“…While targeting the data plane, proposals such as DevoFlow [416] and Software-Defined Counters (SDC) [432] actually reduce the overhead of the control plane by delegating some work to the forwarding devices. For instance, instead of requesting a decision from the controller for every flow, switches can selectively identify the flows (e.g., elephant flows) that may need higherlevel decisions from the control plane applications.…”

“…Deployment experiences [431] have pointed to a series of challenges stemming from the limited embedded CPU power of current commercial OpenFlow switches. One approach to handle the problem consists of adding more powerful CPUs into the switches, as proposed in [432]. Others have proposed to rethink the distribution of control actions between external controllers and the OpenFlow agent inside the switch [416].…”

Abstract-The Internet has led to the creation of a digital society, where (almost) everything is connected and is accessible from anywhere. However, despite their widespread adoption, traditional IP networks are complex and very hard to manage. It is both difficult to configure the network according to predefined policies, and to reconfigure it to respond to faults, load and changes. To make matters even more difficult, current networks are also vertically integrated: the control and data planes are bundled together. Software-Defined Networking (SDN) is an emerging paradigm that promises to change this state of affairs, by breaking vertical integration, separating the network's control logic from the underlying routers and switches, promoting (logical) centralization of network control, and introducing the ability to program the network. The separation of concerns introduced between the definition of network policies, their implementation in switching hardware, and the forwarding of traffic, is key to the desired flexibility: by breaking the network control problem into tractable pieces, SDN makes it easier to create and introduce new abstractions in networking, simplifying network management and facilitating network evolution.In this paper we present a comprehensive survey on SDN. We start by introducing the motivation for SDN, explain its main concepts and how it differs from traditional networking, its roots, and the standardization activities regarding this novel paradigm. Next, we present the key building blocks of an SDN infrastructure using a bottom-up, layered approach. We provide an in-depth analysis of the hardware infrastructure, southbound and northbound APIs, network virtualization layers, network operating systems (SDN controllers), network programming languages, and network applications. We also look at cross-layer problems such as debugging and troubleshooting. In an effort to anticipate the future evolution of this new paradigm, we discuss the main ongoing research efforts and challenges of SDN. In particular, we address the design of switches and control platforms -with a focus on aspects such as resiliency, scalability, performance, security and dependability -as well as new opportunities for carrier transport networks and cloud providers. Last but not least, we analyze the position of SDN as a key enabler of a software-defined environment.

“…In this case, each router would need to report their average queue length to the RVSDN controller. It has been shown that statistic gathering is an expensive operation on the routers and switches [16]. More research is needed to determine if this method is cost effective.…”

Abstract-Ensuring end-to-end quality-of-service for video applications requires the network to choose the most feasible path in terms of bandwidth, delay and jitter. Quality of service can only be ensured if the paths are reliable -perform to specification per request. This paper makes four contributions to research. First, it presents Reliable Video over SoftwareDefined Networking (RVSDN) which builds upon previous work of Video over Software-Defined Networking (VSDN) to address the issue of finding the most reliable path(s) through the network for video applications. Second, it presents the design and implementation of RVSDN. Third, it presents the experience of integrating RVSDN into ns-3 which is a network simulator used by the research community to simulate and model computer networks. Finally, it presents the results of RVSDN in terms of the number of requests serviced by the network architecture. RVSDN is able to service 31 times more requests than VSDN and MPLS explicit routing when the reliability constraint is 0.995 or greater using aggregation of reliability across network paths.
