Hierarchical Network Topology
Computer networks can facilitate human work in various fields of education, government, business or other enterprise. On the campus, network computers can help integrate the computers of computers in every department on campus. Computers on corporate networks can connect any manager with subordinates with the computer system. In this post, I will explain how to install the manufacture of computer network with a hierarchical topology. The first is to understand the network topology to done, the timing of this we use a hierarchical network topology. Hierarchical network topology helps the development of computer network on separate layers. Each layer focuses on specific functions, so that we can Determine the Appropriate devices at each layer on a computer network.
Selection of network topology is hierarchical Because Reviews These networks have the advantage that the advantages of the network hierarchy may be expanded / is more developed, topology hierarchical ensuring the availability of the line at the level of the core and distribution switches performance in the core layer and distribution and more reliable (link aggregation) Port security the level of access and regulation at the level of distribution of make the network more secure, consistency between the switches at each level makes so younger management and shared hierarchical design modularity Allows the network without adding complexity. Hierarchical network topology is divide into three layers namely the core layer, distribution layer and access layer. In a hierarchical network, topology of each network layer has the function of each - each work According to a review of Reviews their fields. This is the explanation of the core layer, distribution layer and access layer in a hierarchical network topology.
The core layer; Core layer to the core layer and the spine (backbone) in a computer network that was formed. The position of the core layer in the hierarchy of the network is on the top layer. The core layer is responsible for the traffic in computer networks. The core layer handles the main line to the backbone of the Internet Service Provider (ISP) and Internet networks. The main task of the core layer in the hierarchy of the network is to create a network design with high reliability, doing design for low latency and speed, and so on. Devices that work in the core layer Including core.vad.id machine, BSD-minded combined with Cisco Catalyst L3, a router, a multiplexer and PBX.
Distribution layer; Layer distribution layer is located between the core layer and access layer. Distribution layer helps distinguish the nucleus in the core network with other networks. Distribution layer defines the manufacturing rules for the network, such as routing updates, the summary route, traffic, and VLAN aggregation address. Some devices that are used in the distribution layer that includes the Cisco Catalyst 6509, Nexus 7000, ASA 5500, Layer 3 Switch, Firewall, LAN routers, bridges, routers, VPN access routers and Cisco Catalyst 6009 core layer 2.
Layer access; Supply layer Access layer traffic to the network and perform network control entries. Access layer is very directly related to the computer network users Because the users who use the computer to access the network through a network access layer. Access layer acts as a "gateway" to the network. Access Layer functions include shared bandwidth, switched bandwidth, MAC layer filters and micro-segmentation [NAT / subneting]. Some devices that are used in the access layer that includes Cisco 1900 series integrated services routers, the Cisco 2900 series integrated services routers, the Cisco 3900 Series Integrated Services routers and Cisco 800 series routers.
