Debugging network management scripting applications

A network management scripting application consists of a set of distributed and possibly mobile delegated management scripts, as well as other non-script network management processes, which cooperate with each other to accomplish a given network management task. Such applications require debugging support: firstly, they are distributed applications, and distributed applications are notoriously difficult to debug. More importantly, the network management and the scripting environment exhibit many peculiar characteristics which necessitate special debugging support. The overall issue addressed by this paper is: how can we effectively debug distributed and mobile network management scripting applications? We also present a simple integrated simulation-replay debugger and explain its usage
