Description
Este repositório disponibiliza os códigos e a arquitetura do TFTG, uma ferramenta de código aberto baseada em hardware programável (switch P4 Tofino). Sua finalidade é atuar como um gerador de tráfego de rede determinístico, capaz de criar tráfego para os protocolos TSN (Time-Sensitive Network) e DetNet com precisão de nanossegundos e alta taxa de transferência (até 1 Tbps). A ferramenta permite que pesquisadores testem e avaliem cenários de redes de comunicação ultra-confiáveis e de baixa latência (URLLC) voltadas para 5G/6G, conseguindo abstrair topologias complexas de rede em um único dispositivo físico. Os dados publicados consistem estritamente em códigos e scripts de desenvolvimento. O repositório inclui: códigos desenvolvidos na linguagem de programação de redes P4 (que definem o comportamento e o pipeline de processamento do switch Tofino), scripts em Python (que operam como interface do usuário para definição de parâmetros) e módulos de pré-processamento responsáveis por gerar as regras de tabelas, configurações de portas e instanciar a execução no hardware. A pesquisa que deu origem aos códigos foi de natureza experimental e focada em engenharia de redes, conduzida integralmente em ambiente de laboratório computacional. Devido ao escopo técnico, o levantamento de dados não envolveu seres humanos, questionários ou entrevistas. A validação prática do software foi feita através da implementação de um protótipo físico utilizando um switch Tofino 1 comercial, o qual foi conectado a um servidor externo utilizando links de 10 Gbps. O desenvolvimento do código foi guiado por testes rigorosos de geração de tráfego para avaliar o desempenho do software. A ferramenta foi submetida a experimentos controlados no laboratório, gerando múltiplas conexões simultâneas com variados tamanhos de pacotes de dados (64, 512 e 1500 bytes). Além disso, os códigos foram testados utilizando dados de traços de tráfego reais originados do projeto externo Deterministic6G ("cross 900mbps 10pps"), garantindo que a ferramenta desenvolvida consiga reproduzir com alta fidelidade o comportamento de aplicações sensíveis ao tempo do mundo real. Os códigos já foram publicados em: https://github.com/intrig-unicamp/TFTG e https://github.com/intrig-unicamp/ (2026-10-09)
