Traditional IP core networks must evolve to meet the growing demands for capacity and performance. With the rapid increase in traffic, the adoption of 100G and 400G technologies, and the need to phase out older equipment, the evolution of IP core networks is now more critical than ever. This transformation offers operators a unique opportunity to rethink their network strategies, optimize costs, and improve efficiency. To support this transition, detailed evaluation methods are essential to help operators choose the best path forward. Upgrading IP core networks can significantly reduce operational expenses while enabling higher capacity and better scalability. The next-generation core routing platform represents a major advancement in this area, leveraging breakthroughs in 100G Ethernet and 400Gb/s network processors. These platforms allow operators to build more efficient and cost-effective network architectures. A recent study by Bell Labs with a European operator highlighted the importance of these new platforms in upgrading IP core networks. The operator manages a large-scale, multi-layered IP core network with over 100 sites and faced three main challenges: underutilized link and node capacity, high operating costs, and the upcoming deregulation of IP peering, which would drastically increase traffic and change traffic patterns. To address these issues and achieve cost savings, the operator partnered with Bell Labs to develop optimized strategies. Three key approaches were proposed: **Strategy 1: Improve Link Utilization** Increasing link utilization helps manage high-traffic networks and reduces transmission costs with minimal impact on QoS for best-effort (BE) traffic. Critical traffic remains unaffected. The study showed that improving utilization from 50% to 67% could save 23% in transmission costs, affecting only 12% of maximum flows. Further improvement to 80% could lead to a 30% cost reduction, impacting just 18% of flows. **Strategy 2: Reduce the Number of IP Core Nodes** Reducing the number of backbone nodes lowers CAPEX and saves space and energy consumption. The study found that reducing the number of IP backbone nodes from 100 to 40 could result in 23% CAPEX savings over five years and 48% savings in space and energy use. **Strategy 3: Adopt Next-Generation Core Routing Platforms** Platforms like the Alcatel-Lucent 7950 XRS offer greater scalability and efficiency. The earlier operators migrate to these platforms, the lower their long-term total cost of ownership (TCO). Over five years, the new platform will occupy one rack at most IP core sites, while traditional routers would require additional racks, leading to faster deployment and reduced maintenance costs. These strategies demonstrate how modern IP core networks can be transformed into more efficient, cost-effective, and future-ready infrastructures.
