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.

Systems and methods for correlating multiple TCP sessions for a video transfer

Semantic data corresponding to video data may be received. Next, the received semantic data corresponding to the video data may be analyzed. Caching decisions may then be made based upon the analysis of the received semantic data corresponding to the video data.

Utilize extra web semantic for video caching

A user device may send a request for a data file to an access point. The user device may then receive, from the access point, data indicating that a segment of the data file has been previously cached in a local cache at the access point. In response to receiving the data, the user device may display an indicator configured to indicate that the segment of the data file is cached in the local cache.

Method and system to locally cache and inform users of partial video segments and data objects

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.
