Garantias de QoS em Redes de Transporte 6G: Roteamento na Origem Orientado a Filas de Serviço
Resumo
Este artigo propõe o SPolKA, uma arquitetura para fatiamento de redes de transporte 6G que unifica o roteamento na fonte e o provisionamento de QoS sem estados no núcleo da rede. A solução usa aritmética polinomial para codificar a rota e a política de filas em um único rótulo na borda da rede. Protótipos em P4 usando o emulador Mininet com software switch bmv2, aprimorado com o algoritmo Weighted Deficit Round Robin (WDRR) e switches Tofino comprovam o isolamento de tráfego, métricas de desempenho e migração ágil.Referências
