PASR: An Efficient Flow Forwarding Scheme Based on Segment Routing in Software-Defined Networking

Abstract: Software-Defined Networking provides flexible and efficient network management. However, the limited flow table space lead to many challenges for SDN networks on flexibility and scalability. In order to achieve efficient routing scheme, we propose an efficient flow forwarding scheme based on Segment Routing named PASR to solve SDN switch flow table resource shortage problem. Traditional OpenFlow-based or MPLS-based flow forwarding scheme may lead to performance degradation due to flow-table overflowed or heavy… Show more

“…Much research [2], [10], [13], [16]- [21] has investigated DCN traffic and related flow management challenges either in SDN or other networking paradigms. Most of the proposed solutions in the DCN context take advantage of leveraging the SDN centralized control and the path diversity typically available in such networks.…”

“…Based on the network programmability that is provided by OpenFlow, Huang et al [18] propose a novel segment routing architecture with improved data plane to reduce the overhead of additional flow entries. In addition to optimizing the number of flow table entries based on SDN, some researches [19], [20] have applied several other techniques to reduce the number of table entries, such as segment routing and traffic engineering. Moreover, the entry size is also been considered as a point of optimization.…”
