Optimize for TCP
Flags
User can choose to enable TCP flags: “SYN”, “ACK”, “FIN”, “RST”, which means
data with above TCP Flags will get the highest priority to occupy bandwidth.
After enabled, router will enhance respond timeout of TCP control, in case that
data resend frequently.
Disable
Optimize for ICMP
Enable to optimize for ICMP, which means ICMP will get the highest priority to
occupy bandwidth. After enabled respond interval of PING control will be
shorter.
Note: if user click to enable “Optimize for TCP Flags”, “Optimize for Serial Data
Forwarding”, and “Optimize for ICMP” at the same time (these three services
are in the same priority level), router will automatically start Stochastic Fairness
Queuing (SFQ) strategy to make a fair bandwidth allocation, in case of one
service occupy all the bandwidth.
Disable

Data Forwarding

forwarding will get the highest priority to occupy bandwidth.
