Design and Simulation of Metro Ethernet Using Optical System

Over the years, the discussion about achieving knowledge and discovering unknowns have attracted a lot of people and occasionally a news or text or short understanding of a new science absorbs scholars and people motivated to learn .looking in to the modern technology, we see new inventions and innovations which are unique .as an example, over the past years ,new technology has been created in computer networks of which metro Ethernet has had a Noticeable advance in urban communication. therefore the aim of this article is to provide and compile information regarding metro Ethernet technology. utilizing Ethernet in urban networks need the developing potential and strength that only exist in MPLS and IP levels. layer two and three joint networks are solutions that join simplicity and economy of Ethernet at IP/MPLS scale. Different transfer technologies have been used in metro so metro services should be given on a mixture of optic and data switches, MPLS have been developed for this work and using generalized-MPLScontrol surface that support both data and optic switches performs it .In the beginning theories about using metro technology to produce urban networks are explained. then a simulating called eNSP which is a suitable alternative for simulating metro Ethernet technology and at the end the result of the simulation will be presented.
