Abstract
A method and apparatus are described including receiving a route request message to establish a streaming route, determining a cost of a reverse route and traffic load introduced by the requested streaming route, discarding the route request message if one of wireless interference constraints for the requested streaming route cannot be satisfied and quality of service requirements for the requested streaming route cannot be satisfied, pre-admitting the route request message if wireless interference constraints for the requested streaming route can be satisfied and if quality of service requirements for the requested streaming route can be satisfied, adding a routing table entry responsive to the pre-admission, admitting the requested streaming route, updating the routing table and transmitting a route reply message to an originator if requested content is cached, updating the route request message and forwarding the updated route request message if the requested content is not cached, receiving a route reply message and deleting the pre-admitted routing table entry if a time has expired.
