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
