Our crawls of the PPLive streaming system yielded client population snapshots and captured the overlay graph among clients. These traces are included below, along with the crawler code.
More details and publications from the project can be found on the PPLive crawler project page.
peerCounter is a system for estimating the online population size of a dynamic p2p system, i.e., number of online hosts. It can be run as a part of any distributed system. The Java implementation of peerCounter, along with an API and an application, are included below.
More details and publications from the project can be found on the peerCounter project page.
DSI is a unified framework of building blocks that are implementations of basic distributed algorithms. It includes implementations of Lamport clocks and distributed mutual exclusion, code for modularly adding distributed algorithms. In the works are blocks for snapshots, termination, and DHTs. The latest version for the DSI code is included below.
Currently, DSI is only deployed in source code form. You may choose to download only the edu.uiuc.dsi.* namespace or download DSI with some examples ready to use and play with right 'out of the box'.
More details about the project can be found on the DSI project page.
MON is an on-demand instantaneous monitoring system intended for wide-area clusters. It is currently deployed on PlanetLab as a service and via a web interface. More details and publications from the project can be found on the MON project page. The source code is available below.
AVMON is a distributed availability-monitoring overlay meant to be robust to selfish and colluding hosts. More details and publications from the project can be found at AVMON's site. The code for AVMON is currently available via http://sf.net/projects/avmon, and it is distributed under the LGPL.
Rappel is p2p delivery vehicle for RSS feeds. The source code is distributed under the BSD-like University of Illinois license.
