Publish/subscribe systems on the traditional Internet suffer from poor scalability and high delay in the face of the Internet of Things (IoT) environment. Being customizable, the paradigm of software-defined networking (SDN) provides a chance to establish an IoT-specific network. In this paper, we propose an SDN-based publish/subscribe system named SDNPS, which can construct and fine-tune topic-connected overlays for the sake of disseminating events efficiently and non-redundantly based on a global topology overview. It organizes topics as a Huffman-like topic tree and codes them into binary strings so that filtering and forwarding events can be operated directly on SDN-configurable switches, which helps to reduce end-to-end latency. This hierarchical organization form of topic tree makes it possible to incrementally construct and store overlays, which contribute to reducing the time and space complexity of routing computation. More specifically, it achieves a better tradeoff between load-balancing of the overall optimization objective and the minimal forwarding cost of per-topic overlay.

“…It can also be used to produce dense and real time maps of air and water pollution as well as storing environmental records [21] although that is the main need for distributed cloud. Connection of such heterogeneous devices in the IoT [22] is one the promising benefit of IoT that researchers are already doing their job to address such issues, the first known experimental platform on integrating heterogeneous devices was conducted in centre technologic de Telecommnicacions de Catalunya (CTTC) by [23] in order to integrate wireless/optical networks, distributed cloud and IoT and [24] for IoT devices.…”

“…For the cloud resources (VMs and VNFs), the Cloud and Network Orchestrator communicates with the Compute controller. The Cloud and Network Orchestrator is aligned with the functionalities supported by the VIM in the ETSI NFV architecture [5] and hereink is termed as the SDN integrated IT and Network Orchestrator (SINO) [22]. Figure 6 (b) shows the implemented workflow among the functional blocks constituting the SDN/NFV orchestrator (SINO).…”

“…This provides automatic and unified programmability of the underlying network relying on abstracted data plane information. Thus, the traditional lack of interaction between different network segments and technologies such as mobile and transport layers can be overpassed [5]. Indeed, mobile, fixed and transport layers has traditionally evolved independently which in turn does increase the TCO.…”

Abstract-5G networks will impose network operators to accommodate services demanding heterogeneous and stringent requirements in terms of increased bandwidth, reduced latency, higher availability, etc. as well as enabling emerging capabilities such as slicing. Operators will be then forced to make notable investments in their infrastructure but the revenue is not envisaged to be proportional. Thereby, operators are seeking for more cost-effective solutions to keep their competitiveness. An appealing solution is to integrate all (broadband) services including both fixed and mobile in a convergent way. This is referred to as Fixed Mobile Convergence (FMC). FMC allows seamlessly serving any kind of access service over the same network infrastructure (access, aggregation and core) and relying on common set of control and operation functions. To this end, FMC leverages the benefits provided by Software Defined Networking (SDN) and Network Function Virtualization (NFV). First, we discuss some of the explored FMC solutions and technologies, from both structural and functional perspectives Next, focusing on a Multi-Layer (Packet and Optical) Aggregation Network, we report two implemented and experimentally validated SDN/NFV orchestration architectures providing feasible FMC to address upcoming 5G challenges.
