Ethernet Concerns For Businesses Today

There appears to be a lot of hype promoting Ethernet everywhere for Internet and private networks. However, reality can be quite different. There are a limited number Ethernet-enable lit buildings in the US or globally.

If your office, is in a lit building, colo or carrier hotel, great! You may be able to get 100 Mbps FastE, GigE or even 10GigE ports. Many potential ethernet customers are not in lit buildings, but are close enough to get 10 Mbps Ethernet over Copper (EoC) or DS1 (EoDS1) or up to 100 Mbps Ethernet over multiple DS3 lines. Locations further away from Ethernet POPs may be limited to more traditional options such as DSL, T1, NxT1 or DS3 bandwidth.

The largest wireless carriers are all but demanding carrier Ethernet of their wire-line counterparts as part of a growing dilemma around delivering large date/media content to the handset. Over the past couple of years, wireless providers discovered that the data bottleneck was no longer the handset, but the delivery system to the cell site locations. Traditional T-1 architecture is becoming a costly pill that wireless providers don't want to swallow. The alternative is Radio Access Network aggregation to Pseudo Wire (PWE) technology for the current RAN systems and eventually native packet delivery over later versions of RAN architecture. All of which would be carried on Business Ethernet.

So here are the topics of concern -

1) Will executive management of wire-line companies see past T-1 delivery for the wireless carriers as a whole? Does it make financial sense for them or will they continue to force traditional TDM architecture.

2) Will bonded copper applications have a place in carrier Ethernet delivery, or must we expect fiber to be the only transport medium?

3) Will PWE3 standards be proven as a reliable T-1 emulation and delivery system?

4) Will carrier grade Metro-E find a place in the LEC portfolio? Will latency and jitter issues prevent wireless carriers from moving to this transport medium in an effort to smooth out growing transport costs.

5) Will wire-line companies have to build dual networks or will they be able to support carrier Ethernet over existing architecture.

6) Are their any large local loop carriers today who are positioned well to support dedicated carrier grade Ethernet.

7) If carrier Ethernet, with QOS standards, can be provided as wireless carriers are requesting, are they delusional in expecting the costs to compare with enterprise Ethernet costs? Seems to me that if you want carrier grade, you will have to pay for it.
