Each network provider promotes multi-service integration on a substrate IP network for cost reduction. For continuous optimization of facilities amount or network topology, it is necessary to grasp traffic structure of each service with its variation accurately. This paper proposes a traffic structure analysis framework for service-integrated carrier networks, with an emphasis on improvement of traffic matrix estimation scheme based on Tomo Gravity for estimation accuracy and extensibility for large-scale networks. Performance attributes of prototype software shows feasibility of the proposed scheme on nation-wide service-integrated carrier networks.
