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.

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

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?
28
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
30
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.
