Business Ethernet As The Prefered Choice For Business Voice/Data Networks

Given that business ethernet is the likely prefered choice by businesses today ... what makes it so attractive?

Ethernet is preferred because all customers have devices that already have Ethernet ports, everyone sort of knows what the cables look like (I have seen 4 line phone cables used - so maybe not quite simple enough for a lobotomized chimp, but still close). The interfaces already exist in, and lowers the cost of, switches, routers, firewalls and servers.

Also as the Telco’s bring Ethernet to the demark, it allows the customer to place less expensive and more basic equipment against the telecom provider (the WAN port), and it also allows the Telco to press a less expensive network management product deeper into the customer network – it’s a win/win for both the customer and the telecom vendor.

Most of the terms (business ethernet, metro ethernet, carrier ethernet, ethernet over copper, fast ethernet, and ethernet-MPLS) are marketing terms, those terms don’t exist in the technology. MPLS is MPLS, terms about how a packet enters the network is just some marketing person putting terms together so the salespeople can understand and explain the product. Marketing terms may “sort of” mean something, but a vendor can assign any meaning they want to them.

It’s like adding routing to a switch, and then calling it a Layer 3 switch. Layer 3 is routing, the definition of routing is an interface decision made at Layer 3 – marketing makes it a L3 switch, not technology.

The exception is “Fast Ethernet”. Ethernet started out at 10 Mbs – “Fast Ethernet” refers to all the 100Base-T products (100 Mb/s). Ethernet is a Packet type, not a port type, it can run over copper, fiber or wireless. There is also Gb Ethernet (1000BaseT), 10 Gb, 40 Gb, and 100 Gb. 40 and 100 are sort of inverse multiplexing of Ethernet – but that’s a different story.

The need for reliable data access that can accomodate remote workers and multiple locations makes the right connectivity a critical decision. No matter what term you use....or flavor you ethernet rises to the challenge.
