Introduction

• Telco industry needs to steer away from "dumb pipe provider" concerns and focus on smart networks

• Business reality presents large challenges and opportunities

• Smart telco networks are about extracting higher business value from network infrastructure – via Network Intelligence layer

4G Business Challenges and Opportunities

• Faster pace of business with more dynamic & complex network– Smartphones– Device-based applications– Femtocells

• Enhaced service quality and customer experience

4G Business Challenges and Opportunities

• Increased regulation– Higher operations visibility– Restrictions while driving

• Interaction with other complex systems– Transportation– Power grid– Social networks

Need for Network Intelligence layer

• Extract higher business value from network events in realtime via:– Continous monitoring– Simplified integration of network and

business application layers – event-driven– Connecting dots in realtime – correlation

Network Intelligence builds on:

• Business Intelligence• Performance monitoring• Traffic monitoring• Fault management• Policy-based management • Deep Packet Inspection (DPI)

Network Inteligence adds:

• Sharing of events across management silos

• Connecting dots in realtime – event correlation

• Integration of business processes with network operations processes

• Event-driven architecture

SLA management use case - consumer mobile broadband

access• Service level guarantees: throughput, packet loss, latency, jitter

• Monitoring via: DPI, device agent• SLA tracker – detects SLA violation events• Integrates: CRM, billing, device

management, service portal, data warehouse

Service restriction while driving use case

• Block usage while user is in a moving motor vehicle

• Monitor: device location, vehicle device presence

Service problem monitoring via social networks

• Identify potential service problems by from patterns of communication in social networks such as Twitter

• Search for keywords related to service problems, track over time and location

• Generate trouble investigation events

Technologies and Products for Network Intelligence

• Event stream processing – Complex event processing (CEP)

• Application servers• Messaging middleware• Data caching – fast access to state info• Databases

Event producer

• Simplified integration via decoupling between producers & consumers

• Producers don't know about consumers and viceversa

• Events are common info• Horizontal scaling

Conclusions

• Smart not dumb networks – higher complexity of network infrastructure

• Extraction of higher business value from network requires new functional layer – Network Intelligence (NI)

• NI offers simplified integration via Event-driven Architecture

• NI enables realtime analysis via Complex Event Processing
