VERISIGN® DYNAMIC TRAFFIC MANAGEMENT
INCREASE AVAILABILITY, IMPROVE USER EXPERIENCE, AND OPTIMIZE GLOBAL LOAD
BALANCING IN THE CLOUD
The longer your website visitors have to wait for your site to
load, the less likely they are to stay on your site. This could
result in lost revenue and brand value, all for something
that could be easily avoided. Global load balancing in
the cloud is an effective and efficient way to boost your
site’s performance, improve user experience, increase
availability, and help protect your DNS infrastructure from
DDoS attacks.
Complex, global website traffic is commonly managed
today utilizing a hardware-based solution. The costly
combination of the initial capital outlay, operational
maintenance, future skilled staffing requirements makes
this an expensive and complex approach to effective
traffic management. This approach also increases your
risk of downtime due to DDoS attacks.
Verisign Dynamic Traffic Management (DTM) in the cloud
is designed to meet the complex needs of organizations
like yours. Verisign puts the power at your fingertips to
dynamically improve Internet service performance and
availability utilizing rules-based scripts with virtually
unlimited options for customization.
GLOBAL TRAFFIC MANAGEMENT IN THE CLOUD BEST PRACTICES FOR MANAGING YOUR COMPLEX
NETWORK NEEDS
The easily deployable Verisign DTM enables you to use
any relevant data, including performance metrics, to direct
Internet traffic using scripts tailored to your company’s
needs. With Verisign DTM you can choose the appropriate
Content Delivery Network (CDN) based on dynamically
updated information, including time-of-day and geographic
pricing. The possibilities are nearly endless, enabling
your organization to direct traffic based on virtually
unlimited criteria.
Additionally, Verisign DTM will help protect your
organization from the risk of outages caused by DDoS
attacks. Verisign DTM is built on our proven, globally
deployed and secure DNS infrastructure. Our DTM solution
is delivered through the value-added service options of
Verisign Managed DNS, specifically:
•• Weighted-Load Balancing
•• Geo-Location
•• Failover
As depicted in the graphic on the next page, end users are
directed to a data center or cloud platform based on your
business rules as captured in a DTM script. Multiple factors,
such as, performance metrics, CDN pricing, user location
or nearly any other enterprise criteria can be scripted to
determine DNS responses.

STANDARD TRAFFIC MANAGEMENT SERVICES
For organizations with basic traffic management needs,
Verisign also offers a set of standard, cloud-based traffic
management services that provide all of the availability,
performance, DDoS-attack resilience and scalability
benefits of Verisign DTM without the dynamic capabilities
of script-based traffic rules.
Standard traffic management services all utilize a
static configuration model to realize custom scenarios
determined prior to deployment. The services include:
Failover: Helps you avoid outages by routing users around
slow or inoperable sites. The service monitors websites
or Internet services using a variety of protocols, including
DNS, Ping (ICMP) HTTP/HTTPS and SMTP, to determine
system health and provide a back-up answer in response to
queries when the primary service is unavailable.
Geo Location: Enhances user experience by reducing
latency and increasing uptime. Geo Location globally
directs Internet traffic among worldwide data centers,
CDNs or cloud platform providers and also delivers a DNS
response based on the recursive resolver’s geographic
location. The service also enables the delivery of locationspecific content.
Weighted Load Balancing: Enables you to optimize
infrastructure usage by balancing end-user traffic among
multiple data centers by specifying the relative amount
of traffic each server should receive. When this service is
activated, the service responds with different authoritative
DNS responses each time a particular query is received in
proportion to the weights you specify.
IMPROVE WEB PERFORMANCE WITHOUT
SACRIFICING CONTROL
Whether your company is utilizing Verisign Dynamic Traffic
Management or standard traffic management, you can
rest easy knowing that you’ve trusted your unique traffic
management processes with a proven, trusted service
provider. Our vastly deployed, global, traffic-management
services will improve your organizations’ flexibility,
capacity and control, while lowering your total cost of
ownership and improving end-user experience.
