It seems a lot of hype all the support over Ethernet to the Internet and private networks. However, the reality is quite different. There are a limited number of Ethernet-enable-lit buildings in the U.S. and around the world.
If your office is located in a burning building, Article or carrier hotels, great! You can get up to 100 Mbps Fast GigE ports or even 10GigE. Many companies are not illuminated buildings, but they are close enough to get to 10 Mbps Ethernet over copper (EOC) or DS1 (EoDS1) or up100 Mbps Ethernet over multiple DS3s. Most distant from Ethernet POPs can, to more traditional options, such as DSL, T1, DS3 or NXT1 be limited.

Do not think that Ethernet is a great revelation. This has two different problems. The first ..... due to a large "step" is risky and generates a lot of unknowns. The second ..... the fact that Ethernet can be served at the customer tends to have asked 10-15 years ago. If you want to go back and check ...... It recognizes most ofsame promises of ATM and ISDN comparison.
The standard Ethernet protocol does not solve, such as small size of ATM rich. But no solutions in the level of the control group, the most developed in ATM or even MPLS.
However, there are two main differences compared to "then." The Ethernet hardware technology is currently in use is relatively cheaper than ATM 10-15 years. Telco is more depressed, down to the old hardware. It also increases the closer to the total cost of ownershipIncome, such as the 5ESS and PP8600.
From the latest communications technologies available to the real revolution is technologies such as MPLS ..... or more, the 3G mobile phone to control the level. If the service is presented to the customer ..... and the core supports an important plan of management to control services .... is not so difficult to provide services. This would be a revolution ..... due to the fact that the customer determining what serviceswant from the customer premises. This step is not more important, if the technologies are used in Ethernet or POTS. And 'the service of things ..... as QoS and SLA.
Today ..... the largest mobile phone provider are far from challenging their counterparts from the Carrier Ethernet fixed, as part of a growing dilemma for the supply of large amounts of data / media for the handset. In recent years, mobile operators have discovered that the data is no longer the bottleneckListeners, but the delivery system in the cell sites. Traditional T-1 architecture is always an expensive pill that mobile operators do not want to swallow. The alternative is radio access network aggregation Pseudowire (PWE) technology for current systems RAN ..... Finally, the parcels are delivered on native and newer versions of RAN architecture. All this would be done over Ethernet.
Here are some issues of interest -
1) Will the Board ofWire-line companies to see beyond T-1 delivery for mobile operators as a whole? And 'cost-effective for them or continue to use traditional TDM architecture to enforce.
Applications of copper 2) Will have a place stuck in the delivery carrier Ethernet, fiber, or should we expect the only means of transport?
3) PWE3 standards as a reliable T-1 emulation and the delivery system is to detect?
4) If the carrier-class metro-and find a place in the LEC-portfolio? WillAvoid problems of latency and jitter that mobile operators to move in order to regulate this form of transport, in an attempt to transport costs on the rise.
5) It will be wire-line companies have created two networks, or will be able to support carrier Ethernet over existing architecture.
6) There are major carriers unbundled today that are well positioned to support the specific carrier-grade Ethernet.
7) If Carrier Ethernet with QoS standards that can be made available as a wirelessCarriers ask, are delusional to compare in anticipation of the cost for companies with cost Ethernet? It seems to me that if you want, carrier-class, you must pay for it.
Remember, there is hardly a significant difference between ATM and Ethernet-live. The only real difference is the price and the amount of impact on the implementation costs of such products. The Ethernet products, which are still very different ...... ADSL and ATM, as onceOnce upon a time. Finally, you'll probably see a consolidation of the nature of each. But then ...... History tells us that the risk of creating new technologies. If this happens ...... only operators with limited services to the board will be flexible enough to accommodate the "new" low cost and reduced impact of technological change.
