Handles synchronization logic of NLSR LSDB updates¶

1. Syncing LSDB¶

• NLSR's Syncing Logic Handler (SLH) handles syncing logic of LSDB
• SLH publishes updates on name <router-prefix>
• SLH pushes sequence number to ChronoSync instead of letting ChronoSync generating it for NLSR
• Sequence number is composed from the version number of Adjacency LSA, Prefix LSA and Hyperbolic LSA
• When SLH receives updates notification it decomposes the sequence number and retrieves version for LSAs
• Checks LSAs version with LSDB

• If SLH finds newer version of LSAs, it communicates with InterestManager to send interest for LSAs

• SLH also stores this sequence number in local store and retrieve the last sequence number used when boot up

2. Syncing Certificates¶

• SLH publishes updates on name <certificate-name>
• Sequence number is pushed from SLH
• Upon updates notification reception, checks with certificate store

• If newer version of certificate found, communicates with InterestManager to send interest

• Stores Certificate sequences like LSDB sequences and retrieves when boot up
