Domain name in above-mentioned page request is sent to after dns server, and dns server may inquire the domain name
Multiple effective IP address are currently corresponded to, such as ip [1], ip [2], ip [3] ..., i.e. IP address sequence.
In the prior art, it is assumed that dns server returns multiple effective IP address, such as ip [1], ip [2], ip
[3] ..., then existing network information browsing apparatus can first attempt to establish TCP connection with ip [1], issue SYN to ip [1] and ask
It asks.SYN is that TCP/IP establishes the handshake request signal used when TCP connection.It establishes between client and server normal
When TCP is connected to the network, client computer issues a SYN message first, and server is received using SYN+ response (ACK) response expression
This message, last client computer are responded again with ACK message.It can just set up between client and server so reliable
TCP connection, data can just be transmitted between client and server.
In the prior art, it if network information browsing apparatus was not successfully established TCP connection with ip [1] in 3 seconds, weighs
Second of SYN request newly is initiated to the ip [1], the time interval of second of SYN request is 6 seconds, i.e., the no and ip in 6 seconds
[1] it is successfully established TCP connection, then initiates third time SYN request to the ip [1] again, the time interval of third time SYN request is
9 seconds, i.e., it is not successfully established TCP connection with ip [1] in 9 seconds, then terminates the SYN request process to the ip [1], then downwards
One IP address, that is, ip [2] initiates SYN request.Requesting the process for establishing TCP connection with the ip [2] and above-mentioned ip [1] similarly,
It is not successfully established TCP connection in 3 seconds, then initiates second of SYN request, if not being successfully established TCP company in 6 seconds
It connects, then initiates third time SYN request, if not being successfully established TCP connection in 9 seconds, turn to next IP address and repeat
The above process is executed, then executes subsequent resource acquisition, parsing, drafting until successfully establishing TCP connection with certain IP address
The operation such as upper screen, or if all IP address returned with dns server are not all successfully established TCP connection, this net
Network information browse failure.
