p2psim: accordion faqWhat is Accordion?
The Accordion protocol is described in a NSDI'05 paper.
How do I run Accordion?
You can run it like any other protocol, but you can also use our
scripts/run-simulations.pl --protocol Accordion \ --topology your_favorate_topology_file \ --logdir . --args examples/accordion_args
What do Accordion protocol parameters mean?
A typical Accordion protocol file looks like this:
Accordion successors=16 basictimer=144000 burst=100 initstate=1 overhead_rate=8
Accordion uses the same sucessor stabilization method as Chord. successors=8 specifies the number of successors and basictimer=144000 specifies how often (144 sec) an Accordion node should contact its successor to check its liveness.
Accordion bounds the overhead traffic to be 8 bytes/second with a burst size of 8*100 bytes. The overhead traffic consists of successor stabilization messages, active exploration messages to acquire more state, parallel (or non-parallel) lookup messages including both originated and forwarded lookup traffic.
