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

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

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)
