Businesses rely on modern networks to carry critical information. When that information doesn’t get there, or gets there too slowly, it slows down the business. Techniques for analyzing latency sources have traditionally been difficult to implement, relying on round trip times or inline application analytics. Now, it’s just a few mouse clicks away.

Watch this WildPackets OnDemand webcast to see how the Omni Distributed Analysis Platform uses total network visibility to uncover real-world network performance issues. We show you a live demo of three common scenarios, using powerful tools to combine deep packet inspection with intuitive visualizations, to find the root cause quickly.

Here are the scenarios:

The server team and the network team are pointing fingers at each other. Users say the server is slow, but the stats show there’s not a lot of server load. We’ll show you in a single click how to get the answer. If it’s the network, we’ll show you where to find the slowdown.
The company is paying for a premium WAN link for a fast and reliable connection between sites, but VoIP and other time-sensitive traffic are having problems. The WAN provider says you need a faster link, but MRTG implies you’re not sending that much traffic across. Before you spend more money on the upgrade, take a few minutes to measure just how reliable the link is.
Wi-Fi is convenient, but a recent audit showed that the network password could be cracked in under an hour, so the company is rolling out 802.1X with WPA2-Enterprise, but people are having problems getting online, so they refuse to move to the new network. Since the Wi-Fi frames are encrypted, you don’t think you can use OmniPeek. However, the solution can be found by capturing on both wireless and wired.

  • 7. WAN SLA Validation and Link Latency Measurement#wp_omni7 © WildPackets, Inc.
  • 8. The Problem • “Business-class” WAN link ‒ Expensive, but it comes with a SLA • Results are disappointing ‒ The ISP says the link hasn’t gone down ‒ What about the rest of the SLA? • The ISP only performs latency and loss tests as troubleshooting • BERT/BLERT/loopback tests take the link offline • Can you measure the link performance yourself?#wp_omni7 © WildPackets, Inc. 8
  • 9. The Network Packets from end-user PC to remote server across WAN#wp_omni7 © WildPackets, Inc. 9
  • 10. Capturing on the Network Capture at each endpoint of the WAN link#wp_omni7 © WildPackets, Inc. 10
  • 11. Multi-Segment Analysis • Compare simultaneous data from end to end ‒ A single point only tells you flow health ‒ Multiple points measure link quality#wp_omni7 © WildPackets, Inc. 11
  • 12. Why Multi-Segment Analysis? • Old way: one capture at a time ‒ Gives direction, but not location ‒ Unplug system, move it, capture different data ‒ No guarantee of finding or reproducing the problem • New way: multiple simultaneous captures ‒ Track flows along the packet path ‒ “Bullet-time” visibility for data transactions ‒ Packet-level timing for link latency and reliability • The result: root-cause location ‒ Uncover patterns as flows are forwarded ‒ See where packet latency and loss are injected ‒ Measure quality of links without downtime#wp_omni7 © WildPackets, Inc. 12
  • 13. What We’ll See • Multi-Point Capture ‒ From wireless client to server room ‒ Client behind NAT • Link measurement ‒ Taken at ingress and egress • Multi-Segment Analysis ‒ Automatic processing of timestamps and routing hops ‒ Shows latency and packet loss#wp_omni7 © WildPackets, Inc. 13
  • 14. Demo#wp_omni7 © WildPackets, Inc. 14
  • 15. Application vs Network Latency#wp_omni7 © WildPackets, Inc.
  • 16. The Problem • Users are complaining of a slow server • Server team says stats look okay ‒ CPU & memory within tolerance ‒ It MUST be the network! • SNMP & Netflow look okay ‒ CPU, errors, dropped packets within tolerance ‒ It MUST be the server! • Where is the problem?#wp_omni7 © WildPackets, Inc. 16
  • 17. The Network Packets from end-user PC to local server#wp_omni7 © WildPackets, Inc. 17
  • 18. Capturing on the Network Capture in-line with TimeLine network recorder at 40Gbps#wp_omni7 © WildPackets, Inc. 18
  • 19. Latency Graph in Compass Dashboard • Comparative visualization of latency sources ‒ Allows quick latency troubleshooting ‒ Graphs wait times by application and network#wp_omni7 © WildPackets, Inc. 19
  • 20. What Compass Latency Solves • Is there a persistent problem? ‒ Are some segments or apps frequently slow? ‒ Are there occasional “hiccups” in the network? • Find what needs fixing ‒ Is it the application or the network? ‒ Figure out quickly where to spend time and money • Baseline information ‒ Are certain nodes slower than others? • Entire subnets due to old switches/routers • Certain servers, certain applications. ‒ Are some protocols slower than others? • E.g. HTTP vs SSL • SMB vs FTP#wp_omni7 © WildPackets, Inc. 20
  • 21. Why Latency in Compass? • Single-page visualization ‒ Easy to see “hidden” slowdowns ‒ View per-flow, per-protocol, per-node • Interactive information ‒ Quick drill-downs ‒ Find the information you want#wp_omni7 © WildPackets, Inc. 21

  • 24. End-User Experience Measurement#wp_omni7 © WildPackets, Inc.
  • 25. The Problem • Cloud-hosted service ‒ “It will save money if we don’t have to maintain it ourselves” • Road warriors are complaining about performance ‒ Troubleshooting on-site will eliminate the cost savings • How can you troubleshoot what you don’t host?#wp_omni7 © WildPackets, Inc. 25
  • 26. OmniPeek Remote Assistant • Small agent to capture directly on the end-user PC ‒ Simple user interface: “Start” and “Stop” ‒ Capture exactly what the PC sees#wp_omni7 © WildPackets, Inc. 26
  • 27. Why OmniPeek Remote Assistant? • Capture directly from end-user PC ‒ See what the PC sees ‒ No active connection required: diagnose connectivity issues • Test servers using end-user experience ‒ Client perspective measures how well service is delivering ‒ Capture from multiple different clients for global perspective ‒ Lightweight setup, no special equipment • Remote troubleshooting ‒ IT helpdesk or vendor tech support ‒ Strong encryption: data isn’t exposed, even at rest • Send the data, not an engineer!#wp_omni7 © WildPackets, Inc. 27
