In the example below (Figure 7.22) the following events occur in this order:

Host A sends TCP data packet to Viper A.

Viper A transmits packet over the air to Viper B.

Viper B immediately responds with an RF acknowledgment and sends the TCP data

packet to Host B.

Viper A hears an RF acknowledgement from Viper B and generates a TCP ACK to

send to Host A. Host B receives the original TCP data packet and generates a TCP
ACK to send back over the network.

Viper B receives the TCP ACK but does not send it over the air saving bandwidth on
the Airlink

Figure 7.22 TCP Proxy Example

(1) TCP Packet over Ethernet

(2) TCP Packet over Airlink

(3) TCP Packet over Ethernet

Host A

Host B

Viper A

TCP Proxy Enabled

Viper B

TCP Proxy Enabled

(4) When Viper A hears RF ACK it

generates a TCP ACK and sends it

to Host A

(3) RF ACK over Airlink

(5) TCP ACK is not transmitted

(4) Host B generates TCP ACK.
