Detailed Description
The present invention will now be described in more detail with reference to the accompanying drawings, in which the description of the invention is given by way of illustration and not of limitation. The various embodiments may be combined with each other to form other embodiments not shown in the following description.
Example one
The embodiment provides a data transmission system based on TCP, and aims to solve the problem that in the existing TCP transmission process, once a client and a server are disconnected, data transmission is interrupted. Specifically, referring to fig. 1, the data transmission system includes a client 1, a node pool 2, and a source server 3.
The client 1 is used by a client, and needs to perform data interaction with the source server 3, and the client 1 supports environments such as a PC, an IOS, an Android, an HTML5, and the like, and may be, but not limited to, any one of a mobile phone, a tablet, a notebook, a server, and a processor.
The node pool 2 includes a plurality of transit servers 21. For any transit server 21, it is communicatively connected to the client 1 and also to the source server 3. The client 1 can realize the communication connection with the transit server 21 by means of three-way handshake. Correspondingly, the transit server 21 may also implement a communication connection with the source server 3 by means of three-way handshake. It can be noted that the number of the node pool 2 is not limited herein, and may be increased or decreased according to actual situations. The transit server 21 may be, but is not limited to, any one of an entity server, a cloud server, and a processor. It should be noted that, after receiving the data sent by the client 1/the source server 3, each transit server 21 stores the data to avoid data loss.
The source server 3 is in communication connection with each transit server 21, so that the client 1, the transit servers 21 and the source server 3 in the system are in a one-to-many, many-to-one architecture. The source server 3 may be, but is not limited to, any one of an entity server, a cloud server, and a processor.
It is worth mentioning here that the client 1, a transit server 21, and the source server 3 may obtain a transmission channel, which transmits data based on the TCP/IP protocol. Since the node pool 2 has a plurality of transit servers 21, the system has a plurality of transmission channels, and preferably 20 to 30.
It should be noted that, in general, the system has only one transmission channel to transmit data, and of course, multiple transmission channels may also transmit data. However, the system prefers one current channel in view of resource saving. Correspondingly, the transit server 21 corresponding to the current channel is recorded as the current node.
When the connection between the current node and the client 1 and/or the source server 3 is abnormal, that is, when the communication of the current node is abnormal, the client 1 and/or the source server 3 switches the current channel to another transmission channel to continue data transmission. The cause of the communication abnormality is not limited to one or more combinations of network fluctuation, disconnection, hacking, and the like.
The specific operation process of the technical scheme can refer to the following description, when the client 1 uses the current channel to transmit data, the data is output by the client 1, and then is forwarded to the source server 3 through the relay server 21, so that the data transmission is realized; when the connection between the current node and the client 1 and/or the source service is abnormal, the client 1 switches the current channel to another transmission channel to continue data transmission between the client 1 and the source service 3.
It should be further noted that, when capturing the data transmission IP, a hacker attack can only capture the corresponding transit server 21, but cannot obtain the IP of the source server 3, so that the security of the source server 3 is ensured, and the defense effect of the system is better improved in combination with the switching of the current channel.
In summary, by establishing a plurality of transmission channels, and all the other transmission channels are standby channels, the transmission channels are switched when the network is abnormal, so that the data can be quickly recovered from transmission, thereby reducing the delay of the data interrupted by transmission, and further improving the user experience.
As an optional solution, the client 1 further has a real port and a disguised port. The real port is a virtual port, which is a port for the client 1 to issue data; the disguised port is a free virtual port which is randomly obtained, the number of the real ports is the same as that of the disguised port, and then the client 1 corresponds the real ports to the disguised port and establishes communication connection, so that the real ports are prevented from being attacked by hackers.
The virtual port is connected with the node pool 2 in a matching way. It should be noted that the number of the real ports may be one or more, and since the masquerade ports correspond to the real ports one to one, the masquerade ports may be one or more. When there is one hidden port, the hidden port and the transit service 21 are "one-to-many", and when there are a plurality of hidden ports, there may be "one-to-many" between the hidden port and the transit service 21, or "one-to-one" between the hidden port and the transit service 21. And are not limited herein.
For a specific operation process of the technical solution, reference may be made to the following description, when the client 1 issues the data a, the data a sequentially passes through the real port, the disguised port, and the transit server 21. Similarly, the source server 3 may also be configured with a real port and a masquerade port, and the source server 3 issues the data b, and the data b sequentially passes through the masquerade port-real port 1-transit server 2.
Further, the disguised port is arranged in one-to-one correspondence with the transit server 21, that is, the real port, the disguised port and the transit server 21 are arranged in one-to-one correspondence, so that when the disguised port and the transit server 21 are attacked, the switching of the transmission channel is performed, and the real port and the client are protected.
Example two
The embodiment provides a data transmission method based on TCP, and aims to solve the problem that in the existing TCP transmission process, once a client is disconnected with a server, data transmission is interrupted. Specifically, referring to fig. 2, the data transmission method includes the following steps S10 to S30.
Step S10, establishing a plurality of transmission channels, wherein each transmission channel corresponds to a transfer server, and any server is connected to a source server from a client through the corresponding transfer server;
step S20, selecting a transmission channel and recording as the current channel for data transmission, and recording the transit server corresponding to the current channel as the current node;
and step S30, when the communication of the current node is abnormal, switching the current channel to other transmission channels to continue data transmission.
