MSPPs provide no Ethernet aggregation• EoS is a port-based service
But.. Additional NEs needed to complete the solution Ethernet Switches
• Aggregate EoS traffic to single router port EoPDH Gateways
• Ethernet over bonded T1s/T3s

Packet Optical Networking Platforms Why do we need them ?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

When most think of Ethernet, they think of Ethernet LANs Technically referred to as Connectionless
Ethernet
CLE is also used in Carrier Networks Subscriber sites (many users) connect to an

Connectionless Ethernet limiting factors in Carrier Ethernet networksConnectionless Ethernet limiting factors in Carrier Ethernet networks
Non-Deterministic QoS and Traffic Patterns Traffic path highly variable due to spanning tree topology changes Creates variable QoS performance (Delay, Delay Variation, Loss) Difficult to troubleshoot variable traffic paths
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) 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 worldsConnection-Oriented Ethernet (COE) The best of both worlds
Ethernet over SONET•Deterministic and precision QoS•Bandwidth reserved per STS•99.999% Availability•Highest Security (L1 service)
Connectionless Ethernet•Layer 2 Aggregation•Statistical Multiplexing•Flexible Bandwidth Granularity•Cost Effectiveness
