This draft is a work item of the Routing Over Low power and Lossy networks WG of the IETF. Title : Root initiated routing state in RPL Authors : Pascal Thubert Rahul Arvind Jadhav Matthew Gillmore Filename : draft-ietf-roll-dao-projection-17.txt Pages : 51 Date : 2021-06-03 Abstract: This document extends RFC 6550 and RFC 6553 to enable a RPL Root to install and maintain Projected Routes within its DODAG, along a selected set of nodes that may or may not include self, for a chosen duration. This potentially enables routes that are more optimized or resilient than those obtained with the classical distributed operation of RPL, either in terms of the size of a Routing Header or in terms of path length, which impacts both the latency and the packet delivery ratio.

This version answers the open questions below: - Lifetime Unit: could we use a different unit for P-DAO?=20 -> not done yet, do we need this? - How to differentiate a P-DAO from a normal DAO in a local instance?=20 -> new P flag - Make P-DAO bidirectional?=20 -> no, but we could correlate 2 Tracks being exactly reverse in the future - Who sends the PDR? Does it have to be the ingress?=20 -> Yes, and it owns the instance ID namespace - Maintaining the sibling state. Should we have text on using RFC 8505 ther= e?=20 -> done - Whether ingress and egress are listed in NPO? Today they are both, ingres= s to indicate the packet source in case of encapsulation and for SRH-6LoRH = compression reference and egress to build the full SRH-6LoRH. Note that the= ingress must consume the first entry and use it as source.=20 -> all specified, the non storing mode does not indicate the first hop - Error flows, which ICMP errors and to which root? The draft should presen= t the flows.=20 -> could be a WG discussion Ideally at a next interim we could go through the open issues / tickets mak= e sure all is resolved. Keep safe; Pascal -----Original Message----- From: Roll On Behalf Of internet-drafts@ietf.org Sent: jeudi 3 juin 2021 19:14 To: i-d-announce@ietf.org Cc: roll@ietf.org Subject: [Roll] I-D Action: draft-ietf-roll-dao-projection-17.txt A New Internet-Draft is available from the on-line Internet-Drafts director= ies. This draft is a work item of the Routing Over Low power and Lossy networks = WG of the IETF. Title : Root initiated routing state in RPL Authors : Pascal Thubert Rahul Arvind Jadhav Matthew Gillmore Filename : draft-ietf-roll-dao-projection-17.txt Pages : 51 Date : 2021-06-03 Abstract: This document extends RFC 6550 and RFC 6553 to enable a RPL Root to install and maintain Projected Routes within its DODAG, along a selected set of nodes that may or may not include self, for a chosen duration. This potentially enables routes that are more optimized or resilient than those obtained with the classical distributed operation of RPL, either in terms of the size of a Routing Header or in terms of path length, which impacts both the latency and the packet delivery ratio.

Hi Guys,=

 

In the -17 draft fo= r P-DAO, section 3.3, a portion of this section says:

 

A positive PDR-ACK= indicates that the Track was built and that the Roots commits to maintain = the Track for the negotiated lifetime. In the case of a complex Track, each Segment is maintained independently and asyn= chronously by the Root, with its own lifetime that may be shorter, the same= , or longer than that of the Track. The Root may use an asynchronous PDR-AC= K with an negative status to indicate that the Track was terminated before its time.

 

 

I think it will be = very difficult for the root to maintain tracks, given the spurious nature o= f topology changes in an RF mesh --- Rather than a PDR-ACK that says the tr= ack could not be maintained, could we have something like an async notification that says, =93Your previous trac= k is stale, here=92s the new version=94  as long as the egress point s= till exists.  Assuming it=92s possible that the egress joined another = DODAG.

 

I haven=92t read th= e entire draft yet so I may have missed something that would preclude this = capability.

 

Thanks,<= /span>

Hello Randy

 

Not sure what you mean by “Your previous track is stale, hereR= 17;s the new version”. As it goes, the Root can redraw the Track, add segments here,  remove= others there, it’s still the same track as long as it is functional,= and there’s no provision in the draft to tell the ingress about thos= e changes.

 

If that does not help, could you please rephrase?=

Hi Guys,

 

In the -17 draft for P-DAO, section 3.3, a portion of this s= ection says:

 

A positive PDR-ACK indicates that the Track was bu= ilt and that the Roots commits to maintain the Track for the negotiated lifetime. In the case of a complex Track, each Segment = is maintained independently and asynchronously by the Root, with its own li= fetime that may be shorter, the same, or longer than that of the Track. The= Root may use an asynchronous PDR-ACK with an negative status to indicate that the Track was terminated before i= ts time.

 

 

I think it will be very difficult for the root to maintain t= racks, given the spurious nature of topology changes in an RF mesh --- Rath= er than a PDR-ACK that says the track could not be maintained, could we have something like an async notification that= says, “Your previous track is stale, here’s the new version= 221;  as long as the egress point still exists.  Assuming it̵= 7;s possible that the egress joined another DODAG.=

 

I haven’t read the entire draft yet so I may have miss= ed something that would preclude this capability.