The execution device of the data transmission method can be a client or a source server. The method and the device perform switching of transmission channels when the network is abnormal so that data can be quickly recovered to be transmitted, and therefore delay of data interrupted in transmission is reduced. For specific description, reference may be made to the related description in the first embodiment, which is not repeated herein.
As an optional technical solution, the data transmission method further includes the following steps: acquiring a real port;
inquiring an idle port and recording as a covering port; and the disguise port corresponds to the real port and establishes communication connection, and the disguise port is matched with the real port to be connected with a node pool in a communication mode, wherein the node pool is provided with a plurality of transfer service terminals. Therefore, the defense capability of the system is improved, and the specific description of the step may refer to the related description in the first embodiment, which is not described herein again.
Furthermore, the disguise port and the transit server are arranged in a one-to-one correspondence manner, namely, the real port, the disguise port and the transit server are arranged in a one-to-one correspondence manner, so that when the disguise port and the transit server are attacked, the switching of the transmission channel is carried out, and the real port is protected.
Further, when the execution device is a client, the source server may also refer to the relevant settings of the client with respect to the real port and the disguise port, that is, the source server is also provided with the disguise port corresponding to the real port, and the disguise port is in communication connection with the node pool, so as to realize that data is transmitted in the "real port of the client-the virtual port of the client-the transit server-the disguise port of the source server-the real port of the source server", thereby improving the defense of the member server and improving the stability of the system; conversely, when the execution device is the source server, the client may refer to the above setting.
EXAMPLE III
The embodiment provides a data transmission method based on TCP, which is performed on the basis of the second embodiment. Specifically, referring to fig. 3, the step S20 of "selecting a transmission channel and recording as the current channel" includes steps S201 to S204.
Step S201, sending a first signal to a corresponding relay server via each transmission channel. The first signal may be a random packet. When the corresponding execution device outputs the first signal, it saves the transmission time t1 of the first signal.
The relay server receives the first signal, responds to the first signal to generate feedback information, and then sends the feedback information to the execution equipment. Wherein the feedback information includes the receiving time t2 of the first signal of the transit server.
Step S202, feedback information sent by each transfer server is received through a transmission channel.
Step S203, querying the sending time T1 of each first signal, and determining the transmission time length T of each first signal according to the sending time T1 and the receiving time T2 of the first signal, that is, T2-T1.
Step S204, selecting the transmission channel corresponding to the shortest transmission duration T as the current channel for data transmission. The shortest transmission time length T is selected to enable the speed of the current channel to be higher, so that the data transmission efficiency is improved.
It should be noted that, in the technical solution, each transmission channel may be opened, then a random data packet is sent to each transmission channel, and the transmission duration T corresponding to each transmission channel is determined according to steps S201 to S203, which may affect each other due to more opened transmission channels, so that the calculated transmission duration T is deviated from the actual transmission duration of data transmission after the current channel is opened, but the time spent in step S20 in the technical solution is short; in this technical solution, only one transmission channel may be opened, after receiving the feedback information, the transmission channel is closed and the next transmission channel is opened, and this is repeated until each transmission channel corresponds to the transmission duration T, and this technical solution simulates an actual process of data transmission, so that the calculated transmission duration T is closer to the actual transmission duration, but the time taken in step S20 is longer.
It can be understood that the execution device of the method is further provided with a duration threshold, and if the corresponding feedback information is not received within the duration threshold after the first signal is sent, the corresponding feedback information is abandoned and the next corresponding step is directly started, and the corresponding transmission duration can be recorded as zero. The duration threshold may be set by itself, and is not limited herein.
As an optional technical solution, the feedback information further includes a connection state of the relay server, and when the communication state of the relay server is abnormal, the relay server prohibits sending the feedback information or prohibits the corresponding transmission channel from being selected. The communication state of the transit server comprises the following steps: when any one of the connections is abnormal, the communication state of the transit server is considered to be abnormal, and the corresponding transmission channel should prohibit data transmission.
As an alternative solution, referring to fig. 4, the step S30 of "switching the current channel to another transmission channel" includes steps S301 to S303.
Step S301, inquiring and recording the transmission channel which is normally connected as an effective channel, namely, the corresponding transit server is normally connected with the client and the source server, and data can be transmitted.
It should be noted that, after the current channel is abnormal and switched, the previous current channel is reconnected to the client and the source server after the abnormal condition disappears, so as to be converted into an effective channel.
Step S302, inquiring the transmission time length T of each effective channel. The transmission time length T may be obtained in step S203 or may be updated. For example: after the selection of the current channel is completed, the execution device may also perform step S201 to step S203 individually to update each transmission duration T, so that the switching may be performed directly when the current channel is abnormal. The execution device may also perform step S201 to step S203 individually when the current channel is abnormal, so as to update each transmission duration T, and then perform switching of the transmission channels, which may ensure that the switched current channel is normal in operation, but may prolong the switching time.
Step S303, selecting the transmission channel with the shortest transmission time T from the effective channels as the current channel. By the technical scheme, the switching of the current channel is realized, and the reliability of the switched current channel is higher.
