Conclusions and future work
A Process for remotely accessing MMC is developed Training tools for customers (AIMS, Java Test Tool,
Tactel, etc.) AIMS is fixed for MMS usage. Java Traffic Tool is developed
Interference Shielding of AIMS Load Testing Tools should be used Deeper understanding of tools usage Additional tools for service Portfolio of MMS
