Modern web design, what is it?

Question

Design

Advise where to look about the modern design of the network, how can you organize a provider network without vlan, and how do they build and what are the largest providers and companies guided by?
and another question about stp, does it really work so badly and is poorly compatible on different devices, or is it just that they say so about it? otherwise it’s too often I hear that they turn off stp, so somewhere there they said something that it’s better not to turn it on

Answer 1

Advise where to look about modern web design

No way, from the word "completely".

Answer 2

You decide which provider's network you want to build? Broadband, cellular, backbone, satellite, PM, OTT...
If we are talking about an Internet provider and VPN, then only pure MPLS, but no one does this, because it is expensive. And even then there will always be a vlan at the junctions with other operators. In other types of operators, you can do without vlans at all, but why give up the technology that is understandable to all signalmen and crutches?

Answer 3

> network without vlan
impossibru.
There is an alternative to bare L2. vpls is expensive, vxlan is even more expensive. TRILL/SPB/Fabric - data center magic, which is still so young that presale engineers themselves have not seen implementations in live solutions.
And on PE, vlan tags will still be used to separate / identify services.
> stp
It works, there are few glitches (although even in the software of first-tier vendors there are serious jambs), it does its job.
But you really should turn it on only where you can’t do without it (where an automated l2-channel reserve is desperately needed), because in addition to pluses, it has a lot of minuses and you need to prepare it very carefully, so that even before the algorithm works out, the admin knew that where it would lock up, where it would unlock when it fell, and where poppy tables would be cleared ..

Answer 4

Look at the websites of network vendors - they should have a bunch of Design Guide.
For example, Cisco
