Described embodiments provide systems and methods for inferring a network type and network conditions. The system includes a packet capturing engine configured to capture a plurality of network packets from a plurality of TCP network connections. The system includes a packet analyzer configured to analyze the plurality of network packets to generate a plurality of metrics. The system includes a network classifier configured to infer network types of the plurality of TCP connections based on the plurality of metrics and at least one classification model. The system also includes a conditions ranking engine configured to estimate a level of network congestion for each TCP connection based on the plurality of metrics and the network types.

Inferring radio type from clustering algorithms

Inferring congestion and signal quality

An apparatus and method of providing improved throughput on delay-based congestions comprising a packet engine and a delay-based congestion controller are provided. The packet engine detecting a delay jitter that is caused by a layer 2 retransmission of a data packet, is configured to measure a round trip time (RTT) value. The delay-based congestion controller is configured to receive the RTT value and to determine a smoothed RTT (SRTT) value using the RTT value and one or more moving average functions. The delay-based congestion controller is also configured to, if the SRTT value is smaller than a set minimum SRTT value, assign the SRTT value to the set minimum SRTT value. The delay-based congestion controller is further configured to, if the SRTT value is larger than a set maximum SRTT value, assign the SRTT value to the set maximum SRTT value.

A method of web content and web services insertion is provided. The method includes receiving response data sent in response to request data, wherein the response data comprises a response header and a first webpage. The method also includes after a determination that insertion data is to be included with the first webpage, updating the response data by adding insertion data to the first webpage. The insertion data includes a script element that identifies a script that includes an instruction to display a second webpage within the first webpage. The method also includes providing the updated response data.

Methods and systems for secure in-network insertion of web content and web services

A system and method that allows Rich Internet Applications content to be adapted for a web browser on a mobile device without requiring an installation of an RIA player. The method comprises receiving processing a request by communicating with the web server to acquire the RIA file and the parameters used to instantiate the RIA file, adapting the RIA content of the RIA file for display in the web browser without requiring an RIA player at the mobile device, and providing adapted RIA content to the web browser.
