“…The existing SDX-based frameworks in multi-hop topology are computed the recovery backup path calculation after link failure occurs that resulting in an operational delay to recover the failure quickly and depending on the OpenFlow features. So, the other frameworks proposed the mechanisms [24], [36] that can enable computing the recovery backup path before link failure occur, but they are not applied on multi-hop IXP topology. Therefore, the ELFR mechanism applies the technique that can quickly compute the path before link failure is detected by exploiting the existing mechanism to find the shortest path and reduce the calculation time of the backup path.…”

“…In the SDN environment, the controller calculates before link failure is detected and stores in ternary content-addressable memory (TCAM) switches that cause memory overhead. The existing frameworks [35], [36] proposed the mechanisms that reduce the switch memory overhead by using P4 features, but they are not implemented on multi-hop IXP topologies. So, the proposed ELFR mechanism attempts to reduce the memory overhead by exploiting the P4 features.…”

Internet eXchange point (IXP) is a way to optimize network bandwidth. It enables a platform in the different providers like internet service providers (ISPs) and content delivery providers (CDNs) to share their traffic through a common point. A software defined exchange point (SDX) is an IXP comprising of a programmable deployed software defined network (SDN) switching fabric to enhance the management of their services, but they met the performance issues. The previous studies proposed various mechanisms and frameworks that tackled with these issues, but they don’t overcome overall challenges like link failure recovery for multi-hop-based SDX particularly packet processing delay and switch memory overhead. To cope with these issues, this paper proposed an enhanced link failure rerouting (ELFR) mechanism for multi-hop-based SDX. The objective of the proposed ELFR mechanism is to reduce the delay of packet processing to recover the link failure quickly and improve the path computation while ensuring the switch storage overhead. The present paper is an effort to retrospect and analyze the critical review of existing work for SDX. Furthermore, this paper provides a background of SDX, its components and its applications. Finally, this paper presents and compares the expected results of ELFR mechanism and related work.

“…La iniciativa más popular en este nuevo campo es la programación de procesadores de paquetes independientes del protocolo (P4) [3], [6]- [9]. El impulso del P4 comenzó con la observación de que, si bien en el pasado los conmutadores de red tenían un comportamiento fijo y conocido, hoy en día está surgiendo una nueva generación de arquitecturas de conmutadores de alta velocidad totalmente reprogramables [10].…”

“…El mundo de las redes se ha definido en gran medida por el desarrollo de chips de funciones fijas. Si bien estos dispositivos han sido uno de los medios por los cuales las velocidades de datos han aumentado, esto se ha logrado a expensas de la programabilidad [9].…”

En las Redes Definidas por Software, el protocolo OpenFlow implementa una abstracción de los elementos de red y proporciona flexibilidad al extraer el plano de control de los dispositivos de la capa de infraestructura. OpenFlow posee algunas limitaciones que están relacionadas con la poca flexibilidad del protocolo en su interface hacia el sur, por lo que actualmente se demandan soluciones más robustas. Debido a estas limitaciones, el lenguaje específico de dominio programación de procesadores de paquetes independientes del protocolo (P4) está ganando impulso en el sector académico e industrial. P4 proporciona un conjunto básico de herramientas para que el programador implemente protocolos en el hardware de conmutación. P4Runtime es una API abierta del plano de control de las redes definidas por software de próxima generación; tiene como objetivo solucionar las deficiencias de OpenFlow, proporcionando una verdadera independencia de hardware de conmutación para los operadores y proveedores de servicios en la nube. Los procedimientos para medir el desempeño de las redes definidas por software basadas en la API P4Runtime es un tema de investigación abierto en la actualidad. Este artículo proporciona una descripción técnica general de los protocolos P4 y P4Runtime, destacando sus beneficios. Finalmente, es implementado un procedimiento que permite cuantificar el del desempeño de este tipo de redes considerando métricas de escalabilidad, latencia, utilización de memoria y carga de CPU. Para realizar la evaluación fueron creados varios scripts en el Bash Shell de Linux. Se registró un deterioro significativo en el retardo de la red (ICMP RTT) en ONOS-P4Runtime-BMv2 en comparación con la red REF-SDN-OpenFlow.
