Abstract
This paper presents analysis of the performance modeling of the mean queue length and the mean queueing delay in MPLS (Multiprotocol Label Switching) LER (Label Edge Router) through the application of GE/G/1. We consider traffic with inter-arrival times of external arrivals at queue having generalised exponential (GE) distribution. The choice of the GE distribution is motivated that measurements of actual traffic or service times may be generally limited and only few parameters can be computed reliably and GE has a pseudo-momoryless property which makes the solution of queueing system and network analysis easily controlled or dealt with. From the analytical results we obtain the mean queue length and the mean queueing delay in a non-preemptive HOL (Head of Line) with two priority classes. We provide a framework including closed expressions and compare the mean queue lengths and the mean queueing delays at different traffic intensities. These numerical results can be useful for determining the amount of traffic entering from the external network for an MPLS LER system.
