Short-term QoS provisioning in MPLS ingress nodes

Abstract

In this paper, we propose a new switching scheme to improve the short-term delay and the packet jitter for real-time traffic. Even though, the proposed scheme is general and can be used in different points of the network, we propose to use it in MPLS ingress nodes. In our plan, we manage the delay to improve the QoS provisioning in a flexible manner, since traditional mechanisms such as leaky bucket can not have such kind of flexibility. Also, after using the scheme in MPLS ingress node the impact of short-time scale burstiness of the traffic will be decreased. The performance analysis shows that high quality of service provisioning for the real-time traffic will be achieved.
