Integrated packet transport (IPT)

Deliver superior carrier Ethernet services via a packet-optimized WDM/OTN network

Why Ethernet over optical?

As data traffic continues to grow at around 30% annually, it is critical that network operators modernize their networks to reduce the transport-cost per bit, conserve space and power, and lower operational costs — all while improving network performance.

Achieving this efficiency entails a tight integration between the packet and the optical layers. The optical layer offers the lowest cost per bit while the packet layer offers granular service delivery. With packet-optical integration, you benefit from the best of both worlds for optimal use of transport network resources.

How can packet-optical transport help you meet growing demand?

To meet growing demand for Ethernet-based cloud, mobile, and video services, you need a packet-optimized optical network. Our Integrated Packet Transport solution keeps you ahead of the demand curve. Architected for network modernization, it delivers the capacity, flexibility, and packet feature richness you need to handle unrelenting traffic growth.

Adding Ethernet switching and aggregation to the Nokia 1830 PSS/PSS-x WDM/OTN platforms, the converged packet-optical solution optimizes wavelength capacity. It enables flexible grooming of services by switching at the wavelength (L0), sub-wavelength (L1/OTN), or packet (L2/Ethernet) levels. It provides the scale to address more capacity and delivers efficient and versatile traffic aggregation. The solution cost-effectively delivers emerging and existing services from the access edge and metro edge to the core. 


Integrated Packet Transport

Easily introduce new applications and services leveraging a fully managed, end-to-end packet solution

With our comprehensive packet-optical solution, you can provide feature-rich and reliable packet transport services. It leverages the power of our Service Router Operating System (SR OS) to create a fully managed, end-to-end packet solution across our optical and Ethernet/IP/MPLS portfolios.

The advanced high-availability features of SR OS enable resilient carrier Ethernet services. The SR OS features include multi-chassis link aggregation, multi-chassis automatic protection switching, Ethernet ring protection, and MPLS-TP protection switching.

The solution is based on scalable packet-optimized WDM/OTN. It uses a field-proven layer 2 transport architecture benefiting from common service, operations and management. This makes it easy for you to introduce new applications and differentiated services from the customer edge to aggregation and the core.
