I am curious if I have a correct understanding of the two. I am new to CBAC.PIX does the following:1. Uses access-lists to allow outgoing and incoming traffic at layer 3 and layer 4 (port redirection).CBAC does the following:1. Augments access-lis...
I have a Frame relay network with 14 remote sites (PVCs). The frame is a full T1 link. 12 sites have a 16 Kb CIR, 1 with 64 Kb and 1 with a 128 Kb CIR. They are all burstable anywhere from 64Kb to 256 Kb. The hub router for the frame network is a...
Well I have two other frame connections that I administer and they run fine without any BECN or FECN packets. If they have to retransmit, then that would cause delay. It would be better to throttle back the transmission around the CIR and go at a s...
So just to be completely clear, let me summarize. "IN BECN" packets from all the pvcs into my hub router means that there is congestion in the frame cloud going from my hub router to all the remote sites. "IN DE" packets into my hub router means tha...
For DE, check out Mick Phelps reply to this conversation. As an example for fecn and becn, all my pvcs on my hub router have "in becn" and "in de" packets. That means that the frame provider is sending these notifications to tell me that there is c...
So, if I receive several fecn and becn packets, does that mean that my provider has something wrong with their circuits? Or, does it mean that because my traffic is consistently above my CIR, that my service provider will allow my traffic to experie...
