The Herder subsystem in Stellar Core drives the consensus protocol by managing agreement among nodes. It coordinates voting and externalization processes to ensure validators agree on the next ledger before committing transactions.

The Herder subsystem's role in Stellar Core ledger externalization is to finalize consensus values and close the current ledger. It transitions agreed-upon transaction sets into immutable ledger entries for the network.

Stellar Core handles transaction management within the Herder subsystem by queuing, validating, and forwarding transactions. The Herder ensures only valid transactions are proposed during consensus and subsequently applied to the ledger.

Key classes and data structures in the Stellar Core Herder architecture include components for tracking slots, managing ballots, and storing pending transactions. These structures map the control flows for consensus and ledger closing.
