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.
