SDN-OpenvSwitch

This article will cover some of the basics of OpenVswitch/OVNKubernetes in relation to learning the path that packets take between pods and also how services work.  This article will end with a cheat-sheet on how to use OpenVswitch/OVNKubernetes for troubleshooting purposes. I will give credit to the following

Optimizing resource allocation and routing to satisfy service needs is paramount in large-scale networks. Software-defined networking (SDN) is a new network paradigm that decouples forwarding and control, enabling dynamic management and configuration through programming, which provides the possibility for deploying intelligent control algorithms (such as deep reinforcement learning algorithms) to solve network routing optimization problems in the network. Although these intelligent-based network routing optimization schemes can capture network state characteristics, they are prone to falling into local optima, resulting in poor convergence performance. In order to address this issue, this paper proposes an African Vulture Routing Optimization (AVRO) algorithm for achieving SDN routing optimization. AVRO is based on the African Vulture Optimization Algorithm (AVOA), a population-based metaheuristic intelligent optimization algorithm with global optimization ability and fast convergence speed advantages. First, we improve the population initialization method of the AVOA algorithm according to the characteristics of the network routing problem to enhance the algorithm’s perception capability towards network topology. Subsequently, we add an optimization phase to strengthen the development of the AVOA algorithm and achieve stable convergence effects. Finally, we model the network environment, define the network optimization objective, and perform comparative experiments with the baseline algorithms. The experimental results demonstrate that the routing algorithm has better network awareness, with a performance improvement of 16.9% compared to deep reinforcement learning algorithms and 71.8% compared to traditional routing schemes.

Dans cette vidéo, nous allons voir ce qu'est le Software Defined Networking (SDN) et quels sont les avantages qu'il apporte. Nous verrons également comment les opérateurs en réseaux ont accès à ce type de technologie. Le Software Defined Networking (SDN) est une approche de gestion de réseau qui vise à rendre la configuration et le contrôle des réseaux informatiques plus souples et plus efficaces. Dans un réseau SDN, la logique de contrôle est séparée de l'infrastructure physique du réseau, ce qui permet aux administrateurs de configurer et de contrôler le réseau de manière plus centralisée et programmatique. Le concept clé du SDN est la "programmabilité". Les administrateurs de réseau peuvent utiliser des langages de programmation pour écrire des "règles de réseau" qui définissent comment le trafic doit être acheminé à travers le réseau. Ces règles sont stockées dans un "contrôleur de réseau" central, qui utilise cette information pour configurer les équipements de réseau (tels que les commutateurs et les routeurs) de manière à acheminer le trafic de manière optimale. Le SDN permet aux administrateurs de réseau de configurer et de contrôler leur réseau de manière plus flexible et plus rapide, car ils n'ont pas à se connecter physiquement aux équipements de réseau pour effectuer des modifications. Cela peut également rendre le réseau plus réactif aux changements de charges de travail et de demande de trafic, car il est plus facile de mettre à jour les règles de réseau en temps réel. En résumé, le Software Defined Networking est une approche de gestion de réseau qui permet une plus grande flexibilité et une meilleure programmabilité, ce qui peut rendre la configuration et le contrôle des réseaux informatiques plus efficaces.

Continuing the how real is the decade-old SDN hype thread, let’s try to figure out if anyone still uses OpenFlow. OpenFlow was declared dead by the troubadour of the SDN movement in 2016, so it looks like the question is moot. However, nothing ever dies in networking (including hop-by-hop IPv6 extension headers), so here we go. Why Would One Use OpenFlow? Ignoring for the moment the embarrassing we solved the global load balancing with per-flow forwarding academic blunders1, OpenFlow wasn’t the worst tool for programming forwarding exceptions (ACL/PBR) into TCAM.
