Gallery: Network Diagrams¶
Network topology examples: simple LAN, bus topology, star, mesh, and tree.
Simple LAN¶
net_lan.py
import engrapha_notes as en
import engrapha_diagrams as ed
net = ed.NetworkDiagram(width=480, height=180, caption="Fig 9: LAN Deployment")
net.node("inet", "Internet", x=50, y=90, kind="cloud")
net.node("fw", "Firewall", x=150, y=90, kind="firewall")
net.node("sw", "Switch", x=250, y=90, kind="switch")
net.node("srv", "Web Srv", x=350, y=130, kind="server")
net.node("db", "DB", x=350, y=50, kind="database")
net.link("inet", "fw")
net.link("fw", "sw")
net.link("sw", "srv", label="Gi0/1")
net.link("sw", "db", label="Gi0/2")
en.add(net.as_flowable())
Star topology¶
net_star.py
import engrapha_notes as en
import engrapha_diagrams as ed
net = ed.NetworkDiagram(width=420, height=220)
net.star_topology(
center_id="sw",
center_label="Main Switch",
spoke_ids=["h1", "h2", "h3", "h4", "h5"],
)
en.add(net.as_flowable())
Ring topology¶
net_ring.py
import engrapha_notes as en
import engrapha_diagrams as ed
net = ed.NetworkDiagram(width=400, height=200)
net.ring_topology(["r1", "r2", "r3", "r4", "r5"])
en.add(net.as_flowable())
Full mesh¶
net_mesh.py
import engrapha_notes as en
import engrapha_diagrams as ed
net = ed.NetworkDiagram(width=420, height=220)
net.mesh_topology(["a", "b", "c", "d"], kind="router")
en.add(net.as_flowable())
