Patent ID: 7725595

Claim:
A system for embedded communication in a communication network, the system comprising: an embedded transmitter, the embedded transmitter for performing a method comprising: replacing overt data of at least one data field of a packet with embedded data; calculating a first embedded checksum value of the embedded data; comparing the first embedded checksum value to a first overt checksum value; replacing the first overt checksum with a flag value, if the comparison is equal; replacing a first overt checksum value with the first embedded checksum value, if the comparison is unequal; transmitting the packet via the communication network; and an embedded receiver, the embedded receiver for performing a method comprising: receiving the packet; calculating a second embedded checksum value for the embedded data; if the checksum comparison is equal or a flag value is detected: processing the embedded data or forwarding the embedded data to a predetermined embedded data handler; and generating an embedded acknowledgment for the packet, the embedded acknowledgment having an acknowledgment number associated with the packet; else if the checksum comparison is unequal: discarding the current received packet; and repeatedly regenerating an embedded acknowledgment for the last packet successfully received in proper sequence order until a predetermined event occurs.
