery efficient services with QoS guarantees
P2P 2.0 cares about the whole business ecosystem
Huge traffic and performance improvements can be achieved compared to P2P 1.0
