Abstract
The Multi-protocol Label Switching is one of the proposed technologies useful for traffic engineering in the specific aspects of measurement and control of Internet traffic and virtual Private network (VPN) is a concept that significant on the future of business communication, it replace existing private network with flexible architecture that is easily manage and at a same time it provide enhanced service.
The Multi-protocol Label Switching (MPLS) virtual Private network (VPN) is a popular IP VPN service based on RFC 2547 and its successor documents (dubbed 2547bis).The main importance of MPLS is that it integrates the key features of both Layer 2 and Layer 3. Most importantly, it is not limited to any Layer 2 or Layer 3 protocol. In particular, MPLS has several applications and can be extended across multiple products segments (such as an MPLS router, an IP services switch/router, a multi service switch, an Optical Ethernet switch, as well as optical switches). Many service providers offer MPLS VPN to their large enterprise customers, who need only attach their local, customer edge (CE) site routers to the nearest service provider edge (PE) router and exchange routing information. MPLS reduces the complexity of forwarding using encapsulated fixed-length labels for making high speed forwarding decisions. The service provider distributes customer IP routing information to other customer sites and uses its backbone to forward customer IP packets from one customer site to another. This is done by very new concept which is called multicast virtual private networks (mVPNs).
