Metro Ethernet & Carrier Ethernet


In the Communication Service Provider (CSP) industry today, there are many confusions with terms. One such example is Metro Ethernet (ME) and Carrier Ethernet (CE).  Many people have asked me the difference between the two. Therefore, I just though of writing this small blog, just to clarify the doubts.

ME was 1st to come. Hence the Metro Ethernet Forum (MEF). Carrier Ethernet (CE) came later and MEF adopted it as well. So, MEF the one defines the generic standards for ME and now CE.

Both ME and CE, though technical terms, are used as commercial words these days by vendors.

ME is a service. CE can provide ME services too. ME and CE demarcation is now becoming blurred and the future term will be CE.

In fact CE and ME refers to the same thing, i.e well known Ethernet technology/interface used in the Local Area Network (LAN) being used in the Metropolitan Area Network (MAN) and Wide Area Network (WAN) with hardened capabilities, defined as 5 attribute by MEF.

New strategies for Telcos

The Telcos (more correctly, Communication Service Providers (CSPs)) face a severe competition and a pressure today to keep their noses above the water. They can no more sell voice and bandwidth and make that a viable business proposition. Both voice and bandwidth has become a given. Most of the customers granted that as given. Recently the United Nations (UN) has accepted Internet access as a basic human right.

CSPs over the years have built their transport networks (Core, Aggregation and Access). In developing countries, the expansion of wired access networks seems to be prohibitive with the associated cost and the demography. The incumbents specially, have started copper based access networks from the urban areas and started expanding toward the sub-urban and rural. Most of the cases we find that the  already invested infrastructure delivers Plain Old Telephone Service (POTS) services to the customer and there's a huge potential that most of them can be enabled with broadband. Even with that, the total wire based coverage will still be less than 50% of the households. As you reach the rural areas the demand is more scattered and for a developing country, the only viable option is wireless.

If the balance households are reached using wireless, and an acceptable pipe is delivered to the household or individual, just by selling voice and Internet will not make the CSP win. The Average Revenue Per User (ARPU) has saturated and CSP have to think how they can make the customer spend more. The old form of merely satisfying  their communication, information and entertainment requirements is not just enough. We have to think selling the "convenience"  to the user. One example of selling the "convenience" is the e-banking introduced by the banks. People are prepared to pay a premium to this facility as they can make all their bill payments electronically.

The CSPs need to this considering the total Information Communication Technology (ICT) ecosystem, making sure all stakeholders are benefited. Just take an example. The CSPs are good at building networks (providing the transport), but they may not be good at  producing applications to run on all three screens (computer, mobile and TV). On the other hand, the software companies can produce applications (of course after a good socioeconomic study ), but they can not build communication networks. Both CSPs and software companies can get together in a win-win arrangement to provide a service to the customer. The applications so developed need to be based on the principle of "convenience".

What will happen to our digital life/data when we die?

Most of us use multiple email accounts, blogs, subscription to email lists, social networks, web sites etc. In the future with web2.0 and web3.0 we'll be using the Internet more often and the www, and intern we'll be putting lot of data/information online. But when we die, what will happen to all these? I know that there are some mechanisms to close down some of the services if are not used/inactive for some defined period of time.

There was a cartoon some time back saying " on the Internet, no body knows you are a dog". So, is it correct to say " on the Internet no body knows you are dead"?

Have you ever thought of this? What do you think?
