Using Wireshark to Baseline HTTP-Ping

 Here’s something I like to occasionally do; run one of my tools against a packet capture to see how it behaves in the wire, does it have a signature in the packet, and if the features work as explained.


The point of the video is to practice packet capture techniques and analysis. I did not doubt that Wireshark and http-ping would have different response time values.


In this video, I compare the http-ping response times to what was on the wire.

Internet Woes

 I can bet you the majority of the people reading this has run into this issue.


As I’m working on the network design for this new site, I thought it would be a great idea to put the order in for internet for many reasons:

-          Sometimes there is a backlog and your next install date might be weeks away.

-          Even though we pull conduit to the sidewalk, it would be much easier, faster and cheaper to trench since its just dirt everywhere compared to when its finished and you have an asphalt driveway, landscaping, etc.

-          If the carrier doesn’t have your address in their database yet, there is time for them to get the backend stuff done.

 

I wont repeat what I said in the video, but the summary is simple; I called Carrier A since its their fibre and they tell me they cant service our address. So then I called 2 of their competitors who have no issue providing a quote for the install and monthly service..

 

Go figure...

Network Slicing

One of the most important features of 5G is Network Slicing.

Network slicing uses virtualization technologies, especially Software Defined Networks (SDN) and Network Functions Virtualization (NFV), which enable a 5G network operator to provide customized networks by creating multiple virtual and end-to-end networks, referred to as network slices. E..
