    t1 inbound congestion latency

    Don't get me wrong jneil, I appreciate and value your posts & feedback. Sorry to make you aggrivated or whatever. I am discovering things as I work with this and am posting what I have discovered, I don't mean to sound like I'm disregarding what you guys are saying. Hopefuly this will...

    t1 inbound congestion latency

    Thanks again for the replies. From my understanding of load-balanceing and CEF this will still not give me the low latency queueing that I am aiming for. What I am after is not allowing the high-bandwidth flows to congest the queue buffer. Hence my instance on the queueing method being the...

    t1 inbound congestion latency

    Thanks for the replies.. Yes as I stated there were 'dribbleing errors' found on the cicruit during testing. This was fixed late last week (1 bad pair, and replaced telco interface card). I recently did a 'clear count' and I'm not taking any errors now. I knew after posting that sho int it...

    t1 inbound congestion latency

    Thanks for the reply, Here is the sho int s0 (below) As described above I already have flow-based WFQ enabled on the s0 interface. Outbound traffic behaves nicely with it enabled. It is the inbound traffic I am having congestion latency problems with. I am trying to have my ISP enable WFQ on...

    t1 inbound congestion latency

    Thanks for another reply jn.. It seems to me that on their end they are using fifo because of the latency seen during inbound congestion. What I was wondering is if I should request that fair queuing be enabled on their end and if its common to do so. I respect your opinion that we may need...

    t1 inbound congestion latency

    Thanks for the reply.. The other side of the link is my ISP. I know they offer class-off-service options for a cost, but it seems that is really not what I want or need. I simply want to have some sort of congestion avoidance on the inbound regardless of traffic type as I am doing with traffic...

    t1 inbound congestion latency

    Hello all, I am working with a cisco 1720 router and t1 service. I noticed congestion latency on both inbound and outbound traffic of ~350ms under heavy load. I enabled 'fair-queue' on the t1 serial interface (t1-wic) and the *outbound* congestion latency went way down to ~5ms. However any...
