Hi Jeff,

 

Thanks for the comments.

The Source Packet Routing in NetworkinG (SPRING) Working Group is the home of

Segment Routing (SR) using MPLS (SR-MPLS) and IPv6 (SRv6).

[jeff] I’d add “dataplanes”

 

robjs> I don't think that SPRING should limit itself to having to just work on dataplane technologies. The functional specifications or architectures that are proposed are likely to span both data, control, and management planes (e.g., YANG models, counter specifications). I'd be interested if you disagree?

[jeff] I absolutely agree with you that the work should have all abovementioned planes, it is more to how the sentence reads, I meant not to limit the works to dataplane only but a common convention, when we say SR-MPLS we really mean SR with MPLS data plane, same for SRv6

o Using SR

[jeff] SR conveyed metadata perhaps? Think of BSID x-connect into another layer

 

robjs> I'd argue that this is more than metadata, it's really a forwarding instruction that says to send to some other layer, or that is interpreted in another domain. Metadata to me would mean information that we're carrying on the packet that *isn't* used for forwarding.

[jeff] we’d disagree on this one, I would not consider setting the context (ie where to lookup) as a forwarding instruction

     * lsr on OSPF and IS-IS extensions to flood SPRING-related information

[jeff] in RIFT we plan to support SR as well

 

robjs> This is probably RIFT co-ordinating with SPRING. I'd rather avoid listing another protocol here without there being SPRING work that affects it. Of course, please do involve SPRING in discussions of SR support in RIFT.

[jeff] Ack

     * teas on generic traffic engineering architecture

[jeff] rtgwg for fast convergence related topics

 

robjs> Thanks -- yes, given all the work in rtgwg on this topic, this should definitely be added.

[jeff] thanks!

 

Thanks,
