5 /* For UDP there is one server instance consisting of udpserverrd and udpserverth
6 * rd is responsible for init and launching wr
7 * For TLS there is a server instance that launches tlsserverrd for each TLS peer
8 * each tlsserverrd launches tlsserverwr
9 * For each UDP/TLS peer there is clientrd and clientwr, clientwr is responsible
10 * for init and launching rd
12 * serverrd will receive a request, processes it and puts it in the requestq of
13 * the appropriate clientwr
14 * clientwr monitors its requestq and sends requests
15 * clientrd looks for responses, processes them and puts them in the replyq of
16 * the peer the request came from
17 * serverwr monitors its reply and sends replies
19 * In addition to the main thread, we have:
20 * If UDP peers are configured, there will be 2 + 2 * #peers UDP threads
21 * If TLS peers are configured, there will initially be 2 * #peers TLS threads
22 * For each TLS peer connecting to us there will be 2 more TLS threads
23 * This is only for connected peers
24 * Example: With 3 UDP peers and 30 TLS peers, there will be a max of
25 * 1 + (2 + 2 * 3) + (2 * 30) + (2 * 30) = 129 threads
29 * May segfault when dtls connections go down? More testing needed
30 * Remove expired stuff from clients request list?
31 * Multiple outgoing connections if not enough IDs? (multiple servers per conf?)
32 * Useful for TCP accounting? Now we require separate server config for alt port
