I implemented multiple simulation environments for different network protocol then SimPy have a lot of pre implemented API that helps to have clean code based and optimized outputs. Review collected by and hosted on G2.com. What do you dislike about SimPy? While I think SimPy has the most API necessary for the different simulation applications, the main downside is lack of good documentations. I needed to spend a lot of time to read the code my self to learn how to exactly use different APIs. I suggest to have multiple advance examples with a detailed descriptions. Review collected by and hosted on G2.com. What problems is SimPy solving and how is that benefiting you? I am in charge of designing communication protocols for different gaming or networking applications. We use several custom network protocols, one of the downsides of using custom protocols is that we need to tune several parameters to reach the best performance, I use SimPy to implement the such network protocol in a simulated environment so I can test several parameters to find the best one. SimPy have a pretty good API to support such simulations and also it makes the whole simulation process much easier Review collected by and hosted on G2.com.

As it is python based, the main pro is easy to use and further, It provides diverse resources to model congestion points like tunnels and servers. also it usage simple components. Review collected by and hosted on G2.com. What do you dislike about SimPy? Need improvement in the library and practically no help in continuous simulation. Review collected by and hosted on G2.com. What problems is SimPy solving and how is that benefiting you? I use SimPy for simple simulation projects where there is a bank and number of tellers. Review collected by and hosted on G2.com.
