Hi all,
we run into some trouble with our PPPoE Access Concentrator (CCR1072 with ROSv6.46.4 stable). We have >~1k sessions. and around 2Gbit/s peak traffic. The bandwith of our DSL customers is shaped at the DSLAMs (in the most cases, not all) but our FTTH and radio customers are shaped by Queue on the CCR1072. At the moment that are ~300 Queues. Most Queues are dynamic via PPPoE but some are static simple queues with standard settings (besides Upload/Download Limit).
Here is the problem: When a customer with FTTH 500Mbit/s uses his bandwith, the CPU load increases to nearly 100% with all resulting consequences!
Please, take a look on the pix:
Queues on the Access Concentrator, sorted by Max Limit.
Last 12h statistics. You can see the massive CPU load + very high latency in the hole network
Last 7 days statistics. You can see that there is no problem with traffic/performance aslong as the "big" queues aren't fully used.
Does anyone have an idea how to manage that problem? The customers are connected to the network with CRS317/CRS328-4C-20S-4S+. We used to shape costomers by "Switch -> Port -> Ingress/Egress Rate" but our customers complained about packet loss. So we changed to "open" Ports and Queues...
If you need more Infos pleas ask! Thanks in advance.
