Purpose
Data
model for
n
etwork
t
opologies
Generic topology model, extensions for specific topologies
L3
Unicast
IGP
,
OSPF
, IS-IS as part of this draft
Can be extended for other topologies
Specified using
YANG
Applications
Data nodes capture and reconcile their understanding of network topology, propagate topology info
Network controllers represent controller network topology Slide3
AdoptionImplementation shipping in
OpenDaylight
since February
Export of topology gleaned from BGP/LS
Export of LERs attached via
PCEP
ODL-private extension for PCEP
Proposed to become one of the core ODL modelsSlide4
Next stepsRe-issue the draft
Split the L3-specific models into separate draft
Do we need a separate information model?Slide5
Model structure
Topology
Node
Link
Termination Point
Links connect nodes, are terminated by termination points
Topologies can refer to underlay topologies
Links can refer to underlay links
Nodes can refer to underlay nodes
Unidirectional, point-to-point links
represent non-
ptp
through hierarchies of nodes linksSlide6

Generic topology model
Traffic engineering data definitions, used in multiple topologies
Model allows for multiple levels of refinement
Additional topologies can be added at any refinement levelSlide7
