18 /* For UDP there is one server instance consisting of udpserverrd and udpserverth
19 * rd is responsible for init and launching wr
20 * For TLS there is a server instance that launches tlsserverrd for each TLS peer
21 * each tlsserverrd launches tlsserverwr
22 * For each UDP/TLS peer there is clientrd and clientwr, clientwr is responsible
23 * for init and launching rd
25 * serverrd will receive a request, processes it and puts it in the requestq of
26 * the appropriate clientwr
27 * clientwr monitors its requestq and sends requests
28 * clientrd looks for responses, processes them and puts them in the replyq of
29 * the peer the request came from
30 * serverwr monitors its reply and sends replies
32 * In addition to the main thread, we have:
33 * If UDP peers are configured, there will be 2 + 2 * #peers UDP threads
34 * If TLS peers are configured, there will initially be 2 * #peers TLS threads
35 * For each TLS peer connecting to us there will be 2 more TLS threads
36 * This is only for connected peers
37 * Example: With 3 UDP peers and 30 TLS peers, there will be a max of
38 * 1 + (2 + 2 * 3) + (2 * 30) + (2 * 30) = 129 threads
42 * May segfault when dtls connections go down? More testing needed
43 * Remove expired stuff from clients request list?
44 * Multiple outgoing connections if not enough IDs? (multiple servers per conf?)
45 * Useful for TCP accounting? Now we require separate server config for alt port
