Abstract

The invention discloses a three-layer plastic optical fiber Ethernet switch. The Ethernet switch comprises a network management subsystem, a driving subsystem and a switching protocol subsystem which are sequentially arranged in three layers; and routing learning and data packet forwarding are separated in a switching process, wherein the routing learning is realized by a routing protocol run by a central processing unit (CPU) of the network management subsystem, and the data packet forwarding is realized by switching circuit hardware. The Ethernet switch solves the technical problem of the absence of a plastic optical fiber Ethernet switch, has the high capacity of resisting interference and preventing lightning stroke and secrete divulgence, provides an efficient solution on the reliability and security of network communications from a hardware platform and abundant and secure network management functions, and has the functions of network storm isolation, network access authority control, IP address spoofing and hacker attack prevention and the like as core switching equipment in an autonomous system.

Description

technical field [0001] The invention relates to an Ethernet switch, in particular to a 650nm plastic optical fiber three-layer Ethernet switch. Background technique [0002] With the continuous development of the computer network transmission rate, the application of high-speed data information to the desktop in the Ethernet is becoming more and more common. In this process, the Ethernet switch is an indispensable tool. However, the current switches use traditional Category 5 wires, copper cables or quartz optical fibers, which have disadvantages such as inconvenient connection, low coupling efficiency of materials, difficult to bend, not resistant to vibration, not resistant to radiation, and expensive. Plastic optical fiber (POF) is suitable for connection and has high optical coupling efficiency. At the same time, it also has the advantages of softness, bending resistance, vibration resistance, radiation resistance, cheap price, and convenient construction. It can replace...
