“…While the jitter in LANs is typically small enough to be safely ignored here, in WANs it might have to be considered in the determination of T r ,r . With small jitter, however, the extent of tolerable effects is small, since packets entering the network within the volatile phase (pk 10 ), would, through the artificial delay and small propagation jitter, most probably reach an yet updated downstream replicator, leading to a drop and duplicate free trace (tr 11 ). An optimization of this delaybased method, is to minimize T vol through the incorporation of the network manager's knowledge about the update rates of the involved SDN switches, similarly to [15].…”

“…Scaling and routing of multicast in data-center topologies is investigated in [14]. For multicast-based streaming with multiple simultaneous streams among multiple WAN sites under real-time requirement (3D teleimmersion), [11] introduces an SDN-based control protocol allowing for seamless reconfiguration of the network. Bandwidth and connectivity invariants are maintained using a state-based update procedure.…”

“…Multicast is one network paradigm that tremendously benefits from SDN [10]. Opposed to the distributed creation and maintenance of multicast distribution trees, logical control centralization tremendously reduces complexity and allows for optimized routing, as shown in [11] and in this article. Membership management and control naturally benefit from centralization alike.…”

Updating a network is an essential and continual task in the management of today's softwarized networks. When applying updates on distributed network elements, desired network properties, such as drop-and loop-freeness, might be transiently violated. Although being crucial, update consistency has yet been less considered in network management.In this article, we argue for incorporating the particularities of update consistency into the reconfiguration process of continuous network management. We present a generic management architecture allowing for an appropriate selection of an update mechanism and its parameters based on expected inconsistency effects. We investigate update consistency for the case of multicast routing and show in an extensive analysis why simultaneous dropand duplicate-freeness is not possible. We present an update procedure for multicast routing updates that identifies critical update steps, which are fed back into the reconfiguration process, along with a lightweight approach that allows for the selection of an update strategy, preventing either drops or duplicates. Furthermore, we present an optimization of an existing powerful, but resource-intensive update approach as well as an approach for in-network filtering of duplicates.

Given the exploding growth of video traffic, efficient video distribution is essential to the future Internet. Therefore, how to optimize its networking cost is a critical research problem. In this paper, we introduce Network Function Virtualization (NFV) in conjunction with Software-Defined Networking (SDN) to minimize the cost via joint orchestration of caching, transcoding and routing functions. Specifically, we propose a two-step iterative approach. First, in NFV-based resource allocation phase, we maximize total cache hits by optimally allocating storage and computing resources for a giving routing policy. Second, in SDN-based routing phase, we minimize the networking cost by optimally configuring the routing matrix for a given resource placement. Finally, we analytically prove their iterative repeat converges to the joint optimum. Through extensive simulations, we verify its convergence, and performance gains compared with the optimal solution of either phase alone. By examining numerical results, we obtain some operational guidelines. From the resource allocation aspect, we should allocate more resources to the node with heavier request rate. From the routing aspect, for each node-server pair, the node should split the traffic across multiple paths with identical shortest hops if there are many, or use the shortest path alone if there is only one.

“…In our current research, we aim to leverage SDN support to dynamically control QoS features in multi-stream and multi-party 3DTI. Our recent work [5] has shown that we can drastically improve network bandwidth usage and end-to-end latency in 3DTI streaming over the Internet by taking SDN support at the edges (i.e., inside local network). We replicate and forward the same streams towards multiple participants from the edge switches rather than from the application hosts, which reduces the length of end-toend streaming paths and eventually improves network resource consumption and interactive latency.…”

Software Defined Networking (SDN) has provided configurable access to remote network layer components from application hosts during application run-time. We have successfully enabled SDN switches to reduce network resource consumption and improve streaming latency in multi-party 3D tele-immersive (3DTI) applications. Instead of forwarding the same streams to multiple participants from the application host, local network switches replicate network packets towards multiple forwarding paths. However, due to the variable length of application frames generated from the 3DTI application, maintaining constant packet rates at the network switches cannot guarantee required application frame rates towards different forwarding paths. In this poster, we investigate the problem of guaranteeing application frame rates from the network layer switches. We formulate the problem and sketch a scalable solution using OpenFlow, which is a standard protocol developed for SDN.
