Modelling dynamics of TCP flows in very large network topologies

Abstract

The article presents an approach to numerical modeling of dynamics of flows in wide area TCP/IP computer networkswith the use of SAPHANAin- memory database. The aim is to explore the possibility of transforming a broadly known modeling method—fluid- flow approximation—into database language, overcoming this way the need to develop dedicated solutions and to transmit the results from the application to the database. We implemented the model logic into SQL procedures and performed mathematical calculations for an exemplary vast topology. The experiments show that the database engine may be used to perform allmodel computations.
