This section explains the Multilink Ethernet round-robin distribution method.
In round-robin distribution method, the Multipath function transmits data by distributing it evenly to the component NICs.
This method is effective for normal use because it does not exclusively use the redundant components or NICs whereas the Multipath and MAC address distribution method do.
However, as noted below, this might not lead to improved transfer performance.
"Figure 1.6 Transmission data flow in round-robin distribution method," diagrams the transmission data flow in round-robin distribution method.
[Figure 1.6 Transmission data flow in round-robin distribution method]
- The CPU load rate increases in proportion to the number of NICs used.
- In round-robin data distribution method, the sequence of transmitting and receiving data cannot be guaranteed because it is affected by data delays and deletions caused by the processing sequence and transmission path noise on the local system and the switches for connection.
Therefore, it might be necessary to re-transmit data on the high-layer, which adversely affects transfer performance.
