Software Defined Networking (SDN) is the new paradigm in computer networking industry which changes the present distributed architecture to a centralized one. The three main components of this centralized architecture are Openflow controller, Openflow channel and Openflow switches. Openflow controller is the centralized controlling unit which communicates with openflow switchies via openflow channel according to Openflow protocol specifications. OpenFlow enabled/only switches are the back bone of Software Defined Networking architecture. OpenFlow controllers writes the packet processing parameters necessary to match with an incoming packet and actions to be taken for a packet type in to the flow tables of an Openflow switch. Openflow protocol does not mandate to use any specific algorithm to search for matching flows in the flow tables. Here we analyzes the performance of 4 data searching algorithms and propose an adaptive algorithm considering load factor also as a parameter to reduce the searching time.
Openflow is one of the most important and popular next generation internet structure and technology. Its thought of “software decide network” makes dispatch of controller and date layer. Controller uses the openflow protocol to communicate and control the openflow switch to generate flow table, thus to achieve the centralized control of the whole network. OpenRoads is the framework about the wireless Openflow environment. It successfully apply the thought of SDN on the wireless mobile environment. As a propose to improve the performance and quality of the OpenRoads, The new embedded Openflow-MPLS(EOF- MPLS) is presented. An important technology key point is that both traditional MPLS and Openflow support the thought of separation between controller and date layer which makes a solid foundation for the new EOF-MPLS. EOF-MPLS offered forward equal class(FEC), Label distribute Protocol(LDP) to improve the efficiency of the nodes forward. It makes tight coupling with Openflow structure and support the QoS and traffic engineering. At last an entropy is came up with to assess the communication effectiveness of the EOF-MPLS to the OpenRoads.
Software defined networks are poised to dramatically simplify deployment and management of networks. OpenFlow, in particular, is becoming popular and starts being deployed. While the definition of the "northbound" API that can be used by the new services to interact with an OpenFlow controller is receiving considerable attention, the traditional, "southbound", API that is used to program OpenFlow switches is far from perfect. In this paper, we analyze the current OpenFlow API and its usage in several controllers and show semantic differences between the intended and actual use. Thus, we argue for making the OpenFlow API clean and simple. In particular, we propose to mimic the process that exists in the Python community for deriving changes that result in a preferably only one, obvious way of performing a task. Toward this end, we propose three OpenFlow Enhancement Proposals: i) providing positive acknowledgment, ii) informing the controller about "silent" modifications, and iii) providing a partial order synchronization primitive.
The new software defined networking (SDN) paradigm advocates separating the data plane and the control plane, making network switches simple packet forwarding devices and leaving a logically-centralized software to control the behavior of the network. SDN introduces new possibilities for a centralized network management and configuration. The main benefit is having the programmability of the forwarding tables according to the needs of the applications. Therefore, efficient and effective management of network resources becomes even more crucial in providing effective control plane functionality to the applications. OpenFlow standardization efforts at the Open Networking Foundation resulted in an OpenFlow Configuration (OFConfig) specification to address the management of resources in networks with OpenFlow-enabled switches. We report the implementation of an intuitively easy to use interface for the OpenFlow-capable logical devices as managed resources in a SDN.
The dependable network is needed to enable constantly communication ways since recent disaster such as the Great East Japan Earthquake. To ensure communications, satellite communications have been utilized. However, satellite communications have low throughput which is 60~2000 kbit/s and large time delay which is estimated as almost 240 ms in one way in the case of a stationary satellite. On the other hand, Software Defined Network (SDN) is garnering attention for flexible network building and network faults detection. OpenFlow is one of the realizing ways for SDN, and OpenFlow system is composed of the controller and the switch. The fusion network which is composed of satellite communications and SDN is expected for the wide-area dependable network. In particular, OpenFlow channels for network management are essential, and the deployment of satellite communications on OpenFlow channels is effective to ensure communications. The network scale of OpenFlow network on satellite communications is evaluated using the Flow-mod message which is essential to manipulate the network from the controller. On complete graph with 15 nodes as cities at Toyama prefecture, the controller can send Flow-mod messages to all switches within 210 s. Therefore, the OpenFlow network on the satellite communications is realizable for the dependable network on regional area.
The communication security issue brought by Energy Internet is of great importance and should not be ignored in backbone optical networks which is undergoing the evolution toward software defined networks (SDN). With the aim to solve this problem, this paper conducts deep analysis into the security challenge of OpenFlow based optical networks under energy internet environment and proposes a so-called lightweight security signaling scheme of OpenFlow controlled optical networks for Energy Internet. The proposed scheme makes full advantage of current OpenFlow protocol with some necessary extensions and security improvement, by combining digital signatures and message feedback with efficient PKI (Public Key Infrastructure) in signaling procedure of OpenFlow interaction. Thus, this light-weighted security signaling procedure is also designed in detail to make sure the end-to-end trusted service connection. Simulation results show that this proposed approach can greatly improve the security level of large-scale optical network for Energy Internet services with better performance in term of connection success rate performance.
Software Defined Networking is getting a lot of attention in recent years especially with OpenFlow implementation. Although the Controller centered paradigm brings great advantage to management and visibility, it also may cause some scalability and performance issues on Switch-Controller interface. We propose the "blackhole mechanism" as an alternative to reduce the communication overhead of OpenFlow operation in reactive mode. We also discuss the effect of UDP traffic over the control plane communication. In addition, we describe the problem of matching-rule expiration due to hard timeout regardless the traffic type. Finally, we evaluate the communication overhead through an experimental setup using Pantou OpenFlow switch and POX Controller running L2_learning application.
OpenFlow is a new type of switch model in rapid development. This model supports the control of external policies to network process. Multi-table and multi-item group matching is the challenge in Openflow platform. Three-layer implementation model of Openflow switch is proposed in this paper. Openflow multi-table switching technique based on TCAM is studied, including the model of the multi-table process in Openflow and TCAM performance model. TCAM-based Openflow forwarding performance is analyzed under the above model.
Data centers play an important role in our daily activities. The increasing demand for data centers in both scale and size has led to huge energy consumption. The cost and environmental impact of data centers increases due to large amounts of carbon emissions. One solution to this problem is to intelligently control the power consumption of switches used in data centers. This paper proposes an extension to OpenFlow switches to support different power saving modes. The extension includes defining new messages in Openflow standard and designing an OpenFlow Switch Controller (OSC) that is able to turn on/off switches and disable/enable ports. To prove the soundness of the proposed extension, the OSC has been used to control the NetFPGA based OpenFlow switches in the ECODANE framework. The results presented in this paper can aslo be used by the OpenFlow compliant switches manufacturer or by power aware research community.
This paper presents our developed energy efficient software defined wireless access point with an OpenFlow framework. The developed access point is adaptively powered on/off according to users' traffic conditions by the OpenFlow controller via the OpenFlow protocol. The OpenvSwitch is installed on a commercially available board in the access point to communicate with the OpenFlow controller. Our Experiments shows the detection of traffic flows and switch on/off the network interface. Our experiment confirms that the developed access point with the function of power activation and deactivation is managed based on traffic conditions in the OpenFlow framework. Also, monitoring framework is implemented to detect packet forwarding based on OpenvSwitch logs.
