Network visibility

As long as we’re being pedantic, January 1, 1983 is considered the official birthday of the Internet, when TCP/IP first let different kinds of computers on different networks talk to each other.

It’s 2021, hence the Internet is less than, not more than, 40 years old.  Given your mathematical skills, I put no stock in your claim that we still can’t “buy an NMS that just works.” :)

Hi there,

I'm interested in what you good folks do in terms of network visibility.

My interests are around Service Provider space - visibility for IPoE, PPPoE, TCP(User Experience).

I use a product called "VoIPmonitor" for all things VoIP - and it is one of my favourite tools.  It is a web gui for sip/rtp/etc.

Is there a similar tool in the Ethernet(L2)/IP(L3) space?

Are operators using tcpdump/wireshark for this - or is there a voipmonitor-esque tool out there?

It's 2021, and more than 40 years of the Internet, we still can't walk into a shop and buy an NMS that just works :-).

Oddly, I was searching for a good system to manage subscriber management on our end (Broadband), and we eventually landed on Splynx.

So not sure if you want to see things on the wire (Layer 1 - 4), or if you are interested in pretty pictures...

At any rate, you may very well need more than one system to monitor your entire network.
