The invention discloses a topological vector diagram drawing method and system of routing equipment, and relates to the field of the communication. The method comprises the following steps: determining topological port attribute of a topological node, wherein the topological node comprises routing equipment, instrument equipment and equipment wire; rendering the topological node graph according toscalable vector graphic standard; drawing the graphs of the routing equipment and the instrument equipment at a working area of the graphical interface based on the rendered topological node graph; and establishing the topological connection relation of the routing equipment and the instrument equipment through the equipment wire based on the topological port attributes of the routing equipment and the instrument equipment.
