Home Box Fiber + gigakraft gaming 300 - latency is too high

[MOCTuK]

Good afternoon!

 

I have installed Home Box Fiber (Docsis 3.1) router in my apartment (Vienna, Austria). I subscribed to gigakraft gaming 300.

I did a test and found that latency is too high.

With a free in a building WiFi I have a latency near 3ms and with Home Box Fiber + gaming tariff I have a latency 9ms.

Already next hop to my router introduces most of the latency. I guess that probably my router is connected not to Docsis 3.1

equipment in my building or a port is configured not properly.

 

Any ideas?

 

Thanks a lot in advance!

Hi, what does a traceroute to www.google.at look like? Have you ever made a speed test here: https://www.magenta.at/internet/speedtest? Please share a screenshot of the results here. Regards, RS.

Hi Roman,

Most of the latency is introduced on a first hop (which includes Docsis segment):

Speedtest is OK with down/up link speed.. But latency is measured as 8ms.

I guess my router is connected to Magenta's in a building equipment not capable of Docsis 3.1 or the

port is not properly configured.

 

Thank you for your reply!

Thanks for response. The speed and ping looks good to me. Magenta technicians can quickly find out if you are correctly connected to DOCSIS 3.1 by calling 0676 200 7777. Is the best way to call them. Br RS.

Hi Roman,

 

Thank you for your recommendation. I will try to reach Magenta‘s network engineers by a phone.

Ok. Please share here how and if you were able to receive assistance. Thx RS.

Hi Roman,

 

I finally reached English speaking customer service representative. He by my request contacted layer 2 support engineer.

Docsis 3.1 is confirmed for my link. Unfortunately it's Docsis 3.1 pure setup without a latency optimization. Because of that an average 10ms round trip latency is what can be achieved. To get a lower latency, Low Latency Docsis 3.1 (LLD)  should be implemented.

Hey, thank you for your information to this topic. I hope you can still utilize the internet for your purposes despite this latency. Best regards, RS.

did you manage to solve this problem with Magenta Support?

I would like to reduce my latency as well, on gigakraft gaming 300 with FritzBox 6660

latency to first HOP in network is 11-17ms

 

google search "Low Latency Docsis 3.1 (LLD)":

Low Latency DOCSIS is added to the DOCSIS 3.1 specification to handle this problem. It will keep the round trip time around 1 millisecond (for specific services), even under heavy load.
