Perhaps his most famous legacy is from RFC 760, which includes a robustness principle often called Postel's law: "an implementation should be conservative in its sending behavior, and liberal in its receiving behavior" (reworded in RFC 1122 as "Be liberal in what you accept, and conservative in what you send").
也许他最著名的贡献是RFC 760，介绍了鲁棒性原则，常被称为Postel法则:“在实现中发送行为应该是保守的，而接受行为应该是开放的”（RFC 1122中改写为“你接受什么是自由的，而你发送什么是保守的”）。
