Three kinds of service data traffic enters into inbound port through IP source address. The traffic of 22.214.171.124 is 60M; the traffic of 126.96.36.199 is 20M and the traffic of 188.8.131.52 is 20M. Tag NE20 100M inbound port and divide them into high and low priority. The priority of 184.108.40.206 is high, others are low. Configure car at outbound port and the speed-limit is 70M. QoS is applied. It is predicted that the traffic of 220.127.116.11 all passes and there is no loss. For other two ones, there is loss and it is about 15M. And then there is loss for them and their loss rate is similar. The whole traffic is about 70M and gts phrase is not in effect.
Delete car phrase and reserve gts phrase. The traffic of 18.104.22.168 is added to 70M. The traffic of other two ones is added to 30M. 60M traffic bandwidth with the priority as ef is guaranteed. There is great loss for other two ones.
QoS is realized.
During the realization of NE20 QoS, if there is car and gts configuration. The system first chooses car parameter. If there is conflict between gts phrase and car phrase, car phrase is first chosen. For this case, bandwidth 70M speed-limit is first realized and gts of QoS is not in effect.
For NE20 configuration, if there is gts demands of Qos, avoid configure car phrase.
