 In TDS, forwarding a job to another computer does not involve any waiting, because you know (by design) that the other computer will accept the job and try to solve it.This means that latency (the main cause of delays in request-response models) is not an issue, because a computer simply never waits for an answer to come back.The hardware or operating system can guarantee that the message arrives at its destination so the program does not have to worry about anything anymore after it forwards the job.
