Previous issue date: 2017-03-15 / Service Function Chaining (SFC) ? um importante campo de pesquisa na ?rea de redes de
computadores, com v?rias propostas de diferentes m?todos de encapsulamento e encaminhamento de pacotes. Os m?todos de encaminhamento de pacotes usados para implementar SFC podem inviabilizar o uso de ferramentas tradicionais de depura??o de rede, o que dificulta a detec??o de erros de configura??o ou poss?veis degrada??es de desempenho em ambientes SFC. Este trabalho apresenta o SFC Path Tracer, uma ferramenta para detec??o de problemas no dom?nio SFC em
ambientes NFV/SDN. Essa ferramenta permite a identifica??o de problemas no dom?nio SFC, atrav?s da gera??o de trace de pacotes e medi??o de atrasos intra-hop a partir de um SFC Path espec?fico. SFC Path Tracer ? agn?stico em rela??o aos mecanismos de encapsulamento e encaminhamento usados para implementar SFC, sendo eficaz na detec??o de grande parte dos problemas em um ambiente SFC. / Service Function Chaining (SFC) is an important research field in networking area with many encapsulation and forwarding mechanisms being proposed. To implement SFC, non-standard forwarding methods are used which break the mechanism of regular network troubleshooting tools, challenging the detection of SFC misconfiguration or performance degradation. This work presents the SFC Path Tracer, a tool for roubleshooting SFC in NFV/SDN environments. This tool enables the identification of problems in the SFC environment by generating packet trace and computing intra-hop delays from a specific SFC path. SFC Path Tracer is agnostic regarding the SFC encapsulation and forwarding mechanisms being effective to detect most problems in an SFC environment.
