DIAGNOSING CONNECTIVITY PROBLEMS
If you are experiencing continual Internet Service
Provider (ISP) connection problems and/or MySpeed is
reporting measurements below what you are expecting
from your ISP, you can initiate a VisualRoute trace
to analyze the connection being tested by MySpeed.
A VisualRoute trace helps you identify the cause of
the connection problem by testing and measuring the
quality and performance of every ISP server between
you and the destination MySpeed service.
From MySpeed
PC, you can start a VisualRoute
connection analysis by clicking the Trace icon
in the top right, or the run a VisualRoute
network trace link in
the analysis section. If you do not have VisualRoute
installed you may download a
15-day trial.
VisualRoute reports 4 vital
pieces of information:
Packet Loss -
loss of data packets normally indicates heavy network
congestion and causes poor connection performance.
Packet loss is shown in the % Loss column in the
routing table. In the VisualRoute Report below,
data packets are being lost at hop 15. By looking
over to the Location and Network column for that
hop, we can see that the network device is located
in New York and pertains to the NTT America service provider.
Latency -
the response time for a data packet to travel to
the server and back. VisualRoute indicates network
hop performance by marking them Red, Yellow or Green
in the routing table. Network hops that appear in
Red have a higher than expected response time.
In addition, the average response
times are shown in the ms column. The graph
column provides a visual respresentation of the network
latency, the horizontal grey bars indicate the response
times to ping packets, the vertical blue lines indicate
the average latency for each hop (the numbers shown
in the ms column). A high value
in the ms column
or wide grey bar in the graph column indicate poor
connection performance for that network hop.
Location -
the geographical route of your connection can indicate
if an ISP is sending your traffic by a long winded
route causing unexpected delays. A direct network
route normally provides a faster response time, and
thus better connection performance, than a non-direct
route.
Number and ownerships
of servers, or 'hops', between you and
the destination identifies inefficient routing
by ISPs (which may not be your ISP but another
ISP between you and the destination MySpeed Server
you are using). In general, the higher the number
of hops, the longer it takes for data to reach
the destination.
If packet loss or latency is occuring in your
Internet connection it should be reported to the
network provider responsible for the network hop
where the problem occurs. To do so, click on the
name in the Network column
for the problem hop to see the Whois information,
and look for the Technical or Admin contact information.
You can easily send a copy of a VisualRoute Report
by email by using the Edit,
Snap as Text or Edit,
Table/Map as JPEG menu options in VisualRoute,
then pasting or attaching the information to your
email message.
