Strict Security
Checking
VigorPro5300 Series User's Guide
Window size – It determines the size of TCP protocol
(0~65535). The more the value is, the better the performance will
be. However, if the network is not stable, small value will be
proper.
Session timeout /Queue timeout–Setting timeout for sessions
can make the best utilization of network resources. However,
Queue timeout is configured for TCP protocol only; session
timeout is configured for the data flow which matched with the
firewall rule.
Max. Queue length - When the network connection is not
stable, you can set large number for this setting to get better
performance. Yet large value will consume large resource.
Retransmission queue length – Type the number here as a base
for the router to verify if the retransmitted data is the same as the
old one.
For the sake of security, you might want the router executing
strict security checking for data transmission. The router
performance will be affected if you invoke strict security
checking.

virus.
