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

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

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

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

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

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
