Abstract
Described embodiments provide a server for transferring data packets of streaming data sessions between devices. The server includes an accelerator that, for received data packets, i) extracts header fields of the packets, ii) determines, based on the header fields, a destination for the packets, and iii) provides the packets to the destination. For data to be transmitted, the accelerator i) groups the data into packets, ii) generates header fields for the packets, and iii) provides the packets to the network. A memory arbiter manages accesses to memory that buffers data and stores keys corresponding to the data sessions. A storage medium stores media files corresponding to the data sessions. A key manager includes i) a first memory for storing a master key of the server, ii) a second memory for storing one or more keys corresponding to the data sessions, and iii) a processor to encrypt and decrypt data.
