There are some papers written on this subject --- most notably [1] and [2] --- but [1] is fairly dated and [2] scratches the surface. Hardware (multicore machines) and software (parallel programming frameworks) advances have allowed greater flexibility in simulating large-scale systems today. I think that having p2prg look deeper into a survey of p2p simulators may be of interest to both academics as well as practitioners. I have started the ball rolling by submitting a document [3] that gathers some of my thoughts on how to proceed. The document is not complete, nor do I claim that it is comprehensive. To impart these properties, I would need help from the p2prg community, especially those of you who are currently working with simulation frameworks. Can you please read [3] --- it is a short draft --- and see if this is of interest to you? I have requested an agenda slot in Prague, but it'll be great if we could have a larger discussion on this (not to mention some volunteer editors) before the Prague meeting.

It would probably be helpful to add a section (e.g., before Section 3) that discusses the problem space: What are important requirements for P2P simulators? Some minor comments: *Introduction*: The draft may also be a guidance for people, who want to develop their own P2P simulators. *Criteria for evaluating simulation frameworks* Support for other models (Churn, ALTO, etc.) *List of simulation frameworks* There is also PeerfactSim (http://peerfact.kom.e-technik.tu-darmstadt.de/), which provides a good model for the Internet delay space. This is important for proximity-based peer selection. Cheers matthias -- Matthias Waehlisch . Freie Universitaet Berlin, Inst. fuer Informatik, AG CST .

To which extent are properties like churn a function of the model itself versus an intrinsic service that the simulator framework should provide? In other words, if I look at ns-3, I can develop a Chord application model and imbue it with a churn rate of my choosing. NS-3 does not have to do anything special. Thoughts? > *List of simulation frameworks* > > There is also PeerfactSim > (http://peerfact.kom.e-technik.tu-darmstadt.de/), which provides a good > model for the Internet delay space. This is important for > proximity-based peer selection. Cool; added in my working copy.

I am currently involved in a national project about P2P streaming. In =20 the last meeting we agreed that a problem in this field is that there =20 is no "standard" (in a weak sense) methodology to compare performances =20 of P2P systems and this makes it difficult to compare different =20 solutions. Therefore, we are trying to find one or more standard "use =20 cases" to be used to compare different P2P systems. The problem is quite complex, both because of the complexity of the =20 "boundary conditions" of your system (e.g., number of nodes, churn =20 level, network congestion status, ...) and the "performance value" you =20 want to measure: what do you measure? Overall SNR at the receiver? =20 Probability of "video freezing"? Variance of SNR? Start-up times? =20 Delay from source to receiver? (clearly those measures are related =20 with streaming applications, other applications could use different =20 quality figures) . Moreover, there are some "parameters" that could =20 be considered as part of the "boundary conditions" or as part of the =20 system to be measured (e.g., network topology). I am _not_ saying that this type of consideration should be included =20 in the draft (they could be included, they could be part of a =20 different draft or they could be discarded right away), but maybe the =20 two aspects (what p2p simulation systems are available and how they =20 should be used) are related. Just my 0.02 thrown in the discussion. Greetings, Riccardo Quoting "Vijay K. Gurbani" : > Folks: To the best of my knowledge, there isn't a large-scale > survey of p2p simulators today.

To a certain extent, p2p file-sharing systems are well understood since the academic community has looked at them for a good while now. So, it is easier to extrapolate the requirements of a simulator for a p2p file- sharing type of application. P2P streaming applications, obviously, have different demands than do static file-sharing ones. I would love to include some considerations for a simulator framework to support p2p streaming-type of applications. However, as usual it will boil down to interest (*many* people have lots of this) versus time (*all* people have much less of this) and expertise (*some* people have lots of this). If your interest is high, and you have the time and expertise to contribute insights on what p2p streaming applications would require of a simulator framework, I would much appreciate working with you to get some text into the draft (and again, I am not saying we need to do this before Prague, but by the time the p2prg meets next, we should take a reasonable stab at this).

