In this paper, a new approach and solution of the one of the biggest problem on mission critical networks, network and bandwidth optimization will be described. The developed “Network Quality and Resource Manager” ensures the quality of network bandwidth and transfer rate on isolated mission critical networks like high resolution IP based security camera surveillance systems. The “Network Quality and Resource Manager” uses “Quality of Service”, and “Address Resolution Protocol Table” via Simple Network Management Protocol (a.k.a. SNMP) over manage-able at-least 2nd layer network devices. Hence NQRM uses SNMP, it is vendor independent and can work with any network architecture.
