-The rapid development of the internet and infrastructure growth requires high bandwidth availability to meet the company's operational end. In balancing the necessity bandwidth with the rent access cost require calculation model efficiency service delivery bandwidth. Input data bandwidth, gained by using the inbound and outbound data. To determine the bandwidth requirement, one of the approach used are Fuzzy Logic. Criteria for determining the bandwidth requirements are processed using a modeling-based Adaptive Neuro Fuzzy Inference System (ANFIS). The resulting output data will determine the bandwidth requirements to be upgrade or not. In this study I have been using several membership functions to produce the alleged level closest to the real conditions. Resulted the smallest error contained in the Hybrid method with type MF trapmf to generate error = 6.0182e-06.
