Dear all

At IETF 111, in the context of draft-geng-spring-sr-redundancy-protection  and well as 2 DetNet drafts, we discussed if we could converge the SRv6 and DetNet signaling for redundancy or keep them completely separate. One of the possibilities to converge is to use the DetNet Redundancy Information Option for PREOF in an SRv6 1+1 use case, and leverage SRv6 to signal the loose sequence of nodes that process the DOH, e.g., DetNet relays.

For instance, the DetNet Redundancy Information Option may be placed in a DOH before an SRH that signals the exhaustive list of the DetNet relays along the path of the packet, so every relay can process the redundancy information therein, while the DetNet Strict Path Option would be placed in an HbH EH to be read by every DetNet forwarding node, and intercepted should it strays away from its path, and possibly omitted for SRv6 1+1.

To enable that, thus new version of the draft adds the capability to place the DetNet options in either HbH or Destination Options headers.

Keep safe;

Pascal

Abstract:
   RFC 8938, the Deterministic Networking Data Plane Framework relies on
   the 6-tuple to identify an IPv6 flow.  But the full DetNet operations
   require also the capabilities to signal meta-information such as a
   sequence within that flow, and to transport different types of
   packets along the same path with the same treatment, e.g.,
   Operations, Administration, and Maintenance packets and/or multiple
   flows with fate and resource sharing.  This document introduces new
   IPv6 options that signal that path and redundancy information to the
   intermediate DetNet relay and forwarding nodes.
