I am learning how the Tezos peer-to-peer network works. I understood the basic design where the maintenance worker will keep connecting to the known points from p2p_pool. According to the documentation, when there are not enough points in the pool, the peer discovery worker will be triggered.
How does this help? What does this peer discovery do? Isn't that it only advertises the identities of our nodes to our peers?
Additional to this, can someone please enlighten me on how a point (IP + port) is considered as a known point?
