使用BBCP来提升跨互联网的数据传输速度

背景介绍:
目前项目在美国东西部以及欧洲都有服务器节点,跨互联网的数据传输速度很不稳定,之前我们主要是通过SCP以及Rsync等方式进行数据传输的。
无意间发现了BBCP这个软件之后,经过测试,效果非常好,速度提升效果很明显,并且传输速度一直比较稳定,同时支持日志以及失败后重试等参数,非常不错。

安装配置:

[aikaiyuan@aikaiyuan~]$ sudo wget http://www.slac.stanford.edu/~abh/bbcp/bin/amd64_rhel60/bbcp -O /usr/bin/bbcp
[aikaiyuan@aikaiyuan~]$ sudo chmod +x /usr/bin/bbcp

[dong@west-ads1 ~]$ sudo wget http://www.slac.stanford.edu/~abh/bbcp/bin/amd64_rhel60/bbcp -O /usr/bin/bbcp
[dong@west-ads1 ~]$ sudo chmod +x /usr/bin/bbcp

[aikaiyuan@aikaiyuan~]$ which bbcp
/usr/bin/bbcp
[aikaiyuan@aikaiyuan~]$ ssh west-ads1 which bbcp
/usr/bin/bbcp

[aikaiyuan@aikaiyuan~]$ cd dong

结论:

在上面的测试中,传输一个大小为2G的文件,使用BBCP耗时仅5分钟,而普通的SCP则耗时16分钟,速度提升超过60%。
