tions that means they have to as well somehow facilitate all remote office workers and team members, internationally, to work together on the similar shared files as well as data at the same time. However, in view of the fact that business data file sizes and data storage needs are augmenting every year, as well as the well-organized sharing of files all through distributed business enterprises over the wide area network (WAN) has turned out to be an exceptional task. Additionally, the difficulty is that gigabytes of data can be shared over a local area network (LAN) through standard file server technology, they cannot be shared all trough remote offices linked over the WAN. On the other hand, standard file server protocols offer unacceptably slow response times to open and write files over the WAN in addition to this forces remote office IT managers to build a number of unappealing alternatives. Thus, in this scenario IT managers and network users have to either live with reduced productivity because of poor network performance at remote offices or they have to make use of replication systems that waste business network storage as well as slow down worldwide collaboration (Dorairajan; Nash; Forouzan and Fegan).
Dorairajan (2004) stated that a new class of product recognized as wide-area file services (WAFS) has demonstrated extraordinary outcomes in resolving the problem of remote office sharing and collaboration intended for distributed organizations and businesses like that Oliyday Hotels. Additionally, the wide-area file services (WAFS) allow corporations with remote offices to make use of the WAN to share files like if it were a virtual LAN, facilitating real-time, read/write access to shared business files in addition to assure the coherency and consistency of the entire business file data (Dorairajan; Forouzan and Fegan). In addition, the majority of the successful WAFS systems tackle inherent WAN file sharing problems through a multi-layered technology
