Introduction
This paper is an overview of some aspects of network architecture. Network architecture is defined as the communication products and services that ensure the various components can work together. I will discuss the different physical LAN topologies and how they work. Lastly, I will discuss several of the LAN Standards such as Ethernet and Token Ring.
Mesh
A Mesh topology is defined at a network where each device is connected to every other device on the network. A mesh topology provides for the best performance and reliability. This is good because if there is a failure in transmission, there are other ways within the mesh for the devices to communicate. There are two types of mesh topologies: full mesh and partial mesh. In a full mesh topology, every device is connected to each device on the network. The full mesh can be very expensive and is reserved for backbone networks. In a partial mesh, some devices are organized in a full mesh scheme. The partial mesh is less expensive than the full mesh. One of the biggest advantages of the mesh topology is fault tolerance. It is also not vulnerable to bottlenecks. On the other hand, the disadvantages of the mesh topology outweigh the advantages. The mesh topology is expense because each device has a physical connection to every other device on the network. It is also difficult to install and manage.
Bus
A bus topology is a multipoint electrical circuit. Bus topology employs a decentralized method of media access control known as carrier sense multiple accesses (CSMA). This enables the attached device to make independent...
