Ethernet MPLS (multiprotocol label switching) is a recent technological break-through that allows MPLS networks to utilize far more bandwidth at considerable cost savings.
MPLS networks are state-of-the-art any-to-any location WANs (wide area networks) that can be fully managed by providers.
With the use of Class of Service (CoS), MPLS networks can efficiently accommodate multiple applications, like VoIP, video conferencing, or routine data traffic over one large data pipe of a network.
Prior to the use of Ethernet with these networks, customers had the flexibility to choose between T1, bonded T1, DS3 or OC3 (fiber) speed for each location of their network.
There are many advantages to this. As an example, in the past, if a customer needed a ten megabit per second (mbps) circuit at a location of their network, they would have had the option of paying approximately $4000 per month for a 10.5 mbps seven bonded t1, or about the same price for a 10 mbps fractional ds3. Now that Ethernet can be utilized, this same bandwidth can be obtained in the form of Ethernet over copper (EoC) for about $1200 where EoC is available. As another example, Ethernet over ds3 and 88 mbps Ethernet usually offers far better prices than DS3 for locations where these forms of Ethernet are available.
Ethernet service comes with the same service level guarantee as t1 and ds3. As inferred earlier, the major disadvantage of Ethernet at this time is that it is only available to about 50% of all business locations. However, because all types of bandwidth can be used in a single MPLS network, depending on the offerings of the provider, it is not uncommon for the majority of the locations of a network to utilize Ethernet while the rest use t1 or ds3.
