The development of information and communication, especially the Internet in recent
years make a revolution to many aspects of a life.Telecommunications networks have been
developing new and advanced technologies, especially optical communications. Optical
communication system is considered to be the most development potential in
telecommunications now with the advantages of wide-band transmission and allowing for the
necessary information in the form of digital signals, transmitted information doesn’t effecting on
the electromagnetic and high security.
Being a network layer technology used to route information on the network in OSI model, IP
internet protocol became the popular standard protocol for new network services, which IP
traffic will increase rapidly and replace for other networks. Advanced optical WDM technology
is not only get a rise ability amount of bandwidth but also maintain the working status of
network. It is also considered an optimum solution in term of cost for long haul networks.
Although two protocols IP and WDM are independent of each other, they can integrate the IP
traffic into transmission in WDM optical network, which has solved problems of network traffic
and has created developmental momentum for the telecommunications networks and much kind
of services. IP/WDM networks to comply with the multi-layer network protocols. Intermediate
class will provide the functions as well as traffic engineering. How to control the flow of lightpath when these functions come down WDM optical network? To solve this problem, routing
and wavelength assignment have to be determined.
The last IP/WDM network developed in this thesis considers “performance analysis of WDM
optical network” which uses in all optical network (AON).In all optical networks, the network
construction is not successful and has some assume. This problem will mention by theoretical
and modeling them based on simulation Matlab. |
