I describe PEDF in the ID. It is a twist on the combination of strict priority
and EDF.
Basically there can be multiple time sensitive flows with different priorities
and non-sensitive traffic as well.
With PEDF one first looks at the TS structure with the highest priority,
however, on

SRv6 Replication SID does not need to follow IPv6 multicast address format
since it is an IPv6 unicast address like any other SRv6 SID.

Some advantages.
If you use budget instead of deadline, you don't need accurate time sync.
If you use budget, the time budget encoded in packet require fewer bits than
using absolute time.
The tightness is related to whether and how many flows can be admitted. It is
related to network resource

The local deadlines are specified in absolute time - not deltas.
So there is no need to add the time saved - it is already there!
As I previously replied, the accuracy of the time sync depends on the tightness
of the budget.
It has nothing to do with the encoding.

Hi Yaakov,
Great work. One suggestion.
If we divide the end-to-end delay budget to per-hop budgets, and carry them in
SR header, we can mimic using the end-to-end absolute deadline. One thing we
need to do is, when the actual time used in a hop is less than the budget of
this hop, you can add t

Bala'zs,
The IEEE definition of TSN mentions determinism, but defines it not as constant
delay as in a TDM service, but rather as
to provide deterministic services through IEEE 802 networks,
i.e., guaranteed packet transport with bounded latency, low packet delay
variation, and low packet loss.
Hi Yaakov,
Thanks for the clarifications, that helps a lot to position correctly your
draft.
As You have wrote: "Determinism is not the main goal of this draft" what
was not clear from the text.
I may be somewhat mis-leaded by the name You have used for the concept.
TSN is widely used in IEEE as
