| Huge latency increase caused by saturating 1 port synced @ 100mbit on unmanaged 6-port gig switch. Posted: 01 Feb 2020 03:16 PM PST I ran into this weird issue in my home last night and was curious what exactly the cause is. I have gigabit FTH in my condo, running pfsense on a white box mini pc with only 2 Ethernet ports one wan one lan. The pfsense lan port connects to a 6 port unmanaged dlink switch which connects to the punch down block for all the Ethernet ports in the condo. Guess they did a pretty poor job with the runs because some of rooms will only sync up @ 100mbit and other will run at gigabit. Anyways I noticed that if I saturate a port synced at 100mbit my wan latency increases by 50-200 ms and really bad jitter. I can nearly saturate my gig connection on another port synced at gigabit speeds and it barely effects latency or jitter of my wan connection. Would this be caused by the switch having a hard time buffering packet queues between different interfaces synced at different speeds? Can this be fixed by getting a better switch?

| What programming language for networking? Posted: 01 Feb 2020 03:23 PM PST I have been learning networking with python because it is fun if you do the right projects ;). if I would look for a career in networking what language or languages would be necessary? [link] [comments]  |
| How to start a networking side gig job? Posted: 01 Feb 2020 04:54 AM PST I currently work as a network admin, but I want to make some small cash on the side. Currently, a colleague contacted me about some company that needed a guy for a one-time project to get all the networking gear up and running. With basic configuration, nothing complex, but they wanted to just pay and be done with it. I accepted this, said my price per hour and we scheduled this for the next weekend. So I thought why not make this more common and make extra money on the side, but I need some info on how to start all this up. How to get to people and offer my services. I want to provide maybe low-level "consultancy" to non-IT companies for basic internet/wifi setup, configure cisco routers and switches, or anything in that matter. But still, nothing extremely complex that will take a huge chunk out of my free time. Maybe will step it up in the future, but for now, that will be it. My main job is flexible around taking days off, arriving late, or leaving early, no hassle there if I need extra time in order to go for this. Can someone who started like this or is doing this currently can share some info on how to get going?
Thanks! [link] [comments]  |

| Posted: 31 Jan 2020 10:56 PM PST they are lots of information regarding loss in connection of fc/apc and fc/pc type of single fiber connectors.. but is there extra loss in fc/upc and fc/pc connectors? are upc and pc type connector are compatible? [link] [comments]  |
