the system comprises a judging module, a communication maintenance module and a communication maintenance module, wherein the judging module is used for sending an acquisition request of a communication maintenance cycle to a target server to be maintained and judging whether the communication maintenance cycle exists in the target server;
the setting module is used for setting the communication maintenance period as a period for presetting the communication connection maintenance between the target client and the target server if the communication maintenance period exists in the target server;
a generating module, configured to generate a detection maintenance period based on a preset period detection algorithm if the communication maintenance period does not exist in the target server, and set the detection maintenance period as a period for maintaining communication connection between the target client and the target server;
wherein, the judging module is specifically configured to:
establishing communication connection with a target server to be maintained;
sending an acquisition request of a communication maintenance period to the target server, and receiving request feedback information;
analyzing data in the request feedback information, and judging whether the communication maintenance period exists in the target server;
wherein the generating module comprises:
the reading unit is used for reading a preset detection timer, setting detection time length and assigning the detection time length to the time length of the detection timer;
the judging unit is used for judging whether data transmission exists between the target server and the detection timer in the duration of the detection timer;
the increasing unit is used for assigning the detection duration to the duration of the detection timer and detecting again if data transmission exists;
a sending unit, configured to send a maintenance data packet to the target server if there is no data transmission;
the setting unit is used for setting the detection duration as a detection maintenance period based on the reply condition of the target server to the maintenance data packet;
wherein the setting unit is specifically configured to:
judging whether the target server replies the maintenance data packet or not;
if not, reestablishing the communication connection with the target server, reducing the numerical value of the detection duration, and assigning the reduced detection duration to the duration of the detection timer;
if so, setting the detection duration as a detection maintenance period according to the reply history of the maintenance data packet;
wherein, the setting unit may further specifically be configured to:
judging whether the target server replies to the last sent maintenance data packet or not according to the reply history of the maintenance data packet;
if the last sent maintenance data packet is replied, increasing the value of the detection duration, and assigning the increased detection duration to the duration of the detection timer;
if the last sent maintenance data packet is not replied, setting the detection duration as a detection maintenance period;
wherein, the generating module may be further specifically configured to:
analyzing the communication connection between the target client and the target server to acquire the attribute information of the communication connection, wherein the attribute information comprises: an IP address and a port number corresponding to the communication connection;
matching attribute information corresponding to the communication connection with restriction information in a preset update restriction list, wherein the restriction information comprises: the IP address and the port number corresponding to the update limit list;
judging whether the limitation information and the attribute information have matched IP addresses and/or port numbers;
if the IP address and/or the port number matched with the limiting information and the attribute information exist, deleting the data of the detection maintenance period to prevent the maintenance of the communication connection;
and if the IP address and/or the port number which are matched with the limiting information and the attribute information do not exist, sending the setting information of the detection maintenance period to the target client so as to set the period of sending the maintenance data packet of the target client.
4. A communicatively connected maintenance device, comprising: a memory having instructions stored therein and at least one processor, the memory and the at least one processor interconnected by a line;
the at least one processor invoking the instructions in the memory to cause the maintenance device of the communication connection to perform the maintenance method of the communication connection of any of claims 1-2.
5. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out a method of maintaining a communication connection according to any one of claims 1-2.
