This is required to ensure that conex can be incrementally deployed over the Internet. ›R-3: The presence of the marking mechanism should not significantly alter the processing of the packet. This is required to ensure that conex marked packets do not face any undue delays or drops due to a badly chosen mechanism. ›R-4: The markings should be immutable once set by the sender. At the very least, any tampering should be detectable.
