如何流畅的收听 BBN

  BBN 圣经广播网是北美的广播福音机构,拥有8国语言的节目24小时发送。

  其华语广播是通过网络播出的,根据平时收听的经验:BBN的网络广播服务是由 LLNW Limelight Networks 承载的,虽然LLNW有启用CND,但感觉其不是非常智能,尤其是对中国听众来说,常常不能选取到最优路径,以致于收听断断续续,个别地区甚至是不能连续收听。要解决此问题:用户端的最好办法就是通过修改本机 HOSTS 文件手动选择最优服务器。我通过 nslookup 的方法,查询到约50多台位于不同数据中心的LLNW媒体服务器,先贴出下面几个IP地址:

68.142.79.35
69.28.146.234
69.28.176.138
203.77.186.31
69.28.176.133
69.28.151.230
69.28.159.75
68.142.83.228

  如果你也遇到同样问题,可以尝试跟我做:

  1 在你的计算机上,点左下角 开始 -> 运行 -> 输入 CMD -> 调出命令行工具;



  2 依次用PING命令测试我给出的8个IP,具体做法是:输入 PING -n 10 68.142.79.35 然后记下结果中 Average(平均延迟) 和 Lost(丢包率) 2个数值,同理PING其他几个地址,如果你有耐心,可以把 -n 后面的 10 变大一些,这样得出的结果更加可靠一些;



  3 把得到的8对 Average 和 Lost 数值进行比较:

A、基本原则是 Average 越小越好,Lost 越少越好;但 Average 大于 800ms,Lost 大于 25%的服务器地址不用考虑;Lost
的权重应大于Average。
B、比如第一IP地址:Average=300ms Lost=18%,第二IP地址:Average=500ms
Lost=9%,这个时候应该选择第二个,因为第二个的 Lost 比较少。

  4 选定最优的IP以后,用记事本打开系统的 HOSTS 文件,你也可以在 开始 -> 运行 使用这个命令快速打开,

notepad.exe %systemroot%\system32\drivers\etc\hosts


  5 在打开的 HOSTS 文件末端,输入一行:

69.28.159.75 bibleb.wm.llnwd.net




  6 保存修改,退出编辑,重新开启 Windows Media Player 播放器即可。

  注意一点:如果播放器提示“找不到播放文件”,那可能是写错IP地址,或者该IP地址的服务器暂时不在线,请纠错或重选一个IP地址后再试播放。

  如果你用PING测试,都是 Request timed out 的结果,那说明你的网络禁止了ICMP的PING包,此法不适合你。

  最近阶段由于台湾地震的缘故,所有地址都有丢包情况。我是杭州电信ADSL的网路,LLNW自动给出7个IP地址都延迟丢包严重,根本无法收听,我照此法手动选择了69.28.159.75 这个IP,收听基本无断。

最近花了一点时间,简单遍历了 LLNW 的媒体服务器:

目前找出如下几个数据中心的服务器:

scds??.ams.llnw.net
scds??.dal.llnw.net
scds??.iad.llnw.net
scds??.lax.llnw.net
scds??.lga.llnw.net
scds??.ord.llnw.net
scds??.phx1.llnw.net
scds??.sea.llnw.net
scds??.sjc.llnw.net

?? 表示0-50的数字。
