Example Store & Forward Table
Note 1 – The link layer of Node 1 blocks the re-transmission of a packet that is received with the SRC byte equal to the
receiving node’s station address. Packets received that originate from the receiving node should never be re-transmitted.
Note 2 – To prevent Node 2 from re-transmitting a duplicate packet, the link layer of Node 2 updates the duplicate packet
table with the last 20 packets received.
Note 3 – The link layer of Node 4 blocks the re-transmission of a packet that is received with the SRC byte equal to the
receiving node’s station address. Packets received that originate from the receiving node should never be re-transmitted.
Note 4 – To prevent Node 3 from re-transmitting a duplicate packet, the link layer of Node 3 updates the duplicate packet
table with the last 20 packets received.
