Abstract: User equipments can download a video file by instantiating multiple video requests, each request specifying different parts of the video file. If each video request initiates a separate transmission control protocol (TCP) session, which is the case with an hypertext transfer protocol (HTTP) partial get request, then a network device in a communications network would be oblivious of contextual information, which indicates that the TCP sessions download different portions of the same video file. This disclosure provides systems and methods for correlating multiple TCP sessions so that a network device in a communications network can be aware of the contextual information.

Abstract: Mining information from network data traffic to determine interests of online network users is provided herein. A data packet received at a network interface device can be accessed and inspected at line rate speeds. Source or addressing information in the data packet can be extracted to identify an initiating and/or receiving device. The packet can be inspected to identify occurrences of keywords or data features related with one or more subject matters. A vector can be defined for a network device that indicates a relative rank of interest in various subject matters. Furthermore, statistical analysis can be implemented on data stored in one or more interest vectors to determine information pertinent to network user interests. The information can facilitate providing value-added products or services to network users.
