Description

field of invention [0001] The invention relates to a relay system of a network, in particular to a relay system of an Ethernet passive optical network (EPON) and a use method thereof. Background technique [0002] With the continuous improvement of IP (Internet Protocol) technology, IP technology has been used as the main bearer technology of data network. From this, a large number of access technologies based on large network technology have also been derived, and Ethernet over PON (based on Ethernet passive optical network) combines simple and economical Ethernet technology with the transmission structure of PON (passive optical network). ) concept, since 2000 has attracted extensive attention from the technical circles and network operators. In December 2000, the IEEE (Institute of Electrical and Electronics Engineers) 802.3 working group set up a special working group EFM (Ethemet in the First Mible) (Ethemet in the First Mile) to study and formulate EPON standards. In...
