Introduction

To connect lots of distant office locations such as those for CloudCrashers, all the office locations must be in a position to access the same network resources. Most of the organizations such as CloudCrashers use Wide Area Network (WAN) to connect remote offices. Additionally, WAN are used to connect Local Area Network (LAN) of different offices.

CloudCrushers Operation

CloudCrushers is a company that provides their customers with software consulting services. The company has 5 offices where 2 are located within the US and 3 outside US. Within the US the company has over 200 employees where some of them need to telecommute. Additionally, the Company has over 200 employees who work in various locations and who telecommunicate in full time. Outside US the company has 360 employees; 150 in India, 10 in Japan and 50 in England.

Modes of Network Connectivity that CloudCrushers need to implement

WAN basic requirements

CloudCrashers need to implement branch/private WAN aggregation with a leased line.

Hardware requirements: The hardware required to implement WAN link is readily available. The major hardware required include; modem, telephone line, satellite, transoceanic cabling, WAN core router, and ISDN adapters (Gifford, 2015).

Software requirements: The main software required to implement WAN is Software Defined Networking (SDN). The aim of SDN is enable network administrators and engineers to respond quickly to the organization requirements through centralized control console.

Telcho services : In leased line the basic requirements are IP routing feature either version 4 or version 6, IP multicast and unicast, Netflow, Quality of Service (QoS), Web Cache Control Protocol (WCCP), multilink PPP (MLPPP), high availability (HA) and Multiprotocol Label Switching (MPLS).

LAN basic requirements

Computer memory 1GB and but the recommended requirement is 2GB. The processor speed is about 2 GHz and the network Cards is 100BaseT. At the workstation memory 1GHz and 2GHz and the RAM is the minimum 1 GB and but the recommended one is 2 GB. Additionally CAT 6 cables and a switch is needed to connect every of the workstation computer

802.11b wireless connectivity

802.11b wireless connectivity is very a powerful 32-bit PCI Card. It offers a transferring date rate of 11Mbps in a wireless LAN environment such as that CloudCrashers. A typical coverage area for wireless connectivity is 100 to 300 meters. The basic requirements are the wireless antennas, wireless routers, and wireless network adapters.

Cost Analysis

The overhead and installation of WANs and LANs is expensive. Implementing of WAN requires a lot of resources although with the advent of cloud and the incorporation of the cloud it is very cheap. The cost of leased lines line connection is usually fixed per month, annual rate or quarterly. The main factors affecting the fee are distance between the points and the speed of the circuit. The costs vary between £300 and £1,300 a month which does not include set-up cost. The installation cost varies between £500 and £40,000 which depends on distance and the circuit size. The installation cost for Wireless network depends on wireless coverage and the number of users the installed cost for about 100 users with a 20 me radius of coverage is about 24,000 dollars. LAN installation cost also depends on the number of users. A workstation with about 200 users the installation cost goes for around 30,000 US dollars (Reed, 2003).
