HiQoS: An SDN-based multipath QoS solution

Abstract

123effective guarantees on quality of service. In the process of the development of QoS technology, the Internet Engineering Task Force (IETF) has explored several QoS architectures such as IntServ [1] and Diffserv [2], but none has been successfully and globally deployed. This is partly because these QoS architectures are built on top of a distributed hop-by-hop routing architecture without a global view. Instead of IP QoS and guarantees, overlay QoS for multimedia applications may provide some level of quality of service to improve the multimedia communication on the top of the best services[3][4][5][6][7]. By using fast label switching, Multi-Protocol Label Switching (MPLS) [8] provides a reliable solution to improve QoS performance. However, it is configured statically without real-time reconfiguration ability and adaptability [19].Current QoS solutions, such as IntServ, may cost too much, or cannot provide an end to end QoS guarantee (e.g. DiffServ), or provides only soft and less efficient QoS such as application layer QoS. Software Defined Networking (SDN) [9] provides a possible way to solve these problems and paves the way for new QoS frameworks. SDN is a new approach for computer networking to manage network services with a global view and real time programmability through abstraction of lower level functionality. It separates the control plane and the forwarding plane of the traditional Abstract: Today's Internet architecture provides only "best effort" services, thus it cannot guarantee quality of service (QoS) for applications. Software Defined Network (SDN) is a new approach to computer networking that separates control plane and forwarding planes, and has the advantage of centralized control and programmability. In this paper, we propose HiQoS that provides QoS guarantees using SDN. Moreover, HiQoS makes use of multiple paths between source and destination and queuing mechanisms to guarantee QoS for different types of traffic. Experimental results show that our HiQoS scheme can reduce delay and increase throughput to guarantee QoS. Very importantly, HiQoS recovers from link failure very quickly by rerouting traffic from failed path to other available path.

Quality of Service (QoS) in Software Defined Networking (SDN): A survey

“…The idea is to keep the best-effort traffic on typical shortest paths and maintain a best-effort traffic table while video flows are routed on QoS-rich paths calculated by the proposed formula and maintaining QoS flows table for them. HiQoS application [34] exploits an SDN-based ECMP (Equal Cost Multipath Routing) algorithm, presented in [83], to find multiple paths between source and destination along with using queuing mechanisms to provide bandwidth guarantee for different classes of traffic. It differentiates different types of traffic and provide different bandwidth guarantees to different services through queuing mechanisms on the SDN switches.…”

Beyond 5G: Hybrid End-to-End Quality of Service Provisioning in Heterogeneous IoT Networks

“…A single controller is introduced in each autonomous system for this purpose. HiQoS technique ensures bandwidth guarantees for different traffic classes by using a queuing mechanism over multiple paths between source and destination [9]. To ensure QoS requirements of bandwidth and jitter, a precise bandwidth allocation scheme over multiple paths is proposed in [10], while minimizing the number of active OpenVSwitches in the network.…”

“…Similarly, path P 2 has smaller length than path P 1 , but is longer than path P 3 . Similar network topologies and link parameters have been used in [9], [11], and [13].…”

On SDN-Driven Network Optimization and QoS Aware Routing Using Multiple Paths

“…Jinyao et al [30] proposed HiQoS, a sophisticated SDNbased multipath solution that uses OpenFlow queuing mechanisms to implement multipath forwarding and bandwidth guarantees. The proposal relies on a modified version of Dijkstra's algorithm that considers QoS constraints to compute such multipaths, which are stored in a hash-map.…”
