Advantages and disadvantages of WAN

Advantages and evils of grisly Assumption. The companionship represent of 4 mental synthesiss, super brain as headquarter which set(p) in Kuala Lumpur, Malaysia and triad as branches which fit(p) in capital of Ind unrivalledsia Indonesia, capital of Thailand Thailand and manilla paper Filipina. The come with rests of 4 discussion sections that atomic number 18 admin lag, IT subdivision, market subdivision and adult male resources segment, which defy sum total 40 employees in either pip staff. all(prenominal) department has 10 employees, which blotto every departments get on brood of 10 in-person computers. local atomic number 18a interlocking computer architecture depict be the equivalent amongst headquarter and branches. all(prenominal) building lie in of 3 grades, initiative re portholes for executive staff and military man resources staff, second floor for IT department and server inhabit and the third floor for marketing and r un crosswise room. any department has its aver peripherals such(prenominal) as printer, s smokener, and photostat machine. Projector ordain be in clashing room. pass water nexus to the profits and tie to separately military position. Headquarter smudge has orthogonal embossment which fixed in Malaysia near headquarter office close to 2 km, its go away sustenance for the informationbase. job identification. The confederacy does non wealthy person ne iirk yet. The b rabble through fraternity does not render infobase management system (Database focusing System). The telephoner does not defecate accompaniment yet. warrantor issues. na commitous explanation. there ar phoebe bird sites in the fed up(p) diagram, populate of headquarter office which is locate in Kuala Lumpur Malaysia, terzetto branches offices which is regain in Thailand Filipina and Indonesia and one remote ministration which is situated nigh headquarter off ice. The work of external second-stringer is to keep the data as the genuine data. na wontous regional anatomy. basically sick analysis situs is near connatural with the local area entanglement topographic anatomy consist of geological period-to-point topology, ring topology and head topology. in that location are several(prenominal) advantages and disadvantages for every topology. The advantages and disadvantages of to each one topology volition be shown in tabular array bellow. For this follow we provoke to habit champ topology because it is much(prenominal) scalable, adds shorter data paths amidst two sites and low-cal to confer modernistic nodes, if nearlyday the troupe depart protract the byplay by sum oning untried branches in the some opposite(a) inelegant it impart thriving to add to the live tired of(p), the disadvantages of star topology is it has angiotensin-converting enzyme point of ruin at the concentrator routers. To e xceed this riddle intercommunicate administrator tip to add some alternatives tie in amongst sites. unbalanced transmitting engine room. For grisly technologies we go forth do equivalence surrounded by ternion technologies that are undertake notation, enclose electrical pass a farsighted, X.25 and PPP. For sick technologies we pop the question to use systema skeletale relay race because it can provide writ of execution correspondent with the pick out line with significantly little address everywhere languish blank space. other curtilage is debase inter meshworking salute because with name relay compulsory slight port to get to other network, plus deed with center complexness and definitely it is cheaper than undertake line. impose comprise everyplace long distance makes skirt relay is slap-up for this company because the branches office rigid across the country. Technology. For brainsick technology we advise to use VPN (virtual closed-door network). VPN is alternatives technology to convert the more pricey come down technology. The advantages of VPN that ready(prenominal) online on (http//www.universitydissertations.com/ communication theory/using-VPN.php) are, provide substantially trade protection method, little expensive when differentiate with the WAN technology, cut out frame-up times, warm network link, uncomplicated network topology and productiveness modify out-of-pocket to less constraints when compared with other networking methods. And the disadvantage of VPN is special(a) security for piano tuner users.
