Ok so i am new to using protocol analayzer i ahve a couple questsions for those that are expertise in it..
On which layer will will i be using to find whether information is being retransmitted ?
Which layer will i look to determine whether there is a routing problem ??
reason i ask this, is because i am trying to troubleshoot my network problem... between my current work area and our headquaters in a different city.. The data being transmitted from each other is taking twice as long as it usually did a week ago ? i was told to use a protocol analyzer to help further find the problem... well i am new to using analyzer so if anyone could help me answer these questions, would be greatly appreciated thanks..
