WAN TECHNOLOGIES 2 Introduction A Wide Area Network is a collection of networks that interconnects multiple Local Area Networks (LAN) and that communicate with other networks. WAN is a network of networks and in the world, the largest WAN is the internet as it is a collaboration of international networks and people in different countries can collaborate effectively with the use of the internet. A wide area of connections is covered with WAN and it consists of multiple protocol label switching and broadband internet services, and it is a form of data- forwarding technology. WAN is used to speed up connections, control traffic flow, and so on, and with the implementation of WAN in the network the employees of the organization can transfer the data effectively based on the requirement. The working of the employees within the organization can be improved. The common types of WAN technologies that are utilized by the management are, Point-to-point WAN, Circuit Switched WAN, and packet Switched WAN (Alani, 2012). Point-to-point WAN Point-to-point WAN is a kind of network which is helpful for users to transfer data from the local network or system to a remote location. Point-to-point WAN is typically utilized to connect two systems together and between the two systems, the data such as files, documents, text, images, and so on can be transferred based on the requirement. The transferred data between the two devices will be secured from hackers and the confidentiality of the data can be maintained. point-to-point connections can transfer data effectively as it provides the high-bandwidth and low latency. The technologies associated with point-to- point WAN are traditional modem and T carrier lines (Sumi, 2014). Traditional Modem. Traditional modems are utilized to upload and download data from the internet and with the use of a traditional modem the maximum speed of uploading data is 33.6 kbps, and the maximum speed for downloading the data is 56 kbps. In a

WAN TECHNOLOGIES 3 traditional model, the uploading data modem is less compared to the downloading data modem as it samples the analog signal. Examples of traditional modems are V.90 and V.92 these are helpful to transfer data effectively. The bandwidth limitation of a traditional modem is while uploading the data rate analog signal is sampled (Sumi, 2014). T Carrier Lines. T carrier lines are the telephone lines that are utilized to transfer data and voice at high speed and between the nodes in a network, it is utilized to establish physical links. Between the nodes in a network, a dedicated link is created by the T carrier lines and they are costlier. The commercial versions of T carrier lines are T1 and T3, and the data rate of the T1 line is 1.544Mbps and the data rate of the T3 line is 44.73Mbps. The limitation of T carrier lines is by the Mbps low bandwidth is caused (Sumi, 2014). Packet Switched WAN The packet-switched network is one of the methods which uses networking protocols to transfer data. Before transmitting the data the packet-switched network divides the message into packets and between the networks, it is an effective data transfer process. For most modern Wide Area Network protocols packet switching technologies are the part of basis and the protocols include X.25 and TCP/IP (Alani, 2012). X.25. X.25 is a telecommunication standardization that defines the packet level and the physical level of the open system interconnection. Between the data terminal equipment and the data circuit-terminating equipment, X.25 network acts as an interface and the packet mode is operated by it. The connect-mode network services are utilized by X.25 network services and one or more virtual circuits are supported by it. The bandwidth limitation of X.25 technology is the low data rate offered by it (Alani, 2012). Frame Relay. Frame Relay is one of the packet-switching technology and through a digital network it transfers data at high speed. During the transmission period an exclusive collection is established by frame relay and at the end of transmission error checking is

WAN TECHNOLOGIES 4 performed by frame relay. It provides a more effective transmission schema and the bandwidth limitation of the Frame Relay is the technology is not suitable for transmitting sensitive data as it provides a low data rate (Alani, 2012). Circuit Switched WAN Circuit switching is one of the WAN network methods which is utilized to establish a dedicated communication channel. While establishing the connection circuit switching network resources are divided into pieces and between the sender and receiver, a dedicated path is established in circuit switching. Without any delays, the data can be transferred effectively in circuit switching, an example of circuit switching is the telephone system. The technologies that are associated with circuit switching are data streams and datagrams (Smith, Spearing, 2004). Data Stream. A stream of data is present within the data stream transmission and the addresses checking occurs only once in the data stream. For data communication, the data stream is the simplest method as it establishes the dedicated physical connection. The bandwidth limitation of the data stream is the transmission of data can be lower with its implementation of it (Smith, Spearing, 2004). Data Gram. Individual address frames are present within data frame transmission and this transmission technology is utilized in circuit switching operations, telephone networks, and so on to transfer the data effectively. The users can transfer the data effectively with the use of datagram transmission. The limitation of datagram transmission is the wastage of bandwidth (Smith, Spearing, 2004). Conclusion WAN technologies are helpful for people, organizations, businesses, and so on as it is helpful for transferring data effectively. The different locations of an organization can be connected with the use of WAN technology and are helpful for the employees to collaborate

WAN TECHNOLOGIES 5 effectively. The working of the organization can be improved by sharing the data between multiple users and employees of the organization can provide more productivity with the implementation of various WAN technologies. Organizations and various businesses can do global business and can improve the global market by implementing WAN technologies based on the requirement and the organization can gain a huge amount of profits (Smith, Spearing, 2004).
