What are the differences between routers, trunks, and bridges?
Bridging refers to the process of forwarding network packets according to the address of the link layer of the OSI network model, working on the second layer of the OSI. A general switch bridges the bridge.
With the development of science and technology, the concept of relay is applied not only in wireless communication, but also in the trunk of network communication switch. In daily life, we often have to talk to friends through home phone calls, or contact clients outside the office via office phones. These calls can not be achieved without relaying.
Relay (Relay) is a transmission path between two switching centers. A relay is a physical connection that carries multiple logical links.
