A device may identify a proxy connection associated with a first device and a second device. An application buffer of the proxy connection may be associated with a first buffer size for at least one of the first device or the second device. The proxy connection may be associated with a video communication. The device may determine a set of parameters relating to the proxy connection. The device may determine a buffer allocation for the proxy connection based on the set of parameters. The device may perform an alteration to the application buffer of the proxy connection to cause the application buffer of the proxy connection to be associated with a second buffer size. The second buffer size may be different from the first buffer size.
