Do you refer to the Scripting Service example application of RSPLIB, which is
used e.g. for SimProcTC (see
http://www.exp-math.uni-essen.de/~dreibh/omnetpp/
) or computation workload distribution (see http://tdrwww.exp-math.uni-
essen.de/dreibholz/rserpool/rserpool-publications/NGComNet2009-SCTP-and-
RSerPool-Student.pdf )? The Scripting Service is just one of many
applications
which can use RSerPool.

RSerPool/RSPLIB only provides the foundation for reliable and redundant
services, i.e. it manages server pools and handles sessions with these pools.
For a detailed introduction, see http://duepublico.uni-duisburg-
essen.de/servlets/DerivateServlet/Derivate-16326/Dre2006-final.pdf . The
behaviour of the application is in the responsibility of the application
itself, i.e. the application may implement arbitrary mechanisms to handle
workload over the RSerPool sessions. For example, the Scripting Service
distributes complete applications while the Fractal Generator Service (also
included as example in the RSPLIB package) provides its own protocol for
requesting graphics computations.

For more specific descriptions, I need some more information about your
application and its communication patterns.


Best regards
