I have a question for the QOS gurus out there. We are having some problems with packet loss for our smaller MPLS locations. This packet loss is due to the large speed differential on our Hub site(150mb/s) in comparison the the branch office locations(single T-1 to 4.5mb/s multilinks). This packet loss only seems to impact really bursty applications like our Web Proxy. I have been around and around with WindStream to give me some extra buffer or enable random early detection on the smaller interfaces in my MPLS network. So far they are unwilling to do a custom policy and none of their standard policies have enough buffer to handle the bursts. They do FIFO tail drop in every queue, so I can’t even choose a policy that has WRED implemented. I am looking for a way to solve the problem on my side. I can create a shaper for the proxy and match off an access-list to the smaller sites, but I am either forced to do bandwidth reservations for each site, or have multiple sites share the same shaper. Here is an example of what I was playing around with: ip access-list extended ProxyT1Sites permit tcp any host 10.x.x.x 10.x.x.x 0.0.0.255 permit tcp any host 10.x.x.x 10.x.x.x 0.0.0.255 class-map match-any ProxyShaperT1 match access-group name ProxyT1Sites policy-map WindStream class VOICE priority percent 25 set dscp ef class AF41 bandwidth percent 40 set dscp af41 queue-limit 1024 packets class ProxyShaperT1 shape average 1536 bandwidth percent 1 set dscp af21 queue-limit 1024 packets class class-default fair-queue set dscp af21 queue-limit 1024 packets Another Idea I had was to create a bunch of shaper classes all feeding the same child policy for priority queuing and bandwidth reservations based on DSCP markings. I’m just not exactly sure that this is allowed or supported. I also would run out of bandwidth allocation on the policy if I use the true bandwidth number of 150mb/s. It is on a Gig port so I could just take the bandwidth statement off of the interface to give myself enough room for all of the shaper allocations. Something like this(I am omitting the access-list that matches the branch subnet and class map for brevity): policy-map PerSiteShaper class FtSmith shape average 1536 bandwidth 1536 service policy Scheduler class Dallas shape average 4500 bandwidth 4500 service policy Scheduler class NYC shape average 100000 bandwidth 100000 service policy Scheduler class-default service-policy Scheduler policy-map Scheduler class VOICE priority percent 25 set dscp ef class AF41 bandwidth percent 40 set dscp af41 queue-limit 1024 packets class class-default fair-queue set dscp af21 queue-limit 1024 packets Just looking for some ideas that do not involve building tunnels to our remote offices.
