Title:

Using QoS and LiveAction to solve application performance programs across the WAN

Description:

Download the LiveAction 14-Day Trial from Applications running on today’s networks are mission critical or latency sensitive. So enterprises need to adopt QoS or Quality of Service that control how traffic is prioritized and handled during congestion. Take a look at this presentation to understand why LiveAction's QoS solution is easy to deploy, and how it provides powerful monitoring and analytics tools plus quick diagnosis of application performance issues through visual displays. – PowerPoint PPT presentation

Title: Using QoS and LiveAction to solve application performance programs across the WAN


1
Using QoS to Solve Application Performance
Problems Across the WAN
2
Using QoS to Solve Application Performance
Problems Across the WAN
Todays IT Challenges
Available Solutions
Key Considerations
3
Todays IT Challenges
Quality of Service (QoS)
Total Cost to Ownership (TCO)
Troubleshooting
Cisco Solutions
Thousands of Apps
Network Outages
  • Poor voice and video over IP
  • Poor application performance
  • Underperforming mission-critical apps (ERP)
  • Challenges of multi-site enterprises using
    constrained WAN links
  • 90 of trouble-shooting time is spent identifying
    (not fixing) the problem
  • QoS is built into Cisco routers and switches
  • Difficult to learn and deploy
  • Time consuming and error-prone CLI
  • Business-critical apps
  • Latency-sensitive apps like voice
  • Bandwidth-hungry recreational apps
  • Apps that IT didnt authorize
  • Reduce/eliminate service interruptions
  • Human configuration errors cause 50-80 of all
    network outages
  • How do all of these challenges impact TCO?

QoS management is the collection of mechanisms
that control how traffic is prioritized and
handled during congestion
All these QoS tools rely on traffic
classification the better the classification,
the better the QoS
5
Drilling Down on QoS
With QoS
Without QoS
  • Visibility and analysis
  • Protection of real-time and high priority data
    applications
  • Free for all
  • No protection of critical data, voice or video

To make the process as manageable as possible,
QoS deployments need to take into account
  • QoS needs of the organization
  • Current network architecture
  • Applications used by the staff
  • Traffic running over the network
  • QoS capabilities available in the network devices

6
Key Considerations
Ease of use
  • Look for these capabilities
  • Visual Visio-like diagrams but with real-time and
    historical flows for quick diagnosis of
    performance issues
  • Full visibility into devices and policies

7
Key Considerations
Flexibility Look for these capabilities
Copy and deploy an existing policy to multiple
network devices
Deploy cloud-based and on-premise business
applications
Work in MPLS, DMVPN, Performance Routing (PfR)
and Intelligent WAN environments
Accommodate on-the-fly QoS policy adjustments
8
Key Considerations
Power of solution Look for these capabilities
Powerful Monitoring
Effective Management
Scalability
  • Deep application awareness
  • Comprehensive monitoring and analysis
  • Robust troubleshooting real-time and historical
    capabilities
  • System intelligence to facilitate creation and
    execution of effective QoS policies
  • Instant validation of QoS policy changes
  • Fast resolution of application performance issues
  • Synthetic traffic generation and analysis for
    measuring the impact of QoS policies in a
    controlled manner
  • Thousands of network devices and millions of
    flows per second
  • Works with Cisco advanced technologies

Finding the Best Solution
What to look for to find the best, most
cost-effective solution
Easy to deploy, configure, monitor and analyze -
with Cisco advanced technologies such as QoS,
Medianet, PfR, AVC, AX, NetFlow and FnF
End-to-end flow visualization for a holistic view
of the network
Quick diagnosis of application performance issues
through visual displays
QoS graphical control to troubleshoot and fix
issues
Instant validation of QoS policy changes
