“BIG”Messages
• Slow Growth throttles Network Transformation• Packet Tandem not carrying Packet Local• Cornucopia of Services emerging slowly• Challenging Mass Market Forces• Enterprise Opportunities gaining credence• Operations could easily gate progress
Slow Growththrottles
Transformation
• Business Cases Driving Reuse of Current Assets– What Services Require Next Generation Elements?– Moore’s Law Creating Excess Capacity – Local Competition Creating Excess Capacity
• Transformation Investments Facing Real Hurdles– Emerging Nature of Products & Standards– Need “IP to the Edge” & QoS to Enable New Services– Operations Investments A Major Barrier
Packet Tandemnot carryingPacket Local
• Cost Reduction Compelling at Tandem Level– Internet Call Diversion & Packet Voice Tandem– Cost Reduction Impacts Definitive
• Revenue Generation Unproven at Local Level– New Service Enablers – SS7 Analogy– AIN 0.0/0.1/0.2 versus AIN 1.0 Analogies– Elusive Feature Parity Considerations– IP Access to the Edge
Cornucopia of Services
emerging slowly• 3rd Party Services Explosion Remains Elusive• Application Service Provider Model Unproven• “Internet Valuation” of Consumer Data Services
• Realistic Assessment of Feature Take Up • Softswitch Primary Value is IP Endpoint Access• Need to Cope with Architectural Complexity
ChallengingMass Market Forces
• Compelling Consumer Service Offerings - ???– Unified Messaging & Presence – Utility -?– Home Networking - Complexity & Slow Uptake -?– Voice Portals – Early Stage-?
• Wireless Growth– Wireless Messaging, Paging & Short Message Services
• Exception with Greatest Potential: ADSL– Voice over Broadband; Internet Access; Interactive
Gaming; Video over DSL; Streaming
Enterprise Opportunities
gaining credence
• Most Promising Services -> Enterprise– IP Centrex; Virtual Private Networking; Work at
Home; Unified Messaging; Teleconferencing• More Sophisticated End-users and administrators• Data Networks In Place to Subsume Voice Traffic
Operations could easily gate progress
• End-User Self-Provisioning Explicitly Assumed– Administration versus Activation & Billing– Complexity of PC System Administration
• History Repeating Itself– Little Industry Focus on Network/Service Operations– Mass Deployment Likely Requires BIG Operations
WhatNext?
• Maintain Present Approach to Enterprise Space• Address Consumer Space with Applications:
– That Bond Customers to the Service Provider– That Leverage Broadband Capability & Investment
• Identify Incremental Solutions to Gain Funding• Invest Energy in Operations Technical Planning
