What Is a Computer Network Diagram?

Computer network topology (Computer Network Topology) refers to the distribution and connection status of devices between a network of computers. Drawing two of them on the map becomes a topology map. Generally, the location of the device is indicated on the map. , Device name type, and the type of connection medium between devices. It is divided into physical topology and logical topology. ^[1]

Computer network topology

The advantages and disadvantages of several common topologies are analyzed above. Whether it is a local area network or a wide area network, the choice of its topology needs to consider many factors: the network must be easy to install and easy to expand; the reliability of the network is also an important factor to consider, and it must be easy to diagnose and isolate, so that the main body of the network Can still function normally when a local failure occurs; the choice of network topology will also affect

First, the deployment personnel should be familiar with the computer network topology of various networks, list the computer network topology suitable for them, and then screen them one by one.
No computer network topology is universal or adaptable to all businesses and companies. As a technician, you must first be familiar with the computer network topology, such as using a gigabit or 10 gigabit backbone network according to the budget, so as to help you solve the technical problems of the network.

Computer network topology data center computer network topology

At present, the main computer network topologies of most data centers are built based on layer 3 protocols. A typical structure is to connect a second-level switch or other network equipment through a core switch, including the user layer and the aggregation layer of the external network and the internal network.
Leaf nodes and spine nodes are the most important and obvious parts of the data center computer network topology, referred to as leaf-spine. With the increase of switch equipment, this kind of computer network topology will cause bottlenecks in transmission. For example, the data traffic of the storage area network will be affected by the increase of such switch nodes.

Computer network topology

The new computer network topology design is a dedicated channel computer network topology. Specific applications use dedicated network channels. This computer network topology design theoretically considers that devices within the network can move physical locations freely and inherit them. The characteristics of the traditional computer network topology switch forward data. Although the current mainstream computer network topology does not seem to use these technologies, the maturity of emerging technologies always takes time to verify, maybe not now, but as next-generation technologies, there is a lot of room for development in the future.
There are also some other new computer network topologies that have been formed. These emerging computer network topologies have surpassed traditional third-level leaf-spine computer network topologies. Although these computer network topologies are rare. Because these computer network topologies are mostly used in data centers in special fields.
The multilayer leaf-spine computer network topology is very close to the baseline of the computer network topology. Many large networks use vertical deployment methods to extend the network, such as VLANs.
Hypercube cube computer network topology . A simple 3D Hypercube structure is like a three-dimensional square network composed of six faces, and each connection point is composed of a switch. A 4D Hypercube network is like a 3D Hypercube network located in another 3D Hypercube. The two networks inside and outside are connected to each other through corner nodes, and the device nodes are connected to the outer network. To implement such a computer network topology, you need to understand your needs and budget, and you need to understand in detail what the characteristics of this computer network topology are.
Toroidal ring computer network topology . This computer network topology actually refers to any ring computer network topology. A 3D ring computer network topology is a highly structured network ring. Ring computer network topologies are often used in environments that require high-performance computing and may rely on interconnected nodes between switches for computing.
Jellyfish jellyfish computer network topology . It sounds strange, but it fits its name. The main feature of this computer network topology is that it is a large random computer network topology. The switches of this computer network topology are connected to each other according to the design of the network designer. The design of this computer network topology structure can increase the data capacity by even 25% compared with the traditional structure.
DCell computer network topology . In this computer network topology, servers in the network have multiple network cards. Some of these network cards are connected to each other, and the server is like a cell in a large network environment. DCell generally requires four or more network cards per server.
FiConn computer network topology . Similar to DCell, in the FiConn structure, the interconnection of each computer network topology server to another server forms a cell node, but only two network cards are required.
BCube computer network topology . Like DCell, FiConn, BCube connects directly using additional server ports, these ports are designed for modular network deployments. Microsoft mainly promotes the BCube computer network topology and establishes the BCube source routing protocol to manage the computer network topology of the network data center.
CamCube computer network topology . The purpose of this computer network topology is to optimize the data transmission of the entire torus. The computer network topology is used to interconnect cluster hosts. The computer network topology is built on Microsoft's CamCubeOS. Traditional computer network topology management does not work on this network structure.
Butterfly computer network topology . Google's flat butterfly structure is a specific computer network topology, similar to a chessboard. In this network structure, any node can be used as a switch, and the node controls the traffic. The purpose of this type of network is to reduce power consumption, which is of environmental protection significance. ^[2]
