Making the data plane of a SDN flexible enough to satisfy the various requirements of heterogeneous IoT applications is very desirable for Software Defined IoT (SD-IoT) networking. The network device having programmable data plane provides an ability to add new packet and data processing procedures dynamically to the IoT applications. Previously proposed solutions for adding programmability to the SDN data plane provide extensibility for packet forwarding operations for new protocols, but IoT applications need more flexible programmability for in-network data processing operations e.g. data aggregation of sensing data from thousands of sensor nodes. Moreover, some IoT models such as OMG DDS, oneM2M, and Eclipse SCADA use publish-subscribe model, which is difficult to represent with the operations of existing message- centric data plane models. We introduce a new in-network data processing scheme for SD-IoT data plane. It defines an event-driven data processing model that can express various in-network data processing cases in the SD-IoT environment. It also proposes a language to program the data processing procedures using the model, and presents a flexible data plane structure that can install and execute the programs at runtime. We demonstrated flexibility of the proposing scheme with sample programs for some example SD-IoT cases.
Modern networks not only forward traffic, but also perform a variety of processing operations on packets (e.g., content inspection, transcoding, QoS scheduling). Such data plane operations cannot be easily coordinated in the current Internet architectures since there is no explicit policy support for packet processing services. As more diverse systems and protocols are deployed in the next-generation Internet, this problem becomes increasingly challenging. In our work, we propose a novel policy enforcement system for data-path functions in the next-generation Internet. Using a formalism to represent policies and automated planning tools, connection request can be adapted to meet the policy requirement of the domains they traverse. We present the theoretical foundations of this approach as well as a prototype implementation based on our network service architecture. Our results show that this approach is an effective solution to enforcing policies relating to the date plane of networks.
A key feature of Software Defined Network is the decoupling of control pane and data plane. Although delivering huge benefits, such a decoupling also brings a new risk: the data plane states (i.e., flow tables) may deviate from the control plane policies. Existing data plane testing tools like Monocle check the correctness of flow tables by injecting probes. However, they are limited in four aspects: (1) slow in generating probes due to solving SAT problems, (2) may raise false negatives when there are multiple missing rules, (3) do not support incremental probe update to work in dynamic networks, and (4) cannot test cascaded flow tables used by OpenFlow switches. To overcome these limitations, we present RuleChecker, a fast and complete data plane testing tool. In contrast to previous tools that generate each probe by solving an SAT problem, RuleChecker takes the flow table as whole and generates all probes through an iteration of simple set operations. By lever- aging Binary Decision Diagram (BDD) to encode sets, we make RuleChecker extremely fast: around 5 χ faster than Monocle (when detecting rule missing faults), and nearly 20 χ faster than RuleScope (when detecting both rule missing and priority faults), and can update probes in less than 2 ms for 90% of cases, based on the Stanford backbone rule set.
Networks have become an important feature of our day-to-day to life and therefore, user experience is an imperative goal to be achieved by network operators. Load balancing is a method of improving network performance, availability, minimizing delays and avoiding network congestion. In this paper, we study dynamic load balancing to improve network performance and reduce network response time. The load balancer is applied to OpenFlow SDN network's data plane with Opendaylight as the controller. The flexibility of the load balancer is tested by using it on two different network topologies. Results show that the load balancer can improve the overall performance of the network and reduce delay. The main contribution of this work is a load balancing mechanism for SDN centralized controller environments which can be employed at any point in time in a network, for example, before network failure or after link failure, to avoid data plane congestion and link overloading.
A Software Defined Networking (SDN) has been deployed in the current network system. Together with Network Virtualization (NVF), it makes the network become more flexible. The firewall can be implemented in SDN. However, with the limitation of earlier version of OpenFlow protocol used in SDN, the stateful firewall could not be implemented with the SDN standard. The development of OpenFlow enables some features that can be used for implementing the stateful firewall. In this work, we implement the stateful firewall in the SDN switch on the data plane. The Open vSwitch is used. We also evaluate the performance of the SDN stateful firewall. The results show that our SDN stateful firewall can work correctly with small overhead increased in SDN switches.
