Controlling of Quality of Service in Campus Area Network Using OpenDaylight with Hierarchical Token Bucket Method

Quality of Service on TCP / IP networks is focused on allocating bandwidth that flows in accordance with service requirements on the network. It aims to allocate guaranteed bandwidth for each service used. The increasing number of Internet users on campus networks will automatically affect the quality of services on the network. Therefore, we need a system that can improve the quality of network services by limiting the bandwidth for each service that runs. Hierarchical Token Bucket (HTB) is one method of bandwidth allocation. HTB has the task of limiting bandwidth and arranging packet queues based on priority. HTB method application is done using Software-Defined Networking (SDN) technology. SDN is a network technology that uses OpenFlow as the protocol. While OpenDaylight is one of the SDN-based controllers that supports the OpenFlow protocol. The HTB method is connected to the OpenDaylight controller via the REST API. The results obtained from four types of scenarios performed, resulting in a throughput of 10.15 Mbps, 7.08 Mbps, 3.08 Mbps for HTTP, FTP, and SMTP services respectively.
