8. QoS
8.1 Frame Relay Traffic Shaping
You have been noticing drops on R5’s connection to the Frame Relay cloud. After further
investigation, you have discovered that R5 has been overwhelming R3 and R4’s connections to the
Frame Relay cloud. Configure Frame Relay Traffic Shaping on R5 in order to resolve this issue.
R5’s connection to the Frame Relay cloud supports a transmission rate of 1536Kbps.
R5 should send at an average rate of 128Kbps on DLCI 513 to R3.
R5 should send at an average rate of 512Kbps on DLCI 504 to R4.
In the case that the Frame Relay cloud notifies R5 of congestion it should reduce its sending
rate to no lower than 96Kbps for the DLCI to R3 and 384Kbps for the DLCI to R4.
In the case that R5 has accumulated credit it should be allowed to burst up to the maximum
transmission rate supported on the circuit to R4.
Bursting on the circuit to R3 should not be allowed.
Assume an interval (Tc) of 50ms.
3 Points
8.2 Rate Limiting
One of your NOC engineers has noticed suspiciously high utilization on the Ethernet segment of
R1. After further investigation you have found that a large number of ICMP packets have been
traversing this link.
In order to alleviate congestion configure R1 so that it does not send more than 128Kbps of ICMP
traffic out this interface.
Allow for a burst of 1/4th
of this rate.
3 Points
8.3 CBWFQ
Your company plans to reduce expenses by sending PSTN calls to the remote office connected to R5
across the WAN. Currently the WAN link is used primarily for data transfers and remote desktop
application.
Configure R5 to allocate 64Kbps of PVC bandwidth to VoIP bearer traffic, which is marked as DSCP
EF.
At the same time, guarantee 30% of remaining bandwidth to Citrix application traffic.
Set the queue depth for the Citrix traffic class to 16 packets.
All other remaining traffic should receive flow-based fair scheduling.
