Abstract

The article presents an approach to numerical modeling of dynamics of flows in wide area TCP/IP computer networks with the use of SAP HANA in-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 all model computations.
