Abstract

The use of the internet network since the covid-19 pandemic is increasingly needed as the backbone of the implementation of mobile technology, websites, and desktops where all of them utilize network infrastructure and servers. The use of the right enterprise network combined with adequate server management results in optimal access and stable network conditions. The more complex the network that is built, the more server needs are needed and the more complicated the queuing algorithm that is built to produce the appropriate access speed and optimal storage. Behind these needs, there are several algorithms that can be implemented to optimize the application of enterprise networks.In this study, the implementation of a comparison between the RED, SFQ, and AQM algorithms on RouterOS and VMware ESXi in an enterprise network, in this case a university-scale internet network, is carried out. RouterOS was chosen because most of the networks in the agency, especially using Mikrotik RouterOS for network management and monitoring, while VMware ESXi is used as a virtualization server that can replace many physical servers into one server by implementing virtualization in it to be more practical and efficient. The implementation of the RED, SFQ, and AQM algorithms was tested during March to July and the results showed that the AQM throughput test value was greater than RED and SFQ by 91.4%, the delay and packet loss test values of AQM were better than RED and SFQ by 7% and 8856 ms.Keywords: VMware ESXi, RED, SFQ, AQM,, routerOS.

Abstract

University requires the integration of data from one system with other systems as needed. This is because there are still many processes to input the same data but with different information systems. The application of data integration generally has several obstacles, one of which is due to the diversity of databases used by each information system. Schema matching is one method that can be used to overcome data integration problems caused by database diversity. The schema matching method used in this research is linguistic and constraint. The results of the matching scheme are used as material for optimizing data integration at the database level. The optimization process shows a change in the number of tables and attributes in the database that is a decrease in the number of tables by 13 tables and 492 attributes. The changes were caused by some tables and attributes were omitted and normalized. This research shows that after optimization, data integration becomes better because the data was connected and used by other systems has increased by 46.67% from the previous amount. This causes the same data entry on different systems can be reduced and also data inconsistencies caused by duplication of data on different systems can be minimized.
