The variety and complexity of current Internet traffic has challenge the Internet Service Providers in providing quality service to the subscribers. Traffic classifications are devised in order to efficiently manage the traffic according to the demand and available resources. In contrast to traditional network, Software Defined Networking (SDN) has a centralized controller in which traffic classifier can take advantage. This paper has identified the state-of-the-art inventions that have been granted patents in the field of network traffic classification, both in traditional network and SDN. The implementation of traffic classification need to adapt; as more traditional network is migrating to SDN. Therefore, the limitation of the current traffic classification has been investigated in order to suggest for its future direction.
