Packet Optical Networking Platforms
Why do we need them ?

Metro Networks originally unified with SONET/SDH

Metro networks dis-integrated as IP services dominated


Aggregation: Mix of SONET/SDH, Switch/Router, PDH Gtw NEs
Transport: ROADM / DWDM
This “dis-integration” resulted in large CapEx and OpEx


Cost to evaluate, deploy, operate and interconnect multiple NEs
• Cost of multiple vendors to manage


OAM costs (provisioning, troubleshooting)
Reliability (SLAs) impacted due to more points of failure
• More NEs, more cables, etc.

Different network operations for aggregation and transport
• Different OSSs, skill sets, management methodologies
Packet Optical Networking Platforms “re-integrate”
aggregation and transport networks

Connection-Oriented Ethernet
Connectionless Ethernet (CLE)

When most think of Ethernet, they
think of Ethernet LANs


Technically referred to as Connectionless
Ethernet
CLE is also used in Carrier Networks

UNI
UNI
Subscriber sites (many users) connect to an
Ethernet UNI
• Instead of a single user connecting to an
Ethernet port in a LAN

Connectionless Ethernet limiting factors in
Carrier Ethernet networks

Non-Deterministic QoS and Traffic Patterns




Inconsistent Bandwidth for Subscribers



Ethernet MAC Address learning performed dynamically through
broadcasting of unknown address to all ports (called flooding)
Flooding takes away from revenue-generating bandwidth
Difficult to Guarantee Bandwidth (Traffic Engineering)


Traffic path highly variable due to spanning tree topology changes
Creates variable QoS performance (Delay, Delay Variation, Loss)
Difficult to troubleshoot variable traffic paths
Multiple source and sink points in the network
Difficult to provide High Network Availability

Spanning Tree variants cannot meet demanding service requirements
CLE requires technology augmentation to make it “Carrier Grade”

Connection-Oriented Ethernet (COE)
The best of both worlds
Connectionless Ethernet
• Layer 2 Aggregation
• Statistical Multiplexing
• Flexible Bandwidth Granularity
• Cost Effectiveness
Ethernet over SONET
• Deterministic and precision QoS
• Bandwidth reserved per STS
• 99.999% Availability
• Highest Security (L1 service)
Connection-Oriented
Ethernet
COE makes Ethernet more like a Layer 1 service
but with all the benefits of Layer 2 Ethernet

Why COE ?

Makes Ethernet more like SONET which dominates metro
networks today



Network operations procedures similar to SONET
Smoother transition for SONET-trained operations personnel
Highly scalable packet-centric technology



COE delivered over:
• SONET/SDH, PDH, OTN, WDM, Fiber (native Ethernet)

Ideally suited for:



Metro Ethernet Aggregation for handoff to IP service edge networks
Mobile Backhaul Networks
High Performance Ethernet Private Lines (EPL), Ethernet Internet
Access and Layer 2 VPNs (EVPL) commercial business services
COE evolving Metro Network to be more packet-centric
while leveraging existing TDM infrastructure and operations
