sntp时候办事器是指操纵一种简略的收集时候和谈停止时候同步的。sntp收集和谈是由NTP收集时候和谈改编而来的,NTP收集时候和谈它是同步计较机的和谈。以是在授时方面sntp时候办事器也能够或许到达NTP时候办事器一样的功效。

sntp时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)办事器(qi)以卫星(xing)时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)旌旗(qi)灯号为(wei)时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)基(ji)准,并输入UTC国(guo)际规范时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)信息。sntp时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)办事器(qi)能够或许从原子钟、地理台、卫星(xing)、Internet等(deng)时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)参考物上取得UTC的(de)(de)(de)时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou),sntp时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)办事器(qi)将UTC全国(guo)调和时(shi)(shi)(shi)(shi)同步于计较机,因为(wei)时(shi)(shi)(shi)(shi)区(qu)差别咱们所(suo)操纵的(de)(de)(de)北京时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)为(wei)UTC+8小时(shi)(shi)(shi)(shi)。sntp时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)办事器(qi)有(you)了切确的(de)(de)(de)时(shi)(shi)(shi)(shi)候(hou)(hou)(hou)(hou)源,以是(shi)它的(de)(de)(de)授时(shi)(shi)(shi)(shi)精度也有(you)所(suo)进步为(wei)毫秒级(ji)。




sntp时(shi)候(hou)办(ban)事器(qi)能够或(huo)许操纵单播(bo)(bo)(bo)或(huo)播(bo)(bo)(bo)送(song)形式(shi)操纵。单播(bo)(bo)(bo)形式(shi)是终端装(zhuang)备(bei)(bei)经(jing)由过程按期拜候(hou)sntp时(shi)候(hou)办(ban)事器(qi)取得(de)切确(que)的时(shi)候(hou)信息,用(yong)于调剂终端装(zhuang)备(bei)(bei)本(ben)身(shen)地(di)(di)点(dian)体系的时(shi)候(hou),到达同步时(shi)候(hou)的目标。播(bo)(bo)(bo)送(song)形式(shi)是sntp时(shi)候(hou)办(ban)事器(qi)周(zhou)期性地(di)(di)发送(song)动静给(ji)**的IP播(bo)(bo)(bo)送(song)地(di)(di)点(dian)或(huo)IP多(duo)播(bo)(bo)(bo)地(di)(di)点(dian),终端装(zhuang)备(bei)(bei)监听sntp时(shi)候(hou)办(ban)事器(qi)地(di)(di)点(dian)来取得(de)时(shi)候(hou)信息。


sntp时(shi)(shi)(shi)(shi)(shi)候办(ban)(ban)(ban)(ban)事(shi)(shi)器(qi)首要是以收(shou)集(ji)(ji)授(shou)时(shi)(shi)(shi)(shi)(shi)的(de)体例停止授(shou)时(shi)(shi)(shi)(shi)(shi)的(de),收(shou)集(ji)(ji)授(shou)时(shi)(shi)(shi)(shi)(shi)操纵便利并且授(shou)时(shi)(shi)(shi)(shi)(shi)规模广(guang)精度(du)高(gao)。如SYN2101NTP收(shou)集(ji)(ji)时(shi)(shi)(shi)(shi)(shi)候办(ban)(ban)(ban)(ban)事(shi)(shi)器(qi)是领受卫星时(shi)(shi)(shi)(shi)(shi)候信息的(de)输入NTP收(shou)集(ji)(ji)、脉冲、串(chuan)口等时(shi)(shi)(shi)(shi)(shi)候信息传输给(ji)终端装(zhuang)备,并保障局域网(wang)内(nei)一切(qie)装(zhuang)备时(shi)(shi)(shi)(shi)(shi)候同步(bu)。SYN2101NTP收(shou)集(ji)(ji)时(shi)(shi)(shi)(shi)(shi)候办(ban)(ban)(ban)(ban)事(shi)(shi)能够或(huo)许(xu)(xu)挑(tiao)选多(duo)种输入源,它的(de)收(shou)集(ji)(ji)授(shou)时(shi)(shi)(shi)(shi)(shi)精度(du)0.5-10ms,吞吐量为(wei)4000次/秒能给(ji)上万台终端装(zhuang)备授(shou)时(shi)(shi)(shi)(shi)(shi)。NTP收(shou)集(ji)(ji)时(shi)(shi)(shi)(shi)(shi)候办(ban)(ban)(ban)(ban)事(shi)(shi)的(de)时(shi)(shi)(shi)(shi)(shi)钟(zhong)源为(wei)高(gao)精度(du)温(wen)补晶(jing)振(zhen),也能够或(huo)许(xu)(xu)挑(tiao)选恒温(wen)晶(jing)振(zhen)、铷(ru)原(yuan)子(zi)钟(zhong)、顺(shun)服(fu)恒温(wen)晶(jing)振(zhen)模块、顺(shun)服(fu)铷(ru)钟(zhong)模块等,时(shi)(shi)(shi)(shi)(shi)钟(zhong)源能够或(huo)许(xu)(xu)有用的(de)停止定(ding)时(shi)(shi)(shi)(shi)(shi)。SYN2101NTP收(shou)集(ji)(ji)时(shi)(shi)(shi)(shi)(shi)候办(ban)(ban)(ban)(ban)事(shi)(shi)具备干接(jie)点告(gao)警、授(shou)时(shi)(shi)(shi)(shi)(shi)软(ruan)(ruan)件(jian)Windows体系SNTP授(shou)时(shi)(shi)(shi)(shi)(shi)软(ruan)(ruan)件(jian)、批处(chu)置(zhi)软(ruan)(ruan)件(jian)对批量客(ke)户端指(zhi)向时(shi)(shi)(shi)(shi)(shi)候办(ban)(ban)(ban)(ban)事(shi)(shi)器(qi)IP、对时(shi)(shi)(shi)(shi)(shi)候隔(ge)等停止设(she)置(zhi)、办(ban)(ban)(ban)(ban)理(li)软(ruan)(ruan)件(jian)对时(shi)(shi)(shi)(shi)(shi)候办(ban)(ban)(ban)(ban)事(shi)(shi)器(qi)任(ren)务状况(kuang)及任(ren)务参数停止设(she)置(zhi)装(zhuang)备摆设(she)及监控、防火(huo)墙、QoS功(gong)效(xiao)、SYN-flood进(jin)攻等功(gong)效(xiao)。

SYN2101NTP收集时候办事器具备精度高、不变性好、功效强、性价比高、操纵简略等特色,且普遍操纵于黉舍、病院、电力、金融、通讯、交通、广电等各个行业。
