No Instructor Submission Date 1 ADVANCED NETWORKING TECHNOLOGIES 2 PART A Define VPN technology and its benefits VPN technology is a virtual private network, which encompasses network links across shared internet. VPN technology Play essentials role in securing networks from the unauthorized users. Through the uses of encryption and verification, the VPN system guarantees all the business information remain private and confidence. Multiple companies in different locations can share information between each other without compromising data leakage to the public (Olifer, 2007). Again, the VPN is necessary for any businesses set up regardless of the location and it has various benefits which include; Figure 1 VPN technology The VPN technology allows business to utilize the available public internet in transmitting their data from one point to another which is cheaper and locally available. Traditionally, other forms of communicating networks in a different location such as the use of frame relay systems and leased lines tend to be quite expensive regarding installation, operating and maintenance cost. Additional, the VPN system is flexible and convenient for mobile users. Mobile users can rely on VPN to access and transact any business activities by the use of local internet provider, and finally, the technology is scalable. ADVANCED NETWORKING TECHNOLOGIES 3 Components of VPN In context, The VPN technology is created with different components that enable it to work efficiently. The principal VPN components includes; • Network access server; in remote access of the VPN the network access server is responsible for providing all the tunnel maintenance and setup of the network system. • Firewall; firewall in the VPN it ensures that the data store remains private and confidential from being accessed by the public. • AAA server; this component of the VPN plays an important role by verifying the internet users to access network. Also, its limits users accessibility and track down what the users are doing within the network (Shannon, 2015). Figure 2 VPNs components Characteristics of secure VPN Typically characteristic of secured NPV allows controlling unauthorized users from accessing private resources and data information. However, it should be shared and monitored by the relevant authority effective. Hence, the VPN technology should have the following characteristic; ADVANCED NETWORKING TECHNOLOGIES • 4 Data encryption; all the information transmitted through the public network should be rendered inaccessible to outsiders. • User authentication; all the users must be verified before accessing the network information. • Multiprotocol support; the use of protocol support such as IP and other common protocol is essential. • Address management; the network managements should ensure that all the relevant information stored are kept private and confidential (Cantrell, 2006). ADVANCED NETWORKING TECHNOLOGIES 5 PART B Definition of frame relay and its benefit Frame Relay is a packet switching system WAN protocol for serial traffic information transmission in different endpoint (WAN) and local area network (LAN). However, the frame relay design system is flexible because it allows multiple links to be terminated at the single interface in the routers unlike the point to point links. Importantly, the termination of multiple links in a single interface allows multiple customers connectivity in one line which saves cost of installation and increases profit margin. To optimize the network design connectivity by changing virtual circuit bandwidth and a port connection is usually a software configuration which makes the design customer connection and implementation to be less costly. Virtual circuit and DLCI no. The other stage of design is to establish a permanent connection which is known as permanent virtual circuits PVC which allows reliable data transmission between the connection devices. The system is stable, and data transfers devices can function efficiently. However, for the PVC to be identified in the system the data link connection identifier DLCI must be put in place, and the primary role is to identify virtual circuits in the systems (Henderson, 1999). Figure 3 Virtual circuit and DLCI no. ADVANCED NETWORKING TECHNOLOGIES 6 Frame relay topologies Frame relay network topologies selected in design depend on various factors, such as network traffic and protocol support system. However, the different type of topology layout in the system includes; Frame relay star topology; it helps to reduce numbers PVCs numbers to cut down the cost. While the full meshed topology usually provides a high level of network availability. Figure 4 Frame relay topologies Frame relay address mapping On top of it, for the Cisco router to communicate information through the relay system, it has to trace the DLCI mapping to layer three addresses of the location. Hence, either dynamic or static relay mapping accomplish layer3 address to DLCI mapping in the system. Figure 5 Frame relay address mapping ADVANCED NETWORKING TECHNOLOGIES 7 Configuration of the frame relay Finally, the configuration of frame relay is the final process of the design process. The local management interface put default on a multiple points, and the frame is a point to point. Also, the IP is disabled, and the routes are updated on the interface. The router identifies DLI and ARP are reversed to IP address, and the frame relay mapping is created (Lacoste, 2014). Figure 6 Configuration of the frame relay ADVANCED NETWORKING TECHNOLOGIES 8 Paper summary The context of the security protocol for frame relay paper is to consider the network protection using the frame relay network system in general. First, the frame relay is even broad network services technology. The frame relay uses packet switching criteria to locate logical and physical links layers of the basic telecommunication digital channels. Traditional, the frame relay was applied on the transporting industries for integrated services digital networks commonly known as ISDN systems. Currently, the technology is intensively used in extensive network interfaces. Frame relay does not utilize windowing and other feature included on version X.25 which make it more reliable to access and being applied in the business. Regarding cost, the frame relay is always considered cost friendly as compared to point to point private lines. Typically, the clients who use frame relay services incurred only a fixed local network fees for the connection, unlike the other network services. Frame relay system is an important network technology in the networking atmosphere. Given the frame relay benefits, it also suitable for LAN system connection. Besides, it's cost friendly it’s also performance efficiency. Frame relay technology provides separate virtual networking in a particular location. Importantly, frame relay advancement has led to emerging of modern technologies such as bank ATM and SONET system. Its offers a high-speed data transmission network system in industries for use. Hence, the frame technology is highly applicable. The frame relay incorporated in SMDS interfaces enables multimegabit data easily accessible. Also, the technology provides connection-oriented networking services contrary to the wireless network services. Unfortunate, the frame relay only supports traditional security mechanism system for protection in the SMDS interface (Varadharajan, 1993).
