A system for providing a multi-delivery-method policy-controlled client proxy is disclosed. The system may receive a request for a network service from a client. Based on the request for the network service, the system may detect the presence of a client proxy associated with the client. If client proxy is detected, the system may provide a data object that includes information that indicates that the client proxy is a primary source for content that may be requested by the client. The system may redirect, based on the data object, a request for the content received from the client to the client proxy. The system may then obtain, via the client proxy, the content by utilizing a delivery method that is selected based on a policy. Finally, the system may provide, via the client proxy, the content to the client.

Multi-delivery-method policy-controlled client proxy

A system for providing downstream bandwidth aware adaptive bit rate selection is disclosed. The system may determine a fixed bandwidth available to transmit content to a client on a second network. The system may connect to a first network, which may be configured to have no specific bandwidth constraints, to obtain the content. Once the system is connected to the first network, the system may receive, from the first network, a content segment of the content that is encoded at a first bandwidth. The first bandwidth may be less than or equal to the lesser of the fixed bandwidth available to transmit the content to the client on the second network and a first adaptive bit rate that is selected based on a congestion condition experienced on the first network. The system may then transmit the content segment at the first bandwidth to the client on the second network.
