Software Defined networking (SDN)
This document provides an overview of Software Defined Networking (SDN) and OpenFlow. It defines SDN as separating the control plane from the data plane, allowing for centralized control of network traffic and more flexible programming of network behavior. OpenFlow is introduced as an open standard protocol that allows programming of network forwarding behavior by defining flows through flow tables on switches. Key benefits of SDN like efficiency, agility, scale and innovation are discussed. Components of an OpenFlow network including controllers, switches, and the secure channel are also outlined.
SDN Fundamentals - short presentation
The document provides an overview of software-defined networking (SDN) fundamentals, including:
- In traditional networks, the control plane and data plane are logically coupled within each network device, whereas SDN separates these planes and centralizes the control plane in an SDN controller.
- The SDN controller holds the entire network description as a graph and can perform optimization calculations. It programs flow entries into forwarding devices using the OpenFlow protocol.
- OpenFlow defines a standard interface that gives access to the forwarding plane of network switches or routers. It separates the data and control planes and allows the control logic to be implemented separately in the SDN controller.

Introduction to Software Defined Networking (SDN)
Here are the key steps:
1. Kill any existing controllers running on the system
2. Clear out any existing Mininet topology using mn -c
3. Start the Ryu OpenFlow controller by running:
ryu-manager --verbose ./simple_switch_13.py
This starts the Ryu controller with the simple_switch_13.py application, which provides basic OpenFlow switch functionality. The --verbose flag prints debug information from the controller. We have now initialized the SDN environment with Ryu acting as the controller.
Introduction to OpenFlow
OpenFlow is a standard protocol that allows separation of the control plane from the data plane in network devices like switches. It defines communications between controllers and switches. Controllers install flow entries in switches' flow tables which determine how traffic is forwarded. This allows centralized control over distributed switches using protocols like OpenFlow to program their forwarding behavior.

