Dear Authors & Contributors of draft-ietf-spring-resource-aware-segments,
I have few questions in respect to your proposal:
#1 - If you say that DiffServ mechanism is not sufficient to handle data
plane processing across the nodes are you envisioning that new forwarding
hardware will be needed (or upgrade to the existing one if programmable) to
take into forwarding decision resource aware SIDs ?
#2 - As you know SR is not required at non SR capable nodes and SR segment
can often span multiple nodes. How are you going to protect your resources
in non SR transit nodes ?
#3 - Document says that signalling resource aware SIDs and resources
associated with it is out of scope, how are you planning to propagate
resource utilization at least between segment nodes and controller (PCE) ?
Many thx,
Robert

Abstract:
This document describes the mechanism to associate network resources
to Segment Routing Identifiers (SIDs). Such SIDs are referred to as
resource-aware SIDs in this document. The resource-aware SIDs retain
their original forwarding semantics, but with the additional
semantics to identify the set of network resources available for the
packet processing and forwarding action. The resource-aware SIDs can
therefore be used to build SR paths or virtual networks with a set of
reserved network resources. The proposed mechanism is applicable to
both segment routing with MPLS data plane (SR-MPLS) and segment
routing with IPv6 data plane (SRv6).
