+In addition to the `SUBSCRIBE` / `UNSUBSCRIBE` events sent by the pubsub framework, announcesub must do additional work to maintain the mesh for the topic it is joining or leaving. We will refer to the two topic membership operations below as `JOIN(topic)` and `LEAVE(topic)`.
 
 When the application invokes `JOIN(topic)`, the router will form a topic mesh by selecting up to `D` peers from its [local peering state](#peering-state) first examining the `fanout` map. If there are peers in `fanout[topic]`, the router will move those peers from the `fanout` map to `mesh[topic]`. If the topic is not in the `fanout` map, or if `fanout[topic]` contains fewer than `D` peers, the router will attempt to fill `mesh[topic]` with peers from `peers.announcesub[topic]` which is the set of all announcesub-capable peers it is aware of that are members of the topic.
