Abstract: Network operators are striving to find ways to provide stable video services amid a rapid increase in video traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes using a content adaptation engine (CAE). However, network operators failed to efficiently readdress video flows to CAEs. This disclosure provides systems and methods for efficiently readdressing video flows to CAEs.

Abstract: Systems and methods are used for receiving a video request from a user equipment for video to be downloaded; determining a link bandwidth status associated with the user equipment; in response to the link bandwidth status associated with the user equipment, determining whether to implement one or more additional processing functions associated with the video delivery; during the video delivery, repeating the determining such that the one or more additional processing functions associated with the video delivery can be implemented or not implemented at different times during the video delivery. These processing functions can include transrating, HTTP optimization, TCP optimization, and video pacing.

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: In one embodiment, a load balancer receives a message from a tunnel termination gateway (TTG) associated with a mobile device. The load balancer may receive messages from a plurality of TTGs. A gateway node in a plurality of gateway nodes in which to send the message is determined. The load balancer then assigns a NSAPI for use by the gateway node. For example, the NSAPI may be associated with a tunnel that is generated between the TTG and GGSN. The load balancer ensures that the assigned NSAPI is not currently in use at the gateway node. Thus, no overlapping of NSAPIs may occur even though the load balancer is processing messages from multiple TTGs for multiple gateway nodes.
