6. Bandwidth UtilizationHow much is going to your mission critical Apps? Telecom/Data Circuit Budget Utilization Bandwidth Utilization • Are you getting an acceptable ROI for your network?

7. “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

8. 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.

15. 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 BeforeControl AfterControl

16. L L L L L L L L L ControlTraffic Shaping to Fix Performance Issues • 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!!)

19. 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

24. 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 Tolly Group, Understanding Traffic Management, 2003
