NFV Brings New Levels of Flexibility and Optimization
Collect
• Cost drivers
• Technical metrics
Analyze
• Model the options
• Optimize
Act
• Move
• Re-deploy
• Scale …
Creates an opportunity to consider both QoE/QoS & financial optimization
• Project leverages analytics and
policies that dynamically
determine orchestration
decisions to make more well-
rounded NFV instantiations
• We show a closed-loop
system from mediation,
monitoring, optimization
analytics through policy-driven
instantiation and restoral
considering QoE/QoS and
financial metrics Goal is to optimize business value dynamically

Multi-dimensional Optimization is Key
Optimization
Policies
• Global clauses
• Financial clauses
• Service clauses
• Customer clauses
Cost Drivers
• Compute
• Storage
• Network
• Power/Location
Technical Metrics
• QoS
• CPU
• Memory
• Network bandwidth
Business
Impacts
• QoE
• SLA violations
• Services
• Operations
Policies account for
these diverse set of
objectives to drive
optimization decisions
Optimize against a wide
range of financial and
technical objectives
Decisions are geared toward
attaining a level of business
agility not possible before

Examples of Financial-based Optimization
Triggers
• Time of day power tariff change - As a result the cost of placement for services would force the move to
another data center
• Cache resources become available - Low-cost disk caching becomes available so some services could move
because the transport-cache equation changes
• Margin optimization - Service revenue for some services changes, maybe due to a marketing campaign, and as a
result we move these services
• Cost creep - The cost of capacity has increased over time and a global optimization (which is being run in parallel)
identifies a +X% benefit to a global optimization so services are moved
• Service protection change - A service is now offered at a higher revenue because of improved protection
requirements which changes the overall cost dynamic

Architecture & Process Enhancements
• Explores cases where competing policies need
to be reconciled to make optimization decisions
‒ With inclusion of QoE and financial data,
optimization/analytics becomes multi-faceted and
dynamic
‒ Multiple kinds of optimization may need to be
reconciled (finance, CEM, network/data center) by the
decision engine
• Improves the intelligence of the closed-loop
control system by involving financial support
systems
‒ Understand the financial elements that make up the
cost and revenue components of service offerings
• Decision engine may be human-assisted – in
particular when handling exceptions
• This phase looks at new metrics, policy model
extensions and optimization algorithms

Policy Modeling
Information modeling aspects of policy management
‒ The Catalyst team is working on the underlying policy model to abstract policies that
govern various system operations, starting from regulating QoE to configuring and
securing the cloud as a whole in addition to its individual tenant virtual infrastructures
‒ Another challenge being addressed is the complexity of B2B2X ecosystems where the
policies of various actors need to work in concert with global policies required to assure
the smooth end-to-end delivery of cloud services
‒ Looking at the Information Framework as enhanced for ZOOM to see how to
accommodate multiple and potentially conflicting policies. This work is being
incorporated into a policy dashboard that will be part of the prototype shown in Nice
next year.