 

Thanks,

Randy

node(A) would like = to setup P2P communications with node (B), so it issues a P-DAO request to = the root/PCE for  a path from (A) to (B).  If this request is suc= cessful, the PDR-ACK returns a set of VIAs from (A) to (B).

 

So (A) can source-r= oute a packet from itself to (B) based on the VIA information.

 

The root will monit= or any change to the projected route, and if the route cannot be maintained= , it will asynchronously notify (A).

 

If this interpretat= ion is correct, then I was thinking that, if the state of the projected rou= te changes (through future DAO/SIO reception by the root), then a new proje= cted route could be calculated and node(A) could be asynchronously notified of new VIAs for its=92 originally request= ed route to (B), without receiving an async notification that the route is = no longer valid, and having to possibly perform a new P-DAO request.

Hi Guys,

 <= /o:p>

In the -17 draft fo= r P-DAO, section 3.3, a portion of this section says:

 <= /o:p>

A positive PDR-ACK= indicates that the Track was built and that the Roots commits to maintain = the Track for the negotiated lifetime. In the case of a complex Track, each Segment is maintained independently and asyn= chronously by the Root, with its own lifetime that may be shorter, the same= , or longer than that of the Track. The Root may use an asynchronous PDR-AC= K with an negative status to indicate that the Track was terminated before its time.

 <= /o:p>

 <= /o:p>

I think it will be = very difficult for the root to maintain tracks, given the spurious nature o= f topology changes in an RF mesh --- Rather than a PDR-ACK that says the tr= ack could not be maintained, could we have something like an async notification that says, =93Your previous trac= k is stale, here=92s the new version=94  as long as the egress point s= till exists.  Assuming it=92s possible that the egress joined another = DODAG.

multicast DIS/DIO operation, this implies that if the DIO trickle timer is already at Imin and if the node hears a multicast DIS, then the timer does nothing. It MUST NOT reset the timer again in this case.=E2=80=9D The first paragraph at first seemed redundant with the Trickle = specification: if it is already at Imin, it does nothing, which means it = does not reset the timer. Or is the ambiguity about resetting the timer? = If so, then I think this refinement is correct. External events should = be able to be considered inconsistencies, not hard-reset the timer. In = retrospect, the sentence=20 Trickle can also reset its timer in response to external =E2=80=9Cevents= " Perhaps could have been External events can also cause Trickle to act as if it has detected an = inconsistency. So I think this paragraph makes sense, but the way to characterize it is = that a multicast DIS resets the timer only if I > Imin. The next paragraph I=E2=80=99m a little more confused about: =20 "An implementation MUST never restart the timer within an interval. For e.g., in the above figure, if the timer is in interval I2, the implementation MUST never restart the timer to the beginning of the current interval i.e., I2. If the timer is in interval T2 and if the reset is to be done then the interval is set back to Imin. If the timer is already in Imin, then the reset should do nothing.=E2=80=9D Trickle never =E2=80=9Crestarts=E2=80=9D a timer. It can reset a timer = to Imin, but not restart the timer within a particular interval. Under = what circumstances would an implementation =E2=80=9Crestart=E2=80=9D a = timer to the beginning of the current interval?=20 Phil > On Jun 3, 2021, at 5:32 AM, internet-drafts@ietf.org wrote:

Hi all,

I would like to ask about two possibilities regarding the dao-pro= jection draft that most probably&nb= sp;have been discussed before.
1- According to the draft, the projected routes are only installed with hig= hest probability. What if the controller aims at installing backup routes/a= ny other priority?
2- Can the root node use projected DAO to install multiple parents/multipat= h routing?

Hello Iliard;

 

I hope you’re doing good.

 

  1. Th= e problem when you have multiple topologies (like the main DODAG and the Tr= ack) is that switching the packet from one topology to another may yield loops. This can be addressed by forcing an o= rder relationship, like a DODAG of topologies, or a distance. One can jump = on another topology if that topology is “lower” but never highe= r. The current design is that the Track is lower than the main DODAG so once you jump in a Track, you can never return to t= he main dodag, the track must take you to destination, or you switch to a l= ower Track. If the track was higher the packet swould immediately leave the= Track to follow the main DODAG and never return.

 

We have not really formalized that “rank”= of Tracks. Maybe we should

Hi al= l,

I would like to ask about two possibilities regarding the dao-pro= jection draft that most probably have been discussed before.

1- Ac= cording to the draft, the projected routes are only installed with highest = probability. What if the controller aims at installing backup routes/any other priority?

2- Ca= n the root node use projected DAO to install multiple parents/multipath rou= ting?

Remember that there is still quite some potential for changes. The IoT-relevant conflicts that most meet the eye this time are LAKE/RATS, IOTOPS/RATS (and there is likely to be an IoT-relevant discussion at tsvwg, which overlaps the third RATS). All times *on my agenda* are in UTC (the default page is UTC-0700). Please forgive the 2500, I'm way too lazy to write code to turn this into 0100. (And it is advisable to ignore the fictional end time of the Wednesday plenary anyway.) https://datatracker.ietf.org/meeting/agenda-utc might be handy.
