Apply and Close Cancel Broadcast The network clock supports the broadcasting of NTP packets This feature is useful in situation where network administration may wish to avoid the network traffic created by a large number of clients making periodic NTP requests or in situations where such periodic requests end up synchronized is such a manner as to exceed the time servers ability to reply The broadcast mode is a widespread or open ended broadcast not intended for any specific IP address The network clock listens for NTP using the UDP User Datagram Protocol broadcasts using the broadcast address 255 255 255 255 Some firewalls and routers will not forward UDP broadcasts by default Security configurations may need to be adjusted to allow the UDP broadcast packets to pass on the configured port CLKNTD Series User Manual Rev 2 2 4 Page 22 Multicast The network clock also supports multicast addressing of NTP packets As opposed to broadcast mode which is a widespread or open ended broadcast of NTP packets whereby data is sent to every possible client multicasting is useful because it conserves bandwidth It does this by replicating packets only as needed within the network to send them only to clients that want them thereby not transmitting unnecessary packets The concept of a group and group membership is crucial to multicasting Every multicast requires a multicast group the sender transmits to the group addre
