Hello Everyone! What are the metrics that can be analysed or derived from Activity Network Diagram in relation to I.T project management ? I am still studying on how time management is being handled.
Someone who recently took the exam mentioned to me there was a network diagram question that essentially had a loop in it. He didn't mention the specifics, but was surprised as no exam preps really ever had it, and Rita's book had barely a mention of loops. I was led to beleive it wasn't just a "what are we seeing here" type question, but more of a calculate critical path or float type network diagram question.
Did you have something like this on the test? Does anyone happen to have examples of this with one or two practice questions?
Is everyone ding network diagrams for each of their clients? If so what are you using?
Sorry if this is a really beginner question but in all my time of working on my network at home (and at various family members houses) I've always just made little diagrams on the nearest bit of paper for planning, and I keep seeing these really nicely made network diagrams. So I was wondering what software you guys use to put those together?
Don't get me wrong the napkin network diagrams are functional (and cute) but they really aren't very professional if you get my meaning.

I was looking at the TP Link Archer C6 (Rs. 2400). I will be using 2 TP Link Omada Access points, so the range of the router does not matter. Will the processing power be enough to handle all these clients? (Or more) Or should I get a more expensive one like ASUS RT-AC59U V2(Rs. 5000)? Is the price difference (2x) justified in terms of specs?
Thank you for your help!
I learned about plantUML and nwdiag in particular in the not so distant past but never really used it. I like the idea of documenting things in code and just generate the images whenever they're needed; makes updating and revising things real easy.
What do you guys use at work?
Anyone have some suggestions for an easy to use network diagraming software? Something preferably free and easy to use. I don't want to spend too much time on learning the software. I just want to create a nice visual for myself.
For my network setup, I have a 1gig connection to a Google Wifi Router. These routers only have 1 LAN port so I connected that to a bridge. My PC is then also connected to the bridge. My VR space is in my basement with no ethernet jack so I have a MoCA device connected to my bridge, coax running to my basement, the 2nd MoCA device attached gets attached there and then that is plugged into my dedicated router with 5GHz only. My latency while playing Half Life through Virtual Desktop is around 40-50. Is there something else im missing here? I figured I would lose a few ms using the MoCA devices but I was still hoping to be in the 30s with this setup. Any suggestions?
UPDATE: I cut out the MoCA devices completely along with the "bridge" and moved the dedicated router upstairs by my PC so I can connect directly to it. My play area is 1 floor directly underneath the dedicated router and I don't notice any additional latency from what I was getting before. Seems to actually get slightly lower latency occasionally. Thanks for everyone's input.

Can anybody recommend a tool that I can use to create a network diagram from the command line.
Looking for some ideas of how best to generate some (internal) diagrams of various AWS architecture and just as importantly, make sure the diagram stays up to date. We use Terraform so was thinking about spitting out a new graph every time a change is made and then using graphviz or some other graph tool to pretty it up.
Curious what other folks are doing and if there are certain things that work or should be avoided.
Upgrading to a managed UniFi environment. Want to map out my network. Any good free alternatives out there for Visio anyone out there uses to create your diagrams?
UPDATE- Network Diagram v.2.0: https://imgur.com/a/7l81EK4

TL;DR: just have a look at the diagram and let me know what you think.
Hello, internet friends! (I feel like I've already "met" so many of you after digging through this sub for the past week... thanks for your helpful posts and comments!)
The first part of my research is done and it's now time to move ahead with most of the hardware purchase tomorrow if possible or Tuesday at the latest. That's where I need your help to check if I've got things right. I worked in IT for a few years, mostly just helpdesk, but never really got much into networking. I'm learning as I go and am grateful for your advice, experience, suggestions, corrections.
Within my budget of around $1500/1350€, here is a summary of my priorities in this upgrade:
- Performance: I currently have a 500 Mbit/s (really 300) and will probably soon move up to 1000 Mbit/s (really 800) for just a couple more bucks (euros...) a month. I want my setup to allow me to use all of it possible. Slight overkill is ok for a healthy bit of headroom.
- Stability/reliability: Not looking for the latest greatest, bells and whistles, but something rock solid. Not future proof, but reasonable for the next few years and covering the whole house well.
- Simplicity: Obviously this won't be plug-and-play or even fully single pane of glass, but I don't want something so complicated that I won't be able to explain the essentials to my average tech-savvy housemate.
- Security: Of course, I'll set up all the recommended security/privacy measures and probably a bit more via OPNsense and Pi-hole, but I don't live in fear of being hacked/spied on, etc. Anything that is "a bit more secure" but significantly affects the above priorities, I can do without.
- Fun/Awesomeness: do I really "need" this much in my home-network?
ProbablyCertainly not. Been surviving on much less up until now. But you're not here either cause you "need" to be... ;-)
Here are my main questions:
- Router/Firewall which box? There are 3 options in the diagram. Which one would you choose? They were the best price/performance I was able to find for my location. Here are the [cpubenchmark results](https://www.cpubenchmark.net/compare/Intel-i5-5200U-vs-Intel-i7-7500U-vs-Intel-i5-8265U-vs-Intel
I'm trying to draw up my home network on a diagram and it keeps turning out "meh".
I've got VLANs & virtualized services (sadly, no clouds YET) so there's definitely a fair amount of stuff involved. But I've seen larger diagrams that look much better on here--but of course now I can't find them :( So I'm asking the hive mind to link me to some pretty pretty network diagrams so I have references & design ideas for my own :)
I’m a new IT manager for a company and there has never been an IT role here before so there is no organization. The company has been around for 25+ years and I need to create myself a network diagram so I can show the CEO what we have / need .
My question is where do I start?? The router, server.. what do I need to add on there? I am using lucid charts for now. Thanks in advance!
Any feedback appreciated :)

