The symmetric active end sends a synchronization request packet to the symmetric passive
end with the mode field being set to 1. The value 1 indicates the symmetric active mode.
Upon receiving the request packet, the symmetric passive end automatically works in
symmetric passive mode and sends a response packet with the mode field being set to 2.
The value 2 indicates the symmetric passive mode.
The server periodically sends clock synchronization packets to the broadcast address
255.255.255.255.
The client senses broadcast packets from the server.
After receiving the first broadcast packet, to estimate the network delay, the client enables
a temporary Client/Server model for exchanging messages with the remote server.
The client then works in broadcast client mode, and continues to sense the incoming
broadcast packets to synchronize the local clock.
The server periodically sends clock synchronization packets to the configured multicast
address. By default, the multicast address is 224.0.1.1.
The client senses multicast packets from the server.
After receiving the first multicast packet, to estimate the network delay, the client enables
a temporary Client/Server model for exchanging messages with the remote server.
The client works in multicast client mode, and continues to sense the incoming multicast
packets to synchronize the local clock.
The manycast client periodically sends clock synchronization packets manycast server with
specified multicast address. By default, the multicast address is 224.0.1.1.
The manycast server senses manycast packets from the manycast client and responds to
the client with unicast packet.
After receiving the first unicast packet by manycast client, to estimate the network delay,
the client creates an ephemeral association with the server for exchanging unicast packets.
The server works in manycast server mode, and continues to sense the incoming manycast
packets.
