History: A Slow Start… Field Deployments Started…

• Feasible, But Limited Acceptance

• Multiple Equipment Layers

• Separate Teams for Operations

• Open issues: Responsibilities and

organizational structures

• 100G integrated DWDM interfaces

• Reduced footprint, power

• Router actions triggered by optical

degradation, IP/optical coordination

Today:

Fragmented Structure of IP Carrier Networks

High operational complexity, inefficient use of capacity,

lack of scalability

Evolution:

New, Simplified Network Architecture

Integrated Packet Transport network

Simplified, lean, more scalable network structure

Three Key Elements Data Plane Integration Management Integration Control Plane Integration


ECOC 2014



Key Packet Optical Convergence Elements:Data Plane Integration


• Scope of packet optical convergence extends significantly beyond alien wavelength transmission

• Provides IP/MPLS over multi-layer transport, including:

• Regeneration and wavelength translation, physical layer planning tool integration ,

• Aggregation in different layers enabling multi-layer network optimization

Packet optical integration is field proven todayExample: IPTN field testing done by Juniper and Coriant in Q2 2014 - Kazakhtelecom

Trial specifics:• Test of commercially available 100G CP QPSK colored interfaces in Juniper PTX

via deployed Coriant hiT 7300 DWDM system

• Challenging 1575 km transmission link with many high loss spans (longer than 130km).

• 100G-optimized link design without dispersion compensation modules and hybrid EDFA/Raman amplification

for best possible transmission performance.

• Optical planning and setup of the network is

done using Coriant TransNet planning tool

Managed wavelengths:• Transport Network Management -

E2E path management of router interface

fully supported by Coriant TNMS.

• Seamless physical layer interworking

demonstrated

• Further tests planned with

line-side compatible 100G

transponders and regenerators.
