Guaranteed qos includes three basic parameters : packet transfer delay , packet delay variation and packet loss rate 有保证的服务品质包含三种参数：封包传输延迟、封包延迟变异，以及封包遗失率。
Decryption generates the identical keystream used for encryption using the transmitted - with - the - packet iv and the shared secret key 解密通过使用带信息包传输的iv和共享密钥来生成用于加密的等同密钥流。
In both instances , this might cause an increase in the frequency of dropped packets resulting in significant interruption thresholds 在上面两种情况中，有限带宽可能会引起数据包传输中断更加频繁，从而导致重大的中断阀值。
Packet transfer unit ( pte ) is one of the most important units of np , which is responsible for packet analyzing and processing 包传输(或包转换)单元( packettransferunit ， pte )是网络处理器中负责ip包协议处理的核心模块，完成ip包在转发过程中的分析处理。
Protecting embedded ethernet packet transport services from interruption within carrierclass environments requires a complete end - to - end ip transparent solution 在电信环境中,为使分组包传输服务不致于因为故障而中断,需要一个完整的端-端ip无关的解决方案。
When we say “ best route ” we consider parameters like the number of hops ( the trip a packet takes from one router or intermediate point to another in the network ) , time delay and communication cost of packet transmission 我们所说的最优路径需要考虑到的参数包括最优路由路径（信息包从在网络中一个路由器或中间节点传输到另一个路由器或中间节点）的数量，延迟时间和信息包传输过程中的消耗等等。
In july 1998 , the ieee standardization group selected the ofdm modulation technique for their new ieee802 . 1 la standard , targeting data transmission from 6 up to 54 mbps . meanwhile , this new ieee standard is the first one to use ofdm in packet based communications 同时该标准是第一个将ofdm技术应用于包传输通信中的ieee标准(在该标准提出以前， ofdm通常局限使用于连续传输系统中，如： dvb ， hdtv ) 。
We also can expect more and more communication systems will support ip packet transmission , which means more and more communication systems including beyond 3g mobile communication systems will have the characteristic of the " burst mode " 突发模式的传输已经广泛的应用于各类多接入的上行系统中。并且，可以预料的是：随着通信系统向基于ipv6核心网的全ip包传输方向的发展，越来越多的通信系统将具有“突发模式”的特征。
With switched control system theory and robust stability theory , the sufficient conditions for the asymptotic stability criterion of ncs with multi - packet transmission are obtained , and the method to design a periodically dynamic output feedback stabilization controller is firstly put forward in this paper 利用切换系统理论和鲁棒稳定性理论，得到多包传输网络控制系统的渐近稳定性判据，并首次提出周期动态输出反馈镇定控制器的设计方法。
This positional inaccuracy may be lowered by introducing additional information in the update message : for example a timestamp stating from which point the speed change was done will make the replicated path finally rejoin the original one , although the temporary phase during when the update message is transitting will have a different path 这种位置上的偏差可以通过在更新包中引入额外信息来降低：比如一个表示速度从什么时候开始改变的时间戳可以使得复制体的移动路径最终与实际路径合并上，虽然在更新包传输的过程中，复制体还是会产生一个不大一样的路径。
