服务质量(QoS)和流量工程(TE)能力是当今支持实时应用的网络中的两个重要标准。多协议标签交换(MPLS)通过提供QoS和TE功能在IP网络中起着关键作用。在本文中,我们首先提出了一个分析标签交换路径(LSP)模型与TE问题,假设两个不同的LSP传输机制:第2层直通交换和第3层默认路由。其次,我们提出了一个新的LSP流量分配优化目标函数,以最大限度地减少整体网络传输延迟。仿真结果表明,该模型能最大限度地减少总时延,并使各链路上的流量分布均匀。换句话说,第2层交换技术的面向连接的转发特性,实现了在所提出的模型和合并的目标函数,同时保留了同样理想的灵活性和可扩展性的第3层路由。
Quality of service (QoS) and traffic engineering (TE) capabilities are two important criteria in today's networks for supporting real-time applications. Multiprotocol label switching (MPLS) plays a key role in IP networks by providing QoS and TE features. In this paper, we first propose an analytical label switched path (LSP) model associated with the TE issue that assumes two different LSP transmission mechanisms: layer 2 cut-through switching and layer 3 default routing. Secondly, we propose a new LSP traffic flow distribution optimization objective function to minimize the overall network transmission delay. The simulation results show that the proposed model minimizes the overall delay and distributes the traffic on each link evenly. In other words, the connection-oriented forwarding characteristics of layer 2 switching technology are achieved in the proposed model and the incorporated objective function while retaining the equally desirable flexibility and scalability of layer 3 routing.
