DAIM: a Mechanism to Distribute Control Functions within OpenFlow Switches

Telecommunication networks need to support a wide range of services and functionalities with capability of autonomy, scalability and adaptability for managing applications to meet business needs. Networking devices are increasing in complexity among various services and platforms, from different vendors. The network complexity is required experts’ operators. This paper explores an introduction to networks programmability, by distributing independent computing environment, which would be demonstrated through a structured system named DAIM model (Distributed Active information Model). In addition it seeks to enhance current SDN (Software-Defined Networking) approach which has some scalability issues. The DAIM model can provide richness of nature-inspired adaptation algorithms on a complex distributed computing environment. The DAIM model uses a group of standard switches, databases, and corresponding between them by using DAIM agents. These agents are imposed by a set of network applications, which is integrated with a DAIM model databases. DAIM model also considers challenges of autonomic functionalities, where each network’s device can make its own decisions on the basis of collected information by the DAIM agents. The DAIM model is expected to satisfy the requirement of autonomic functionalities. Moreover, this paper discussed the processing of packets forwarding within DAIM model as well as the risk scenarios of the DAIM model.
