wan topology

The topological structure refers to the physical or logical interconnection between computing units in a distributed system. The Topological Structure between nodes has always been an important basis for determining the system type. Currently, centralized and hierarchical topologies are widely used in interconnected networks. Interne is the world's largest non-centralized interconnected network, however, some network application systems established in 1990s are completely centralized, and many w

In the previous blog we deployed additional domain controllers in the domain, and we already know that each domain controller has an Active Directory database with the same content, and today we are going to discuss the replication topology used by the additional domain controller for Active Directory replication. In the NT4 era, domain controllers are divided into two categories, the PDC and the BDC. The PDC is the abbreviation for the primary domai

Many visual editors have more or less drag-and-drop functionality, such as dragging a node from a list to model a topology component, and a drag-and-drop thumbnail at the mouse position during drag-and-drop. First we need to create a list of lists, add the picture information to the list, so that the list is not so monotonous, first look. Next we take a step-by-step to think of this list, first to solve the next data, here I will enumerate one or tw

(' degree ', degree * 2);} In the code, we cache the domain radius of the nodes, stacking them from the bottom up to the top layer. Next we verify its correctness:OK, that's it,2D topology above the layout is done, then the next to deploy a 3D topology ~3. Add z-axis coordinates to render the tree structure under 3D3D topology The above layout is nothing more th

Research on topology control of wireless sensor network based on energy levelabsrtact: in the planning and design of wireless sensor network, it is the first important problem to reduce the energy consumption of the nodes, prolong their working time and maximize the life cycle of the network. This paper designs a topology control strategy based on node energy level, which is designed for excessive energy co

The creation and configuration of topology--a conceptual explanationTopology Manager is primarily used to manage the following 5 categories of tasks and store the information in the master repository for shared use by all modules.Physical Architecture: Define various technologies and their data servers, physical architectures, and physical proxies. Data server blind can build multiple physical scenarios, and the essence of each physical schem

In the previous article, we have prepared Active Directory and installed the management tool. Next we will start to use the topology generation tool to create a topology. After the management tool is installed, four tools are installed by default: lync server deployment wizard, lync Server Control Panel, lync server command line management tool, lync server topology
