3. Agenda
• Network capture overview
• Real world use cases
‒ WAN SLA validation and link latency measurement
‒ Application vs. network latency
‒ Remote end-user experience measurement
‒ Uncovering wireless issues
• About WildPackets
#wp_omni7 © WildPackets, Inc. 3
7. WAN SLA Validation
and Link Latency Measurement
#wp_omni7 © WildPackets, Inc. www.wildpackets.com
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
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
22. What We’ll See
• Capture from TimeLine
• Latency graph in Compass
• Proof in the packets
#wp_omni7 © WildPackets, Inc. 22
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
28. What We’ll See
• Capture file from OmniPeek Remote Assistant
• Transparent decryption
• Latency source diagnosis of SSL traffic
‒ It’s not always the network…
#wp_omni7 © WildPackets, Inc. 28
31. The Problem
• Users can’t connect to wireless network
‒ Association without IP
‒ Authentication problems
• Wireless network is “slow”
‒ Users complaining about “pauses”
‒ Logs show disconnects, reconnects
• Ever wish you could swap out the cable on wireless?
#wp_omni7 © WildPackets, Inc. 31
