Data centers with millions of virtual end hosts are now the basis for many Internet and cloud computing services. Compared with existing large layer 2 network technologies, Software Defined Networking (SDN) is emerging as an promising solution due to its agile control and flexible management based on the separation of control and data planes. However, the huge number of routing rules needed in switches and the limited efficiency of the centralized SDN Controller are the two main challenges that affects its scalability. Therefore, this paper proposes a novel SDN based large layer 2 network fabric for data centers: SFabric, which highly reduces the number of routing rules and the interactions between the Controller and switches since the paths are constructed on switch level and most of the rules are installed in advance. A prototype is developed and the experimental results prove the good scalability and efficiency of SFabirc.
Networked Control Systems (NCS) are widely used in industrial applications. Ethernet has recently been used as the communication protocol in NCS. Since overcoming faults is crucial in control systems, fault-tolerance in NCS is being extensively investigated. This paper focuses on the fault-tolerance aspect of Ethernet-based NCS at the network fabric level. It proposes a novel architecture that achieves successful recovery from any single link or switch failure. The model was also tested and proved to be fault-tolerant for some multiple failures.
Fault-tolerance is becoming an increasingly crucial aspect of the design of Networked Control Systems (NCSs) in order to mitigate system downtime. However, the introduction of fault-tolerance is typically associated with significant traffic overhead. In this paper, an optimization to an Ethernet- based network fabric fault-tolerant NCS is proposed. The proposed optimization halves the amount of overhead traffic necessary for fault-tolerance while maintaining the same level of robustness. Moreover, based on the same optimization methodology, an expanded model with two in-line cells is presented and subsequently tested. The expanded two-cell model is designed to provide controller-level in addition to fabric-level fault-tolerance. Simulations using OPNET followed the traffic analysis, and proved the models to be fully reliable in the case of a single failure at a time, for both the single-cell model and the expanded two-cell network.
Without fault-tolerance, a single component failure in a Networked Control System (NCS) can cause system downtime and potentially large production losses. Thus, fault-tolerance is fast becoming a key aspect in the design and evaluation of NCS architectures. In this paper, the focus is on the reliability modeling of network fabric level fault-tolerant NCSs. The two main considered fault-tolerant architectures are based on the Parallel Redundancy Protocol (PRP) and the Rapid Spanning Tree Protocol (RSTP) respectively. Additionally, reliability modeling of a simplex architecture, where no fault- tolerance is implemented, is considered as a baseline for comparison of both fault-tolerant architectures. Moreover, a case study is presented to compare the reliability of the fault-tolerant architectures under study using typical industrial parameters. It is shown that the RSTP architecture offers higher system reliability and longer mission time compared to the other studied architectures.
Seamless virtual machine (VM) mobility within and across data centers brings its own set of problems. One of these problems is enabling co-existence of identical or overlapping layer-2 and layer-3 addresses in a single data center network. The motivation for this problem comes from a number of compelling scenarios. These include the need to backup and restore or replicate multi- tier applications that comprise of multiple VMs from one data center to another or within the same data center. This requires significant network reconfiguration costs as IP addresses of replicated VMs may clash with other existing IP addresses in the data center or with other replicas of the same VMs. Similarly, when multiple data centers need to be consolidated through a single data center interconnect, their address ranges may overlap. Lastly, cloud providers need to ensure that various customers can backup and restore their VMs which can have potentially conflicting addresses with other customers' VMs without requiring time consuming network reconfiguration efforts. In this paper, we present Identity - a data center network fabric that enables co-existence of hosts or VMs with identical layer 2 and layer 3 addresses. We use pseudo addresses to uniquely identify each host or VM and employ address resolution and duplicate detection techniques to enable co- existence of hosts and VMs with identical addresses. We leverage the centralized programmable control plane offered by OpenFlow and present the design and implementation of our scheme in Mininet. We provide an experimental evaluation of our scheme and validate that its average latency and throughput performance is as good as a default setup.
