Stateless transmission control protocol connections

A non-transitory computer-readable medium storing instructions which, when executed by a processing system including at least one processor, cause the processing system to perform operations, the operations comprising:

• receiving a first message from a client device requesting an establishment of a transmission control protocol connection, wherein the first message contains a first sequence number for the transmission control protocol connection;
• calculating, based on the first sequence number and a first integer from a list of a plurality of randomly generated integers, a second sequence number for the transmission control protocol connection;
• sending a second message to the client device in response to the first message, wherein the second message contains the second sequence number;
• receiving a fourth message containing an acknowledgement number and data;
• extracting a second integer from the acknowledgement number;
• determining whether the fourth message originated with the client device by comparing the second integer to the first integer;
• and
• sending a fifth message to the client device, wherein a type of the fifth message is selected based on an outcome of the determining.
