5. Created by Jan Medved www.opendaylight.org  ~110 models defined in OpenDaylight  https://wiki.opendaylight.org/view/OpenDaylight_Controller:MD- SAL:Model_Reference https://wiki.opendaylight.org/view/OpenDaylight_Controller:MD- SAL:Model_Reference  3 models from RFCs  RFC6021  RFC6022  8 models from current drafts  draft-clemm-i2rs-yang-network-topo  draft-ietf-netmod-iana-afn-safi  draft-ietf-netmod-iana-if-type  ~10 models dealing with IETF protocols (BGP, PCEP)  ~27 models dealing with OpenFlow (1.0, 1.3)  ~35 internal wiring models  ~15 conceptual prototypes What Models 5

6. Created by Jan Medved www.opendaylight.org  Represents manageable endpoints connected to controller  Simple base model, only skeleton concepts  Node – manageable endpoint, logical node  Node Connector – connection point present on logical node (interface, port, etc.)  Extended by technology-specific models  Flow-capable Node for OpenFlow 1.3  Capabilities  Flow tables  NETCONF Node  Capabilities  Pass-through access to the underlying device Inventory model 6

7. Created by Jan Medved www.opendaylight.org  Message-level model of PCEP  Based in part on draft-cmfg-pce-pcep-grammar  RFC5440, RFC5441, RFC5455, RFC5521, RFC5557  draft-ietf-pce-stateful-pce augmentation-{02,07}  draft-{crabbe,ietf}-pce-pce-initiated-lsp-00 augmentation  Message is a Notification  Augmentation of topology model with list of reported LSPs  RPC model for invoking PCInitiate/PCUpd requests  Tool-generated DTOs, extensible parser  https://wiki.opendaylight.org/view/BGP_LS_PCEP:Models https://wiki.opendaylight.org/view/BGP_LS_PCEP:Models PCEP protocol model 7
