Attention CNET: The 90's called and they want their article back.

The dawn of the flat network?
Posted by Jon Oltsik

For the longest time, networks were built in three tiers: access, aggregation, and core.

Are you kidding me? Maybe in the Cisco lab, but in the real world flat networks have been around for decades.

This made a lot of sense back in the old days because of network technology limitations and traffic patterns.

Made sense to Cisco maybe, but no one else.

But alas, network usage and technology have radically changed since then. Network packets carry all sorts of traffic consisting of chatty protocols, voice, and multimedia.

Yeah, because IPX/SPX wasn’t chatty at all was it?

As for networking technology, many historical limitations are fading away. Today’s networking devices have superior capabilities in four key areas:

1. Wireless support
The new 802.11n IEEE standard is a game changer that may eliminate the need for most wired connections.

I don’t think 802.11 bringing back the shared hub is quite the fading away of historical limitations.

2. Port density
A 24-port access switch can join others in a stackable or virtual configuration. The result? Tons of ports for connectivity.

Shit, can this be real? What were those 24 port stackable VLAN switches I was installing 14 years ago?

3. Performance
Networking equipment combines 10-gigabit Ethernet with incredibly fast system backplanes.

Been there, done that in the 90’s no less.

4. Intelligence
Devices can easily combine Layer 2 switching, Layer 3 routing, and a host of other packet processing capabilities.

WTF? Are layer 3 switches new 21st century tech?

Over time, these device-centric changes could alter the way we build networks and greatly impact the networking industry. Packet processing and forwarding decisions will be made throughout the network, not at specific aggregation points alone. As this happens, the network could morph into an intelligent flat fabric rather than today’s hierarchical structure.

No, this won’t happen overnight, but the roots are already being planted. Hewlett-Packard has been talking this game for a while and is rapidly becoming a major networking player. Juniper Networks’ entrance into the Ethernet switching market will also accelerate the model. As for Cisco Systems, it has the most to lose but is adjusting its game accordingly. John Chambers & Co. may not want a flat network, but they understand that technology advances are pushing the network in this direction.

Did CNet mistakenly dredge up an article from the 90’s and time stamp it today?

What a piss poor article. CNet should be ashamed.
