    • A solvothermal synthesis process of the SAPO molecular sieves and catalysts prepared thereby are provided. The synthesis process comprises the following steps: a) an organic amine, an aluminum source, a phosphorus source, a silicon source, and water are mixed in a molar ratio of 6-30:1:0.5-5:0.01-1.0:0.1-15, to obtain an initial mixture for preparing the SAPO molecular sieves, wherein the molar ratio of water to the organic amine is less than 2.0; b) the initial mixture obtained in the step a) is maintained at 30-60° C. to and aged with stirring for not more than 24 hours, to obtain an initial gel; c) the initial gel obtain in the step b) is crystallized at 150-250° C. for 0.5-15 days. The SAPO molecular sieves prepared thereby are used, after being calcined at 400-700° C. in air, as catalysts for acid-catalyzed reactions or for conversion reactions of oxygen-containing compounds to olefins.

    • A method is implemented in a network element that functions as one of a plurality of controllers for one of a plurality of areas of a split architecture network. The controller provides a control plane for the area of the split architecture network where the controller is remote from a plurality of switches providing a data plane for the area of split architecture network. The controller facilitates optimized routing across the plurality of areas of the split architecture network by providing limited intra-area link cost data to other controllers of other areas of the split architecture network and to traditional routers of a network including the split architecture network. The limited intra-area link cost data provides costs of each possible shortest path traversal of the area of the controller without providing all internal link cost data.
    • 一种在分离架构网络的多个区域中的一个区域的多个控制器之一中起作用的网络元件中实现一种方法。 控制器为分离式架构网络的区域提供控制平面,其中控制器远离多个交换机,为分割架构网络的区域提供数据平面。 控制器通过向分裂架构网络的其他区域的其他控制器和包括分离架构网络的网络的传统路由器提供有限的区域内链路成本数据来促进跨分离架构网络的多个区域的优化路由。 有限的区域内链路成本数据提供控制器区域中每个可能的最短路径遍历的成本,而不提供所有内部链路成本数据。
