Have egresses with proper performance. That's the proper operation.
How many core routers would be happy to reassemble at line rates without a forklift upgrade and/or strong administrative tuning?
You don't have to do it with core routers.
End systems are expected and required to reassemble on their own behalf.
That is not a proper operation of tunnels.
Why not?
Lack of transparency.
Even though there is no well defined value of MSL?
MSL is well defined. For TCP, it is defined in RFC793. For IPv4 reassembly, it is defined in RFC1122. For IPv6 reassembly, it is defined in RFC2460.
As you can see, they are different values.
I'm talking about not operation guidance but proper operation.
The tunnel ingress cannot count on administrative tuning on the egress
I'm afraid you don't understand tunnel operation at all.
No amount of proper operation can fix a platform that does not have adequate performance.
Choosing a proper platform is a part of proper operation. Masataka Ohta