Data centers play an important role with the fast growth of cloud computing used in our daily life. Traditional data center networks based on the fat-tree topology have their own drawbacks and limitations which prevent them from providing high performance to satisfy the increasing demand for cloud services. In this paper, we first design a new flexible network fabric for data center networks based on the concept of Software Defined Networks (SDN). Then, we also propose a simple yet efficient route calculation algorithm for this architecture. Simulation results show that the improved SDN-based switch fabric topology can support more hosts, provide more bandwidth and the shortest paths are found in a smaller amount of time.
Considering flexible technologies available nowadays, operating optical networks much closer to their physical capacities is very tempting but necessarily requires efficient network automation. To achieve this, the two main challenges are handling failures, and accurately predicting performance in dynamic environments. We experimentally demonstrate the ability of the ORCHESTRA solution for early detection and localization of failures, to preventively mitigate their impact and thus guarantee smooth network operation. Then, leveraging machine learning for live performance estimation and closed-loop software-defined network control, we demonstrate a fully automated reconfiguration of marginless connections undergoing critical performance variations over 228km of field-deployed fiber.
In the multicore era, on-chip network latency and throughput have a direct impact on system performance. A highly important class of communication flows traversing the network is collective, i.e., one-to-many and many-to-one. Scalable coherence protocols often leverage imprecise tracking to lower the overhead of directory storage, in turn leading to more collective communications on-chip. Routers with support for message forking/aggregation have been previously demonstrated, supporting such protocols. However, even with the fastest possible designs today (1-cycle routers), collective flows on a k×k mesh still incur delays proportional to k since all communication is across the entire chip. As k increases across technology generations, the latency of these flows will also go up. However, the pure wire delay to cross the chip is just 1-2 cycles today, and is expected to remain roughly invariant. The dependence of message delays on k arises due to the requirement to latch messages at every router. In this work, we remove this requirement.We design a network fabric that enables messages to (1) dynamically create virtual 1-to-Many (multicast) and Many-to-1 (reduction) tree routes over a physical mesh, (2) get forked/aggregated at nodes on the tree, and (3) traverse the tree - all within a single-cycle across each dimension. For synthetic 1-to-Many/Many-to-1 flows, we demonstrate 76/82% reduction in latency, and 1.6/2X improvement in throughput over a state-of-the-art NoC with 1-cycle routers and support for collective communication. Across a suite of SPLASH-2 and PARSEC benchmarks, full-system runtime and energy is reduced by 14% and 50% for a limited-directory protocol.
A testbed for investigation of heterogeneous and reconfigurable data network fabrics supporting a parallel DSP computational accelerator is described. The DSP processors are large-grained processors (Analog Devices SHARC DSPs), with a variety of parallel DSP array architectures possible. The network fabric is intended to be reconfigurable (within a rich but necessarily limited set of structures) to adapt to the needs of a sequence of image processing algorithms being executed (e.g., in a medical image processing environment). The testbed will exploit conventional FPGA components to provide reconfigurable network structures and will exploit commercial high-speed interconnect components emerging for applications such as board-to-board applications. As a computational accelerator, the testbed is intended to be controlled by a host processor, with the host processor cooperating in the definition of the changes in the structure of the network structure as execution of a sequence of image processing algorithms proceeds.
Much of high performance technical computing has moved from shared memory architectures to message based cluster systems. The development and wide adoption of the MPI parallel programming model has hastened this transition. Parallel scaling, however, is frequently limited by the inefficient communication hardware commonly found in commodity based clusters. This paper describes a new communication network (the SiCortex fabric) employed in the SiCortex SC5832 integrated cluster system. The fabric switch and communications controller are integrated with a single-chip multiprocessor node and provides three point-to-point links per node chip. The resulting design provide slow latency, high bandwidth, reliable communication between the 972 nodes of the SiCortex system.
