MMS UDP Timing Packet Pair Pre Headers
1 byte
Sequence number 3 bytes
flags = f0 f0 f0 1 byte
ID = 0xff 1 byte
flag = 0x10 2 bytes
Packet Length
Where:
Sequence number starts at 00 and wraps around after 0xff.
3 bytes shown as ‘flags’ is always f0 f0 f0.
ID is always 0xff and is the Packet ID Type for ‘UDP packet pairs’
1 byte shown as ‘flag’ is fixed as 0x10 and is the UDP sequence / TCP flags
value for packet pairs.
Packet Length includes the pre header field length as part of its value
Packet pairs are used in UDP transport protocol timing tests. Two random data
packets are send to the client player so it can time the interval between
them and determine available bandwidth over the network while using UDP.

在这里倾听夜暗的歌声/冥冥中谁奏响沉寂百年的古琴/我又看见夏日里美丽的黄昏/
白天奔忙于生活的人/傍晚就三三两两走到一起：/是南方这样的温暖时常发生

路草长满街道/幸与不幸从不同的着落点退出/他们错过记忆里的某件事/
仿佛一只只岩鹰/方向改变了身体仍在憧憬中/越过一座座灰色的城市
