Abstract: Apparatus and methods for optimizing data transmission between two hosts via a network device. The network device initially allows a first connection to be established between the two host devices. This first connection is logically established directly between the host devices without modification by the network device. The network device analyzes data transmitted via the first connection and determines whether to allow the first connection to continue without intervention by the network device, or whether to split the connection into separate TCP connections with the network device as intermediary. The network device maintains connection state and emulates both host devices to allow the first connection to be split without disrupting the communication at either host device.

Abstract: Methods and systems for delivering multimedia content in various telecommunications networks while optimizing quality of experience (QoE). The described methods and systems implement a fast processing path and a slow processing path. In the fast processing path, minimal packet processing is performed to reduce latency. In the slow processing path, increased packet processing is performed to identify media sessions and to perform further data processing. The slow processing path can be used in an online or offline mode, depending on a current flow state.

Abstract: Methods and systems for transcoding from an input media stream to an output media stream, wherein the input media stream and the output media stream are in an indexed file format. The methods and systems are capable of generating an efficiently coded media file where the movie box is generated and sent before transcoding is complete, while maintaining acceptable and consistent quality throughout and minimizing the total size of the file.

Abstract: Systems and methods of controlling access to a multimedia stream in a media streaming session from a multimedia server to a requesting device via a network. The systems and methods facilitate receiving a primary request for the multimedia stream from the requesting device; determining whether to allow access to the primary request from the requesting device in accordance with at least one media session policy; and if access is permitted, then generating a secondary request corresponding to the primary request; providing the secondary request to the multimedia server; receiving a first multimedia stream from the multimedia server in response to the secondary request; determining whether to transmit the first multimedia stream or a second multimedia stream based on the at least one media session policy; and transmitting either the first multimedia stream or the second multimedia stream to the requesting device as indicated by the at least one media session policy.
