3. Introduction
MPLS (Multi-Protocol Label Switching) is a fast packet based - forwarding and scalable technology, which is widely used in the core network.
It comprises of three stages of operation: IP – MPLS (LER ingress), MPLS – MPLS (LSRs), and MPLS – IP (LER egress)

4. Mobile and Wireless application services form the basis for the success of the technology in the next generation of networks.
Management of the bandwidth has emerged as a powerful platform for controlling the traffic volume of future mobile and wireless networks.

5. Aim and Objectives
Aim to study the performance of multimedia services in MPLS Network model using a simulation approach. This will eventually proffer a solution to the bandwidth issues of the next generation of Mobile Wireless networks.
To perform the evaluation of Label Distribution Protocol signaling with dynamic Label Switch Paths and Bandwidth Allocation in MPLS Network model.
Performance analysis of the MPLS model with control and fast forwarding technique will be required to minimize packet loss and packet delay along switching process.

7. Two Signaling Protocols
LDP can signal three types of transport Label Switched Paths (LSPs):
MP2P
P2MP
MP2MP
RSVP-TE builds two types of LSPs:
P2P

8. Label Distribution Protocol (LDP)
In order for MPLS to operate correctly, label distribution information needs to be:
Transmitted reliably
Transmitted in sequence
