Network nodes may discard packets if they are unable to process protocol headers of packets due to processing constraints or limits. When such packets are dropped, the sender receives no indication so it cannot take action to address the cause of discarded packets. This document defines ICMP errors that can be sent by a node that discards packets because it is unable to process the protocol headers. A sender that receives such an ICMP error may be able to modify what it sends in future packets to avoid subsequent packet discards.
