TTL定义于IPv4协议中,如下 ip protocol RFC规定占8位,即数值0-255。 TTL,其实就是记录了网络的路径跳数 。 The Time-to-Live field, or TTL, sets an upper limit on the number of routers through which a datagram can pass. It is initialized by the sender to some value (64 is recommended [RFC...
都需要将TTL减1，也就是说TTL等于IP数据包能经历的最大跳（hop）数，而不是时间（秒数）。所以，为...
How to hide textField in report generated in specified format? I am using the JasperReports 4.7, Trying to hide a text field while exporting to pdf,xsl. I've tried the using of net.sf.jasperreports.export.{format}.exclude.origin.{suffix}.{arbitrary_name} property... ...
What IPv6 Field Is Similar to the TTL Field in IPv4 Packets? IPv6 and IPv4are different kinds of IPs. They both route packets of data through a series of rules (or protocols). These IPs contain information that enables data to arrive at its intended destination. IP headers contain the in...

zero, then the datagram must be destroyed. This field is modified in internet header processing. The time is measured in units of seconds, but since every module that processes a datagram must decrease the TTL by at least one even if it process the datagram in ...
The IPFIX Information Element 192 value corresponds to the Time to Live (TTL) field in the IPv4 packet header. The TTL field is 8 bits long, giving us a maximum value of 255. For IPv6, the value of the information element matches the value of the Hop Limit field in the IPv6 packet...
估计是以最早的定义来做对比，TTL的确是 Time To Live 的简写，我估计一开始规划IPv4报文的时候没想到...
This is used to modify the IPv4 TTL header field. The TTL field determines how many hops (routers) a packet can traverse until it’s time to live is exceeded. Setting or incrementing the TTL field can potentially be very dangerous, so it should be avoided at any cost. ...
In IPv6 this is called the hop limit, and in IPv4 it is called TTL. The Hop field is the same as the TTL field in IPv4. The hop counting function is necessary for the network to function. This prevents network failure due to packets looping indefinitely. Transport prot...
