PCC 5线负载均衡脚本

583626612

以下为PCC 5线负载均衡脚本，能正常工作，但是有一个问题，中间有条线路PPPOE-out3，无论如何没有流量，
本人钻研数日，都无法开解，困惑至极，请高人指教！将之修改完善，造福大众！

当然是PCC好。

经过几天的观察，发现PCC流量的确不如NTH均衡，PCC不但考虑数据流的源和目标，更多的顾忌数据流的路径，强调原路来，原路去，这样就导致了一些出口拥堵，其他出口可能没有流量的情况。
网吧还是用NTH好，单线带宽够大方可考虑PCC。

      从3.24版本开始，ROS引入新的负载均衡概念，就是PCC匹配器（per- connection-classifier），这个匹配器允许你分离传输流，做到平衡流量的能力，这里面可以设置设置选择根据源地址，源端口，目标地址，目标端口来进行处理，现在论坛里已经有相关的设置帖子，一般是使用所有地址来进行处理，即“both addresses”（使用这种方式才能解决网银问题，如果选择按port方式就会跟NTH一样需要处理网银端口走线），这种处理方式是目前来讲最全面的一种了。很多人以为NTH应该跟PCC差不多，其实不然，虽然大家都是依据各自的规则来进行均衡，两者都不可能达到真正的1+1=2，但是事实上，PCC内置了一个连接重置规则，比如说，你是两条ADSL均衡，使用NTH时就会发现，如果其中一条线路满载，客户机PING外网的话，会出现一下延迟很大，一下延迟很小的情况，如果使用PCC，则不会如此，当其中一条线路满载时，PING连接将会被丢弃再重新选择另一条线路，这样就会达到带宽更充足的利用，从而概念上达到1+1接近于2。（图1显示的是当ADSL1线路满载的情况下，ping值依然很低）所以，选择PCC是更有好利的，况且PCC已经解决了网银问题，以及部分软件走线不兼容问题，不要吝惜你稳定使用着的ROS旧版本，尽管升级吧，至少也得升到3.30版。


这是我在rc论坛看到的.现在看来各种说法都有.到底哪个正确?

我的PCC做出来，就是只跑默认路由的那一根线是怎么回事呢？望赐教啊。。。
