  9. C2 - Eingeschränkte Verwendung INA INA‘s FEATURES
  10. C2 - Eingeschränkte Verwendung INA • INA uses near real-time data that includes real network statistics, up-to-date topology and routing information across all network layers. • INA simulates topology changes and their impact on data traffic and latency. • Complex root-cause and impact analyses can be applied at any granularity, including subnetwork, site and individual devices down to a single port. SIMULATION BASED PLANNING INA as digital twin represents the as is E2E network and simulates planned network changes.
  11. C2 - Eingeschränkte Verwendung INA A new link should be added in order to decrease the utilization on the overloaded red link If the link is inserted at this point, an overload will occur at a new point. SIMULATION BASED PLANNING This location for the new link is suitable as the traffic now runs via different routes and thus no longer causes congestion
  12. C2 - Eingeschränkte Verwendung INA TROUBLESHOOTING INA: In case of an outage, not only directly connected antennas can be identified, but also wider effects on the network are easy to discover • Impact Analysis is easily possible to conduct - Identification of impacted sites - Consideration of all routed traffic - identification of all dependent antennas • Use cases: Power outages, malfunctioning network elements, environmental influences, sabotage • INA interfaces with ticketing systems and can correlate to actual incidents or changes in near real time.
  13. C2 - Eingeschränkte Verwendung INA x PREDICTIVE MAINTANANCE INA tests the robustness of the network without your help. And helps to combat neuralgic points. • A virtual network engineer (Chaos Monkey) will run continuously in the background and randomly simulate failures by consecutively switching points in the network on and off. • This will identify sensitive/neuralgic points in the network. Similarly, the extent of the damage and the impact on other parts of the network will be revealed. x
  14. C2 - Eingeschränkte Verwendung INA Simulated Annealing • If you would want to assign the antenna to a yellow backbone router through the blue routers so that utilization is minimized. • There are 800bn possible combinations: 517 = 800bn • Brute force calculation of all combinations would take ~25 years if we assume 1ms per configuration. • INA’s Annealer feature automatically analyses possible routing options and suggests the best option within the tested range. • Simulated Annealing finds optimized solution within 60 s after 1000 tested combinations. AUTOMATED ROUTING OPTIMIZATION
  15. C2 - Eingeschränkte Verwendung INA A non optimal routing is selected. The Annealer starts to test other routing configurations (1000 combinations within 60s). The annealer proposes an optimized routing configuration next to the input configuration for better comparison. A data table describes the proposed changes. AUTOMATED ROUTING OPTIMIZATION
  16. C2 - Eingeschränkte Verwendung INA SUSTAINABILITY Make the network more sustainable by discovering particularly energy- intensive components, and reduce CO2 consumption in the entire network SECURITY Detection of neuralgic points in the network, which e.g. supply large parts of the population or critical infrastructures FUTURE NETWORK Change analysis, simulation and planning to verify network changes before they are applied to the network PREDICTIVE MAINTANANCE Avoid network outages and misconfigurations as mismatches will be detected beforehand COVERAGE Measure network coverage and evaluate options to reach the expansion targets and increase service quality Model further, individualized cases and find answers to questions as you need them when you need them INA‘s potential for the whole telecom business. INA's technology allows users to combine data points that help to answer very specific questions in a variety of use cases. In addition, INA offers ready-made use cases, as well as the possibility to jointly develop even more.
