Optimization of dynamic performance of TCP layer for field in real time.

摘要

Abstract optimization of dynamic performance of TCP layer for field in real time, a method and system which minimizes the degradation of the data session in a connection of a radio link with a server endThe allocation of resources in a wireless communication device based on a real time under the conditions of the communication channel of the radio.The allocation of resources and the logic of performance monitoring (PTRA) monitors the configuration of radio access bearer (RAB) and quality of the radio link for communication links between the WCD.The server end. The logic PTRA defines the parameter of maximum size of the transmission unit (MTU) into a predetermined size associated with the radio link quality measure.In response to detection of a change in the configuration Rab.The logic ATPR performs a real time measurement of round-trip time (RTT) using individual RTTS associated with segments of the packet transmitted to a layer of the protocol below.In addition,The logic PTRA modifies at least one of a window of reception (rwin) of the transmission control protocol (TCP) and a transmission window TCP (twin) using the measures of RTT in real time and conFiguration Rab.
