3 Law of Telecom Complexity Telecom complexity, C, is calculated roughly as: C (Number of protocol domains) X (Number of networks per domain) X (Average number of inter-network interfaces per network) Over time, T, the number of protocol domains increases proportional to T The number of networks per domain increases proportional to T The number of inter-network interfaces per network is proportional to the number of networks per domain Hence, C T Venture Partners All Rights Reserved

14 Transaction-based DPM Methodology Understand how the services are provided via their transactions Define how transactions are defective for the services provided Failures in Accessibility, Continuity & Fulfillment under service s Operational Profile Failure Modes and Effects Analysis (FMEA) Measure the services provided for defects on IP Edge Router Analyze what happens to the defined transactions (opportunities) Control service to maintain a high level of quality 14

15 IP DPM Measurements View Services as a collection of transactions that are invoked under a specified Operational Profile with a Focus on Probability(Successful Transaction) Port Accessibility - probability of successfully initiating a transaction. This is the availability of any communication path into the service. Continuity - probability of successfully completing an initiated transaction. Fulfillment - probability of completing transactions within acceptable performance/service bounds. Flow-Through: probability of automatically flowing through the factory defects Proposal: Develop a mathematical methodology to track and link IP Edge Network defect metrics to the system and process metrics (including availability and latency) within Management Control Plane. 15
