System Development Life Cycle

2007 DevelopmentIn both one-server or ii-server overture , the cyberspace configuration afoul(ip) dog employ either radio (cable ) or radio set as media transmission However , considering the vast localization principle of policy-making relation offices that argon going to be uniteed , in this , we suggest the call of piano tuner ne iirk . The reason is wireless network either GSM (global systems for mobile discourses ) or CDMA (code member multiple ingress technologies are currently available wide throughout the U .S , which provide by carrier ilk Verizon and Sprint MobileFor one-server network , we place the server in the mid-western fix The smirch suggests that a service provider , a bon ton that carries out telecommunication service in the U .S , leave alone deliver selective instruction transmission (wire less access ) from external location into the server in mid-western . In the server location , we will place an experienced technicians and over-seen by government-employed economistsThe role of wireless access , called wireless VPN (virtual unavowed network ) is beneficial for the resign government since it is the most constitute effective come since the bloom is based on the enumerate of sent and received information instead of fixed periodic charge . In sum , the use of wireless VPN is similarly easy to install and do not require forward-looking equipments at remote locations . In the remote location , we unspoiled need a wireless modem for either GSM /CDMA technologyIn the two-server mode , the situation is somewhat similar to one-server approach . The difference is on that point is a leased suck up inter-group communication between two servers in to synchronize entropy that placed in the two servers . The get of using this approach is the load of server is re duced importantly since it is shared into tw! o servers .

However , two-server approach may bespeak additional cost as the results of additional leased line service that link two server in two locationsIn general , there are many benefits of using wireless VPN access in the development of one-server of two-server approach in the government state proposed communication network as followingFlexibleLow operation and guardianship costsNationwide cover successionEnd-to-end transmissionAvailability of NMS (network Monitoring SystemSecure (L2TP /GRE /IP Sec Tunneling , 3DES ,MD5Integrated InfrastructureImplementationFigure 1 A poseur of One-Server Approach with GSM /CDMA rile In the figure , we assume the use of both GSM and CDMA networks cod to the vast location of state governments offices to be connected . In the carrier s office , there should be DXC (digital cross connect ) to integrate data sent from GSM and CDMA networks . IN the customer troops (state government offices , there should be a server that feed any locations in the state .ReferencesBitpipe (2006a . lucre Design and wariness First Steps .
