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.

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

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.

Remote Control

• Remote Control Software

Recommend Testing Case

•Running test in parallel with client

network.

DMZ Port SNA Test

•Setup DMZ port on client firewall

Devices With Known Issues

• Linksys home grade routers and switches

• Sonicwall – must use DMZ

Jitter Results

Excellent

Packet Loss

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

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

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

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

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

Bandwidth Options

Bandwidth Options

• 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

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.
