WAN SLA Validation
and Link Latency Measurement
© WildPackets, Inc. #wp_omni7
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?

Multi-Segment Analysis
• Compare simultaneous data from end to end ‒ A single point only tells you flow health
‒ Multiple points measure link quality
11
© WildPackets, Inc. #wp_omni7
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
12
© WildPackets, Inc. #wp_omni7
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

Application vs Network Latency
© WildPackets, Inc. #wp_omni7
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?

Latency Graph in Compass Dashboard
• Comparative visualization of latency sources ‒ Allows quick latency troubleshooting
‒ Graphs wait times by application and network
19
© WildPackets, Inc. #wp_omni7
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
20
© WildPackets, Inc. #wp_omni7
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
21
© WildPackets, Inc. #wp_omni7
What We’ll See
• Capture from TimeLine
• Latency graph in Compass
• Proof in the packets

End-User Experience Measurement
© WildPackets, Inc. #wp_omni7
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?
25

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
26
© WildPackets, Inc. #wp_omni7
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!
27
© WildPackets, Inc. #wp_omni7
What We’ll See
• Capture file from OmniPeek Remote Assistant
• Transparent decryption
• Latency source diagnosis of SSL traffic ‒ It’s not always the network…

Troubleshooting Wireless
© WildPackets, Inc. #wp_omni7
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?
