“…Network Debugger (NDB) is a generalised tracing tool that resembles tcpdump but has knowledge of paths [8]. NDB cannot diagnose performance bugs, but bugs related to the correctness of forwarding (e.g., logical errors, switch implementation errors, packet format errors).…”

Abstract-Software-defined deployments are growing into data center and enterprise network infrastructures. The typical promises of software-defined networks (SDN) are improved time for market, decreased risk and operational costs for services, flexibility and unified management. However, little is known and shared about how to actually manage an SDN network, especially in localising underperforming network paths (what we call "troubleshooting"). We describe a novel approach to ease large network troubleshooting by leveraging SDN features and incorporating distributed monitoring of network traffic. We suggest SDN-RADAR, a tool that can help network administrators understand which is the most likely faulty network link. To the best of our knowledge this is the first troubleshooting solution that combines user-side performance measurements with network data extracted from the SDN controller.

“…OF debuggers allow us to trace packet flow behavior to check whether the network is operating as expected [5]. Nikhil Handigol et al in [78] introduced ndb, a SDN debugger. Their idea was similar to gdb, a debugger for GNU operating system, which changes original control flow without any changes to its semantic.…”

Software Defined Networking (SDN) is an emerging architecture which decouples networks control plane and data plane physically. It makes control plane programmable trough a centralized controller, and builds intelligent and flexible networks. The OpenFlow is one of the most famous SDN protocols, which acts as a southbound interface between control plane and data plane. In this survey, SDN implementation approaches and different southbound interfaces, beside different version of OpenFlow, are introduced. In addition to general architecture of SDN, different wireless architectures are discussed. Here, also potential SDN's applications and research areas including hot topics such as Information Centric Networks, Cloud and datacenters, multimedia, wireless and mobile networks over SDN are reviewed.

“…In particular, the generator configures the switches in the testing SDN to send a truncated copy of transmitted packets to another component of the tool, i.e., the collector module. Observe that the packet tracking mechanism we implemented is similar to the NDB tool described in [17]. However, we generate the packets corresponding to the specified requirements while NDB processes only the regular packets transmitted inside the network.…”

Abstract-To configure, troubleshoot and operate their networks, operators often have no alternatives than relying on error-prone manual procedures. The emerging Software Defined Networking paradigm opens new possibilities for more structured networking methodologies. We argue that provably-effective practices can be borrowed from more developed engineering fields, especially software engineering.In this paper, we propose an adaptation of test-driven software development methodologies to software defined networks (SDNs). To support our methodological guidelines, we propose an expressive requirement formalization language. Further, we describe a prototype tool able to check the compliance of an SDN controller with requirements expressed in the proposed language.Our evaluation of the prototype shows promising results on the practical viability of our approach.
