Today real-time applications involve, Voice over IP (VoIP) is gaining increasing popularity. MPLS is developed to combine properties of Data-Link Layer with the flexibility and robustness of datagram Network Layer in efficient traffic transmission and QoS support. Connection Admission Control (CAC) mechanism for the RSVP-TE in MPLS network leaks its availability to achieve high performance especially with the increased importance of real-time application that need high end-to-end QoS. So, in this paper, Connection Admission Control (CAC) mechanism is proposed with inputs parameters not only bandwidth but also end-to-end delay and jitter to making its decision. A simulation comparison using OPNET simulator between the proposed algorithm and the most used CAC is presented. The results indicate that the proposed algorithm outperforms the other one.
