Abstract

To eliminate the problems related to the Internet Protocol (IP) network, Multi-Protocol Label Switching (MPLS) networks the packets, they use label switching technology at the IP core routers to improve the routing mechanism and to make it more efficient. The developed protocol configure the data packet with fixed labels at the start and the at the end of the MPLS domain, it also allows a service provider to provide value added services like Virtual Private Network (VPNs), MPLS is faster than the standard method of routing and switching packets of the data. MPLS traffic engineering (MPLS TE) provides better utilization of network recourses, while MPLS offers VPN implementation and interconnected with other networks to gain secure and reliable communication, MPLS was improved to support routing functionality on conventional service provider IP Network. MPLS permit service providers to provide customer support services, and It naturally supports Quality of Service (QoS) by providing classification and marked package, avoid congestion, congestion management, Improve traffic, and Signaling. MPLS is not complex at all, and there is no need to any changed in the network structure because it uses one Unified Network Infrastructure. Also, no need to run Border Gateway Protocol (BGP) in the core of MPLS network, this will increase the efficiency of Internet Service Provider (ISP). Therefore MPLS provide the reliability of communication while reducing the delays and supporting the speed of the packet transfer.
