The invention provides an Ethernet port architecture supporting multiple transmission modes. The Ethernet port architecture at least comprises a first scene module which corresponds to a first transmission mode and comprises a first Mac module and a first Pcs module which are connected with each other, a second scene module which corresponds to a second transmission mode and comprises a second Mac module and a second Pcs module which are connected with each other, and a serdes module which is at least connected with the first Pcs module and the second Pcs module, wherein the first scene module and the second scene module multiplex the serdes module and correspondingly switch the first transmission mode and the second transmission mode according to configuration. By the Ethernet port architecture, the single architecture can support multiple transmission modes; the chip cost is relatively low; and the Ethernet port architecture is flexibly applied.
Description
technical field [0001] The invention relates to the technology in the field of Ethernet, in particular to an Ethernet port architecture supporting multiple transmission modes. Background technique [0002] With the development of network technology and the popularization of information applications, Ethernet switches have been more and more widely used. Different application scenarios have different requirements for the port form and transmission rate of the switch. For example, a certain type of application does not require many ports, but requires a relatively high switching speed, while another type of application requires more The number of ports, but the requirement for switching speed is not too high. Therefore, an Ethernet switch chip that can support multiple port forms and transmission rates has become an indispensable core component for building a flexible Ethernet system. [0003] In the prior art, in order to expand the switching rate and the number of ports su...
