属性中的所有字段(Tyep、Length/Value)都首先发送最高有效位,即大端字节序。 在填充之前,Length字段表示以字节为单位的Value字段的长度。因为STUN Message在32位边界上对齐属性,即要求STUN Message的总长度是4字节的倍数,因此如果属性的Value字段长度不是4个字节的倍数,则将用1个,2个或3个字节
个以上的SP或HT开头就行。 HTTP-header = field-name ":" [ field-value ] CRLF field-name = token field-value = *( field-content | LWS ) field-content = <the OCTETs making up the field-value and consisting of either *TEXT or combinations of token, tspecials, and quoted-string> 标题域...

The first byte of the control code will be all ones, the escape character. The second byte will have the low order bit on and zeros elsewhere for EOR and the second low order bit on for EOF; that is, the byte will have value 1 for EOR and value 2 for EOF. EOR and EOF may be...

MD5算法即 MD5信息摘要算法,可以产生出一个128位(16字节)的散列值(hash value),用于确保信息传输完整一致。这套算法的程序在 RFC 1321 标准中被加以规范。1996年后该算法被证实存在弱点,可以被加以破解,对于需要高度安全性的数据,专家一般建议改用其他算法,如SHA-2。2004年,证实MD5算法无法防止碰撞(collision),...

采取KEY/VALUE 分块存储方式,因为 KEY 限定为数字类型,只需内存计算便可算出 KEY 的位置,KEY 中存放了 VALUE 的位置,所以对于任何的数据查询只需两次磁盘定位。(本人在和讯做流量统计存储时,使用该种方式替代了BSD、TC 等采用B树的 K-V 存储)。1.2.12、其它功能库...
