How taswaruddin007/cse421_project-hsc_networking- works
BBEEN is a Cisco Packet Tracer simulation for securely connecting Bangladesh examination-board sites. The principal workflow is examination personnel communicating across the routed WAN with the NEB, divisional and district offices, printing facilities, and the Emergency Distribution Centre; the same network supports web, DNS, email, and site-specific address assignment. The README documents the topology, routing, and service placement, but no Packet Tracer internals or source excerpts were available, so the graph reflects documented relationships only.
