Ethernet or OC3 Bandwidth - What to choose?

Ethernet or OC3 bandwidth is the right choice for a network solution for your company? How to take this decision?

When it comes to a network operator / service provider and if the links are about 1 Gbit / s .... probably need both / and Ethernet OCX EOS. Finally, you must connect to other networks. If the sides 1Gbps link below to access or core network, then you would use OCX for the most part. Although some people tend toWe say that a new network, you can do whatever you want, the reality is another matter.

OCX / STM-N are known for their reliability and predictability, and still have a good long-distance legs. These are migration EOS (VCAT, LCAS, GFP) and OTN but are not satrt to Ethernet "pure" about 43g and it is assumed that there is no difference in 100G Ethernet could be dominating the adoption of some of the factors and compatibility reliability of DWDM OTN. It 's still a long way to gothat the first true convergence. In fact, work together HSSG IEEE and ITU-T to make sure that no one invents the other wheels. Maybe if you could join, we would see a single physical interface can handle both Ethernet connectivity end-to-end applications and OTN transport.

If you are farsighted, maybe you need to carry the OTN and EOS / add core infrastructure, so they prepared for the future and more flexible on other peers with OCX or interconnectionProvision of services under a single GigE with EOS. People say they have "pure Ethernet" from their suppliers may not have the attention of the EOS add / drop box that came with the service contract and return, in fact, receiving packets and the shooting on the OCx seat frames, or came at a meeting place near via OCX / EOS and then the radio (perhaps an internal link customer premises to OCX).

Below 1 GigE prices (I think) there's no good way to offerEthernet directly to the customer (Access Network). It must always be on some sort of (unreliable) transport scheme as VDSL, SHDSL, DOCSIS, wound ... This is (I think) having SONET / SDH vivo. After that we all have fiber and beyond 1GigE there is no problem. You would be able to go Ethernet / OTN across the street.

While Ethernet is distributed fairly widely accessible and cost, are often the positions A and Z, a decision in favor of OC3. SONET can readilyit may be more cost effective (yes - even taking into account the form of WAN OC3) in some places. For the same A and Z positions, if both Ethernet and OC3 are available, I would like to take the easy integration of Ethernet, while the costs within ~ 65% of the OC3 circuit.

OCx has the capacity and performance history, and is subject to the ranking supplier for every last cent of it as an asset against the evolution of the long (er) distance Ethernet.

"Choose wisely," said the TemplarKnight in Indiana Jones and the Final Crusade ... here. If you are committed long-term contract for OCx not extend it to say, then, your business and application requirements, you do not need flexibility Metro-E at the end of the grace period. to negotiate for concessions, too large and / or free upgrade to Metro-E at the end. Since the price competitiveness of services in the amount of market share based on Metro-and / 10GB nano in time-and OCX.

Finally, chooseOCX / Metro-E service is based on achievable and measurable SLA at first ..... then nail the supplier on the floor on the price (as you do .... or .... you should do).
