Hi all, A new revision of draft-zhu-lsr-isis-sr-vtn-flexalgo has been submitted. It describes a Flexible Algorithm based mechanism to build SR based NRPs in some network scenarios.
There are several changes since its last presentation in IETF 114: 1. The background of this work and its relationship with the IETF network slice draft is described. 2. Following the consensus of TEAS WG about terminology alignment between VTN and NRP, the VTNs in this document are now replaced by NRP. 3. The approach to correlate a subset of link resources with a Flex-Algo is elaborated. 4. The targeted scenario and the scalability considerations of the proposed mechanism is described. 5. Editorial changes to improve the readability. As always review and comments are welcome.

Name: draft-zhu-lsr-isis-sr-vtn-flexalgo Revision: 07 Title: Using Flex-Algo for Segment Routing (SR) based Network Resource Partition (NRP) Date: 2024-03-04 Group: Individual Submission Pages: 10 URL: https://www.ietf.org/archive/id/draft-zhu-lsr-isis-sr-vtn-flexalgo-07.txt Status: https://datatracker.ietf.org/doc/draft-zhu-lsr-isis-sr-vtn-flexalgo/ HTMLized: https://datatracker.ietf.org/doc/html/draft-zhu-lsr-isis-sr-vtn-flexalgo Diff: https://author-tools.ietf.org/iddiff?url2=draft-zhu-lsr-isis-sr-vtn-flexalgo-07 Abstract: Enhanced VPNs aim to deliver VPN services with enhanced characteristics, such as guaranteed resources, latency, jitter, etc., so as to support customers requirements for connectivity services with these enhanced characteristics. Enhanced VPN requires integration between the overlay VPN connectivity and the characteristics provided by the underlay network. A Network Resource Partition (NRP) is a subset of the network resources and associated policies on each of a connected set of links in the underlay network. An NRP could be used as the underlay to support one or a group of enhanced VPN services. In some network scenarios, each NRP can be associated with a unique Flexible Algorithm (Flex-Algo), which can provide constraint-path computation based on the customized topological constraints. This document specifies a mechanism to build Segment Routing (SR) based NRPs by combining SR Flex-Algo and IGP L2 bundles with minor extensions.
