The Ethernet frame goes round and round when an Ethernet network includes loop links. To solve this problem, the spanning tree protocol(STP) has been proposed for constructing a virtual tree network on an Ethernet network when the Ethernet network includes loop links. The STP is implemented on various Ethernet switches. The STP suspends some physical links to construct the tree network. These suspended physical links stand by, and they are used for backup when there is trouble on a tree network link. Therefore, all traffic is concentrated on the virtual tree network. Even if traffic is jammed on the network, the suspended physical links are usually still not used. Therefore, in this work, we describe a method that uses Ethernet Bypass Nodes(EBN) so that only communications between specific nodes can pass through the physical links suspended by STP as a bypass to improve communication quality.
