Cloud Service Provider and Cloud Consumer Requirements

Cloud Service Providers want to:• Migrate VMs, on demand, to any DC based on:

– Available DC capacity, WAN BW, WAN Delay, etc.

• Query WAN to make informed DC route selection • Use WAN as if it were DC LAN

Enterprise Cloud Consumers want to:• Increase/Decrease WAN bandwidth

– just how they increase/decrease CPU and storage for VMs with IaaS

• Use Bandwidth on Demand above a minimum CIR– Short term increase in CIR or EIR bandwidth

Ethernet Services alignment with CloudCurrent and future directions

What most Ethernet Service Providers offer today:• Fixed bandwidth Ethernet services

– Takes weeks or months for subscribers to add bandwidth

• New long term contract required for higher bandwidth– Delays buyer’s purchasing decision for higher bandwidth

• Service Provider customer portals are closed systems– No APIs for Customer’s apps to query network or request changes

Ethernet Services Evolution• Bandwidth on Demand (BoD)

– Increase CIR or EIR– On Demand or through Reservation

• Open APIs to create Network as a Service (NaaS) ala IaaS– Web2.0 RESTful APIs agnostic of networking technology– Customer’s applications query network or make service changes



BoD provides more Ethernet Service Revenue - soonerOpen APIs enable Application/Service Innovation and Differentiation

Customers want to purchase Ethernet WAN services based on capabilities, not technology


FundamentalCapabilities

Ports (UNIs/ENNIs)• 10/100Mbps• 1Gbps, 10Gbps• 100Gbps

Connectivity of Ports (EVC)• Point-to-Point • Any-to-Any (Multipoint)

– 3 or more locations

Bandwidth of EVC• Line rate of port• Sub-rate (CIR < Line Rate)

– 400Mbps on a 1Gbps port

DifferentiatingCapabilities

Service Availability• MTTR• Protected or Unprotected

Service Multiplexing• Port-based service

– Single service (EVC) per port• VLAN-aware service

– Multiple services (EVCs) per port

Classes of Service Service Performance

• Frame delay• Frame Loss

How Ethernet Services Are Sold Today

Services typically defined by their transport technology• Ethernet over SONET (EoS) service• Ethernet over WDM (EoWDM / Eoλ) service• Ethernet over TDM/PDH (bonded T1s) service• Ethernet over Copper/DSL (EoC) service• Ethernet over Fiber (EoF) service• Ethernet over MPLS service (VPWS, VPLS)

Customers must sort through many technology choices• They simply want to specify their service requirements• These choices complicate their purchasing decision

How does a service provider meet customer needs over a diverse set of transport network assets ?


Ethernet Service Delivery using Packet Optical Networking

Packet Optical Networking Platforms• Meets stringent performance required by Cloud Services, MBH• Unified Management from Photonic layer through Ethernet layer

Deliver any MEF service (E-Line, E-LAN, E-Tree, E-Access) over any transport technology• Leverage existing network assets

• E-Line, E-Access, E-LAN and E-Tree services using any mix of: – Ethernet over Fiber (EoF) – Ethernet over SONET/SDH (EoS)– Ethernet over PDH (EoPDH)– Ethernet over Copper Access Networks (EoC)


MEF Services should not be limited by Transport Technology