Wsn routing protocol
The document discusses routing challenges and protocols in wireless sensor networks (WSNs). It covers flooding, hierarchical routing protocols like LEACH, data-centric protocols like directed diffusion, and negotiation-based protocols like SPIN. It also discusses resource constraints in WSNs like limited energy and the need for routing protocols to be energy-efficient. Unique characteristics of WSNs like dynamic topology and varying node densities present new challenges for routing protocol design.
Software-Defined Networking (SDN): Unleashing the Power of the Network
It goes without saying that cloud computing has dramatically reshaped the information technology services landscape. Virtualization is unleashing the power of commodity-based technology and open source communities are building new applications and services at an astonishing rate, but networking has lagged behind compute and storage in virtualization and automation. We’ve become accustomed to specialized networking silicon, complex operating systems and highly distributed control planes. For the most part, we’ve accepted the model along with its high costs.
All that is changing! New protocols such as OpenFlow are freeing the network control plane from proprietary operating systems and hardware platforms. We are entering a new era where customers control the features – and release schedules – of new, open networking applications that address the needs of the mega-scale world.
A lot of work is required to realize the potential of Software-Defined Networking (SDN), where we can enjoy the benefits derived from “software automating software.” This talk will examine some of the history that led us to the point where current networking architectures are no longer viable for cloud computing at mega-scale. We’ll take a look at the basics of SDN and some of its key elements – OpenFlow, network virtualization, and orchestration – along with some of the initiatives and companies that are setting the stage for the next generation of networking.
SDN, OpenFlow, NFV, and Virtual Network
This document discusses SDN (Software Defined Networking) concepts including controllers, applications, and components. It provides brief descriptions of popular open source SDN controllers like NOX, POX, Ryu, Floodlight, Opendaylight, and ONOS. It also summarizes common SDN applications like routing protocols and security applications. Key SDN characteristics and benefits are outlined as well.
Network function virtualization
Network functions virtualization (NFV) is a network architecture concept that uses the technologies of IT virtualization to virtualized entire classes of network node functions into building blocks that may connect, or chain together, to create communication services.
Software defined network
This presentation of mine gives basic idea about SDN, use of SDN in different fields, cause of evolution of a new network architecture, openFlow standard and Architectural components.
Introduction to SDN and NFV
This slide covers evolution of Networks, SDN Concepts, Various Controller available in the market and Use Cases.
Mininet introduction
Mininet Emulator is tool used in Software Defined Network (SDN) Experiments. By using Mininet you can create simple as well as complex topologies.
CCNA
The document provides an overview of the CCNA certification and covers topics like internetworking, IP addressing, routing protocols, Cisco IOS, and more. It begins with an introduction to computer networks and protocols. Then it discusses the OSI reference model, IP addressing fundamentals, routing protocols like RIP, IGRP, EIGRP and OSPF, Cisco IOS configuration, and IP routing. The document serves as a study guide for CCNA exam topics at a high level.
5G Network Architecture and Design
5G network architecture will include new functional blocks and interfaces defined by 3GPP. There are several options for deploying 5G, including standalone and non-standalone modes. When adding 5G to an existing multi-RAT site, backhaul capacity will need to be increased to at least 10Gbps to support 5G capabilities like massive MIMO and wider channel bandwidths. Migration from EPC to the new 5G core (NGCN) will require interworking between the networks during transition.
SDN & NFV Introduction - Open Source Data Center Networking
This document introduces software defined networking (SDN) and network functions virtualization (NFV) concepts. It discusses challenges with traditional networking and how SDN and NFV address these by decoupling the control and data planes, centralizing network intelligence, and abstracting the underlying network infrastructure. It then provides examples of open source SDN technologies like OpenDaylight, Open vSwitch, and OpenStack that can be used to build programmable software-defined networks and virtualized network functions.
DSR Protocol
The Dynamic Source Routing protocol (DSR) is a simple and efficient routing protocol designed for use in wireless ad-hoc networks without existing infrastructure. DSR allows networks to self-organize and self-configure. It uses two main mechanisms: route discovery determines the optimal transmission path between nodes, while route maintenance ensures the path stays optimal and loop-free as network conditions change.
Overlay networks
Overlay networks are virtual networks built on top of existing networks that add additional layers of indirection. There are several types of overlay networks including caching, routing, and security overlays. Two examples of anonymous communication networks are ACN and I2P. I2P uses "garlic routing" which involves layered encryption, bundling multiple messages together, and ElGamal/AES encryption. It has a distributed, self-organizing design and uses short-lived, unidirectional tunnels to provide anonymity through its network.
OpenFlow
This document provides an overview of OpenFlow including:
- The need for OpenFlow to facilitate network innovation and programmability.
- How OpenFlow separates the control and data planes through an open interface.
- The basic components of an OpenFlow switch including flow tables, action sets, and packet processing.
- How OpenFlow controllers communicate with switches through secure channels to program flow entries.
- A demonstration of the packet flow through an OpenFlow network from switch to controller.
- Details on OpenDayLight and Mininet which are commonly used for OpenFlow demonstrations.
Routing in Mobile Ad hoc Networks
This document summarizes several reactive routing protocols for mobile ad hoc networks (MANETs). Reactive protocols create routes only when needed by a source. Dynamic Source Routing uses route requests and replies to find paths, while Temporally-Ordered Routing Algorithm builds and maintains a directed acyclic graph rooted at destinations. Some protocols aim to improve quality of service or support real-time data streams through techniques like bandwidth estimation and mobility prediction. Source Routing with Local Recovery reduces overhead by allowing intermediate nodes to perform local error recovery using route caches when possible.
Why sdn
Software defined networking (SDN) decouples the network control and forwarding functions, allowing the control to be centralized and the underlying network to be abstracted from applications. This provides benefits like centralized management, rapid innovation, and increased network programmability. SDN uses protocols like OpenFlow that define messages between a controller and switches to build flow tables for packet forwarding using matches and actions. SDN is well suited for data center networks where it allows for network virtualization and easier configuration changes.
how to simulate ACI
This document discusses Cisco's Application Centric Infrastructure (ACI) and how to simulate an ACI environment. It defines ACI as Cisco's software-defined networking solution that uses an application-policy based model. It then describes the key components of ACI including Nexus switches, the Application Policy Infrastructure Controller (APIC), and ACI modes. It also explains that the Cisco ACI Simulator is a physical or virtual appliance that simulates an ACI environment. Finally, it provides instructions for accessing the ACI sandbox on the Cisco developer website to simulate an ACI environment without needing dedicated hardware.

SDN Abstractions
The document discusses the need for abstractions in networking to simplify network control and management. It argues that networking currently lacks fundamental abstractions, unlike other fields like programming. Three key abstractions are needed: 1) a flexible forwarding model, 2) a state distribution abstraction through a global network view, and 3) separating detailed configuration. These abstractions form the basis of Software-Defined Networking (SDN) and help address its scalability and evolvability. A Network Operating System (NOS) is also proposed to manage the distributed state and communicate with forwarding elements.

VNFs are software implementations of network functions that run over NFV infrastructure and are orchestrated by NFV orchestrators and VNF managers. A VNF consists of one or more VNF components that have well-defined interfaces and can be deployed, managed, and upgraded independently. The document describes the various states, interfaces, and descriptors involved in the lifecycle of VNF instantiation, scaling, updating and upgrading.
Juniper Unified SDN Technical Presentation (SDN Day ITB 2016)
This document discusses unified SDN and its applications across network domains. It defines SDN as separating the control plane from the data plane and using a network operating system to programmatically control the network. However, it argues this approach is too low-level and not manageable. Instead, it proposes a next-gen service management system that compiles abstract service models into device configurations. This allows for automated, standardized, and flexible service provisioning across virtualized data centers, NFV, access edges, aggregation, and cores.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI support
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
