RouterOS v6.29 新功能 \"FastTrack\"
作者: QQ:86698456  点击次数:   添加时间: 2017-04-08

 

从v6.29rc9, 将引入新的功能FastTrack,根据官方解释可以使你的路由器Firewall/NAT性能提升5倍,6.29rc9大致新增内容如下:
 
*) ipv4 fasttrack fastpath - accelerates connection tracking and nat for marked connections (more than 5x performance improvement compared to regular slow path conntrack/nat) - currently limited to TCP/UDP only;
 
*) added ~fasttrack-connection~ firewall action in filter/mangle tables for marking connections as fasttrack;
 
*) added fastpath support for bridge interfaces - packets received and transmitted on bridge interface can go fastpath (previously only bridge forwarded packets could go fastpath);
 
*) packets now can go half-fastpath - if input interface supports fastpath and packet gets forwarded in fastpath but output interface does not support fastpath or has interface queue other than only-hw-queue packet gets converted to slow path only at the dst interface transmit time;
 
官方介绍FastTrack= FastPath + Conntrack,主要特点为:
1、FastTrack加速指定的连接跟踪条目的数据包处理
2、FastTrack具备Full NAT支持
3、与普通的连接跟踪和NAT性能提升5倍
4、firewall filter/mangle菜单下新增fasttrack-connection选项
5、支持IPv4 TCP/UDP连接跟踪条目
6、工作方式类似于“mark-connection” 添加连接跟踪标记,并允许数据包被定义为FastTrack
7、并非所有的数据包都能被FastTrack处理,有一些数据包将仍然使用普通的Conntrack(连接跟踪)
 
x86是不支持FastTrack(因为FastPath不支持),经过测试FastTrack使用上有较多限制,例如在VLAN、PPP等协议启用后,不能开启
