     ICMPv6 errors for discarding packets due to processing limits
                   draft-herbert-6man-icmp-limits-02

Abstract

   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 node
   that receives such an ICMP error may be able to modify what it sends
   in future packets to avoid subsequent packet discards.

1  Introduction

   This document specifies ICMP errors that can be sent when a node
   discards a packet due to it being unable to process the necessary
   protocol headers because of processing constraints or limits.

   Four of the errors are specific to processing limits of extension
