Users enter the www.test.net.tw depends on the following priority.
The 1st user enter 61.11.11.11 server
The 2nd user enter 211.22.22.22 server
The 3rd user enter 211.22.22.22 server
(Finished to distribute the Round-Robin Priority)
The 4th user enter 61.11.11.11 server
(Restart to distribute the Round-Robin Priority)
The 5th user enter 211.22.22.22 server
The 6
t h
user enter 211.22.22.22 server
When the 3
rd
user enter
, the enter timing is over 1 in the setting of the weight priority with
the IP (61.11.11.11) , so the inbound load balance will distribute the 3
rd
user to the weight priority of 2 with
the IP (211.22.22.22) . When finished all the weight priority allocate, the system will re-connect all the user
and follow the weight priority distribution again. This is the so called inbound load balance, which can
distribute the round –robin mode to many users who link to the
web server depends
on the weight priority.
The less MX priority number has the highest priority. For example, the user A sends a mail to user B of
The user A send the mail through hinet.net.tw (SMTP server), and the hinet.net.tw will
determine which way the mail.test.net.tw to send the mails depends on the DNS search.
First of all, we can look for the MX record in mail.test.net.tw.：
Name Type Address
Reverse
Weight
Priority
mail.test.net.tw MX smtp1.test.net.tw

mail.test.net.tw MX smtp2.test.net.tw

The MX record in mail.test.net.tw
It is because the 1 number has the top priority, so the server will try to send mails through
the host of smtp1.test.net.tw (through SMTP Protocol). If it failed to send these mails, then
the mails would be sending through the second priority of smtp2.test.net.tw.
