Allocating buffer for TCP proxy session based on dynamic network conditions

A non-transitory computer readable storage medium having embodied thereon instructions, the instructions being executable by a processor to perform a method for allocating buffers for a TCP proxy session between a client and a server, the method comprising:

• monitoring dynamic server side network behaviors for a server side session of the TCP proxy session and dynamic client side network behaviors for a client side session of the TCP proxy session;
• and
• allocating capacity for a server side buffer and capacity for a client side buffer in a memory buffer based on the dynamic server side network behaviors, the dynamic client side network behaviors, and a weighted average of a capacity of the memory buffer, the allocating comprising:
• calculating a maximum capacity for the server side buffer and a maximum capacity for the client side buffer based on the dynamic server side network behaviors, the dynamic client side network behaviors, and the weighted average of the capacity of the memory buffer, and
• allocating the capacity for the server side buffer and the capacity for the client side buffer based on the maximum capacity for the server side buffer and the maximum capacity for the client side buffer,
• the monitoring and calculating further comprising:
• measuring a server side data packet round trip time (RTT), the client side data packet RTT, a server side transmission rate, and a client side transmission rate, and
• calculating the maximum capacity for the server side buffer and the maximum capacity for the client side buffer using the server side data packet RTT, the client side RTT, the server side transmission rate, the client side transmission rate, and the weighted average of the capacity of the memory buffer.

A system for allocating buffers for a TCP proxy session between a client and a server comprising:

• a processor;
• and
• a memory, the memory storing instructions, the instructions executable by the processor to perform a method, the method comprising:
• monitoring dynamic server side network behaviors for a server side session of the TCP proxy session and dynamic client side network behaviors for a client side session of the TCP proxy session;
• and
• allocating capacity for a server side buffer and capacity for a client side buffer in a memory buffer based on the dynamic server side network behaviors, the dynamic client side network behaviors, and a weighted average of a capacity of the memory buffer, the allocating comprising:
• calculating a maximum capacity for the server side buffer and a maximum capacity for the client side buffer based on the dynamic server side network behaviors, the dynamic client side network behaviors, and the weighted average of the capacity of the memory buffer, and
