The method of vertical connection is applied between the IP hard disks and server.The method for establishing connection comprises the following steps：
Step 110, the IP hard disks generation establishes TCP connection for request between the IP hard disks and the server
TCP connection request.
IP, English full name be Internet Protocol, the agreement that Chinese full name interconnects between network.IP hard disks are
A kind of hard disk being connected by Ethernet interface with server, IP hard disks can be assigned corresponding IP address.TCP, English full name
For Transmission Control Protocol, Chinese full name is transmission control protocol.
The IP hard disks can actively generate a TCP connection request, and a TCP can also be just generated under the conditions of certain and is connected
Connect request.In the present embodiment, the IP hard disks are asked to actively generate a TCP connection.In generation TCP connection request
Afterwards, step 120 is performed.
Step 120, the IP hard disks send the TCP connection to the server and ask.That is, TCP connection please
Seeking Truth is actively sent by IP hard disks, and according to Transmission Control Protocol, the end of a transmitting terminal can be consumed by sending a TCP connection request
Mouthful, therefore, a port of IP hard disks can be consumed at this time.
Step 130, server receives the TCP connection request that IP hard disks are sent, and the TCP connection request is used to ask in institute
It states and establishes TCP connection between IP hard disks and the server.
Step 140, the server responds the TCP connection request, and TCP connection is established between the IP hard disks.
Step 150, the IP hard disks receive the TCP connection request response that the server is sent, with the server it
Between establish TCP connection.
The IP hard disks send the TCP connection request, and the server simply receives and respond the TCP connection please
It asks, without sending the TCP connection request, therefore, according to Transmission Control Protocol, transmitting terminal can be consumed by sending a TCP connection request
Port, therefore the port without consuming a receiving terminal, after this method, will not consume the port of server.
By taking current Transmission Control Protocol as an example, the step of establishing TCP connection is specifically described：
First, SYN bags (the TCP companies of TCP connection are established in generation for request in client (IP hard disks) between server
Connect request)；
Then, client (IP hard disks) is by SYN bags (SYN=j) to server, and enters SYN_SEND states, waits clothes
Business device confirms；
Again, server receives the SYN (ACK=j+1) that client must be confirmed after SYN bags, while oneself also sends SYN bags
(SYN=k), i.e. SYN+ACK bags, at this point, server enters SYN_RECV states；
Finally, client (IP hard disks) receives the SYN+ACK bags of server, is sent to server and confirms bag ACK (ack=k
+ 1), this bag is sent, and client and server enters ESTABLISHED states, completes TCP connection, client (IP hard disks)
Start to transmit data with server.
Therefore, the method for above-mentioned foundation connection when the IP hard disks and the server are established and connected, passes through the IP
Hard disk sends TCP connection request to the server, and therefore, the server often establishes TCP connection with an IP hard disk, can disappear
The a port of the IP hard disks is consumed, a port without consuming the server, even if so as to need to connect
IP hard disks it is more when, the port number of the server can also meet use demand, so as to solve in the prior art by
TCP connection often is established with an IP hard disk in the server, a port of the server will be consumed, causes needing
When the IP hard disks to be connected are more, the technical issues of port number for the server occur is unsatisfactory for use demand.
