What You Want…
• Pick up the phone and you get dialtone. Flip a
switch and lights turn on. Go to a web site and …
oops … not as predictable.
• Businesses need control over their Internet sites.
Revenue, profitability and reputation depend on
control of Internet site availability and
performance.
QUESTnet Toowoomba, June 28, 2000
Dollars are more liquid than ever
• The Internet makes purchases or movement of
capital in general more liquid than ever before in
history
• Mouse click is more convenient than a drive
across town or a flight around the world
• Building brand is critical for long term success
• Long term “sticky-ness”
– Serving an existing customer is less expensive than acquiring new
ones
QUESTnet Toowoomba, June 28, 2000
How to retain more liquid
• Must build infrastructure to support capturing &
retaining customers
• Many approaches
• Focus on the infrastructure required to deliver
“Internet Quality Control”
QUESTnet Toowoomba, June 28, 2000
What turns a site “off” or makes it
leak
•
•
•
•
•
•
Too much traffic
Hardware failure
Operating system failure
Application failure
Content failure - sending out “error” messages
Network outage

Local Area Traffic - Server
• Basic mismatch between growth of server
capacity & network capacity
• Moore’s Law vs. Gilder’s Law

QUESTnet Toowoomba, June 28, 2000
•
Processor capacity doubles every 18
months - Moore’s Law
•
Network traffic doubles every 100
days - Gilder’s Law
•
Servers do not accommodate bursty
traffic
•
A new server with 4x performance 810 times as expensive
•
Skilled technical personnel are
scarce and expensive
Server
Old way
• Buy a bigger server
New way
• Use Intelligent Load Balancing technology & buy
multiple smaller servers
QUESTnet Toowoomba, June 28, 2000
Intelligent Load Balancing
• Virtualizes multiple devices
– Virtual Resource Management
– Internet Traffic Management
• Intelligently distributes traffic
• Insulates users from problems
Servers
Caches
Firewalls
QUESTnet Toowoomba, June 28, 2000
Traffic
Issues to Consider
• How availability is determined
– Are applications sending the “right” answer
• Methods to maintain persistence
– Must dovetail with application state awareness
– Address concentration & jumpy source address
– Proxies,
• Load balancing methods
• Security
• Other value added services
– Rate shaping
– Packet filtering
QUESTnet Toowoomba, June 28, 2000
Business Reasons to Implement
• Assures the store is always open for business
• Customer Retention
• Site can offer the appropriate level of
access/service based on the customer
relationship
• Provides predictable transaction completion
• Maximize return on investment from existing
assets
– Allows a site to easily scale to meet growing demand
• Enhances customer experience
– Fast access
– Consistent response time/content/service
– Delivery of the right content

Network
• Once Server solution is in place, next challenge is
the network
QUESTnet Toowoomba, June 28, 2000
Network - Driving Factors
• Address disaster recovery
• Give the best experience to the end user
–
–
–
–
Minimize network response time
Localize traffic
Reduce Costs
Provide predictable response to end users
• BRAND - present single presence to the world
QUESTnet Toowoomba, June 28, 2000
Network
• 25% of customers currently depend on
globally distributed data centers.
• 2/3 of single site customers intend to move to
globally distributed data centers within a
year.
QUESTnet Toowoomba, June 28, 2000
Network
Old Way
• Manual selection by end user
• Round robin DNS
• Router metrics
New Way
• Intelligent Wide Area load balancing
– Stretch the LAN solution over the WAN
QUESTnet Toowoomba, June 28, 2000
Intelligent WAN Load Balancing
• Virtualizes multiple data centers
• Intelligently distributes traffic
• Insulates users from problems
QUESTnet Toowoomba, June 28, 2000
Issues to Consider
• Direct traffic to the best performing site based on
both site & network metrics
• Deciding based on one without the other results
in poor customer experience
– Network great but servers down = lost customer
• There is no single metric that can be used to
distribute traffic effectively. A combination
approach works best
– Site - throughput, servers available, connections
– Network - round trip time, packet loss
– Preferred site based on Topology or Disaster Recovery
QUESTnet Toowoomba, June 28, 2000
Network - Business Reasons to
Implement
• Business continuity - guarantees site is always
“ON”
• Provides users with best experience
• Enhances brand in market
• Reduces costs
– Local disk cheaper than transport - similar to decision to cache
• Regain control

In solving the Server & Network problems a third
challenge is created
• Users can be directed to any data center
• Users can be directed to any server
• How to manage all the files required to deliver the
“right” response to users
QUESTnet Toowoomba, June 28, 2000
Content
Old way
• Solutions to date have been “roll your own”
• Winner for best name so far… “Grunt”
• Labor intensive
New way
• Automated Content Management
QUESTnet Toowoomba, June 28, 2000
Content
• Must be compatible with existing content creation
tools
– Facilitate distribution & management of files
• Must provide roll-out & roll-back mechanism to
far-flung resources
• Interact with Local & Wide Area components
• Ease burden on technical staff resources

Summary - Internet Quality Control
• You must first guarantee availability of server,
network & content
• Once the base guarantee of “on” is in place then
start treating people & traffic differently
• Establish business policies & have the
components of your Internet Quality Control
system work in concert to enforce them
