提出了一种在IP/DWDM光互联网中实现QoS组播路由的并行算法。在给定组播请求和所需的端到端延迟间隔的情况下，该算法将组播路由和波长分配相结合，找到代价次优的QoS组播路由树。事实证明，找到这样一棵树是np困难的。为此，提出了一种粗粒度并行遗传模拟退火算法来构建树。该算法还考虑了负载均衡问题。仿真结果表明了该算法的可行性和有效性。一种新型环四核二硝基铁配合物[Fe(NO)(2)(Im-H)](4)被分离出来，并通过x射线晶体学对其进行了表征。在供体溶剂中，该配合物分裂成17个e（-）单体，其EPR光谱类似于哺乳动物生物学中g = 2.03的物种。
A parallel algorithm for QoS multicast routing in IP/DWDM optical Internet is proposed. Given a multicast request and a required end-to-end delay interval, the algorithm could find a cost suboptimal QoS multicast routing tree by integrating multicast routing and wavelength assignment. It has been proved that finding such a tree is NP-hard. Hence, a coarse-grain parallel genetic simulated annealing algorithm is proposed to build the tree. The proposed algorithm takes load balancing into account as well. Simulation results have shown that the proposed algorithm is both feasible and effective.A novel cyclic tetra-nuclear dinitrosyl iron complex [Fe(NO)(2)(Im-H)](4) was isolated and characterized by X-ray crystallography, and in donor solvents this fragments into 17 e(-) monomeric units that give EPR spectra analogous to the g = 2.03 species seen in mammalian biology.
