Bandwidth Allocation Scheme using Segment Routing on Software-Defined Network

Nowadays, Internet is the main communication medium but traditional network approach has been difficult to adapt to the fast growing Internet. The emergence of Software Defined Network (SDN) has brought to predict for the solution of this problem. Methods for measuring Quality of Service (QoS) parameters such as bandwidth utilization, bandwidth allocation and delay have been introduced not only for traditional network but also for SDN-based scenarios. Bandwidth allocation is a great significance in various areas of networking. We propose a low-complexity bandwidth allocation algorithm based segment routing for real-time and non-real-time service requests to allocate network resource to ensure the request of services. In this paper, we present available bandwidth allocation scheme based on SDN to provide Quality of Service (QoS) support for various services via experiments under our SDN testbed
