Enterprise Cloud Service delivery Challenges
• Today, Internet is predominant WAN to deliver cloud services
– Surprising, little attention paid to it by the Cloud Community
• Larger Enterprises hesitant to move mission-critical
applications to the cloud when delivered via the Internet

Carrier
The intermediary that provides Carrier Ethernet
connectivity and transport of cloud services from Cloud
Service Providers and Cloud Consumers and with other
Ethernet Cloud Carriers.
Cloud
Broker
An entity that manages the use, performance and
delivery of cloud services, and negotiates relationships
between Cloud Service Providers, Cloud Consumers and

Cloud Broker Definition Clarification
• NIST Cloud Broker Definition is very generic
– Appears to assume only Internet WAN connectivity
• New MEF white paper defines more use cases
– Ethernet Cloud Carrier acting as a Cloud Broker
– Cloud Service Provider acting as a Cloud Broker
– Cloud Broker

wholesale services to
Ethernet Cloud Carrier
• Business relationship between Ethernet Cloud Carrier and
Cloud Consumer
– Ethernet Cloud Carrier wholesales cloud services from Cloud Service
Providers
• In telecoms industry, this Cloud Broker analogous to telecom
service provider delivering Internet access services
– Telecom SP provides network connectivity to customer premises
– Telecom SP provides Internet access service like an ISP

Cloud Service Provider acting as a Cloud Broker
• Cloud Service Provider has business relationship with Cloud
Consumer
– Cloud Service Provider wholesales network connectivity from Ethernet
Cloud Carrier
• In telecoms industry, this Cloud Broker is analogous to an ISP
– ISP wholesales access network connection from incumbent telecoms
service provider who owns access lines to the customer premises
– ISP provides network connectivity to customer premises and Internet
access service

• Cloud Broker has business relationship with Cloud Consumer
– Cloud Broker wholesales network connectivity services from Ethernet Cloud
Carrier and cloud services from one or more Cloud Service Providers
• In the telecoms industry, this Cloud Broker is analogous to a
mobile virtual network operator (MVNO)
– MVNO sells cellular voice/data services but does not own/operate a cellular
wireless network

Use Cases for
MEF E-Line, E-LAN, E-Tree Services
Carrier Cloud Forum – February 13, 2012 – Santa Clara, CA

MEF E-Line (EVPL) Use Case (Point-to-Point)
• Private Cloud, Community Cloud or Hybrid Cloud WAN Solution
• Hub UNI at Cloud Service Provider Primary Data Center
– Aggregates all EVPL EVCs from Cloud Consumers
– Able to add additional Cloud Consumers on same hub UNI
• Secondary data center reached through DC-to-DC EVPL EVC

MEF E-Tree Use Case (Point-to-Multipoint)
• Private Cloud, Community Cloud or Hybrid Cloud WAN Solution
– Cloud Consumers can access either data center
– Ability to add additional Cloud Consumers to existing EVC
• E-Tree EVC Data Exchange Rules
– Leaf UNI to Root UNI
– Between Root UNIs

New MEF standards development:
On-Demand, Elastic Ethernet Service Attributes
Carrier Cloud Forum – February 13, 2012 – Santa Clara, CA
17
Ethernet Service Attributes being Evaluated to Better
Support Cloud Applications
• Elastic Ethernet Service Attributes
– On-demand change of EVC or UNI attributes for a specific time period
• Once time period ends, revert back to their prior state
• Investigating on-demand and reservation models
• Example Elastic Attributes
–
–
–
–
Increase CIR of existing EVC
Add a new EVC over an existing path
Modify CoS of existing EVC
Add or Remove UNI endpoints in an EVP-LAN, EVP-Tree or Hub &
Spoke EVPL service
• On-demand bandwidth approaches
– Based on bandwidth usage (X MB/month)
– Based on CIR and/or EIR (200 Mbps CIR and 400 Mbps EIR)
• Network/Cloud/Subscriber Management Orchestration
– End-to-End service management and SLAs
