The Stellar Core overlay network manages peer-to-peer connections through the OverlayManager and Peer classes, which handle handshake processes, connection establishment, and message flooding across the network.

The FlowControl class regulates network traffic within the Stellar Core overlay subsystem, preventing peer-to-peer message flooding from overwhelming nodes by managing data transmission rates during network operations.

Stellar nodes fetch missing data across the peer-to-peer network using the ItemFetcher component, which retrieves specific transactions or data items that were not received during the initial message flooding process.

Transaction flooding in the Stellar Core network architecture works through the Floodgate component, which broadcasts received transactions to all connected peers, ensuring data propagates rapidly throughout the peer-to-peer network.

Yes, you can use this summary to understand the TCPPeer handshake process in Stellar, as it details how TCPPeer establishes connections and authenticates with other nodes before exchanging overlay network messages.
