In MPLS, a key issue is the accumulated delay experienced by traffic trunks. Another key issue is the load distribution over multiple disjoint LSPs. These two key issues are related each other. The load distribution model must take the QoS constraints into account, and one of the primary constraints is the traffic trunk delay. In the literature, most reported load distribution models are based on the Markovian delay bounds. Although the inadequacy of the Markovian models for IP traffic has been extensively reported and several non-Markovian delay bounds have been proposed, relatively little was done toward establishing new load distribution models. This paper seeks to fill the gap. We present several MPLS models based on a non-Markovian delay bound. Solutions and examples are provided also.
