And that, particularly if the specialised service uses IP, is the problem?

And end-to-end means to a particular device or, more probably, an end
network controlled by the service supplier.

I stopped liking "end-to-end" sometime back.

I have no idea what and how to implement technically what they talk
about as "specialices service that does not impcat...".

In a packet based network, if the outgoing interface is not full, all
packets will be forwarded as soon as possible.

If the outgoing interface is full, then one can either queue all packets
equally (M/M/1 queuing theory) or one can have multiple queues (M/M/N).
If one have a specialized service that have some special treatment, then
by definition that implies longer delay on other queues (as packets get
reordered).

Now, there are some special cases as well where the _services_ sold can
be different (i.e. some business connection with some SLA that is higher
than some SLA for end users paying less).

What I think is sad is that they did not stop at saying for example:

- Each provider of a service is required to always deliver to their
customers the service they have promised to deliver. (Regardless of what
other services they deliver to other customers on the same network...)

Not any silly end-to-end. No silly "specialized service" etc.

Then in other paragraphs they already (if I remember correctly) have
wording about equal treatment, dominant provider of services etc.
