The IESG has received a request from the Interface to the Routing System WG (i2rs) to consider the following document: - 'A Data Model for Network Topologies' <draft-ietf-i2rs-yang-network-topo-18.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-12-11. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document defines an abstract (generic) YANG data model for network/service topologies and inventories. The data model serves as a base model which is augmented with technology-specific details in other, more specific topology and inventory data models. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-i2rs-yang-network-topo/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-i2rs-yang-network-topo/ballot/ No IPR declarations have been submitted directly on this I-D.
