The real time applications have driven the demand for increasing and guaranteed bandwidth requirements in the network. Due to the mobility feature within a MN, mobile networks need a more sophisticated mechanism for quality of service provision. Beside, custom routing methods in a Mobile IPv6 network deliver a packet via specific tunnel this causes intermediate routers do not recognize content of a control packet due to adding headers in IPv6-in-IPv6 encapsulation. In this paper, we propose a mathematical model by using an effective envelope approach to traffic engineering and determine bound of end-to-end delay between MN and correspondent node according to ROMA solution in mobile IPv6 networks. According to this method, every transmitted flow over label switched path should have an end to end delay less than estimated end-to-end delay; otherwise, they will be ignored. This causes an improvement of the network performance and increase achievable link utilization and ultimately increasing quality of services over mobile IPv6 networks. The proposed mathematical model is applicable on label switched path which is a result of ROMA approach to quality of service provision over mobile IPv6 networks.
