Introduction Network topology evolution Traffic characteristics Ethernet service origination Summary


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

Requirements


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
