Although the fact that VPN provide a safe and reliable transfer of customers’ data,

With the rapid growth of the Internet and increase the load on the network in terms
of users and providers of service to look for ways of effective and fast routing packets of
data while ensuring quality of service began(QoS)and class of service(Cos)and secure
management and engineering movement(traffic) on the network and appeared the multiswitch
tags of the Protocol(MPLS)standard modern technique verify the previous
requirement safter she was initially way to improve the transmission speed routers.
This paper presents an analytical study on improving the performance of virtual
private networks using multi-protocol label switching( MPLS_VPN), by improving routing
operations on the third level, minimizing the delays and complexity resulting from the
routing on full internal routers in the traditional technical protocols settings and limited to
Edge routers in networks MPLS_VPN.
OPNET was used simulation software to get the results of the analysis and
simulation of new technology and compare it with the old technology.
