Riordan ManufacturingComputer Network Report______________________________________________________________________________IntroductionRiordan Manufacturing is a global plastics manufacturer that employs 550 people and is headquartered in San Jose, California, having facilities worldwide. The company's mission is to remain the industry leader, while servicing the existing customers as well as expanding. For this,the company will most likely have to overhaul its current infrastructure (Tavangaran, 2016).Importance of Communication ProtocolsProtocol is a common language which two parties agree to communicate in. "Computer networks cannot exist without them." ("What is a Communication Protocol? - Definition from Techopedia", 2016).Now, Riordan Manufacturing is a global company with currently three offices in USA and one office in China (Murillo, 2016). To enable communication among these geographically spread offices we require one common set of protocols for the network.Protocols Selected and WhyWe select Virtual Private Network (VPN) over public Internet under intranet site-to-site configuration for our company's networking requirement.Protocols used will be TCP/IP (Transmission Control Protocol/Internet Protocol), as this is the protocol of Internet and most computers and network devices are capable of communicating inthis (Tyson & Crawford, 2011).We choose this solution as it is cost-effective, is scalable and provides security (by using encryption).

Network ArchitectureEach office's LAN will be configured with a VPN router to serve as endpoints in the VPN architecture. Using their exiting Internet connection, the VPN router will create a per-session 'tunnel' in the public Internet, using which the encrypted user data is encapsulated in tunnel packets and routed as usual on the Internet. The Internet routes these packets as usual and the endpoint computers read the data encapsulated inside the tunnel packets, decrypt it and process it ("How VPN Works: Virtual Private Network (VPN)", 2016).Network Performance ParametersLatencyLatency in general means the time delay it takes for the system to accept an input and produce the desired result, and it effects how usable and enjoyable a system is for users. ("What is latency? - Definition from WhatIs.com", 2016). Latency is a tradeoff in our chosen network. We lose control of or a minimum Service Level Agreement (SLA) on latency as some users in the network may not have sufficient bandwidth. "Latency guarantees are hard to come by because they're hard to implement" ("The Solution - "How do I turn the network I've got into the network I need"", 2016).Response Time Response time measures the time it takes for a request to be processed e.g. you might measurethe response time as the time between when you press the Enter key or click the OK button andthe time the result appears on your screen (Sosinsky, 2009).Again, we do not have a guarantee of response time in our chosen network, due to the wide variety of speed and quality of the underlying Internet routes. We consider this a reasonable tradeoff since the company will primarily be sharing emails, files, and other non-live data.JitterJitter is the variability from the expected values of latency and other network parameters. This is the reason for clicks in audio, artifacts in videos played over a network like the Internet.As mentioned earlier, the company is mainly working with data that is not latency sensitive, thus any jitter is unlikely to have any noticeable effect on user interface (Hruska, 2015).
