Software-Defined Networking (SDN) has emerged as a networking paradigm that can remove the limitations of current network infrastructures by separating the control plane from the data forwarding plane. The implications include: the underlying network state and decision making capability are centralized; programmability is provided on the control plane; the operation at the forwarding plane is simplified; and the underlying network infrastructure is abstracted and presented to the applications. This paper discusses and exposes the details of the design of a common SDN controller based on our study of many controllers. The emphasis is on interfaces as they are essential for evolving the scope of SDN in supporting applications with different network resources requirements. In particular, the paper review and compare the design of the three controllers: Beacon, OpenDaylight, and Open Networking Operation System.
Software Defined Networking has become extremely hot both in academia and industry. Most of the SDN protocol is the OpenFlow protocol in the southbound interface. But bue to different manufacturers may have different understanding to the OpenFlow protocol and lead to the implementation may be different. So OpenFlow protocol conformance testing is becoming more important. This paper first introduces the concept of sdn and the current research situation of openflow protocol conformance testing, and then refer to the open source framework OFTest, use API of OFTest to write test cases for conformance testing. Finally, analyze the relationship between the number of test steps and test time according to the results of the test.
Software Defined Networking (SDN) is new technology over the traditional networks. With the new framework design of SDN, security is a big challenge. Number of attacks can be possible in data plane and control plane in SDN. One of the preliminary attacks in SDN is Denial-of-Service (DoS) attack. Providing security to control plane using traditional intrusion detection system (IDS) to mitigate DoS attack is a challenge. DoS attack in SDN affects performance and behavior of network. Legitimate hosts are not able to communicate with server after creation of DoS attack. This paper aims to detect and mitigates DoS attack in SDN. For detection and mitigation of DoS attack we used two techniques-1) Rule based approach using Snort tool 2) Anomaly based approach using BRO tool. For DoS attack creation we employ Hping3 and Low Orbit Ion Cannon (LOIC) tools. We evaluate the performance of technique using parameters like packet loss, average time and round-trip time. Further work can be extended by reducing false positives and false negatives in IDS. False positives are false alarms generated on normal traffic. Which may help to improve the performance IDS.
To meet the future mobile user demand at a reduced cost, operators are looking at solutions such as C-RAN and different functional splits to decrease the cost of deploying and maintaining cell sites. The use of these technologies forces operators to manage two physically separated networks, one for backhaul and one for fronthaul. To solve this issue, transport networks for 5G will carry both fronthaul and backhaul traffic operating over heterogeneous data plane technologies. Such an integrated fronthaul/backhaul (denoted as 5G- Crosshaul) transport network will be software-controlled to adapt to the fluctuating capacity demand of the new generation air interfaces. Based on a proposed data- and control-plane architecture for 5G-Crosshaul, we propose a frame format common to both fronthaul and backhaul traffic as well as a corresponding abstraction of the forwarding behavior of the network elements. The common frame format and the forwarding abstraction define the information to be exchanged at the southbound interface (SBI) of the 5G-Crosshaul Control Infrastructure (XCI). This paper derives requirements for the SBI from 5G use cases.
Software-Defined Networking (SDN) is revolutionizing data center networks for cloud computing with its ability to enable network virtualization and powerful network resource management that are crucial in any multi-tenant environment. In order to support sophisticated network control logic, the data plane of a switch should have a flexible Flow Table Pipeline (FTP). However, the FTP on state-of-the-art SDN switches is hardware-defined, which greatly limits the advantages of using FTP in cloud computing systems. This paper removes this limitation by introducing software-defined FTP (SDFTP), which provides an extremely flexible FTP as the southbound interface of the SDN control plane. SDFTP offers arbitrary number of pipeline stages and adaptive flow table sizing at runtime by building Software-Defined Flow Tables (SDFTs). Our analysis shows that SDFTP could create 138 times more adaptively sized pipeline stages than the hardware-defined data plane while maintaining comparable performance.
