    121121UDP packets are variable in length up to a maximum of 1472 bytes (6 bytes of header, 1466 bytes of data). If an Earthworm message has a length less than or equal to 1466 bytes, it will be broadcast in a single UDP packet. If an Earthworm message is longer than 1466 bytes, it will be fragmented by ringtocoax, broadcast in multiple UDP packets, and reassembled by the receiving program (coaxtoring). Ringtocoax will never pack more than one Earthworm message in a single UDP packet.

    123 It is very important that the overall rate of broadcast is as at least as fast as the rate of local information production. For example, if your system produces 256 TYPE_TRACEBUF messages per second (464 bytes each = 1 UDP packet each), then the !BurstCount, !SqrtCount, and !BurstInterval commands should be configured such that ringtocoax will broadcast at least 256 UDP packets per second. System clock resolution must be considered when configuring the three commands, especially BurstInterval. As of April 1999, the time resolution of each sleep on Windows NT is about 16 msec (one clock tick). On Solaris, the resolution is about 10 msec.
