本文的主题是提出一种新的网络设计算法，它定义了一个有效的多路径路由方案的MLPS网络。我们的目标是提供QoS保证的延迟和抖动被认为是重要的性能指标，交互式和真实的时间服务。为此，我们制定了几个非线性目标函数，用于确定网络链路利用率以及通过网络的流量路由。几个问题进行了描述和模拟，以评估我们的模型。此外，我们还提出了三个负载平衡模块：其中一个模块可以最大限度地减少网络链路利用率，并在延迟方面提供性能保证。第二个模型的目的是选择可行的路径，通过考虑的特性和行为的抖动定义的分裂方案。第三个是一个通用模型的基础上，前两个算法，定义了对延迟和抖动敏感的流量的路由方案。最后，我们的模型与其他多路径路由算法进行了比较，结果表明，QoS参数和网络链路利用率比这些模型有显着的改善。
The topic of this paper is to propose a new network design algorithm which defines an efficient multi-path routing scheme in an MLPS network. Our goal is to offer QoS guarantees for delay and jitter which are considered as important performance metrics for interactive and real time services. To this end, we have formulated several nonlinear objective functions for determining network link utilization as well as traffic flow routing through the network. Several issues are described and simulations are performed in order to evaluate our model. Furthermore, we have proposed three load balancing modules: one which minimizes the network link utilization and offers performance guarantee in terms of delay. The second model aims to select feasible paths by taking into account the characteristics and behavior of the jitter by defining the splitting scheme. The third one is a general model based on the two previous algorithms which defines the routing scheme for traffic sensitive to delay and jitter. Finally, our model is compared to other multi-path routing algorithms, and the results showed a significant improvement of QoS parameters and network link utilization than these models.
