Measurement plays an important role in different Peer-to-Peer (P2P)
applications, for the peer selection, data delivery and overlay
construction. Since P2P systems may include hundreds of thousands of
online peers at the same time, it is necessary for the measurements to
be scalable. The P2P system can utilize the measured results to either
improve the system’s performance or ensure the system’s robustness.
For example, Network Coordinate (NC) Systems provide a scalable way
for the measurement and prediction of Internet latencies. And these NC
systems can be used in different P2P applications.

Currently P2P systems are the largest contributor of network traffic on
the Internet. To enhance the data delivery efficiency while reducing the
interdomain traffic, different schemes like P4P or ALTO are proposed. By
utilizing different sources of information, such as routing information from
the ISP or real-time measurement results exchanged among the peers,
traffic optimization can be performed. This can potentially satisfy both
ISP’s operational cost and the users’ experience.
The objective of this special issue is to highlight the recent novel results
that will enhance the measurement-based optimization of P2P
networking and applications. The state-of-the-art research papers will
cover various aspects of scalable measurement and traffic optimization
for P2P systems, including their design, deployment, evaluation, security
issues and applications.

Topics of particular interest include but are not limited to the following:
- Novel scalable measurement architectures
- Network Coordinate (NC) systems
- Deployment of scalable measurement systems
- Security Issues of scalable measurement
- P2P applications based on scalable measurement
- Scalable measurement in mobile P2P
- Congestion control for P2P traffic
- Traffic optimization for P2P
- Traffic localization for P2P
- Proactive network provider participation for P2P
