Network basics-Network Topology

The network topology refers to the physical layout of devices connected by transmission media. There are multiple ways to connect the various devices involved in LAN work with media. In fact, there are only several ways to fit LAN work. If a network only connects several devices, the easiest way is to directly connect them together. This connection is called a po

Figure I Diagram one topology in four servers and load balance directly connected, each server dual network card connection One load balanced, load bala

Research on Network Topology Discovery Methods of the Ethernet link layer (Xiaogang, reserved for use)

SummaryThis paper analyzes the existing Ethernet link layer topology discovery algorithms, proposes improved algorithms, and provides the basic implementation methods of the algorithms. The new algorithm relaxed the conditions in the original algorithm, making the algorithm more widely used and adaptable. The new algorithm can discover devices that cannot be found by the original algorithm in the network.

Common LAN topology and network system applications (1)

generally the use of generic twisted pair wires, this transmission medium is relatively cheap, such as the current genuine cat5e twisted pair wires per meter is only about 1.5 yuan, the cheapest coaxial cable is about 2.00 yuan a meter, not to mention the cable. This topology is mainly used in IEEE 802.2 and IEEE 802.3 standard Ethernet LAN; 2) node expansion and mobility convenience: you only need to pull a line from the hub or switch and other cent

Advantages and disadvantages of Computer Network Topology

limited. (2) It is difficult to diagnose and isolate faults. (3) distributed protocols do not guarantee the timely transmission of information and do not provide real-time functions. 3. ring topology A ring topology consists of links of sites and connected sites. Advantages of ring topology: (1) Short cable length. (2) When adding or removing workstation, you on

Getting started with the front end: rapid development based on HTML5 network topology diagram application

The topological structure of computer network is a method to study the relationship between the point and line in the topological research and the size, shape-independent. The computer and communication equipment in the network is abstracted as a point, and the transmission medium is abstracted as a line, and the geometry composed of dots and lines is the topological structure of the computer

Why use the leaf-spine topology network? (1)

Why use the leaf-spine topology network? (1) The structure of the three-layer network has developed very mature, but the leaf-spine (leaf node, spine ridge node) structure is becoming more and more popular. How should network designers choose? Despite the wide application and mature technology of the layer-3
