Baselining Session – Network Throughput

 Here is another slide from our baselining series.  This one is going to focus on network throughput testing.  I use a couple laptops, and iperf3 software which you can get for free at https://iperf.fr/iperf-download.php

The key message is to develop a consistent methodology to test your equipment and network.  I emphasize to create a sample size; mine happens to be five to start with.  Obviously, the more samples you have the more accurate the values will be.

Even though I use iperf3 in this session, there are many other products that will do the same thing. I just wanted to get those who have never done this, started with something. 

Have fun folks.

Wi-Fi specification details

 When troubleshooting, getting the specifications or WiFi details from the vendor can be daunting. if you go down the internet search rabbit hole, you typically have no idea how, or where, the information was gathered from. my rule of thumb is if i read something on the web and there is no reference links, i take it with a grain of sand.

You should take the time to go through the vendors website or ask your reseller for the WiFi specs and file it away BEFORE you have an problem.

For example, i dug up these 2 WiFi specification web pages from the apple support site that you might find helpful.

What is Gateway Load-Balancing protocol (GLBP) andhow to implement the configuration?

 

GLBP Gateway load-balancing protocol is providing redundancy gateway and true load

balancing. GLBP allow a mechanism of four routers in each forwarding group. By default, the

active router directs the traffic from host to each successive router in the group using Round-

Robin algorithm.

Who wants to take this bad boy for a spin

 

This Radio Shack Model II computer had the Z80A processor running at 4MHz. It came with a whopping 32KB of Ram and a single sided 500k eight-inch floppy disc (single sided double density).

It was a tad over $6k. Of course, you had to get the daisy wheel printer (add in another $3k). It came with TRSDOS but had to purchase Scripsit (word processor) at $300 and Profile (database) $300 and then finding out that this was a CP/M based system and was able to use VisiCalc.

You could always expand this system with their additional 3 eight-inch drive expansion unit for around $3k. or you could have upgraded to either a Model 12 with DSDD (double sided double density) drives or the Model 16 running a whopping 6 MHz and a Motorola 68000 processor for around $5k. Later in 1983 came the Model 16B with 256 KB running Unix.
