Metro Ethernet - Coming to a Metropolitan City Near You
Ethernet technology is based on the idea of computers connecting with each and communicating using a cable.
It was developed in 1973 and has been widely in use since then based on technologies of LAN, MAN and WAN.
It was later accepted and standardized by IEEE and is famous and now in use since its inception.
Metropolitan Ethernet covers the whole of metropolitan and as its name suggest it is based on Ethernet technology.
Businesses and even government agencies can make use of Metropolitan Ethernet which is by default intranet and provides security and reliability along with communication.
It is especially used for companies who do not want to share their data through internet and would like to keep the information within the company.
It is not as fast or as advanced as internet but fast enough for businesses to feel secure using it.
There are many different options for installing metro Ethernet in you office such as the Pure Ethernet MAN, the Ethernet over SDH or Ethernet over MPLS.
Pure Ethernet is cheaper than the two other but it not flexible enough and neither it is much reliable.
It is only good enough for small businesses and not with a lot of cash.
Ethernet over SDH for MAN is more reliable than pure Ethernet but it also very costly.
Since it has a rigid structure, it does not offer much flexibility.
Ethernet over MPLS for MAN is the fastest one and is very reliable, secure and even flexible but it is the most expensive of all.
It is recommended for businesses that have branches and require a lot of exchange of information and cannot afford delays.
Keeping in mind the three installations, let see the advantages and disadvantages of Pure Ethernet.
Pure Ethernet as said before is good for small businesses that do not have more than a few hundred users.
But it is not reliable and stops working when more users join in to use it.
Since it is based on Level 2 switches, the switches cannot work beyond a certain limit and its limits cannot be increased.
To enhance its capabilities some non-standard installations are used and since they are not standardized, they are much less reliable.
Ethernet over SDH has a rigid structure whose limits cannot be expanded.
Also, it is expensive and not cost-effective due to its expensive equipment.
Other than that it has a very fast response time and is much reliable and secure than pure Ethernet.
It can be used for medium sized businesses that want to step over a bit from traditional methods of MAN installations.
It has tool that can help in troubleshooting on network problems.
Ethernet over MPLS is the fastest of all and can be expensive and used for large businesses that have branches and lot of information traveling back and forth from these branches.
It is extremely reliable and secure as well.
However, its diagnostic and troubleshooting tools are very well developed and can be trusted in case of trouble.
