Uctalk

[bilboSNB]

According to traffic stats 7 gigs worth of this protocol has been downloaded by a machine on my network over the past week.

What is it, does anyone else see this?

I’m unsure if this is your unknown data issue, but a quick google look up and I noticed this post on another forum:

Wanted to chime in here, and note that Google Chromecast devices employ this UcTalk tag during streaming.

Yes, I did see that however this is coming from a Windows 10 machine.

I'm also starting to see UcTalk app data usage in my Traffic Analyzer ? Having large upload data amounts... Does anyone have a clue what it is?

I there anyway I could block uctalk on the router to see who shouts?

Using FreshJR QOS V8.2 with RMerlin V384.9, and Trend Micro Signature V2.112 (2019/02/22 02:00) as my test, I just found out that the Speedtest from my ISP provider via their web interface was classifying this traffic as "UcTalk", which was going into my classification "VoIP and Instant Messaging". Since I do a lot of Speedtests via that Web Interface, I decided to take all "UcTalk" traffic (000017), and move that traffic into my "File Transferring" classification, which gets the least priority of all traffic, and it works great, so that I'm not interfering with other higher priority network traffic.

Thanks for this. I saw that I was uploading gigabytes of "UcTalk" but not downloading much. This comment leads me to believe it was from a friend streaming from my Plex server to her Chromecast, since the amount uploaded seems to match up with Plex's remote streaming bandwidth usage stats.
