Re: [Detnet] draft-geng-detnet-requirements-bounded-latency-02 revised for comments

["qiangli (D)" <[e-mail]>]

Hi all,

The Req. 2.2 discusses that DetNet should be able to tolerate a certain degree of clock jitter & wander even within a time synchronous domain. We would like to know if you agree or disagree with this requirement. If you think this requirement is necessary, then to what degree of clock jitter & wander do you expect?

BTW, we are going to ask for WG adoption for this document in IETF 105 meeting. That's will be greatly appreciated if you can share your comments to help us further improve this draft.


Best regards,

Cristina QIANG

Hi all,

This version has collected 7 requirements, and divided these requirements into optional (SHOULD) and mandatory (MUST) two types as following shows. We authors would like to know if this requirement list is complete, and if the classification is appropriate or not.  Your review and comments are highly appropriated.

==========================
Req. 1: Must support the dynamic creation, modification and deletion of deterministic services

Req. 2.1: Should support asynchronous clocks across domains
Req. 2.2 : Should tolerate a certain of clock jitter & wander within a clock synchronous domain

Req. 3: Must support Inter-Continental propagation delay

Req. 4: Should have self-monitoring capability

Req. 5: Should be robust against denial of service attacks

Req. 6: Must tolerate failures of links or nodes and topology changes

Req. 7: Must be scalable
===========================

Best regards,

Cristina QIANG

Dear all,



Since IETF 104, we have carefully revised draft-geng-detnet-requirements-bounded-latency-02 according to received comments. The latest 02 version was uploaded and available online https://datatracker.ietf.org/doc/draft-geng-detnet-requirements-bounded-latency/.



This new version collects more technical, operational and management requirements of deploying deterministic latency service on layer 3 networks from the perspective of various service providers.



Comments are welcome!
