A system and method for optimizing a multimedia transmission from a content source to an end user over a link. The wireless content switch comprising an upstream port for receiving one or more data packets and for transmitting one or more status to a content source, a downstream port for transmitting the one or more data packets and for receiving one or more status from an end user, at least one processing unit coupled to the upstream and down stream ports, and memory for storing the one or more data packets responsive to receiving the data packets. Optimization code is stored in the memory, the optimization code, when executed, receiving at least one data packet, transmitting the data packet, receiving status information, transmitting status information, determining quality of service assigned to the end user, determining session specific status for the end user, and transmitting the quality of service and session specific status.

Multimedia traffic optimization

A method, apparatus, and instructions for establishing a virtual communication channel between applications on different nodes in which one node may be using a communication protocol stack based on one protocol, such as SS7, and another node may be using a communication protocol stack based on another protocol, such as IP. Alternatively, a virtual communication channel may be provided between applications on different nodes in which both nodes use a communication protocol stack based on IP to communicate with each other, but carry SS7 traffic through the communication channel. A gateway is provided in which both SS7 and IP are supported. The gateway allows for logical transport of signaling messages between peer applications on different nodes. Messages for SS7 are placed in data packets for transport to a destination using an IP connection or link to the destination. Header information also is placed into the data packet to allow for routing of the messages when the packet is received at the destination.
