UNI-Augmented Network Topology • Augments the ietf-network model with service -attachment-points module: ietf-uni-topology augment /nw: networks/nw: network/nw: node: +--rw service-attachment-point* [attachmentid] +--rw attachment-id nt: tp-id +--rw type? identityref +--rw admin-status? boolean +--rw oper-status? boolean +--rw encapsulation-type? string • Can be used for a variety of network services 10
Next Steps • Required to cover segments involved in the delivery of a service – Enhances the of view of network controllers – Is not specific to a given service – Complements existing network modules (L 2 NM, L 3 NM) • Consider WG adoption 11
