The dynamic OSPF routing scheme of optical networks

In recent years, as the development of the remote monitoring, cloud computing, and network coverage, the traffic has led to explosive growth in data flows of the optical network. The department and planning of the original communication network technology is challenging. The increased network congestion, litter and delays are predictable. In order to solve these problems, the academia and industry have proposed many ways¹⁻⁵. Among them, implementing the routing planning for source nodes and target nodes in the optical network, such as the open shortest path first (OSPF) routing protocols, can effectively improve the network resources utilization in optical network. In this paper, to improve the utilization of the network, a dynamic interface awareness OSPF routing which can be applied to the optical network is designed. The dynamic selection of the routing can be implemented when the interface utilization exceeds the specified threshold value by using the low economic cost for the network.
