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.
