-- Second Life のUDPパケットでは Big Endianと Little Endian が混在している．要注意． +
-- 以下，特に断らない場合は1Byte = 8bit = 1octet として記述 （一般的には 1Byte=8bit とは限らない） +

-- ''KK'' パケット種別．以下のオクテットの論理和 (1octet) +
- #define MSG_APPENDED_ACKS 0x10 +

- #define MSG_ZEROCODED 0x80 +
--- [[MSG_APPENDED_ACKS>Second Life/Protocol/UDP/MSG_APPENDED_ACKS]]： ボディの最後にACKデータが追加されている． +
--- MSG_RESENT： 再送パケット +
--- MSG_RELIABLE： ACKの返答を要求するパケット +
--- MSG_ZEROCODED： ボディ部は 0x00 の連長圧縮で圧縮されている +

-- ''ZZ ZZ ZZ ZZ''  1から始まるパケットのシーケンス番号（パケット番号） (4octet) ''Big Endien'' +
-- ''HH''  エクストラ（拡張）ヘッダの長さ(オクテット単位） (1octet) +
-- ''[MM MM ....]''  エクストラ（拡張）ヘッダ (長さは ''HH'' に依存) +
-- ''LL [LL LL LL]''  プロトコル番号（ボディの種別） +
