Researching wan technologies

1 Network protocols Research Point-To-Point (Dedicated), Packet Switched, And Circuit Switched WAN Protocols/Circuits/Types. Define Each Protocol and Describe At Least Two Data Transmission Technologies Associated With the Prot WAN is an information communications network that includes a very wide geographical area and it normally uses transmission mediums, which are offered by common carriers example by telephone companies. WANs connect together LANS as well as other networks to enable computers and users in one area to communicate with computers and users who are in other areas. 1 Types of WAN protocols are point-to-point protocol, packet switched, circuit switched and cell relay.

2 A point-to-point protocol is a common kind of a WAN connection; it establishes a direct connection between network nodes. The point-to-point verifies connections, compresses, transfers after encryption in this manner it provides privacy. PPP is types of a computer networking protocol that offers standards ways to transfer multiprotocol data across point-to-point links. The PPP is designed mainly to link two networks and transfer IP packets between the two links, these links have the capacity to offer instantaneous bi-directional roles, to deliver data packets in a certain order (NoAuthorFound, 2005). The PPP is a good solution to easy connection of different kinds of bridges, hosts and routers. 3 The point-to-point circuits is a service that utilizes the WAN connection that is dedicated and secure to connect two places and it is also known as Private Lines. The Point-to-Point Circuit lets users to uphold their power over their connectivity and to capacitate video, data and voice transmission in several bandwidth configurations. The Multiprotocol Label Switching technology allows data to be transmitted between WAN nodes from point to point via the network no matter the protocol.

2 The Packet Switched protocol is a type of a WAN technology that users share mutual carrier resources. 4 In the packet switching protocol network devices are able to share one point-to-point link to transmit packets from the source to its destination over a carrier network. 2 The packet switching enables the carrier to use its infrastructure more efficiently and the customer gets a much better cost as compared to the point-to-point lines. 5 Examples of the packet switching network are Frame Relay, Asynchronous Transfer Mode, X. 6 25 and Switched Multimegabit Data Services. 7The statistical multiplexing is key as it enables devices to share circuits. 6 The packet switching is more modern when compared to the circuit switching technology.

8 Circuit Switching is types of a WAN switching method that is a dedicated physical circuit is created, upheld and terminated via each communication sessions' carrier network, the circuits are established over a network when demanded and termination takes place when they are not needed anymore. 9 The Integrated Services Digital Network and the Dial-up are examples of the Circuit switching WAN technology. 10The circuit switching technology contains two kinds of transmissions; 3 the data-stream transmissions and the datagram transmissions. The circuit switch operations can be compared to telephone call (Rullan, 2007). It is used to connect one network with another in situations that do not require a permanent connection. 9 The Dial-up internet access uses public switched telephone network to create a dialed connection to internet service providers through telephone lines. The user’s router or computer has an attached modem that encodes and decodes internet protocol packets and also controls information that is transferred into and from the radio frequency signals. 9 The integrated services digital network is communications standards set that simultaneously transmits digital video, data and voice and other networks across public switched telephone network traditional circuits.
