"This dataset shows the Internet has a wide variety of error sources
which can not be detected by link-level checks."
RFC 3819 therefore says:
Packet corruption may be, and is, also caused by bugs in host and
router hardware and software. Even if every subnetwork implemented
strong error detection, it is still essential that end-to-end
checksums are used at the receiving end host [SP2000].
Whether this class of observations is relevant to LoWPANs can be (and
needs to be) discussed.