When the Great East Japan Earthquake occurred in 2011, telephone and Internet could not be used in many cases. To achieve network availability in disaster situations, we propose the traffic control system based on SNS information. In order to utilize the data of packet payload obtained from SNS, deeply programmable network (DPN), which is extending SDN as implementing programmable data plane and API (Southbound Interface), is needed. In this paper, we use the FLARE switch, which performs not only the function of OpenFlow but also the traffic classification based on the application, using data plane programmability and the content-based control of the packet payload. By using our proposed system, more flexible network control is achieved.
Prevailing network technologies separate control and data planes embedded within networking devices. Problems with this are expensive maintenance of closed-technology network devices and the inability to enforce coherent network-wide policies. Software Defined Networks (SDN) solves these problems with logical centralization based on open standards that use existing networking equipment. Quality of Service (QoS) mechanisms expose configurable parameters that guarantee network performance. These parameters include minimum and maximum rates, number of queues, queue priority, and burst size and are used to implement Class-Based Queuing (CBQ) scheduling that define classes and their scheduling priority. This study is a continuation of a previous effort that explored QoS mechanisms in an SDN environment with the same Class Profiles and Load Configuration. That study focused on bandwidth performance of QoS mechanisms in an OpenFlow SDN environment and included protocol-based metrics. This study explored the latency performance of QoS mechanisms-based CBQ strategies in an OpenFlow implementation of SDN's Southbound Interface. Mininet was used for cost-effective and repeatable emulation of SDN networks. A network topology with a custom controller was deployed on Mininet. Using QoS configurations, CBQ scheduling was implemented for two main Class Profiles: (1) Basic CBQ based on the "Streaming", "Bursty", and "Catch-All" traffic types, and (2) Source CBQ based on Source IP Address groupings. Enforcement points differentiated each Class Profile at the Leaf Switches and at the Core Switch. These Class Profiles and a No CBQ Class Profile were tested for Latency with an averaged Ping scheme at a maximized Load Configuration. Experiment results were based on averaged Ping Round-Trip Times (RTT) measured from all clients to two servers. Results were subjected to Two-Sample T-Tests with Unequal Variance for statistical significance. The previous study showed that CBQs at Leaves' distributed QoS enforcement had significant performance improvement over CBQs at the Core's traditional centralized enforcement with 2% higher bandwidth for Basic CBQ at Leaves and 30% higher bandwidth for Source CBQ at the Leaves. This study further showed that there was a slight but non-significant difference in Latency at 25.08% lower Average RTT for Basic CBQ at the Leaves and 14.41% lower Average RTT for Source CBQ at the Leaves. This indicated that improved bandwidth performance does not come at the price of Latency.
There is an increasing need of synchronization and clock frequency distribution in core and access networks. Synchronous Ethernet (SyncE) is a technology that is able to distribute clock frequency over Ethernet networks, while keeping scalability and reduced costs. Software-Defined Networking (SDN) is another emerging technology that is changing the landscape of network management by separating the control and data planes and introducing a centralized management architecture, with the goal of optimizing network operations. OpenFlow is currently the most popular southbound interface between the control and data planes in SDN networks. In order to operate SyncE networks under the new SDN paradigm and exploit its advantages, an extension of OpenFlow messages and operations is needed. This paper discusses how SDN and SyncE can interoperate, proposes a set of OpenFlow extensions that are backwards compatible with SyncE equipment, and presents results from a an implementation.
A case for incorporating Software Defined Networking (SDN) concepts in wireless networks has already been proposed in various literature. The main challenge towards its wide adoption remains the level of reliability of a wireless link. This short paper provides a significant step towards addressing this challenge. We show a Software Defined Wireless Network (SDWN) architecture with emphasis on the wireless southbound interface. The specific command primitives required and their descriptions for managing this interface are provided. We finally demonstrate our flow-based virtual pipes for more reliable and QoS sensitive traffic flows.
This work demonstrates a hierarchical control plane architecture for Software Defined Networking (SDN)-based Segment Routing (SR) in multi-domain networks. An orchestrator application, on top of multiple open source SDN controllers, creates a hierarchical control plane architecture using northbound RESTFul APIs of controllers. The orchestrator has control, visibility and traffic engineering capabilities to manage multi-domain SR service creation. Standard southbound interfaces with proper SR extensions are exploited to manage SR tunnels in the MPLS data plane.
