摘要翻译：
突发争用是光突发交换(OBS)网络中一个众所周知的具有挑战性的问题。争用解决方法总是被动的，并试图基于核心节点上可用的本地信息来最小化BLR。另一方面，在突发损失发生之前避免突发损失的主动方法是可取的。为了降低突发争用的概率，需要一种比最短路径更鲁棒的路由算法。本文提出了一种新的基于JET的光突发交换网络的路由机制，称为图形概率路由模型(GPRM)，它利用贝叶斯网络在逐跳的基础上选择利用率较低的链路。我们假设在OBS网络的核心节点上没有波长转换和缓冲可用。通过在NSFnet网络拓扑结构上使用Network Simulator2(ns-2)并结合实际流量矩阵，在动态负载下对该方法进行了仿真，结果表明，与静态方法相比，该方法降低了突发丢失率(BLR)。仿真结果清楚地表明，该方法在BLR方面优于静态方法。

英文摘要：
Burst contention is a well-known challenging problem in Optical Burst Switching (OBS) networks. Contention resolution approaches are always reactive and attempt to minimize the BLR based on local information available at the core node. On the other hand, a proactive approach that avoids burst losses before they occur is desirable. To reduce the probability of burst contention, a more robust routing algorithm than the shortest path is needed. This paper proposes a new routing mechanism for JET-based OBS networks, called Graphical Probabilistic Routing Model (GPRM) that selects less utilized links, on a hop-by-hop basis by using a bayesian network. We assume no wavelength conversion and no buffering to be available at the core nodes of the OBS network. We simulate the proposed approach under dynamic load to demonstrate that it reduces the Burst Loss Ratio (BLR) compared to static approaches by using Network Simulator 2 (ns-2) on NSFnet network topology and with realistic traffic matrix. Simulation results clearly show that the proposed approach outperforms static approaches in terms of BLR.
