<p>[PROBLEMS TO BE SOLVED] A subject matter is to understandably make one drawing for a logical structure diagram and a physical structure diagram. [MEANS FOR SOLVING THE PROBLEMS] A physical connection between a router (10) and a switch (11) is expressed by drawing a connecting line (A) from circles (outer circles) indicative of the router (10) and the switch (11). By connecting between an outer circle and an intermediate circle/an inner circle with connecting lines, a logical connection between the router (10) and the switch (11), and one inside the switch (11), can be expressed.</p> |
