Comparison of SECNM's distributed and end-to-end QoS monitoring, regarding a TLS and an unsecured connection

The monitoring structure implemented in this research paper is called SECNM (Single End-Client and Network Monitors). It comprises of a single QoS (Quality of Service) end-client monitor and a QoS network monitor. SECNM's network monitor performs as a QoS distributed monitor, and SECNM's end-client monitor as a QoS end-to-end monitor. SECNM combines these two monitor models. The strength of SECNM is immense when applied to the ensuing scenarios: 1) a plenary QoS end-to-end monitor cannot be applied and 2) a mere network monitor is not adequate. The structure of the SECNM environment was modeled on journals and conference papers regarding QoS monitoring, distributed monitoring, and end-to-end monitoring. A comparison of these theoretical paradigms and SECNM was performed. Test cases were conducted to discriminate the main differences between SECNM's monitor types in the M4MAMI system. The notable discrepancies includes indications of different delays and data quantities, lost data, retransmissions, and initial and final negotiation related to the TLS communication.
