  • Are you getting an acceptable ROI for your network?
application traffic management visibility

“After the Packeteer deployment, we saw it all. NetBIOS, FTP, and other important, but not time-sensitive, applications were running rampant over the financial transaction applications delivered over Citrix, crushing the sessions and delaying transactions.”

Matt Matin, Systems Engineer, LandAmerica

Application Traffic Management: Visibility

Visibility

  • Knowledge is power
    • Determine what applications are running on the network.
    • Track how much bandwidth are they using.
    • Measure delay, application response times & Slaps.
    • Track, troubleshoot, manage
visibility advanced application intelligence classification
VisibilityAdvanced Application-intelligence (Classification)
  • Automatic Traffic Classification
    • AutoDiscovery automatically classifies & measures traffic
    • Simple configuration: Basic IP Settings
    • Application classifications
    • ATM, Frame Relay, IP, MPLS, Ethernet link classification intelligence
  • Application-intelligent
    • Advanced application intelligence - Layer 7 across multiple packets with behavioral intelligence
    • Shifty peer-to-peer applications, which port hop and masquerade
    • Stateful applications which dynamically negotiate ports
    • Custom definitions extend Layer 7 classification to thousands of applications.

Network Performance Monitoring

    • Analyzing efficiency on the XXX network
  • Efficiency
    • Identified recurring drops in overall efficiency
    • Took a closer look at DCOM (MS Mail) efficiency

Malicious and Recreational Traffic
  • Even well designed networks are subject to attacks and congestion
  • Worms and viruses
  • Major software updates
  • Web traffic from major news events
  • Rich/streaming media and P2P
  • Internet radio
  • Large file transfers and email attachments

Network Performance Monitoring

    • Identifying a virus or Denial of Service type attack on XXX network

Inbound Top 10 (From Remote to Core)

  • Top Talker
    • XXX.X.48.53 (smalltic1) = 99%

99% of the ICMP traffic is a single Client!

ICMP Utilization

  • Traffic History
    • Performed “Traffic History Recent” command for the created class “outbound/icmp/smalltic1”
    • Identified the behavior to be that of a virus or DoS type attack
    • Applied a never admit policy to the created class “outbound/icmp/smalltic1”
application traffic management control

Visibility

Control

“Packeteer has allowed our staff to react very quickly to business requests and requirements.”

Gary Grieg, Network Manager, Global Operations & European Systems , Ace Insurance

Application Traffic Management: Control
  • Control utilization, fix performance & manage costs
    • Ensure the performance of key business applications – per app, session, or call
    • Contain impact of malicious, recreational & non-business traffic
    • Contain costs, maximize bandwidth & application investments

  • Policies/Partitions
    • Contain recreational traffic
    • Protect critical traffic
    • Smooth disruptive bandwidth intensive application traffic.
  • Strong Control
    • Set Per-Session Guarantees
    • Burstable configurations
    • Prioritized Access to Excess Bandwidth
    • Bi-directional control (inbound, too!!)

ControlShaping Improves Efficiency and Improves Latency
  • Manage congestion proactively
    • Throttling traffic at end stations
    • Coordinating at flow aware control point, managing when traffic is sent
  • Reduce retransmissions & latency
    • Queues and drops add network and/or application latency
    • Increases during congestion
  • Improve throughput
    • Reclaim bandwidth wasted on retransmissions

application traffic management acceleration

Visibility

Control

“We compressed the traffic from one application 25-30Mb down to 12Mb. The complaints stopped. We’re getting anywhere between 25 and 70 percent bandwidth savings, with an overall average of about 40 to 50 percent. It works better the more data you throw at it.”

Matt Matin, Systems Engineer, LandAmerica

Application Traffic Management: Acceleration
  • Further optimize performance
    • Increase WAN capacity via compression
    • Accelerate performance
    • Extend existing bandwidth expenditures

acceleration superior to compression only solutions
AccelerationSuperior to Compression-only Solutions
  • Compression alone does not solve application performance problems
    • Must assure created bandwidth is not consumed by recreational or other traffic
  • Bandwidth Management + Compression Optimizes Acceleration
    • Combination of proper allocation plus increased capacity improves transaction performance
