Any number of networks can be interconnectedĪnd communicate as long as they all adhere to the same network protocols. If network 2 goes down, router R3 still provides a route between networks 1 and 3. The reason for such redundancy is reliability. ![]() Networks 1 and 3 are directly connected by a router R3. As internetworks grow more complex, each router must make more and more decisions regarding where packets are to be sent.Ī step up in complexity is the case shown in the following figure. A broadband network consists of geographical elements (horizontal dimension) which include 3 distinct parts: Backbone network: Consists of a ring of fibre optic cable connecting different areas of the municipality or region.The ring topology has the advantage to be robust (redundant network) against single fibre cuts or other faults (e.g. ![]() Routers join networks into internetworks and route packets between them based on the addresses of the destination network. Topology refers to the arrangement of physical or logical aspects of your network. In the second case, router R1 connects networks 1 and 2, and router R2 connects networks 2 and 3, thus forming a network made up of networks 1, 2, and 3. In the first case, network 1 and network 2 are joined The second shows a configuration of three networks, interconnected by two routers. The first illustration shows a simple configuration of two networks connected by a single router. The following figure shows the basic parts of a network topology. They also should be able to pass packets to networks that lie beyond the adjacent networks. The routers must be configured to pass packets between two adjacent networks. Two or more networks can be connected together by routers to form larger internetworks. Network Topology is a computer communication system’s structure and arrangement of components. What is Network Topology Network Topology refers to the pattern or arrangement in which network devices and computer systems are interconnected with each other. ![]() The key is to understand your objectives and requirements to create and manage the network topology in the right way for your business. However, the machine cannot function as a router until properly configured, as described Several tasks go into effective network topology management, including configuration management, visual mapping, and general performance monitoring. For LAN and WAN networks, NTM offers a variety of discovery approaches including SNMP (v1-v3), ICMP, VMware WMI, and more. A network topology is the physical and logical arrangement of nodes and connections in a network. From a TCP/IP perspective, a router is any machine that has two or more network interfaces. Network Topology Mapper allows you to establish a topology map, using auto-discovery and consistent network scanning features to help ensure the map accommodates new devices. Routers are the entities that connect networks to each other. There are eight types of topology Mesh, Star, Bus, Ring, Hybrid, Tree, P2P and Daisy chain. Network topology describes how networks fit together.
