Abstract:
1. A communication apparatus, comprising: a plurality of frame transferring units being provided with a retrieval table for retrieving an output port of a frame and including a switch function unit, wherein the communication apparatus configures a Link Aggregation between the frame transferring units, wherein each of the plurality of frame transferring units causes the states of the retrieval tables to correspond with each other among the frame transferring units by copying a frame determined to be transmitted and received at a port among the ports configuring the Link Aggregation between the frame transferring units and directly transferring the copied frame to a switch function unit of another frame transferring unit, each of the plurality of frame transferring units includes: the unit directly transferring the copied frame to the switch function unit of another frame transferring unit copies a frame which is determined to be transmitted and received at a port configuring the Link Aggregation, outputs the copying source frame to the determined port, attaches information indicating that the frame is a copied frame to the copied frame, and directly transfers the copied frame to the switch function unit of another frame transferring unit, and the unit directly transferring the copied frame to the switch function unit of another frame transferring unit deletes a data part of the copied frame, and directly transfers the copied frame to the switch function unit of another frame transferring unit.
