SYSTEMS AND METHODS FOR DYNAMIC RECEIVE BUFFERING

摘要

The present disclosure relates to methods and systems for dynamically changing an advertised window for a transport layer connection. A device can receive data from a server destined for an application. The device identifies the size of the application buffer corresponding to the application and advertises the application buffer size as a window size to the server. The device stores the data in the device memory. The device then determines the memory usage by comparing the memory usage to one or more predetermined thresholds. If the device determines that the memory usage is below a first predetermined threshold, the device can implement an aggressive dynamic receive buffering policy in which the device increases the advertised window size by a first increment. If the device determines that the memory usage is above the first threshold and below a second threshold, the device executes a more conservative dynamic receive buffering policy.

主权项

1. A method for dynamically changing an advertised window for a transport layer connection, the method comprising:
(a) receiving, by a device intermediary to a client and a server, a request from an application to establish a transport layer connection with the server, the application advertising a first window size for the transport layer connection; (b) establishing, by the device, the transport layer connection with the server, the device advertising a second window size to the server, the second window size set to the first window size, the transport layer connection having a maximum segment size; (c) storing, by the device, in memory of the device data received from the server via the transport layer connection; (d) determining, by the device, memory usage of the device is below a predetermined threshold; and (e) increasing, by the device responsive to the determination, the second window size advertised to the server by a predetermined increment of the maximum segment size.
