Clients require a fast way to respond
to their market demand
• Today it takes days. For example, at
OFC 2013 Cisco’s SVP of IT, John
Manville stated it takes Cisco’s IT 5
days to fully bring a multi-tier
workload on-line, includes:
configuring network appliances,
storage,etc…
• For this example to be possible, 5 days
needs to be 5 minutes or less.

Cloud needs elasticity and multi-tenancy
Big Data & Analytics needs Application controlled, optimized fabrics
Mobility needs guaranteed end-to-end SLA
DC Virtualization needs agility of a fully virtualized environment
Why is the Network usually a boat anchor in today’s data center?
Today’s Data Center Network
often gets in the way of client trends
Today’s protocols make multi-tenancy complex.
Box-level services & discrete physical infrastructure prevent true elasticity.
Network virtualization is lagging other parts of DC Infrastructure.
Complexities of physical network (box-type, SW version;
capabilities; vendor inconsistencies) drag agility.
Box-by-box protocols and behavior prevent anything end-to-end
and results in error-prone security and QoS
Closed networks cannot be programmed via business applications,
resulting in under-utilized networks.

Virtualization and Beyond

What is SDN?
• Today, routers control themselves, passing messages
between them
• SDN separates the Control and Data planes
• A separate, centralized controller then takes command

Do we want Distributed or Centralized?
14
• Ethernet topologies were built
distributed
Scalable but hard to monitor
• Openflow topologies (today) are
centralized
Control-data separation forces this model
Strengths of one approach are weaknesses of the other
Centralized is better suited for modern cloud applications
IBM System Networking

Better topologies
• Multi-tiered tree topologies
• High oversubscription
• Expensive, high bandwidth uplinks
• Robustness of higher tier product
has been a concern
• 2-tiered mesh or Clos topologies
• Oversubscription only to WAN/core
• Large cross sectional bandwidth
(TOR bandwidth is cheap)
• Mature Layer 2/3 softwareIBM System Networking

SDN in a Single Sentence
• The hope/expectation of better efficiency/utilization through
identifying flows of packets and making smarter holistic decisions
• A good analogy would be the Air Traffic Control system

Packet or Flow Switched?
• Ethernet topologies are packet
switched
Statistical link utilization
• Openflow topologies (today) are
flow switched

…but what about:
• Billing
• Carrier interworking
• Stacking of SDN controllers
• Oversubscription, lack of resources

Metro connectivity:
• Data center distances < 100km
• Ethernet, Fiber Channel, some Infiniband
• DWDM w/ minimum processing (latency)
Optical Network Virtualization
Core connectivity:
• Globally distributed data centers
• IP/MPLS over OTN/DWDM
• Standard core network technologies

Optical transport and SDN
• Decades of work have yielded today’s agile core networks
• Unfortunately, the information to make intelligent decisions resides
at higher layers
• Problem is made worse by today’s flow dominated traffic

Optical transport and SDN
Direct vs Indirect Model
• How to best extend SDN to transport layer?
• Direct control yields most potential benefits at cost of complexity and
latency
• Indirect control is easier to implement, and provides a migration path

high-bandwidth, low-latency connectivity on demand.
• Different models for optical network virtualization exist.
• A compromise between hiding the optical complexity and
exposing the optical topology is required.
