A YANG DATA MODEL FOR ACTN VN OPERATION draft-lee-teas-actn-vn-yang-02 Young Lee, Huawei Dhruv Dhody, Huawei Daniele Ceccarelli, Ericsson Takuya Miyasaka, KDDI Peter Park, KT Bin Yeong Yoon, ETRI

INTRODUCTION • A Yang Data Model for ACTN VN operations • This is for CMI i. e. CNC – MDSC Interface (service Model) • Support for VN views • As set of E 2 E tunnels (VN-Member) • As abstract topology • Support for Access Point (AP) as per the ACTN framework • MDSC translates and maps the VN request into specific network centric-models (e. g. , TE-tunnels [TE-Tunnel], TE-topology [TE-TOPO], etc. ) to coordinate the multi-domain network operations with PNCs. TEAS WG, IETF 97 @ SEOUL 2

UPDATES IN THIS VERSION Support for Pre-Instantiation • VN-compute (stateless) Support for Multi-Source and Multi-Destination • i. e. ability of MDSC to select one of the source / destination among a given set based on current conditions • In case of failure another source / destination could be selected Others • Optional Reference to abstract topology state in [TE-Topology] and tunnel state in [TE-tunnel] • Support for Objective Functions and Metrics as per the [Info-Model]. TEAS WG, IETF 97 @ SEOUL 3

PRE-INSTANTIATION TEAS WG, IETF 97 @ SEOUL • RPC to take input as source, destinations, OF, metric, etc to get an output VN after computation 4

MULTI-SOURCE, MULTI-DESTINATION • Mark a source as a candidate for multisource • Mark a destination as a candidate for multidestination • The selected source and destination as reference to VNmember TEAS WG, IETF 97 @ SEOUL 5

NEXT STEP • Continue to enhance the VN Model to meet all requirements of ACTN • Keep align with all ACTN documents including [Info-Model] • Comments? • Candidate for WG adoption? TEAS WG, IETF 97 @ SEOUL 9