Thoughts? > I don't know if I understand it correctly. NS-3 is a discrete event simulator, which provides a basic set of functions (mainly handling events etc.) to implement different models. To implement churn, NS-3 does not have to do anything special. There are properties that require their own model and that makes only sense in a narrowed scenario. For example, in a dedicated P2P simualtor we would not expect an extensive layer 2 model, but may expect a detailed underlay topology support. Btw: Churn is good example that properties may be intricate. Churn may result from application/user behaviour or node behaviour (e.g., due to node movement and lossy WLAN). This results more or less in the question of abstraction: Is it necessary to account for the latter in P2P? > Before Prague, I will make my working copy available at a public site > if the comments pore in (which I hope they do).

And it even gets more complicated if you want to establish it as reference model ... Analyzing the general "boundary conditions" and "performance measures" for P2P systems could be part of a problem statement as it is necessary to evaluate the simulators. General side remark: A "standard methodology" to compare different solutions is not only missing in the context of P2P, but also in the broader network community. In contrast to the video coding people, for example, we have no real reference models/scenarios. This problem is mainly related to researchers, but it could be an interesting symbiosis of IETF and IRTF to develop such reference models. Best regards matthias -- Matthias Waehlisch .

I was merely trying to point out that as we look at the simulation frameworks, one way to characterize them could be what sort of p2p-like services they provide intrinsically (i.e., the user does not have to add the behaviour to the simulator explicitly). Churn is one such service. NS-3 will not provide it natively, but other simulators may (does anyone know if dedicated p2p simulators provide knobs to control the churn rate?) Replication is another service that may be provided by a dedicated p2p simulator but would need to be explicitly put into a model running over ns-3. Thanks, - vijay -- Vijay K.

It supports NoChurn (after all the nodes have been added to the network, no nodes leave), LifetimeChurn (a node's lifetime is selected randomly based on a given probability), ParetoChurn (using heavily tailed Pareto distribution of node lifetimes), RandomChurn (selecting a node at random after a fixed interval).

Is there any remedy for this in the research field? Flow level or message level simulators may be more scalable in the sense that they generate less number of events. Distributed simulation is another way to scale. One of the outputs of the work under consideration will be to look at the scalability aspects of the most commonly used simulators.

That is one way to look at it --- while ns-3 does not provide the notion of "churn" itself, it does provide the ability to bring hosts up and down thereby *causing* churn at the DHT layer. The DHT application model itself can schedule events to bring a host up or down, thereby inducing churn into the system. >> but other simulators may (does anyone know if dedicated p2p simulators >> provide knobs to control the churn rate?) >> > OverSim, which is P2P framework for OMNeT++, provides several churn > models.

The same can be approximated in ns-3 if we had a Chord model in ns-3 and the model had a "churn" attribute. BTW, we have publicly released a CAN DHT model in ns-3 [1], in case anyone is interested. We are working to make it scale to 1 million nodes. We have not introduced churn into our CAN DHT model yet.

It obviously depends on the complexity of the overall model in use (which type of underlying topology, etc.). Cheers matthias -- Matthias Waehlisch .

We have got to 2^14 nodes and have stretched it a bit beyond that. However, the time it takes to create the DHT topology increases non-linearly beyond a certain point. We are looking into why this is the case. Thanks, - vijay -- Vijay K.

Please help us by taking a 7-question, 5-min anonymous survey: http://www.surveymonkey.com/s/B6PCRXY We're interested in your input even if you have not used testbeds (or heard about them). This is an NSF-funded study with a potential to influence how testbeds are funded and managed so your input may have real impact on network research. Results of the study will be released publicly at http://www.isi.edu/~mirkovic/Testbeds Thank you ------------------------------------- Jelena Mirkovic Alefiya Hussain USC Information Sciences Institute
