Internet Group Management Protocol (IGMP).
Computer and Network Examples
The Internet Group Management Protocol (IGMP) is a communication protocol of the multicast transfer data in the IP networks. IGMP is used by routers and IP hosts for organizing the network devices in groups.
IGMP is a part of IP multicast. IGMP is located at the network level. It is used only on IPv4 networks. IGMP can be used for one-to-many networking applications such as online streaming video and online gaming.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park. It shows the architecture of the network for delivering a multicast service using IGMP. IGMP is used by the client computer and the neighboring switches to connect a client and a local router that implements a multicast. Then between the local and remote routers is used the Protocol Independent Multicast (PIM). With its help the group traffic is routed from the video server to numerous clients of the group transfer.

THREE RELATED HOW TO's:
Network TopologiesWhen describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology.
There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.

Active Directory DiagramIt's no secret that there is a list of skills that every average system administrator should have. And it's important to be able to manage domains via active directory technologies. The best way to keep all the details in mind is to draw a diagram representing users, groups and domains.
This diagram represents an Active Directory Services (Active Directory Domain Services). It can be helpful for system and network administrators to organize a network physical and logical elements (domains, data bases, servers, network equipment, end-user computers etc.) into a secure and logical structure. The logical structure of Active Directory is a hierarchical organization of all network components. The data that is stored in Active Directory comes from some diverse sources. The Active Directory diagram created using ConceptDraw Active Directory Diagram solution. It shows allocating group policies and functions assigned to end users. It helps to plan, manage and maintain the certain user access scenario.

Network Glossary DefinitionWhen talking about engineering, one should define all the terms used, so anybody could understand the topic. Typical network glossary contains definitions of numerous network appliances, types of networks and cable systems. The understanding of basic is crucial for server management, network administration and investigating problems.
The network glossary defines terms related to networking and communications. The most of glossary items has their visual representation in ConceptDraw DIAGRAM v12 libraries of the Computer Network Diagrams solution. This illustration presents a local area network (LAN) diagram. It designed to show the way the interaction of network devices in a local network. The diagram uses a library containing symbols of network equipment, connections and the end-point devices such as network printer, hubs, server, modem and finally computers (PC, mac, laptop). This diagram depicts a physical LAN topology.
