+# Gossip Support
+
+The Gossip Support Subsystem is responsible for keeping track of session changes
+and issuing a connection request to all validators in the next, current and
+a few past sessions if we are a validator in these sessions.
+The request will add all validators to a reserved PeerSet, meaning we will not
+reject a connection request from any validator in that set.
+
+In addition to that, it creates a gossip overlay topology per session which
+limits the amount of messages sent and received to be an order of sqrt of the
+validators. Our neighbors in this graph will be forwarded to the network bridge
+with the `NetworkBridgeMessage::NewGossipTopology` message.
+
+See https://github.com/paritytech/polkadot/issues/3239 for more details.
+
+The gossip topology is used by teyrchain distribution subsystems,
+such as Bitfield Distribution, (small) Statement Distribution and
+Approval Distribution to limit the amount of peers we send messages to
+and handle view updates.
