3. What Is The StarNet Analyzer? What does the StarNet Analyzer do? How do I get an SNA test? How do I get passing SNA test results? How do I read the SNA test results? What do I do if I get a failed test result? What bandwidth options are available?

4. What Is The StarNet Analyzer? The SNA test monitors an Internet connection for packet loss, latency, consistency, and speed. The test is a Java applet that requires Java Version 1.6 or higher. Once the SNA client is started it will report an observation back to the server every 5 minutes. A complete test takes 48 hours and involves a total of 578 observations.

5. 5 How Do I Request An SNA Test?

6. How Do I Get An SNA Test? Login to the Star2Star portal, and click on the Dealtrack link. Scroll down to the bottom and select the client and location you would like to run an SNA test for. Once the General Tab is displayed, click on the StarNet Analyzer tab. Fill out the appropriate fields and submit the test. Make sure you see a purple and green box and a ticket number. Add a comment for duplicate tests. We will send you an email with your test within 24 hours.

10. 10 How Do I Run The SNA Test To Get Passing Results?

11. Recommended Settings Use a dedicated computer, preferably owned by you. Install remote access software such as LogMeIn.com, VNC, or Teamviewer. Turn off all software firewalls. Disable Windows update. Disable all power settings. Disable anti-virus software as it has skewed test results. Run test outside of firewall or router. Run test during business hours.

12. Remote Control Remote Control Software o http://realvnc.com http://realvnc.com o http://logmein.com http://logmein.com o http://teamviewer.com http://teamviewer.com

13. Recommend Testing Case Running test in parallel with client network.

14. DMZ Port SNA Test Setup DMZ port on client firewall

15. Devices With Known Issues Linksys home grade routers and switches Sonicwall – must use DMZ

16. Testing Ports SNA Testing Ports Speed test: 80 TCP and UDP (HTTP) VoIP Simulation: 5060 TCP and UDP (SIP) 19999 TCP and UDP (Media Upstream) 20000 TCP and UDP (Media Downstream)

17. 17 How To Monitor And View Running SNA Tests

18. How To View Running SNA Tests Use Firefox, Chrome, or Safari web browser Login to the portal and go to the Dealtrack tab to view running SNA tests. Click on any client in the edit section. Click on the SNA tab once the general tab is displayed. Scroll to the bottom of the SNA tab, and click the View All Active StarNet Analyzer Tests link.

19. 19 How To Understand SNA Test Graphs

20. Jitter Example of a failing jitter graph Be sure to read the Y axis scale when viewing graphs

21. Jitter Example of an excellent jitter graph

22. Packet Loss Example of a failing packet loss graph

23. Packet Loss Example of a passing packet loss graph Notice the scale of the highlighted axis

24. Reading The Graph Excellent Jitter Results Excellent Packet Loss

25. Passing Test Scale Jitter: At or below 15ms average and few spikes of less than 50ms Packet Loss: Under 1.5% with a couple of spikes no greater than 3% Speed needs to support # of lines x 40 kbits, plus overhead for data usage Round Trip Time: At or below 60ms with a couple of spikes

26. Common Test Problems Request does not generate ticket number with purple and green box, likely due to duplicate test request, add something to comment field. Running test behind firewalls returns poor results. Running test on computer with heavy usage. Running test on computer with software firewall and/or other blocking features Test stopped early due to computer issue, total observations should be 578

27. Common Test Problems Windows update downloaded updates while test was running Windows 7 computer user must be logged in as Administrator or use the “Run As…” command

28. 28 What Do I Do After A Circuit Failed The SNA Test?

29. Fixing Failed Circuits DSL and Cable: Try replacing the on-site modem Wiring can always be an issue, especially old wires Signal levels on DSL and Cable can cause problems Overuse of bandwidth can cause issues. Ask the ISP for a data utilization report Open a trouble ticket with ISP sighting issues as seen on test results, for example high packet loss % Review perimeter network topology Consider a different/dedicated ISP Last resort: waive 30-day money-back guarantee

30. 30 Bandwidth Options

31. DSL – Good solution for SMB, voice, and data Cable – Works well, a lot of bandwidth T1 – Small amount of bandwidth but stable FIOS – Excellent, lots of quality bandwidth Metro-E – Very good for public Internet access Fiber – Fast and a lot of bandwidth MPLS – Good bandwidth, but must of DIA (Direct Internet Access) option for public IP address Wireless – Not reliable, issues with packet loss

32. Common Circuit Issues T1 is not very much bandwidth in regards to current data usage. This is a common bottleneck. Wireless circuits tend to be unreliable and can have issues with packet loss at random times. It it common for an MPLS to be a private point to point connection. Client uses video conferencing or is a heavy video user which uses up a lot of bandwidth.
