Compressed IPv6 headers must be compliant with [RFC4494], as updated Two mechanisms must be addressed in the context of standard-formed
by [RFC6282], in order to be declared "standard-formed". packets, namely IPv6 over Low-Power Wireless Area Networks (6LowPAN,
[RFC4494]) and Robust Header Compression (ROHC, [RFC3095]). IPv6
over Low-Power Wireless Area Networks (6LowPAN), as defined in
[RFC4494] and updated by [RFC6282] with header compression and
[RFC6775] with neighbor discovery optimizations proposes solutions
for using IPv6 in resource-constrained environments. An adaptation
layer enables the transfer IPv6 packets over networks having a MTU
smaller than the minimum IPv6 MTU. Fragmentation and re-assembly of
IPv6 packets, as well as the resulting state that must be stored in
intermediate nodes, poses substantial challenges to measurements.
Likewise, ROHC operates stateful in compressing headers on subpaths,
storing state in intermediate hosts. The modification of measurement
packets' Type-P by ROHC and 6LowPAN, as well as requirements with
respect to the concept of standard-formed packets for these two
protocols requires substantial work. Because of these reasons we
consider ROHC and 6LowPAN packets to be out of the scope of this
document.
The topic of IPv6 Extension Headers brings current controversies into The topic of IPv6 Extension Headers brings current controversies into
focus as noted by [RFC6564] and [RFC7045]. The following additional focus as noted by [RFC6564] and [RFC7045]. However, measurement use
considerations apply when IPv6 Extension Headers are present: cases in the context of the IPPM framework like in-situ OAM in
enterprise environments or IPv6 Performance and Diagnostic Metrics
(PDM) Destination Option measurements [RFC8250] can benefit from
inspection, modification, addition or deletion of IPv6 extension
headers in hosts along the measurement path.
As a particular use case, hosts on the path may store sending and
intermediate timestamps into dedicated extension headers to support
measurements, monitoring, auditing, or reproducibility in critical
environments. [RFC8250] endorses the use and manipulation of IPv6
extension headers for measurement purposes, consistent with other
approved IETF specifications.
The following additional considerations apply when IPv6 Extension
Headers are present:
o Extension Header inspection: Some intermediate nodes may inspect o Extension Header inspection: Some intermediate nodes may inspect

We further require that if a packet is described as having a "length We further require that if a packet is described as having a "length
of B octets", then 0 <= B <= 65535; and if B is the payload length in of B octets", then 0 <= B <= 65535; and if B is the payload length in
octets, then B <= (65535-IP header size in octets, including any octets, then B <= (65535-IP header size in octets, including any
Extension Headers). The jumbograms defined in [RFC2675] are not Extension Headers). The jumbograms defined in [RFC2675] are not
covered by this length analysis. In practice, the path MTU will covered by this length analysis. In practice, the path MTU will
restrict the length of standard-formed packets that can successfully restrict the length of standard-formed packets that can successfully
traverse the path. traverse the path. Path MTU Discovery (PMTUD, [RFC1191] and
[RFC1981]) or Packetization Layer Path MTU Discovery (PLMTUD,
[RFC4821]) is recommended to prevent fragmentation or ICMP error
messages as a result of IPv6 extension header manipulation.
So, for example, one might imagine defining an IP connectivity metric So, for example, one might imagine defining an IP connectivity metric
as "IP-type-P-connectivity for standard-formed packets with the IP as "IP-type-P-connectivity for standard-formed packets with the IP
Diffserv field set to 0", or, more succinctly, "IP-type- Diffserv field set to 0", or, more succinctly, "IP-type-
P-connectivity with the IP Diffserv Field set to 0", since standard- P-connectivity with the IP Diffserv Field set to 0", since standard-

have a profound affect on packet handling during transit, but does have a profound affect on packet handling during transit, but does

is the "minimal IP packet from A to B" - this is an IP packet with
the following properties:
+ It is standard-formed.
+ Its data payload is 0 octets.
+ It contains no options or Extension Headers.
(Note that we do not define its protocol field, as different values
may lead to different treatment by the network.)
When defining IP metrics we keep in mind that no packet smaller or [RFC2330] defines the "minimal IP packet from A to B" as a particular

network. defining IP metrics no packet smaller or simpler than this can be
transmitted over a correctly operating IP network. However, the
concept of the minimal IP packet has not been used in the meantime
and its practical use is limited. This is why this memo deprecates
the concept of the "minimal IP packet from A to B".
