“…If a switch fails, the controller switches from the currently used tree to the complementary tree. [11] proposes a clean-slate approach for multimedia multicasting, where routes between the source and all of the subscribers are computed a priori with the purpose of speeding up the processing of multicast events over SDN framework.…”

Many of the video streaming applications in today's Internet involve the distribution of content from a CDN source to a large population of interested clients. However, widespread support of IP multicast is unavailable due to technical and economical reasons, leaving the floor to application layer multicast which introduces excessive delays for the clients and increased traffic load for the network. This paper is concerned with the introduction of an SDN-based framework that allows the network controller to not only deploy IP multicast between a source and subscribers, but also control, via a simple northbound interface, the distributed set of sources where multiple- description coded (MDC) video content is available. We observe that for medium to heavy network loads, relative to the state-of-the-art, the SDN-based streaming multicast video framework increases the PSNR of the received video significantly, from a level that is practically unwatchable to one that has good quality.Comment: 6 pages, 5 figures, 1 table, First Workshop on Software-Defined Internets of the Future - WSDIF 2014.

“…As described earlier, we argue that the presence of mini-datacenters in central offices (NFV-based COs) as shown in Figure 1 will enable running the MNFs functionalities as VNFs. If such datacenters are not deployed in central offices in the near future, MNFs could either be implemented as middleboxes running next to edge routers or integrated within software routers as switching at the edge is becoming virtual, handled on x86 cores as anticipated by SDNv2 4 .…”

“…Software Defined Networking (SDN) appears to be an attractive approach to implement and deploy innovative multicast routing algorithms in ISP networks [2], [3], [4], [5], [6], [7], [8], thanks to its logically centralized control plane. More specifically, in Software Defined ISP networks, live video streaming applications can benefit from QoS guaranteed dynamic multicast tree construction algorithms [9], [10], [11], [12], [13] that exploit the global view of the network.…”

New applications where anyone can broadcast high quality video are becoming very popular. 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 (NFV) 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 guaranteedbandwidth 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.

“…The proposed replacement is not well defined, and the evaluation of the implemented prototype relies on group membership state being provided by the test orchestration scripts. In Multiflow [5] the authors independently propose another clean slate approach to SDN multicast, and evaluate an implemented controller prototype titled OpenMcast. This work relies on the IGMP protocol for both group management and the determination of multicast routes.…”

In this paper we propose an approach for applying traffic load balancing to multicast traffic through real-time link cost modification in a software defined network (SDN) controller. We present an SDN controller architecture supporting traffic monitoring, group management, and multicast traffic routing. An implemented prototype is described, and this prototype is used to implement shortest path multicast routing techniques which make use of the real-time state of traffic flows in the network. This prototype is evaluated through experimentation in Mininet emulated wide area networks. Evaluation is presented in terms of resulting network performance metrics focusing on the distribution of traffic flows. Our results demonstrate that realtime modification of links costs produces statistically significant improvements in traffic distribution metrics, with an average improvement of up to 52.8% in traffic concentration relative to shortest-path routing. This indicates that SDN enables the use of real-time modification of link cost functions as an effective technique for implementing traffic load balancing for multicast traffic.
