If you could choose isolated one technology for your wide sphere network .... metro ethernet or MPLS .... which would you choose and why?

Keep in head this is not a lucid bandwidth concept question. Such as choosing "how much" .... between assert DS3 bandwidth or OC3 bandwidth. This goes to the affection of designing your network infrastructure.

First off ..... you itch to explain that they are not mutually exclusive. I would adoption Metro Ethernet as an access technology .... and a Layer-3 technology, such as MPLS, for my backbone. The request of MPLS is the Affirmation of Avail (QoS) capabilities it offers.

The backside path when choosing a WAN technology is the bill compared to bandwidth and redundancy capabilities. Supply providers submission indefinite flavours of homogenous technologies, so unless you posses the specifics, its ambitious to compare.

Be conscious of the naked truth that when you deliver WAN services to a remote site, you testament always be relying on a regional convert carrier (LEC) to deliver the "last mile" services. Most problems with WAN course outages at remote aegis are physical layer issues at a CO that is the LEC's responsibility. This is of specific drift whether you charge to deliver services in a conurbation or rural existence with a out of date infrastructure. In this regard apt vendor choice could truly prove extended foremost than technology.

Indeed these are not necessarily mutually exclusive - there are technologies such as VPLS which is a Metro Ethernet novel of MPLS. The quantity one component is what cook you NEED? Are all of your sites that obligation this connectivity within a metropolitan field and is there a unmarried provider who is offering Ethernet access to all of these locations? Provided the give back is "no", then the choice is sunny - MPLS, which is quite everywhere these days.

MPLS is expanded correct for a contrary network with multiple connexion speeds and multiple stakeholders, largely in situations where you're looking to bring about CBR. Metro Ethernet is cool used in exceeding of a "bridge" (I call the word loosely!) situation, connecting physically-separate support where each is busy in analogous grindstone or at least working for the duplicate division. The reality, of course, is that a accepted installation consists of Metro Ethernet interconnects and an MPLS backbone, on the other hand I said "choose one".

From my perspective it would accept to be MPLS, purely for the flexibility of access methods and transports supported, the scalability of bandwidth demands, and of course, the QoS and traffic prioritization capabilities. Again, the end of MPLS does not preclude MEN, nevertheless MPLS would be my overarching choice if pushed.

In sum, sadly, analogous indefinite pc networking questions, the repay is, "It depends."
