Erm,

 

Ok =A8C so =A8C we have waited 6 months for a document =A8C that we w= ill go into SPRING and 6man to discuss =A8C and what we have here in my vie= w =A8C is a document that says precisely nothing.

 

I=A1=AFm going to take this section by section =A8C and I would have = hoped sending an email like this =A8C that it would be a lot longer than it= is going to be =A8C but =A8C since there is so little here =A8C it probably won=A1=AFt be all that long.

 

So let=A1=AFs start at section 3 =A8C

 

Section 3.1.1 is well, just pretty obvious and goes without stating

Section 3.1.2 again, pretty obvious that forwarding efficiency is imp= ortant

Section 3.1.3 again, don=A1=AFt think there is anything much to comme= nt on here =A8C its stating the obvious

 

Then we get to Section 4.

4.1.1 SRv6 Based =A8C I don=A1=AFt believe is within the scope of the= charter =A8C the charter does not say =A8C design a solution =A8C it says = =A8C state the requirements of a solution for compression of segment routing information for use over ipv6.  Nowhere does it sa= y for the design team to decide if that is tied to one protocol or another.

4.1.2 See above comment

4.1.3 No issues

4.1.4 Don=A1=AFt have a major problem with this

4.1.5 Please explain how you would achieve crossing boundaries using = something like a binding SID or something to that effect while being compli= ant with this section

 

Section 5

I have a major issue with explicitly stating you need to support the = behaviors in network programming =A8C that is entirely outside of the chart= er.   Again, the charter states =A8C a solution for compression of segment routing information for use over ipv6.  Th= ere may well be solutions within this that scope that do conform to the beh= aviors of network programming =A8C but there may be solutions where such co= mpression is used for purposes entirely different from those described in network programming =A8C and have no rel= ation to network programming at all. 

 

Now lets look at what else the charter says.

 

The charter states that there would be a comparison of approaches and= methods related to compression =A8C that is not in this document at all = =A8C it is entirely absent. It states that the design team would look into the current solutions and state if they agreed= if there was space for more than one solution or not =A8C and if they were= in agreement =A8C that is entirely missing from this document. 

 

The above points form effectively half the charter.=

 

So =A8C with all this said =A8C I can only conclude based on what is = here =A8C that the design team has failed to date in its mandate =A8C becau= se this document pretty much states the obvious while ignoring the entire second half of the charter.  And this is what we = have waited 6 long months for=A1=AD based on a commitment that the design t= eam would come with a requirements document at IETF 109.  Well =A8C th= is =A8C hardly cuts it as a design document.

 

Disappointed =A8C to say the least

Hi Group,
As you know, the SPRING Working Group set up an SR compression design team = prior to IETF108.
The design team is to produce (rough) consensus (of the DT) outputs to the = WG on two related topics:
1) What are the requirements for solutions to compressing segment routing i= nformation for use over IPv6;
2) A comparison of proposed approaches to compressing segment routing infor= mation for use over IPv6.

With great effort of design team members, DT have finished the version -00 = of the requirements document and have submitted it to datatracker.

Please review it and let's know your comments.

B.R.
