Operation and Optimization Phase
The last phase of the PDIOO life cycle is operation and optimization.As opposed to traditional telephony networks, IPT networks have less need for expensive services and provisioning tools for moves, adds, and changes. Nevertheless, a solid support plan is essential to attain operational excellence for high availability and seamless quality.Operation planning protects the networking investment and provides the operations staff the capability to proactively monitor the network to reduce problems. The following are the important steps that organizations should plan to execute for successful operation of the IPT network:Provide training and hands-on expertise to the support staff on the IPT products operational tools, and network management tools.Involve the key operational staff in the planning and implementation stage of the IPT project.Define escalation procedures and provide resources such as the tools required and product, vendor contacts to troubleshoot user-reported problems and product issues.Define a process to perform the software and hardware upgrades. The process should outline when to perform the software/hardware upgrades, who should be notified when performing the upgrades, etc.Define procedures for managing configuration change requests.Define the backup and restore procedures and backup schedules.Establish a service and support contract with the IPT product vendor.
The optimization phase involves executing steps that help the network to deliver the best possible performance, thus decreasing network issues and reducing revenue losses caused by outages.To optimize the network, the support staff should have a solid understanding of the available operation, monitoring, and optimization tools. Chapter 9 provides detailed information on various tools that are available in Cisco IPT products and optimization techniques.These tools and procedures simplify network expansion, ensure the quality of the network and its applications, focus staffing and training needs, facilitate problem solving, and lower the total cost of ownership.
