"Video on demand (display) (VOD) are systems which allow users to select and watch/ listen to video or audio content when they choose to, rather than having to watch at a specific broadcast time. IPTV technology is often used to bring video on demand to televisions and personal computers." [Video on demand. Wikipedia]
The network diagram example "VoD architecture in a NVR enviroment" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computers and

The vector stencils library "Cisco LAN" contains 23 symbols of local area network (LAN) devices and equipment for drawing Cisco LAN topology diagrams.
"Network topology describes the layout of interconnections between devices and network segments. At the Data Link Layer and Physical Layer, a wide variety of LAN topologies have been used, including ring, bus, mesh and star, but the most common LAN topology in use today is switched Ethernet. At the higher layers, the Internet Protocol (TCP/ IP) has become the standard, replacing NetBEUI, IPX/ SPX, AppleTalk and others.
Simple LANs generally consist of one or more switches. A switch can be connected to a router, cable modem, or ADSL modem for Internet access. Complex LANs are characterized by their use of redundant links with switches using the spanning tree protocol to prevent loops, their ability to manage differing traffic types via quality of service (QoS), and to segregate traffic with VLANs. A LAN can include a wide variety of network devices such as switches, firewalls, routers, load balancers, and sensors.
LANs can maintain connections with other LANs via leased lines, leased services, or the Internet using virtual private network technologies. Depending on how the connections are established and secured in a LAN, and the distance involved, a LAN may also be classified as a metropolitan area network (MAN) or a wide area network (WAN)."

"Network Mapping Software.
A number of software tools exist to design computer network diagrams / or generate visual maps of networks, servers, storage, services, data centers, and other peripherals. Broadly, there are two types of software tools - those that help create diagrams manually and those that generate them using automated / semi-automated approaches.
Type of Software.
(1) Manual - allows users to design and draw logical and physical topology diagrams by manually placing icons and connections.
(2) Automated - generate topology diagrams / maps by traversing the network and automatically discovering resident devices or by importing network data." [Comparison of network diagram software. Wikipedia]
ConceptDraw PRO is the software for manual design of computer network diagrams. The solutions of the Computer and Networks area in ConceptDraw Solution Park extend ConceptDraw PRO with vector stencils libraries, templates and examples for creating the computer network diagrams.

Network diagram
"A bus network is a network topology in which nodes are connected in a daisy chain by a linear sequence of buses. ...
The bus is the data link in a bus network. The bus can only transmit data in one direction, and if any network segment is severed, all network transmission ceases.
A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic, and the traffic generated by each station has equal transmission priority. Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable simultaneously, they use a media access control technology such as carrier sense multiple access (CSMA) or a bus master." [Bus network. Wikipedia]

Cisco Network Topology. Cisco icons, shapes, stencils and symbols
Any Cisco equipment on the network are named like node. Network diagram topology commonly designed within connected nodes. Cisco icons are worldwide acknowledged and mainly established as standard icons for network diagrams. You may use them loosely, but you may not rework them.
The Cisco Network Diagram shows how signals act on the networked devices, or how data routes on the network from one device to the other. There are number of physical network typologies that engineers use while constructing computer networks.
"Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. Network planning process involves three main steps: 1) Topological design: This stage involves determining where to place the components and how to connect them. 2) Network-synthesis: This stage involves determining the size of the components used, subject to performance criteria such as the Grade of Service (GoS). 3) Network realization: This stage involves determining how to meet capacity requirements, and ensure reliability within the network."
