WAN SLA Validation

and Link Latency Measurement


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?

8


The Network

9

Packets from end-user PC to remote server across WAN


Capturing on the Network

10

Capture at each endpoint of the WAN link


Multi-Segment Analysis

• Compare simultaneous data from end to end ‒ A single point only tells you flow health

‒ Multiple points measure link quality

11


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


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

13

Application vs Network Latency


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?

16


The Network

17

Packets from end-user PC to local server



18

Capture in-line with TimeLine network recorder at 40Gbps


Latency Graph in Compass Dashboard

• Comparative visualization of latency sources ‒ Allows quick latency troubleshooting

‒ Graphs wait times by application and network

19


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


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


What We’ll See

• Capture from TimeLine

• Latency graph in Compass

• Proof in the packets

22


Demo

23


End-User Experience Measurement


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


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


What We’ll See

• Capture file from OmniPeek Remote Assistant

• Transparent decryption

• Latency source diagnosis of SSL traffic ‒ It’s not always the network…

28


Demo

29


Troubleshooting Wireless


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?

31

‒ Signal strength visualization

• Decrypt WEP, WPA, WPA2-PSK ‒ Full packet data visibility

‒ MSA provides wired/wireless comparisons

34


Why OmniPeek for Wireless?

• On-site analysis ‒ Walk the floor with OmniPeek

‒ Aggregated capture gives cross-spectrum visibility

‒ Track down weak signal locations

• Remote analysis ‒ Remote adapter turns AP into capture source

‒ Capture with USB over IP hubs

• End-user analysis ‒ OmniPeek Remote Assistant with WildPackets driver

‒ Promiscuous wireless capture shows 802.11 admin packets

35


What We’ll See

• Roaming
