The topological structure of telecommunication network
Is mainly star-shaped network, mesh network, composite network and cellular network. At the same time, some basic knowledge of computer communication network is introduced. For communication networks for the purpose of communication, the basic network structure of telecommunication networks is consistent regardless of the business or scope of service. The so-called topology is the shape of the network, network nodes and the geometric arrangement of transmission lines, reflecting the physical connectivity of telecommunications equipment, the topological structure directly determines the effectiveness of the network, reliability and economy.
The topological structure of telecommunication network is a connected graph which describes the adjacency relationship between switching center and terminal. The topological structure of network mainly includes mesh network, star-type network, composite network, ring-type network, linear network, grid grid, cellular network, etc.