Recent developments in Internet technology have led to an increased importance of Software-Defined Networks (SDN). Due to advantages of this new network model that controls the network centrally, many service providers and vendors expect that traditional networks should be superseded by SDN. However, because of their centralized nature, they are vulnerable in terms of reliability and fault-tolerance issues both on data and control planes. Thus, developing such a fault-tolerant SDN design is quite important. In this study, fault tolerance on the data plane is targeted by considering various network and performance measurements. In the experiments, the impact of the topology size, frequency of packets, and the number of flows in the current route on the recovery time is tested. Moreover, local and global recovery approaches are compared.
In order to solve physical nodes virtualization, the industries introduce the system virtualization technology. Through we in-depth research on the shortcomings of virtual routers which implement by the system virtualization technology, we find that competition of I/O resources greatly affect the overall performance of the virtual router. This paper presents an improved mechanism for virtual router data plane. The program adopts rewrite packet header processing mechanism to optimize packet processing path in the virtual router forwarding plane and reduce the I/O resources time occupied by forwarding a message, which thereby reduces the competition of I/O resource among the virtual router data planes. Through the analysis of its performance, the program not only meets the basic principles of virtual routers, but also has much advantages in forwarding the packet rate and resource utilization.
The programmability of the network data plane has become one of the most desirable features within the context of software defined networks, with P4 serving as a domain-specific language for defining data plane processing. In this work, we are motivated to address the challenges of mapping a P4 defined data plane to a heterogeneous programmable hardware architecture consisting of both a CPU and a GPU, which includes a salient parallel SIMD architecture for processing network flows. We first design a toolset that can be used to map a P4 program onto the proposed architecture. We then optimize the GPU kernel designs for “match-action” primitives and present latency-hiding techniques to reduce the overheads of CPU/GPU communication. In addition, load balancing is investigated to maximize the utilization of CPU and GPU resources. Our toolset and optimizations allow a P4 program to render promising performance on the given heterogeneous architecture. Specifically, the experimental results collected on our prototype systems show that the automatically configured GPU kernels achieve scalable lookup and classification speeds with 420 million IP lookups per second, and more than 60 million classifications per second (for 4K firewall rules).
In recent years, a new concept of network architecture with control/data plane separation is introduced to the future network, which can effectively improve the mobility robustness and reduce the handover failure by providing the data plane services under the umbrella of a macro cell coverage layer. However, in the ultra dense network, frequent data plane handovers would still introduce huge signaling exchanges and latencies. In this paper, we propose a universal predictive mobility management scheme for urban ultra-dense networks to speed up the data plane handover process. We utilize the probability suffix tree model to save and analyze the transition relationships between small cells in terms of variable markov chains, and pre-configure a cluster of small cells with larger handover probabilities for the users. To accommodate different versions of the users, a compatible network-controlled predictive mobility management procedure and an advanced user-autonomous predictive mobility management procedure are proposed to support the proposed predictive mobility management scheme. The simulation results show that the proposed scheme can significantly improve the prediction accuracy with a lower redundant configuration cost and can effectively speed up the data plane handover process compared with the traditional mobility management.
With the advent of P4-specific programmable data plane (PDP), network functions (NFs) can be offloaded into the PDP to achieve high performance guaranteed by hardware. Meanwhile, CPU powers consumed by NFs can be released to user applications. However, as more and more NFs can be offloaded, several problems rooted inside the PDP severely hinder it from facilitating this offloading trend. 1) The existing PDP provides the exclusive data plane abstraction where different NFs cannot operate the same data plane. 2) The PDP is hardly able to deploy NFs in a “hitless” manner. In this paper, we propose HyperVDP as a high-performance data plane hypervisor to provision non- exclusive abstraction and uninterrupted reconfigurability on the P4-specific PDP. To achieve virtualization, we design several innovative techniques to equally express functions of all programmable elements in the P4-specific PDP. We implement the prototype of HyperVDP on different target platforms, and evaluate different target-based prototypes by comparing with their counterparts. Results show that BMv2-target HyperVDP averagely prevails over its counterpart 2.5× in performance and 4× in resource efficiency. DPDK-target HyperVDP performs comparably to its counterparts while offering virtualization features which neither of its counterparts could provide.
