Dear all, This new revision of draft-ietf-spring-sr-for-enhanced-vpn is to address the comments received during the SPRING interim meeting. As suggested by the WG chairs, a new section on operational considerations has been added. There are also several editorial changes to improve the readability of this document. The authors believe this document is ready for WG last call.
As always, review and comments are welcome. Best regards, Jie (on behalf of coauthors) -----Original Message----- From: [email protected] <[email protected]> Sent: Monday, December 15, 2025 5:09 PM To: [email protected] Cc: [email protected] Subject: [spring] I-D Action: draft-ietf-spring-sr-for-enhanced-vpn-10.txt Internet-Draft draft-ietf-spring-sr-for-enhanced-vpn-10.txt is now available. It is a work item of the Source Packet Routing in Networking (SPRING) WG of the IETF. Title: Segment Routing based Network Resource Partition (NRP) for Enhanced VPN Authors: Jie Dong Takuya Miyasaka Yongqing Zhu Fengwei Qin Zhenqiang Li Name: draft-ietf-spring-sr-for-enhanced-vpn-10.txt Pages: 20 Dates: 2025-12-15 Abstract: Enhanced VPNs aim to deliver VPN services with enhanced characteristics, such as guaranteed resources, latency, jitter, etc., so as to support customers requirements on 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. Segment Routing (SR) leverages the source routing paradigm. A node steers a packet through an ordered list of instructions, called "segments". A segment is referred to by its Segment Identifier (SID). SIDs can represent topological or service based instructions. SIDs can further be associated with a set of network resources used for executing the instruction. Such SIDs are called resource-aware SIDs. A group of resource-aware SIDs may be used to build SR based NRPs, which provide customized network topology and resource attributes required by one or a group of enhanced VPN services. This document describes an approach to build SR based NRPs using resource-aware SIDs. The SR based NRP can be used to deliver enhanced VPN services in SR networks.
