Distributed and scalable content streaming architecture

A system, comprising:

• an interface operable to receive a request from a device for a media stream, the request received at a controller, wherein the controller is a shared session controller configured to establish streaming sessions with a plurality of devices, wherein the shared session controller is shared by a plurality of content servers, wherein the controller is selected by a load balancer located between the controller and the device;
• a processor operable to select a server from the plurality of content servers operable to provide the media stream to the device, wherein the server transmits the media stream to the device using a transport protocol, wherein the plurality of content servers are configured to perform content streaming operations while offloading session management operations to the controller and the session controller is configured to perform session management operations while offloading content streaming operations to the plurality of content servers, wherein the plurality of content servers simultaneously transmit a plurality of media streams to the plurality of devices having a plurality of corresponding sessions established by the shared session controller, the plurality of content servers situated in different geographic locations and connected to a campaign server providing profile information associated with individual devices, the campaign server providing profile information for selecting replacement advertisements from a database to replace default advertisements in the media stream.

A non-transitory computer readable medium, comprising:

• computer code for receiving a request from a device for a media stream, the request received at a controller, wherein the controller is a shared session controller shared by a plurality of content servers, wherein the controller is selected by a load balancer located between the controller and the device;
• computer code for establishing a session at the session controller with the device, the controller configured to establish streaming sessions with a plurality of devices;
• computer code for selecting a server from the plurality of content servers to provide the media stream to the device, wherein the server transmits the media stream to the device using a transport protocol, wherein the plurality of content servers are configured to perform content streaming operations while offloading session management operations to the controller and the session controller is configured to perform session management operations while offloading content streaming operations to the plurality of content servers, wherein the plurality of content servers simultaneously transmit a plurality of media streams to the plurality of devices having a plurality of corresponding sessions established by the shared session controller, the plurality of content servers situated in different geographic locations and connected to a campaign server providing profile information associated with individual devices, the campaign server providing profile information for selecting replacement advertisements from a database to replace default advertisements in the media stream.
