Should the =93No Next-Header=94 (next-header=3D59) be included (cfr my othe= r remarks on the companion I-D) ? There should be a way to convey the information that the exporter was (un)a= ble to parse the *full* extension header chain due to HW limitation. This c= ould be done by adding a bit/counter =93KNOWN=94 (the opposite of UNKNOWN i= n the sense of a known layer-4 header).

Beno=EEt and Med,

 

Thanks for this useful document= , please find below some comments (obviously without any hat).

 

Should the =93No Next-Header=94= (next-header=3D59) be included (cfr my other remarks on the companion I-D)= ?

 

There should be a way to convey= the information that the exporter was (un)able to parse the *full* = extension header chain due to HW limitation. This could be done by adding a= bit/counter =93KNOWN=94 (the opposite of UNKNOWN in the sense of a known layer-4 header).

 

About having counters per exten= sion header how is =93This Information Element echoes the order and number = of occurrences=94 to be interpreted for the following flow?

 

HBH-RH-DST

HBH-DST-RH-FRA0-DST<= /span>

HBH-DST-RH-FRA1-...<= /span>

RH-DST

 

Will it be a single IE with HBH= =3D3, DST=3D5, RH=3D3, FRA0=3D1, FRA1=3D1 or 4 IE exported (one for each ch= ain) ?

 

I think that the 4 IE sounds mo= re logical and useful, then there is no need to count the occurrences of on= e specific EH but more how often a specific EH chain was seen.

 

I still wonder why the tcpOptio= ns and ipv6ExtensionHeaders are in the same I-D though ;-)

 

Hope this helps,
