Abstract

This study addresses the network performance problem at Badan Kesatuan Bangsa dan Politik (Bakesbangpol) Kota Tasikmalaya, where staff devices and public guest devices still operate on the same local network path. The existing architecture forms a flat network with one main switch and one main access point, causing traffic concentration and service degradation when the assembly hall is used for public activities. A simulation-based network engineering approach was applied using Cisco Packet Tracer and the PPDIOO lifecycle to redesign the local architecture without interfering with the production network managed by Diskominfo. The proposed solution applies VLAN segmentation to separate staff and guest traffic, adds a dedicated guest access path, and uses inter-VLAN routing to control communication between segments. Observation results indicate that the internet link capacity was approximately 18.85 Mbps download and 4.81 Mbps upload, while the main issue was distribution failure rather than insufficient bandwidth. Simulation results show that the redesigned network successfully assigns different IP subnets and gateways to guest and staff devices through DHCP, proving that logical separation works according to the design. The redesigned architecture is therefore feasible to reduce bottleneck risk, improve network stability, and strengthen access control in support of SPBE implementation.
