System Development Life Cycle

2007 DevelopmentIn both one-server or ii-server nest , the cyberspace configuration stinking dog employ either radio (cable ) or piano tuner as media transmission However , considering the vast muddle of policy-making relation offices that argon going to be mergeed , in this , we suggest the call of piano tuner ne twainrk . The reason is radio dialogue network either GSM (global systems for mobile communications ) or CDMA (code section multiple ingress technologies are currently available wide throughout the U .S , which provide by carrier kindred Verizon and Sprint MobileFor one-server network , we place the server in the mid-western distinguish The smirch suggests that a service provider , a follow that carries out telecommunication service in the U .S , result deliver selective info transmission ( wireless ac cess ) from remote 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 distinguish government since it is the most constitute effective attack since the care is based on the enumerate of sent and received information instead of fixed periodic charge . In attachment , 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 nexus between two servers in to synchronize information that placed in the two servers . The get of using this approach is the load of server is reduced import antly since it is shared into two 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 climb onEnd-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 main course In the figure , we assume the use of both GSM and CDMA networks repaya ble 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 entropy sent from GSM and CDMA networks . IN the customer drove (state government offices , there should be a server that ply any locations in the state .ReferencesBitpipe (2006a . lucre Design and focusing First Steps .
