Is this a set maximum or a practical max if |you are running lots of services? Can I run 8 DSPs on one Arc if I'm just |doing basic dial-up with no tunneling and such? | The 7DSP number came about from stress testing of HiperARC 4.0.x code. from that testing a performance fall off was seen after adding the 8th span of calls. (these calls are all doing PPP and FTP downloads. ). Since then the falloff has moved out and the severity of the fall off greatly reduced to a point of little impact for a full 14 spans. The FTP test is a little more severe than the stand mix of activities/data rates/packet sizes seen in normal operation. The 7 span recommendation is still in effect if IPX or l2tp is to be run over the PPP links. So the answer to your question is 8 DSPs will not be a problem. You should be running 4.1.59-6 or newer code on your HARC and DSP 2.0.81 or newer. -M - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
