I am trying to determine if my current bandwidth is meeting my needs. I have 512K symmetric at a location, but they are reporting slowness. I looked at the bit rate graphs from within the PDM, and looked at the input/output bitrates on both the inside and outside interfaces. My question is this - which graph represents my "upload" and which is my "download". The reason I ask is because I am considering moving to cable modem which is 1.5 down/256 up, and I need to know if I am exceeding my upload.
