在多协议标签交换（MPLS）网络中，标签交换路由器（LSR）不仅可以通过直通机制快速传输IP数据包，还可以解决流量工程问题。在本文中，我们将考虑实时和非实时流量到达LSR的情况，并在直通传输仅应用于实时流量的假设下分析它们的延迟和丢包概率。此外，我们还讨论了带宽分配策略和缓冲区大小以满足实时和非实时流量的要求，并展示了 MPLS 网络中 QoS 配置的指南。
In Multiprotocol Label Switching (MPLS) networks, Label Switching Routers (LSRs) cannot only transmit IP packets fast with cut-through mechanism, but also solve traffic engineering issue. In this paper, we will consider the case where real time and non-real time traffic arrive at LSR and analyze their delay and packet loss probability under the assumption that the cut-through transmission is applied only to real time traffic. Furthermore, we discuss the bandwidth allocation policy and the buffer dimensioning to meet the requirement of both real time and non-real time traffic, and show the guide for QoS provisioning in MPLS networks.
