Design and Optimization of Metropolitan Area Networks using Multi-Protocol Label Switching

Looking in to the modern technology, we see new inventions and innovations which are unique. As an example, during the past years, new technologies have been created in computer networks like metropolitan area network (MAN) that has had a noticeable advance in urban communication. Therefore the aim of this article is to provide and compile information regarding MAN technology and MPLS. Utilizing Ethernet in urban networks needs a developing potential and strength that only exists in MPLS and IP levels. Two layer and three joint networks are the solutions that join simplicity and economy of Ethernet at IP/MPLS scale. Different transfer technologies have been used in MAN so metropolitan services should be given on a mixture of optic and data switches, MPLS have been developed for this work and using generalized-MPLS makes MPLS deployments possible even on none-IP-aware switches. At first, theories about using MAN technology to produce urban networks are explained. Then a set of problems regarding the management of resources and provisioning barriers are introduced following the solutions by means of IP/MPLS network which have been implemented and validated in eSNP simulator.
