Ethernet servicesmarket opportunity
Enterprises need more bandwidth to more locations Bandwidth demands are increasing at every site Facility expansions create larger metro campuses National and global facility expansions are growing
Enterprises need more applications and more simplicity Ethernet has a strong familiarity and preference Bandwidth upgrades without hardware change Buying managed services helps the outsourcing trend
Enterprise see more cost-effective alternatives Internal network analysis shows dramatic value gains Legacy services under transition to private networking solutions Creative budgetary approaches underway with productivity

Storage servicesmarket opportunity
Enterprises need higher levels of business continuity Data security becomes mission critical Network downtime costs can be devastating New government regulations (Basel and SEC) are mandating
recovery times and security distances
Enterprises need higher access speeds and distances Increasing storage volumes and access demands Increasing distances, turning SANs into MANs and WANs
Enterprises need higher flexibility and more locations Storage environments and applications are increasing New out-of-city facility savings programs drive more sites

Dynamic vs. static advantages
Common metro WDM advantages
Static WDM advantages
Dynamic WDM advantages
Service flexibility from 10M to 10G+ per service
Network flexibility from pt-pt, linear ADM, ring
Distance capabilities from 1 to 600km+
Scalability from 1 to 64ch+
SONET/SDH and Ethernet integration options
Lower 1st installedcosts (3-10x)
Lower equipment cost/service (2-5x)
Simpler installation & maintenance
CWDM & DWDM flexibility
Mesh support (Degree-2+ connectivity)
Enables shared protection and mesh topologies
Increased planning flexibility
Faster incremental service turn-up
Simpler service upgrades
Lowest service costs = CAPEX
Highest service flexibility
Highest provisioning flexibility = OPEX

Ethernet service creation
Many 100,000s of service defining devices Edge routers, B-RASS, etc. Management challenge (maintain, operate, upgrade, etc.)
Service origination in scalable service-oriented platform Centralized, easy-to-upgrade, scalable service originating equipment that takes advantage of economies of scale.
Distribution in cost-efficient carrier-class distribution platform Service agnostic/future-proof Carrier-class reliability, management, and performance monitoring.

Access network challenges
Characteristics
Topology Very large number of devices Evolving network Short distances
Service customization Large and increasing range
of services (apps., protocols, speeds, etc.)
Cost sensitivity High; little sharing
Efficient operation Easy/no set-up No troubleshooting No service dependent upgrades
“Carrier class” Rate shaping Protection options Performance visibility
Cost-efficient Delivery platform: service agnostic Small form factor: “Pizza box” Interfaces: S/XFP, RJ45

Summary
Network topology considerations CWDM & DWDM flexibility Simpler installation & maintenance Mesh support (Degree-2+ connectivity)
Traffic pattern considerations Static/slowly changing demands:
Customer base: few but large Key requirements: reliability, performance guarantee Cost sensitivity: medium and mostly on BW/$
Variable demands: Customer base: many but small Key requirements: service options Cost sensitivity: high on both first install and BW/$
Access network requirements Differentiated service options
Rate shaping Protection options Performance visibility
Cost-efficient Delivery platform: service agnostic Mass market concept
Efficient network operation and maintenance