Hi everyone, I am working on a network diagram to bring Wi-Fi to a remote office in the mountains. I am working on a budget, and would like to get this as close to right as possible right from the start.
Data usage: 1TB per month, for non-critical remote work, for about fifteen people.
Site notes: We plan to use a Starlink as the primary internet connection. There is no fiber or cable access nearby. LTE is only available 200m away on a hill near the upper building—that point has line of sight to a cell tower ten miles away. 25 Mbps over LTE is consistent.
Burying conduit will not be a possibility before early summer.
Distances: Hill <-200m-> Upper office building <-300m-> Lower office building
Hill: there is AC power here. I will have a Pepwave LTE router here, with an ATT 100GB /mo data-only SIM. Planning to use a Nanobeam to send data to the upper building.
Upper office building: Multi-WAN router connected to Starlink and Pepwave LTE connection, using Starlink as primary, failing over to LTE if Starlink goes down. One PoE nanobeam pointing up the hill, another pointing down toward the lower building.
Wifi: We have been using Eero Pros but I am open to suggestions.
Lower office building: PoE Nanobeam aimed at upper office. Nanobeam connection plugged into switch switch connected to a Wi-Fi setup similar to that of the upper building.
Here is the preliminary diagram: https://imgur.com/a/ApzAvvF
My main questions:
-
How can I choose the appropriate Ubiquity wireless bridges? Are they easy to set up and reliable? Do they come back online automatically ?
-
Besides Eero, what is a good Prosumer or inexpensive professional Wi-Fi solution? We can wire everything with ethernet cables.
-
Are there inexpensive Multi-WAN routers which can gracefully failover to the backup internet connection, then test the main connection every minute or so and switch back over when it is back up? I imagine this will mess up the public-facing IP of all of our users—however, I am not sure we need to aggregate the links, so maybe an occasional failover and jumbling of IP addresses isn't so horrible.
Any advice much appreciated! thank you.
I'm very inexperienced with this in general. I've played around with virtualization a little bit. Mostly just spinning up Linux VMs on a Win10 host. I don't have any real networking experience, other than setting up individual modems, routers, APs, and some port forwarding.
I don't expect to have this all up and running at once. I'm going to break it down into smaller pieces and get each one running one at a time. But I have some overall questions as I'm planning out my new house.
https://preview.redd.it/93qkuus4m7z71.jpg?width=1431&format=pjpg&auto=webp&s=bbc2a870a9f755ed9e39e58744837b1eb59621f7
- Does this make sense in general? Any generic comments or things that are completely off base?
- Is this a good VLAN plan? Probably more a question for r/HomeNetworking I'm trying to keep my IoT stuff separate from my personal devices. I don't know how I would get my HA/OpenHab server to talk with the devices, but as long as it's possible I can figure it out later.
- Again a question probably better asked in r/HomeNetworking. But, my house is almost 200 years old, so many of the walls are brick instead of wood. That makes running CAT5/6 through the house a major hurdle. As such, I'm planning to use wifi for just about everything. Because it's large, with three floors plus a basement, I was planning to use a mesh system from TP-Link. I know I can get everything connected to it, but how would I break out my IoT devices to a different VLAN? Would I need a separate set of mesh APs just for those?
- Should I keep the apps listed in the righthand side of my Proxmox server in containers, or separate VMs? Why?
- If the answer to the previous question is containers, would they be running in Docker? I've seen mention of "LXC" with Proxmox, but I don't know what that means or how it's different from Docker.
- If I'm using Docker for my containers, do I need to use Linux as the host OS?
- Can I setup "terminals" or something around the house to be able to leverage the power of my server? I'd like to get rid of my two personal laptops and just get something like Chromebooks or RPi's with a small monitor and keyboards to be able to remote into my Win10 VM to do general computing. MS Office, pay bills, etc. Ideally, my wife and I would both be able to log in at the same time, without disturbing each other. Would that mean separate Win10 VMs?
