Bandwidth management and strategies for improving network speed

All over the world, there are different types of network and also millions of people trying to carry out one two transactions over these network. Often times, data transactions are very slow especially when it involves the internet. There should be some way to manage and increase the speed of data transactions over different networks and the internet inclusive. The aim of this paper is to expose us to the different bandwidth management techniques out there as well as other strategies to improving network speed. Amongst these techniques include Traffic shaping (rate limiting), Scheduling algorithms, Congestion avoidance and there subcategories. This presentation will also give us an overview of the different types of networks of personal area network is one.

A network is a group of devices connected to each other. Networks may be classified into a wide variety of characteristics, such as the medium used to transport the data, communications protocol used, scale, topology, benefit, and organizational scope.

Therefore, computer network, or simply a network, is a collection of computers and other hardware interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a networked. Networks are often classified by their physical or organizational extent or their purpose. Usage, trust level, and access rights differ between these types of networks. Personal area network

A personal area network (PAN) is a computer network used for communication among computer and different information technological devices close to one person. Some examples of devices that are used in a PAN are personal computers, printers, fax machines, telephones, PDAs, scanners, and even video game consoles. A PAN may include wired and wireless devices. The reach of a PAN typically extends to 10 meters.[8] A wired PAN is usually constructed with USB and Firewire connections while technologies such as Bluetooth and infrared communication typically form a wireless PAN.

Local area network
A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as home, school, computer laboratory, office building, or closely positioned group of buildings. Each computer or device on the network is a node. Current wired LANs are most likely to be based on Ethernet technology, although new standards like ITU-T also provide a way to create a wired LAN using existing home wires (coaxial cables, phone lines and power lines).

Fig1. Typical library network, in a branching tree topology and controlled access to resources A sample LAN is depicted in the accompanying diagram. All interconnected devices must understand the network layer (layer 3), because they are handling multiple subnets (the different colors). Those inside the library, which have only 10/100 Mbit/s Ethernet connections to the user device and a Gigabit Ethernet connection to the central router, could be called "layer 3 switches" because they only have Ethernet interfaces and must understand IP. It would be more correct to call them access routers, where the router at the top is a distribution router that connects to the Internet and academic networks' customer access routers. The defining characteristics of LANs, in contrast to WANs (Wide Area Networks), include their higher data transfer rates, smaller geographic range, and no need for leased telecommunication lines. Current Ethernet or other IEEE 802.3 LAN technologies operate at data transfer rates up to 10 Gbit/s. IEEE has projects investigating the standardization of 40 and 100 Gbit/s.[10] LANs can be connected to Wide area network by using routers
