Transmission system, transmission apparatus, destination management apparatus

摘要

A transmission system including: transmission apparatuses; and a destination management apparatus including: first ports which are coupled to the transmission apparatuses; and a first processor configured to manage an address entry which indicates a relation between the first port which receives the frame from among the first ports and a transmission source address included in the frame; and to transfer the frame received by one of the first ports, to the first port in association with the transmission destination address from among the first ports based on the address entry, wherein one of the transmission apparatuses including: second ports which are coupled to another transmission apparatus in the network; a third port which is coupled to the destination management apparatus; and a second processor configured to transmit the frame received by one of the second ports only to the third port.

1. A transmission system comprising:
a plurality of transmission apparatuses to transmit a frame in a network; and a destination management apparatus that includes,
a plurality of first ports coupled to the plurality of transmission apparatuses to transmit and receive the frame; andfirst circuitry configured,to manage a first address entry which indicates a relation between the first port which receives the frame from among the plurality of first ports and a transmission source address included in the frame; andto transfer the frame received by one of the plurality of first ports, to the first port in association with the transmission destination address from among the plurality of first ports based on the address entry; wherein one of the plurality of transmission apparatuses includes,
a plurality of second ports coupled to transmit and receive the frame from at least one other transmission apparatuses in the network;a third port which is coupled to the destination management apparatus;a storage unit to store a second address entry indicating a relation between the second port which receives the frame from among the plurality of second ports and the transmission destination address included in the frame; andsecond circuitry configured to transmit the frame received by one of the plurality of second ports only to the third port instead of the plurality of second ports, when the second address entry related to the transmission destination address included in the frame is not stored in the storage unit.
