L2TP and TCP throughput
Hi Everyone, I'm hoping someone can guide me in resolving what seems to be a Buffer-bloat issue. I've been using tools such as 'https://devina.io/speed-test and have observed that TCP traffic through the L2TP tunnel, especially when loading websites, exhibits noticeable lag. Additionally, there have...

Re: ACCEL-PPP with FRR router
Hi @dimka88, Thank you once again for your guidance on configuring the gateway IP with ACCEL-PPP. Following your suggestion, I've set the gateway to one of the router's interfaces. However, this has made no difference. I am still observing a discrepancy in routing that I hope you can help me underst...

Re: ACCEL-PPP with FRR router
Hi @dimka88, thank you for your valuable insights. I've successfully configured the gateway IP address to be 10.0.0.1. However, I'm still encountering an issue where the gateway IP address appears in the traceroutes for outbound traffic. For incoming traffic, the routing table is respected, and the ...

Re: ACCEL-PPP with FRR router
Hello All, I've been delving into configuring my setup and examining the radius.c file on GitHub for Accel-PPP. It appears that when using the Framed_IP_Address for each user, it verifies through conf_gw_ip_address to ensure a gateway is defined. I attempted to employ the Framed-Route attribute spec...

Re: ACCEL-PPP with FRR router
Further to this, I've tried setting up a dummy interface.
ip link add name accel0 type dummy
ip addr add 10.0.0.1/24 dev accel0
ip link add name accel0 type dummy
ip addr add 10.0.0.1/24 dev accel0

ACCEL-PPP with FRR router
Hi Everyone, For a lab test, I decided to use ACCEL-PPP with L2TP directly on a router running FRR (BGP) I’m using Radius and Framed-IP-Address with FRR for L2TP and discovered I need to set the gw-ip-address interface address. Which is fine, if you are using ACCEL-PPP downstream of your BGP router ...

Re: Problem with Vlan-mon and Intel X710/X722
Have you updated the NVM for the X710? https://www.intel.com/content/www/us/en/download/18190/non-volatile-memory-nvm-update-utility-for-intel-ethernet-network-adapter-700-series.html If your X722 is onboard you will need to contact your motherboard manufacturer for the NVM update. I had a lot of cr...

Re: L2TP performance
Hi, Sorry for the delay in my reply. Please see TOP output as requested, in this case I am passing CPU's 0-7 to ACCEL. The CPU usage in all cases seems very low. I’ve been testing ACCEL using a wholesale 1 Gbps FTTP L2TP connection which terminated directly to ACCEL-PPP. I test using speedtest.net a...

Re: L2TP performance
Hi,
The CPU is a Xeon E5-2440 which runs at 2.40 GHz.
I disabled Hyperthreading, set the SG and disabled the suggested mitigations.
In all cases the overall CPU is very low.
What is the relation between the frequency and performance in this case?
Many thanks for your help.

L2TP performance
Hi all, I was just wondering if anyone is using ACCEL with L2TP and 1 Gbps connections. I have a test server running using a 40 Gbps - XL710-QDA1 NIC. The CPU usage is very low and I am using 8 cores. But the throughput is only around 300 Mbps. I've tried setting NIC optimisation, such as ethtool -K...
