2. BGP-LS Code BGP-LS = BGP + draft-ietf-idr-ls-distribution-03 Code:
implementation of a BGP protocol library, supporting BGP-4, Graceful Restart, Multiprotocol extensions, BGP/LS, Communities, Extended Communities and 4-Byte AS numbers (NEW speaker only)
implementation of BGP message parser
implementation of a BGP RIB, allowing for redundant data sources, but limited to listener-only functionality

3. BGP-LS Models BGP-LS-NLRI.yang
Model representation of BGP-LS NLRI as defined in draft-ietf-idr-ls- distribution-03
Each NLRI is a notification
Defines BGP-LS concepts
Remains to be finalized
ISIS/OSPF/L3.. .yang
Model representations of BGP topology in various routing protocols
Supports multiple topologies
Provided by draft-clemm-yang-network-topo-00
Intent to integrate with MDA

4. BGP-LS code next steps Switch current code to use Netty 4.0
Switch to using model-driven SAL
Use MD-SAL infrastructure to generate DTOs based on models
Modify BGP parser to instantiate DTOs and trigger MD-SAL notifications
Modify RIB implementation to subscribe to MD-SAL notification feed

6. PCEP Code
implementation of a PCEP protocol library, supporting PCEP, Objective functions, Diffserv, Stateful extensions, GCO and PCE- initiated LSPs
implementation of PCEP message parser
RFC5440 – PCEP
RFC5541 – Objective Functions in PCEP
RFC5455 – Diffserv-Aware Class-Type Object
draft-ietf-pce-stateful-pce-05
draft-crabbe-pce-stateful-pce-mpls-te-01

RFC5557 – Global Concurrent Optimization (GCO)

7. PCEP Models PCEP message.yang
model representations of all PCEP messages
each message is a notification
defines PCEP concepts
remains to be written
PCEP tunnel.yang
model representation of an end-to-end PCEP tunnel
Overlaid over an IGP topology
Remains to be written

8. PCEP code next steps Switch current code to use Netty 4.0
Cleanup / refactor current code for better clarity
Switch to using model-driven SAL
Use MD-SAL infrastructure to generate DTOs based on models
Modify PCEP parser to instantiate DTOs and trigger MD-SAL notifications
Transform MD-SAL notifications to/from PCEP Tunnel DTOs
Serialize MD-SAL notifications to PCEP messages
