Emerging real-time services: optimizing traffic by smart cooperation in the network

Abstract — The rise of new real-time interactive services, in which consumers demand a high subjective quality, makes it necessary to define new network mechanisms that can dynamically adapt to the traffic variations. Cooperation between the different actors is required in order to adapt the traditional network infrastructure to these new traffic patterns while guaranteeing delay requirements. Thus, standardization is needed in order to make cooperation possible. A method for Tunneling Compressed Multiplexed Traffic Flows (TCMTF) is proposed as an update to TCRTP, the current practice defined by the IETF for optimizing RTP flows. Some scenarios have been identified, in which traffic optimization can be deployed, while granting resource usage fairness and good user’s experience. This proposal could be used in different application environments, as operators ’ networks, Internet service providers, long distance transports and game providers.
