Escape

Abstract

Mininet is a great prototyping tool which combines existing SDN-related software components (e.g., Open vSwitch, OpenFlow controllers, network namespaces, cgroups) into a framework, which can automatically set up and configure customized OpenFlow testbeds scaling up to hundreds of nodes. Standing on the shoulders of Mininet, we implement a similar prototyping system called ESCAPE, which can be used to develop and test various components of the service chaining architecture. Our framework incorporates Click for implementing Virtual Network Functions (VNF), NETCONF for managing Click-based VNFs and POX for taking care of traffic steering. We also add our extensible Orchestrator module, which can accommodate mapping algorithms from abstract service descriptions to deployed and running service chains.

Network Service Orchestration: A survey

“…Based on the architecture proposed by EU FP7 UNIFY project [149], ESCAPE (Extensible Service ChAin Prototyping Environment) is an NFV proof of concept framework which supports three main layers of the UNIFY architecture: (i) service layer, (ii) orchestrator layer and, (iii) infrastructure layer [23]. It can operate as a Multi-domain orchestrator for different technological domains, as well as different administrative domains.…”

Uma Abordagem de Fatiamento de Rede entre Múltiplos Sistemas Autônomos

“…Caracteriza se o mecanismo de fatiamento de rede pode criar, modificar ou deletar as especifidades e propriedades da fatia de rede sem requerer o gerenciador ou orquestrador do ISP ou AS. Muitas soluções de fatiamento de rede ainda não dão aos usuários o controle sobre suas fatias de rede (CSOMA et al, 2014;LI et al, 2017a;SILVA et al, 2019).…”
