Design elements - Cisco routers

The vector stencils library "Cisco routers" contains 27 router symbols for drawing the Cisco computer network diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A router is a device that forwards data packets between computer networks, creating an overlay internetwork. A router is connected to two or more data lines from different networks. When a data packet comes in one of the lines, the router reads the address information in the packet to determine its ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. Routers perform the "traffic directing" functions on the Internet. A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node.
The most familiar type of routers are home and small office routers that simply pass data, such as web pages, email, IM, and videos between the home computers and the Internet. An example of a router would be the owner's cable or DSL modem, which connects to the Internet through an ISP. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common." [Router (computing). Wikipedia]
The example "Design elements - Cisco routers" is included in the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

"A very important concept in object-oriented design, inheritance, refers to the ability of one class (child class) to inherit the identical functionality of another class (super class), and then add new functionality of its own. (In a very non-technical sense, imagine that I inherited my mother's general musical abilities, but in my family I'm the only one who plays electric guitar.) To model inheritance on a class diagram, a solid line is drawn from the child class (the class inheriting the behavior) with a closed, unfilled arrowhead (or triangle) pointing to the super class. Consider types of bank accounts: Figure 4 shows how both CheckingAccount and SavingsAccount classes inherit from the BankAccount class.
Figure 4: Inheritance is indicated by a solid line with a closed, unfilled arrowhead pointing at the super class." [ibm.com/ developerworks/ rational/ library/ content/ RationalEdge/ sep04/ bell/ index.html]
