Packet Transmission

Packet Transmission

The Packet Transmission stores information about packets that are sent from the DockLINK to wireless stations on the network.

Total Packets Transmitted

Total Packets Transmitted counts and stores the total number of packets that the DockLINK sends to wireless stations on the network. The number displayed all transmitted packets.

Average Transmit Rate (Packets/Sec.)

Sometimes packets are transmitted faster than at other times. Average Transmit Rate indicates the average number of packets sent each second. Typical networks range from 100 to 5000 frames transmitted each second, and will vary with time. If you observe the rate staying at 10,000 fps, the local station may be causing a broadcast storm. Broadcast storms can be caused by a defective Network Interface Card.

Total Retransmission

When the distant wireless station does not acknowledge the receipt of a packet sent by DockLINK, DockLINK resends the packet a number of times until the distant station acknowledges receipt of the packet. Total Retransmission counts and stores the number of retransmissions, based upon the total number of packets transmitted.

A higher number in this field may indicate the need to relocate a station’s antenna to improve signal quality.
