  • nfv based scalable Guaranteed Bandwidth multicast service for software defined isp networks
    IEEE Transactions on Network and Service Management, 2017
    Co-Authors: Hardik Soni, Walid Dabbous, Thierry Turletti, Hitoshi Asaeda
    Abstract:

    New applications where anyone can broadcast high quality video are becoming very popular. Internet services providers (ISPs) may take the opportunity to propose new high quality multicast services to their clients. Because of its centralized control plane, software defined networking (SDN) enables the deployment of such a service in a flexible and Bandwidth-efficient way. But deploying large-scale multicast services on SDN requires smart group membership management and a Bandwidth reservation mechanism with QoS guarantees that should neither waste Bandwidth nor impact too severely best effort traffic. In this paper, we propose: 1) a scalable multicast group management mechanism based on a network function virtualization approach for software defined ISP networks to implement and deploy multicast services on the network edge and 2) the lazy load balancing multicast (L2BM) routing algorithm for sharing the core network capacity in a friendly way between Guaranteed-Bandwidth multicast traffic and best-effort traffic and that does not require costly real-time monitoring of link utilization. We have implemented the mechanism and algorithm, and evaluated them both in a simulator and a testbed. In the testbed, we experimented the group management at the edge and L2BM in the core with an open vSwitch-based QoS framework and evaluated the performance of L2BM with an exhaustive set of experiments on various realistic scenarios. The results show that L2BM outperforms other state-of-the art algorithms by being less aggressive with best-effort traffic and accepting about 5%–15% more Guaranteed-Bandwidth multicast join requests.

  • scalable Guaranteed Bandwidth multicast service in software defined isp networks
    International Conference on Communications, 2017
    Co-Authors: Hardik Soni, Walid Dabbous, Thierry Turletti, Hitoshi Asaeda
    Abstract:

    New applications where anyone can broadcast video are becoming very popular on smartphones. With the advent of high definition video, ISP providers may take the opportunity to propose new high quality broadcast services to their clients. Because of its centralized control plane, Software Defined Networking (SDN) seems an ideal way to deploy such a service in a flexible and Bandwidth-efficient way. But deploying large scale multicast services on SDN requires smart group membership management and a Bandwidth reservation mechanism to support QoS guarantees that should neither waste Bandwidth nor impact too severely best effort traffic. In this paper, we propose a Network Function Virtualization based solution for Software Defined ISP networks to implement scalable multicast group management. Then, we propose the Lazy Load balancing Multicast (L2BM) routing algorithm for sharing the network capacity in a friendly way between Guaranteed-Bandwidth multicast traffic and best-effort traffic. Our implementation of the framework made on Floodlight controllers and Open vSwitches is used to study the performance of L2BM.

  • adaptive Bandwidth reservation and scheduling for efficient wireless telemedicine traffic transmission
    IEEE Transactions on Vehicular Technology, 2011
    Co-Authors: Lu Qiao, P Koutsakis
    Abstract:

    Telemedicine traffic carries critical information with regard to a patients' condition; hence, it requires the highest transmission priority compared with all other types of traffic in the cellular network. The need for expedited errorless transmission of multimedia telemedicine traffic calls for a Guaranteed Bandwidth to telemedicine users. This condition, however, creates a tradeoff between the satisfaction of the very strict quality-of-service (QoS) requirements of telemedicine traffic and the loss of this Guaranteed Bandwidth in the numerous cases when it is left unused due to the infrequent nature of telemedicine traffic. To resolve this complex problem, in this paper, we propose and combine the following two techniques: 1) an adaptive Bandwidth reservation scheme based on road map information and on user mobility and 2) a fair scheduling scheme for telemedicine traffic transmission over wireless cellular networks.

  • Guaranteed Bandwidth allocation and qos support for mobile telemedicine traffic
    IEEE Sarnoff Symposium, 2008
    Co-Authors: Lu Qiao, P Koutsakis
    Abstract:

    Cellular networks have been used in recent years as a testbed for the evaluation of the quality of low-Bandwidth telemedicine traffic transmission. The correct and rapid transmission of telemedicine traffic is of utmost importance, therefore telemedicine video, audio and data cannot be treated similarly to regular traffic, but rather need to be offered absolute priority for transmitting over the wireless channel. On the other hand, if a portion of the Bandwidth is dedicated to telemedicine traffic, this Bandwidth will often be left unused as there is no constant need for transmission of telemedicine traffic in the network. Hence, in this paper we focus on the integration of telemedicine traffic with other traffic types in a cellular network and we introduce new scheduling ideas for the efficient transmission of telemedicine traffic.
