这几天上了外文网站，发现老外善用"loadbalance"解決WAN上x享数码反制一卡一卡的问题!!
 
 看來国內的共享，要大升级了
 
 双DNS+双卡 load balance+双网load balance +高速双CPU伺服器+VLAN---------可能成为未來主流
 
 # LOADBALANCE : .. { , .. , }
 
 #
 
 # multiple loadbalance groups can be configured, by adding multiple lines
 
 . W" _7 {: W# R% Q0 E3 _! d3 L" u# warning: restart is required, when loadbalance group config changes
 
 #
 
 #example 1: load balance requests for three identical cards
 
 #
 
 # LOADBALANCE : /dev/ttyS0 /dev/ttyS1 /dev/ttyS2
 
 #
 
 #example 2: load balance requests for two almost identical cards, sid 0df3 and 0de1 are only available
 
 #on one of the cards, so requests for these sids shouldn't be loadbalanced
 
 #
 
 # LOADBALANCE : /dev/ttyS5 /dev/ttyS6 { 0df3,0de1 }
